  FIG. 1 shows an ink jet printer 2 including a cradle 4 according to a preferred embodiment of the present invention, which accepts a replaceable print cartridge 6 in a recess formed in its body. ing. The cartridge 6 is secured to the cradle recess by a retainer in the form of a latch 7 which is connected to the cradle 4 by a hinge. On the upper surface of the print cartridge 6, an ink supply port 8 for receiving the ink supply cartridge when used is visible.

[Print cartridge]
Reference is now made to FIG. 2, which shows a block diagram of a removable inkjet printer cartridge 6. The cartridge 6 includes an ink supply port 8 and an ink supply assembly 10 that contains ink and supplies ink to a page-width printhead chip 52 that is a MEMS. The print head chip 52 receives power and data signals from the cradle 4 via the power / data interface 58. The rotor element 60 mechanically driven by the cradle 4 has three sides, each of which sucks the print head chip 52 after firing the ink, seals the print head when not in use, and during printing. Acts as a platen. Thus, the rotor element 60 functions as a printhead auxiliary assembly in helping to maintain the proper functioning of the printhead. The cartridge 6 also includes an authentication device in the form of a quality assurance chip 57, which includes various manufacturer codes that are read by the electronic circuitry of the controller board 82 of the cradle 4 when in use. The manufacturer code is read for the purpose of confirming the authenticity of the cartridge 6.

  Referring to FIGS. 3 to 9, and initially referring to FIG. 6, the structural cartridge 6 has a body including a base molding 20 containing a polyethylene membrane 26, and the polyethylene membrane 26 has four types. Ink reservoirs in the form of pockets 28, 30, 32, 34 for each of the printing fluids are included. The printing fluid is typically cyan ink, magenta ink, yellow ink, and black ink. Additional storage reservoirs may be provided within the base molding 20 for the purpose of receiving and storing ink fixer and / or infrared ink that may be required in various applications. In this regard, the base molding 20 can be provided with a maximum of six receiving reservoirs. The membrane 26 expands when filled with printing fluid, and conversely breaks down as ink is consumed during printing.

  Cover molding 36 includes a recess 38 that receives ink inlet molding 24 having a plurality of passages. A plurality of openings 42 </ b> A to 42 </ b> E are formed in the recess 38, and these openings communicate with the corresponding passages of the ink injection port molding 24. The passage of the ink inlet member conveys ink from the ink supply cartridge attached from the outside to each of the ink storage reservoirs through a series of ink supply paths formed in the ink membrane 26. In the ink supply path, the openings 42A to 42E of the ink inlet member 24 are coupled to the dedicated ink storage reservoirs 28 to 34, respectively. Ink is generally supplied under pressure, thereby flowing into the reservoir of the membrane 26 and expanding the reservoir. The ink inlet seal 40 is disposed outside the recess 38 for the purpose of sealing the openings 42A to 42E before use.

  The page width print head chip 52 is disposed along the outside of the base molding 20 of the cartridge in a region below the ink storage reservoir. As shown in FIG. 7, a plurality of conduits 43 </ b> A to 43 </ b> E are formed on the lower side of the base molding of the cartridge, and these are in direct communication with each of the ink storage reservoirs 28, 30, 32, and 34. Yes. These conduits provide an ink supply path from the underside of the cartridge base molding 20 to the inlet port provided in the ink supply molding 48 to which the printhead chip 52 is attached.

  Referring again to FIG. 6, the ink supply molding 48 is preferably made from a plastic such as LCP (Liquid Crystal Polymer) by an injection molding process and distributes the printing fluid from the reservoir in the membrane 26 to the printhead chip 52. A plurality of elongated conduits that are adapted to be disposed along the longitudinal direction of the ink supply molding 48. Each of the elongate conduits can carry a specific fluid (such as a specific color ink or fixer) dedicated and distribute that fluid along the length of the printhead. An ink seal strip 45 is disposed between the base molding 20 of the cartridge and the ink supply molding 48 to assist in supplying the printing fluid under control. The ink seal piece has a hole through which fluid can move between these two elements, but this seal piece has a groove formed in the base molding of the cartridge to prevent fluid leakage. Serves to seal.

  An air flow groove 50 is formed in the base molding 20 of the cartridge next to the elongated ink distribution conduit so that the pressurized air from the suction port 76 flows over the nozzles of the print head 52. To work. The air circulation groove exists along the longitudinal direction of the print head 52 and communicates with the air suction port 76. The porous air filter 51 extends along the longitudinal direction of the air circulation groove 50 and removes dust and particulate matter that are present in the air and may contaminate the print head 52 if not removed. . The porous air filter 51 is porous so that only air at the desired threshold pressure can pass through it so that the air is evenly distributed at a constant pressure along the length of the print head. Supplied. In use, the groove 50 is initially filled with compressed air until the threshold pressure in the groove is reached. When the threshold pressure is reached, air can pass through the porous air filter 51 uniformly along the length of the filter. The filtered air is then directed onto the print head.

  The purpose of the pressurized air is to prevent the print head from deteriorating by maintaining the nozzle in the absence of dust and debris. Pressurized air is supplied by an air compressor (element 122 in FIG. 14) incorporated in the cradle 4. The compressor air nozzle (element 124 in FIG. 15) passes through the air seal 44 when the cartridge 6 is inserted into the cradle 4 and is coupled to the suction port 76. The air cover plate 54 is fixed to the base molding of the cartridge, and distributes air uniformly throughout the print head 52 as described above.

  The print head 52 is supplied with power and data signals by a bus bar 56 coupled to external data and power connectors 58A and 58B. An authentication device in the form of a quality assurance (QA) chip 57 is attached to the connector 58A. When the printer cartridge 6 is inserted into the cradle 4, the data / power connectors 58A, 58B and the QA chip 57 are coupled with the corresponding connectors (elements 84A, 84B in FIG. 9) in the cradle 4, so that the cradle and cartridge are connected. It is possible to transmit power and data between them. The QA chip 57 is tested in use by a portion of the controller board 82 that is configured to function as a suitable verification circuit.

  The rotor element 60 is rotatably mounted in parallel and adjacent to the print head 52. The rotor element has three sides as briefly described above, i.e., a platen surface that functions as a support for the print media during printing and assists in transporting the print media near the print head 52; A capping surface that covers the print head when not in use and a blotter surface that sucks the print head after printing operation for the purpose of reducing evaporation of the printing fluid from the nozzles. The three faces of the rotor element are each separated by 120 degrees.

  Extending from both ends of the rotor element 60 are axial pins 64A and 64B to which teeth 62A and 62B are fixed, respectively. Free ends of the axial pins 64A and 64B are received in the sliding blocks 66A and 66B. Sliding blocks 66A and 66B include flanges 68A and 68B disposed in slots 70A and 70B of end plates 22A and 22B. The end plate is fixed to both ends of the base molding 20 of the cartridge.

  The sliding blocks 66A and 66B are biased toward the print head side ends of the slots 70A and 70B by springs 72A and 72B held at both ends, which are slid to the sliding blocks 66A and 66B. By inserting springs into the blind holes and seating these springs in the slots 70A and 70B over the protrusions (most obvious in FIG. 8). Thus, normally, the rotor element 60 is biased and is adjacent to the print head 52.

  The rotor element 60 has a capping surface that covers the print head 52 in order to prevent the nozzles of the print head from being dried by ambient air during transportation and while the printer cartridge 6 is inserted into the cradle 4. Has been.

[Print head]
Next, a preferred design of the page width print head 52 will be described. The following types of printheads can be made with widths greater than 8 inches if required, and generally include at least 20,000 nozzles, and in variations, more than 30,000 nozzles. Yes. Hereinafter, a preferred arrangement structure of the print head nozzles provided with the nozzles and the corresponding actuators will be described with reference to FIGS. FIG. 19 shows a series of nozzle structures 801 formed on a silicon substrate 8015. Although these nozzle structures are the same, in a preferred embodiment, different color inks and fixers are sent to different nozzle structures. Note that the rows of the nozzle structure portions 801 are staggered, whereby the interval between the ink dots during printing can be made narrower than possible when the nozzles are arranged in a row. Multiple rows can also provide redundancy (if necessary), which allows a predetermined failure rate per nozzle.

  Each nozzle structure 801 is manufactured by an integrated circuit manufacturing technique. Specifically, the nozzle structure 801 is a MEMS (micro electro mechanical system).

  Hereinafter, the structure and operation of one nozzle structure portion 801 will be described with reference to FIGS.

  The inkjet printer chip 12 includes a silicon wafer substrate 801. A 0.35 micron, 1 P4M, 12 volt CMOS microprocessor circuit is disposed on a silicon wafer substrate 8015.

  A silicon dioxide (or glass) layer 8017 is disposed on the wafer substrate 8015. This silicon dioxide layer 8017 defines a CMOS dielectric layer. The top metal of the CMOS defines a pair of aligned aluminum electrode contact layers 8030 disposed on the silicon dioxide layer 8017. Both the silicon wafer substrate 8015 and the silicon dioxide layer 8017 are etched to define an ink suction path 8014 having a substantially circular cross section (in plan view). In the silicon dioxide layer 8017, CMOS metal 1, CMOS metals 2 and 3, and an aluminum diffusion barrier 8028 of the CMOS topmost metal are disposed around the ink suction path 8014. The diffusion barrier 8028 serves to prevent hydroxyl ions from diffusing through the CMOS oxide film of the driving circuit layer 8017.

  A passivation layer in the form of a silicon nitride layer 8031 is disposed on the aluminum contact layer 8030 and the silicon dioxide layer 8017. Each portion of the passive layer 8031 located above the contact layer 8030 has an opening 8032 that provides access to the contact 8030.

  The nozzle structure 801 includes a nozzle chamber 8029 defined by an annular nozzle wall 8033, the upper end of which is located on the nozzle roof 8034, and the radially inner nozzle edge 804 ( Is circular in the plan view). The ink suction path 8014 is in fluid communication with the nozzle chamber 8029. A moving edge 8010 including a moving seal lip 8040 is disposed at the lower end of the nozzle wall. The surrounding wall 8038 surrounds the movable nozzle and includes a stationary seal lip 8039. The stationary seal lip 8039 is adjacent to the moving edge 8010 when the nozzle is stationary as shown in FIG. Due to the surface tension of the ink trapped between the stationary seal lip 8039 and the moving seal lip 8040, a fluid seal 8011 is formed. This provides a low resistance coupling between the surrounding wall 8038 and the nozzle wall 8033, but prevents ink leakage from the nozzle chamber.

  As best seen in FIG. 17, the roof 8034 defines a plurality of indentations 8035 extending radially about the nozzle edge 804. The recess 8035 serves to accommodate the radial ink flow as the ink flows over the nozzle edge 804.

  The nozzle wall 8033 forms part of the lever structure attached to the carrier 8036, the carrier 8036 has a substantially U-shaped profile, and its bottom 8037 is attached to the silicon nitride layer 8031.

  The lever structure also includes a lever arm 8018 that extends from the nozzle wall and incorporates a lateral reinforcement beam 8022. The lever arm 8018 is made of titanium nitride (TiN) and is attached to a pair of passive beams 806 located on one side of the nozzle structure (most apparent in FIGS. 13 and 18). The other end of the passive beam 806 is attached to the carrier 8036.

  The lever arm 8018 is also attached to an actuator beam 807 made of TiN. Note that this attachment to the actuator beam is performed at a position slightly higher than the position attached to the passive beam 806 by a significant distance.

  As best seen in FIGS. 13 and 16, the actuator beam 807 is substantially U-shaped in plan view and defines a current path between the electrode 809 and the opposite electrode 8041. Each of the electrodes 809 and 8041 is electrically connected to a respective point in the contact layer 8030. The actuator beam is mechanically fixed to the anchor 808 in addition to being electrically coupled via the contact 809. Anchor 808 is configured to constrain actuator beam 807 from moving to the left in FIGS. 10-12 as the nozzle structure operates.

  The TiN of the actuator beam 807 is conductive, but has sufficient electrical resistance to generate heat when a current flows between the electrode 809 and the electrode 8041. No current flows through the passive beam 806, so the passive beam 806 does not expand.

  In use, a stationary device is filled with ink 8013, which defines a meniscus 803 under the influence of surface tension. The ink is held in chamber 8029 by the meniscus and generally does not leak out unless some other physical effect is present.

  As shown in FIG. 11, in order to eject ink from the nozzle, a current flows between the contact 809 and the contact 8041, and at this time, it flows through the actuator beam 807. The beam 807 generates heat due to its resistance and thereby expands. The dimensions and design of the actuator beam 807 mean the majority of the horizontal expansion in FIGS. Expansion is constrained on the left by anchors 808, thus the end of actuator beam 807 adjacent to lever arm 8018 advances to the right.

  Since the passive beam 806 has a relatively small horizontal flexibility, the passive arm 806 prevents the lever arm 8018 from moving largely horizontally. However, the position where each of the passive beam and the actuator beam is attached to the lever arm is deviated, so that a torsional motion occurs, and the lever arm 8018 moves substantially downward due to this. This movement is substantially a pivoting movement or a hinge movement. However, since there is no true turning center, the center of rotation is the turning area defined by the bending of the passive beam 806.

  The downward movement (and slight rotation) of the lever arm 8018 is amplified by the distance from the passive beam 806 to the nozzle wall 8033. As the nozzle wall and the roof move downward, the pressure in the chamber 29 increases, which causes the meniscus to swell as shown in FIG. The fluid seal 11 is extended by this movement without leakage of ink due to the surface tension of the ink.

  As shown in FIG. 12, the drive current stops at an appropriate timing, and the actuator beam 807 cools rapidly and contracts. By contraction, the lever arm begins to return to its rest position, thereby reducing the pressure in chamber 8029. Due to the interaction between the momentum of the expanding ink and the surface tension as the liquid, and the negative pressure due to the upward movement of the nozzle chamber 8029, the expanding meniscus becomes thinner and eventually cut off. 802 is defined and this drop of ink continues to rise until it touches the adjacent print media.

  Immediately after the drop 802 is cut off, the meniscus 803 forms the concave shape shown in FIG. Due to the surface tension, the pressure in the chamber 8029 remains relatively low until the ink is sucked upward through the suction port 8014, and when sucked, the nozzle structure and the ink return to the stationary state shown in FIG.

  As is most apparent in FIG. 13, the nozzle structure also incorporates a test mechanism that can be used periodically after manufacture and after installation of the printhead. The test mechanism includes a pair of contacts 8020 connected to a test circuit (not shown). A finger 8043 extending from the lever arm 8018 is provided with a bridging contact 8019. Since the bridging contact 8019 is opposite the passive beam 806, when the nozzle is activated, the bridging contact moves upward and contacts the contact 8020. The test circuit can be used to confirm that the circuit formed by the contacts 8019 and 8020 closes upon actuation. If the circuit closes properly, it can generally be assumed that the nozzle is operating.

[Cradle]
FIG. 20 is a functional block diagram of the printer cradle 4. The printer cradle is built around a controller board 82 that includes one or more custom small office home office printer engine chips (SoPEC), and details about the architecture of this chip Will be briefly described later. The controller board 10 is coupled to a USB port 130 for connection to an external computing device such as a personal computer or digital camera that contains the digital file to be printed. Furthermore, the controller board 10 monitors the following.
A paper sensor 192 that detects the presence of a print medium
A printer cartridge chip interface 84 that is coupled to the QA chip 57 of the printer cartridge when in use
Ink supply cartridge QA tip contact 132 coupled to the QA tip of the ink supply cartridge (shown as element 176 in FIG. 37) in use.
A rotor element angle sensor 156 that detects the orientation of the rotor element 60

In use, the controller board processes data received from the USB port 130 and the various sensors described above, and in response drives the motor 110 and the tricolor indicator LED 135 via interface 84. Then, the print head chip 52 is driven. As will be described in more detail later, a motor 110 is mechanically coupled to drive a plurality of mechanisms that provide ancillary services for the print cartridge 6. Examples of the mechanism to be driven include the following.
A rotor element drive assembly 145 for operating the rotor element 60
A print media transport assembly 93 that feeds the print media across the print head chip 52 during printing
An air compressor 122 that supplies compressed air to maintain the print head chip 52 free of debris.

  As briefly described in detail later, the motor 110 is coupled to each of the above mechanisms by a transmission assembly that includes a direct drive coupling from the motor shaft to the impeller of the air compressor; Worm gear and toothed transmission to the rotor element and print media transport assembly.

  Next, the structure of the cradle 4 will be described with reference to FIGS. As is most apparent in the exploded view of FIG. 26, the cradle 4 has a body shaped complementary to the cartridge 6 such that when coupled to the cartridge 6 forms an ink jet printer. The cradle body is formed of a base molding 90 and a cradle molding 80. The base molding functions as a support for the cradle and houses the drive motor 110, the rotor element roller 94, and the drive roller 96. The base molding is coupled and fixed to the cradle molding 80 by a plurality of corresponding flanges 120 and slots 123. The cradle molding 80 defines an elongated indentation 89 having a size for accommodating the print cartridge 6. The inner wall of the cradle is formed with a plurality of recesses in the form of slots 86 that receive complementary projections in the form of ribs 78 (FIG. 4) of the cartridge 6. As a result, in order to fully accommodate the cartridge 6 in the cradle molding 80, the cartridge 6 must be oriented correctly. In addition, this slot allows the only slot that can be inserted into the cradle to be supported by the cradle's electronics, so that the cartridge does not collide with the ribs, so that the cradle's drive electronics have unsupported performance characteristics. The problem of trying to drive the cartridge is overcome. The controller 82 examines the performance characteristics of the cartridges inserted into the cradle 4 and operates each cartridge in response to the examined performance characteristics. As a result, it is possible to upgrade by providing a starter cartridge with relatively basic performance characteristics in the inkjet cradle and then replacing the starter cartridge with a higher performance upgrade cartridge when needed. is there. For example, the upgrade cartridge can print faster than the starter cartridge or can support more ink.

  Referring to FIG. 25, a worm gear 129 that meshes with the teeth 125 </ b> B is attached to the end of the drive shaft 127 of the motor 110, and the teeth are fixed to the drive roller 96. Referring to FIG. 26 again, the drive roller is supported by bearing mount assemblies 100A and 100B at both ends, and the assemblies 100A and 100B are fixed to the slots 101A and 101B of the cradle molding 80. Similarly, the rotor element conversion roller 94 and the pinch roller 98 are also supported by the bearing mount assemblies 100A and 100B.

  Referring now to FIG. 30, a flipper gear assembly 140 is disposed on the opposite side of the motor end of the drive roller 96. The flipper gear assembly comprises a housing 144 that holds an inner gear 142 and an outer gear 143 that mesh with each other. The inner gear 142 is fixed coaxially with the drive roller 96, whereas the housing 144 rotates freely around the drive roller 96. In use, the housing rotates with the drive roller 96 and the outer gear 143 until the outer gear 143 hits a stopper located on the base molding 90 of the cradle or the outer gear 143 meshes with the rotor element drive teeth 146. Rotate with The rotation direction of the drive roller 96 depends on the direction of the drive current that is passed to the motor 110 by the control board 82. When the outer gear 143 and the rotor element drive teeth 146 mesh, a rotor element drive assembly 145 comprising a drive roller 96, an inner gear 142, an outer gear 143, and a rotor element drive tooth 146 is formed. As a result, in this configuration, power can be transmitted from the drive roller 96 to the rotor element drive roller 94.

  Referring to FIG. 31, cams 148 </ b> A and 148 </ b> B disposed on corresponding cam followers 150 </ b> A and 150 </ b> B are attached to both ends of rotor element driving roller 94. Cam followers 150A and 150B are ring-shaped, and are pivotally fixed by pivot pins 152A and 152B on one side, respectively. The hinged jaws 154A and 154B are provided to grip the rotor element sliding blocks (elements 66A and 66B in FIG. 6) of the printer cartridge. The jaws are pivotally coupled to cam followers 150A and 150B, respectively, on opposite sides of pins 152A and 152B. As the rotor element drive roller 94 rotates, the cams 148A and 148B abut against the inner walls of the cam followers 150A and 150B, thereby lifting the cam followers with the jaws 154A and 154B, respectively.

  In order to rotate the rotor element 60 by the correct angle, the cradle 4 includes a rotor element sensor unit 156 (FIG. 20) that detects the actual orientation of the rotor element. The sensor unit 156 includes a light source and a detector unit that detects the presence of reflected light. The rotor element 60 has a reflective surface adapted to reflect light from the light source so that the orientation of the rotor element can be detected by the sensor 156. Specifically, by monitoring the sensor unit 156, the controller board 82 can determine which surface of the rotor element 60 is adjacent to the print head 52.

  In addition to the drive roller 96, the motor 110 also drives an air compressor 122 that includes a fan housing 112, an air filter 116, and an impeller 114. The fan housing 112 includes an air outlet 124 that is adapted to couple with an air intake port 76 (FIG. 6) of the cartridge 6.

  As is clear from the side view of FIG. 25 and the cross section of FIG. 27, a metal backplane 92 is fixed to the rear surface of the cradle molding 80. A control board 82 on which various electronic circuits are mounted is attached to the backplane 92. The control board is covered by a metal radio frequency interference (RFI) shield 102. Control board 82 is electrically coupled to cradle connectors 84A and 84B via flexible PCB connector 106, and is also coupled to an external data and power connection point in the form of USB port connector 130. The USB connector 130 allows connection to an external personal computer or other computing device. The cradle connectors 84A and 84B are supported in slots formed at both ends of the cradle molding 80 so that when the printer cartridge 6 is fully inserted into the cradle molding recess 89, the cartridge connectors 58A and 58B. Electrical contact is made.

  Controller board 82 is connected to QA chip contacts 132 by various cable rooms and flexible PCB 106. The QA chip contact is disposed in a recess 134 formed in the cradle molding 80 so as to come into contact with the QA chip 176 disposed in the ink supply cartridge 162 when ink is replenished, as will be briefly described later. Is arranged.

  The controller board 82 also drives a tricolor indicator LED (element 135 in FIG. 20) that is optically coupled to the light pipe 136. The end of the light pipe is attached to an indicator port 138 formed in the cradle molding 80 so that the light from the tricolor indicator LED can be seen from the outside of the casing.

[Controller board]
A printer apparatus according to a preferred embodiment of the present invention includes, as basic structural parts, a cradle assembly (including all necessary electronic circuits), a part necessary for handling power and paper, and a cartridge unit. Of these, the cartridge unit includes a highly specialized print head and a portion necessary for handling ink. Therefore, one cradle unit can support cartridge units having different performance and functions without the need to purchase a new cradle unit.

In this regard, a series of cartridge units each having a plurality of different functions and performances can be provided. For example, in a simple form, it will be possible to provide the following three types of cartridge units.
・ Starter unit: 15ppm cartridge with 150ml ink capacity ・ Standard unit: 30ppm cartridge with 300ml ink capacity ・ Professional unit: 60ppm cartridge with 300ml additional ink capacity

  Such a system can be supported in one cradle unit, and the user can purchase various cartridge units depending on his requirements and cost.

  In the case of a professional unit, it may be necessary to provide a dedicated cradle unit that supports the advanced and advanced functions of such a cartridge unit. The cartridge unit having various functions can be provided with a mark such as a color code marking so that the compatibility with the cradle unit can be easily recognized.

  In this regard, FIG. 32 shows a main PCB unit for a cradle unit operating at 15-30 ppm, and FIG. 33 shows a main PCB unit driving a cartridge unit operating at 60 ppm. As is apparent from the figure, these PCBs are nearly identical, the main difference being that there are two SoPEC chips in the 60 ppm PCB. Therefore, even if a user purchases a cradle unit that does not initially support a stronger cartridge unit, the system structure of the present invention allows the cradle unit to be easily upgraded to support such a system. .

  The printer is application specific print engine pipeline control logic configured to perform one or more SoC (system on chip) components and some or all of the functions described above associated with the print pipeline. It is preferable that these are further included.

  Referring now to FIG. 34, the SoPEC device is broadly divided into three different subsystems: a CPU (Central Processing Unit) subsystem 301, a DRAM (Dynamic Random Access Memory) subsystem 302, and a print engine pipeline. (PEP) subsystem 303.

  The CPU subsystem 301 includes a CPU 30 that controls and sets all aspects of other subsystems. This subsystem provides general support for interface processing between an external printer and an internal print engine and for synchronization processing between them. This subsystem also controls low speed communication with the QA chip (described in another paragraph of this specification). The CPU subsystem 301 also includes various peripheral devices that support the CPU, such as general-purpose I / O (GPIO: including motor control), interrupt controller unit (ICU), LSS master timer, and general-purpose timer. A serial communication block (SCB) on the CPU subsystem provides a full speed USB 1.1 interface with the host and an inter-SoPEC interface (ISI) with other SoPEC devices (not shown).

  The DRAM subsystem 302 receives requests from the CPU, serial communication block (SCB), and blocks in the PEP subsystem. The DRAM subsystem 302, specifically the DRAM interface unit (DIU), arbitrates various requests and determines which request should be assigned access to the DRAM. Based on the set parameters, the DIU arbitrates so that all requesters are allowed sufficient access to the DRAM. In addition, the DIU hides the specifications for mounting the DRAM such as the page size, the number of banks, and the refresh rate.

  A print engine pipeline (PEP) subsystem 303 receives compressed pages from DRAM and sends them to a printhead interface that communicates directly with up to two segments of the bilithic printhead. Convert to gradation dots. The first stage of the page expansion pipeline consists of a continuous tone decoder unit (CDU), a lossless two-tone decoder (LBD), and a tag encoder (TE). It is. Among them, CDU develops a continuous tone (generally CMYK) layer that is JPEG compressed, LBD develops a compressed two tone layer (generally K), and TE renders later ( In general, a netpage tag is encoded for infrared ink or K ink. The output from the first stage is a series of buffers: a continuous tone FIFO unit (CFU), a spot FIFO unit (SFU), and a tag FIFO unit (TFU). The CFU buffer and the SFU buffer are mounted on the DRAM.

  The second stage is a halftone synthesizer unit (HCU), which dithers the continuous tone layer and places the position tag and dither on the resulting dithered two tone layer. A two-tone spot layer is synthesized.

  Depending on the print head used with the SoPEC device, multiple synthesis options can be implemented. From this stage, 2 gradation data of a maximum of 6 channels are generated. However, not all channels need to exist in the print head. For example, the print head can be CMY only, K can be pushed into the CMY channel, and IR can be ignored. Alternatively, if IR ink is not available (or for testing purposes), the encoded tag can be printed in K.

  In the third stage, a defective nozzle corrector (DNC: Dead Nozzle Compensator) corrects defective nozzles in the print head by color redundancy and error diffusion of defective nozzle data to surrounding dots.

  The resulting two-gradation, six-channel dot data (generally CMYK, infrared, fixing agent) is stored in a buffer, and a series of data stored in DRAM by a dot line writer unit (DWU). Written to the line buffer.

  Finally, dot data is loaded from the DRAM and passed to the printhead interface via the dot FIFO. The dot FIFO receives data from the line loader unit (LLU) at the system clock rate (pclk), while the print head interface (PHI) deletes the data from the FIFO and the system clock rate. It is sent to the printhead at a rate 2/3 times that of the printhead.

  In a preferred form, the DRAM is 2.5 Mbytes in size, about 2 Mbytes of which can be used for compressed page store data. The compressed page is received in two or more bands, and a plurality of bands are stored in the memory. Once the page bandwidth is consumed by the PEP subsystem 303 for printing, a new bandwidth can be downloaded. This new band is the band of the current page or the next page.

  By using the bandwidth method, it is possible to start printing the page before the entire compressed page is downloaded, but care must be taken that the data to be printed is always available. Otherwise, a buffer underrun may occur.

  The embedded USB 1.1 device receives the compressed page data and control commands from the host PC and transmits the data to the DRAM (to another SoPEC device in a multi-SoPEC system as described below). Enable.

  In alternative embodiments, multiple SoPEC devices can be used, and multiple SoPEC devices can perform various functions depending on the particular embodiment. For example, in some cases, one SoPEC device can simply be used for on-board DRAM, while another SoPEC device is used for the various decompression and data formatting functions described above. To do. This can reduce the possibility of a buffer underrun, where the printer starts printing the page before all the data on the page has been received and the remaining data is not received in time. Can happen. Adding additional SoPEC devices for memory buffering capabilities doubles the amount of data that can be stored in the buffer, even if the additional capabilities of the added chip are not utilized.

  Each of the SoPEC systems guarantees the quality of the printer structure, the quality of the ink supply (so as not to damage the printhead nozzles during printing), and the quality of the software (so as not to damage the printhead and structure). Multiple quality assurance (QA) devices that are designed to cooperate with each other.

  Normally, each print SoPEC is associated with a printer QA that stores printer attribute information such as the maximum print speed. The ink cartridge used in this system also includes an ink QA chip, and this chip stores cartridge information such as the remaining amount of ink. In addition, the print head has a QA chip that is configured to function as a ROM (actually as an EEPROM), which provides information specific to the print head, such as mapping of defective nozzles and print head characteristics. Storing. As an option, the CPU in the SoPEC device can actually load and execute program code from a QA chip that functions as a serial EEPROM. The CPU in the SoPEC device executes a logical QA chip (ie, a software QA chip).

  Normally, all QA chips in the system are physically the same, and only the contents of the flash memory are different from each other.

  Each SoPEC device has two LSS system buses that can communicate with the QA device for system authentication and ink usage calculations. Multiple QA devices can be used per bus, and the location of QA devices in the system is not limited, with the exception that printer QA devices and ink QA devices should be on separate LSS buses. .

  In use, the logic QA communicates with the ink QA and examines the remaining ink. The response from the ink QA is authenticated with reference to the printer QA. The confirmation from the printer QA is itself authenticated by the logical QA, which indirectly adds an additional authentication level to the response from the ink QA.

  Data passed between QA chips other than the print head QA is authenticated by a digital signature. In the preferred embodiment, HMAC-SHA1 authentication is used for the data and RSA is used for the program code, but other schemes could be used instead.

One SoPEC device can control two bilithic print heads and up to six color channels. The six channels of color ink are the maximum numbers expected in a personal office (SOHO) or office bilithic printing environment and include:
-CMY (cyan, magenta, yellow): for normal color printing-K (black): for black text, line graphics, and grayscale printing-IR (infrared): for Netpage compatible applications-F (fixing agent): Enables high-speed printing by preventing bleeding of printed matter

  Because bilithic printers can print at very high speeds, a fixer may be required to dry the ink before another page touches the already printed page. If the fixing agent is not used, ink may bleed between pages. In relatively slow printing environments, a fixer may not be necessary.

  In the preferred embodiment, the SoPEC device is independent of color space. Continuous tone data as CMYX or RGBX (X is an optional fourth channel) can be accepted, but continuous tone data in any print color space can also be accepted. In addition, SoPEC provides a mechanism for arbitrarily mapping input channels to output channels, such as combining dots to optimize ink, or creating channels based on any number of other channels. However, in general, the input is CMYK for continuous tone input and K for two tone input, and optional Netpage tag dots are typically rendered in the infrared layer. Fixer channels are typically generated for high speed printing applications.

  In the preferred form, the SoPEC device is also independent of resolution. In SoPEC devices, the mapping between input resolution and output resolution is simply provided by the scale factor. The predicted output resolution for the preferred embodiment is 1600 dpi, but SoPEC does not actually have information on the physical resolution of the bilithic printhead.

In the preferred form, the SoPEC device is independent of page length. Successive pages are generally divided into multiple bands and downloaded to the page store as each band of information is consumed.

[Ink supply cartridge]
As described above, the print head cartridge 6 includes the ink containing membrane 26 including the internal ink reservoirs 28 to 34, and the ink reservoirs 28 to 34 are ink supply ports formed on the upper surface of the cover molding 36. 8 is connected. For the purpose of replenishing the reservoirs 28-34, an ink injector in the form of an ink replenishment cartridge as shown in FIGS. 35-42 is provided. Hereinafter, the structure of the replenishment cartridge 160 will be described with reference mainly to FIG. 37 which is an exploded view of the cartridge.

  The ink cartridge 160 has an outer molding 162 that functions as an operating handle or “plunger” and includes an inner spring assembly 164. The spring assembly 164 includes a base 178, and a spring member 180 extends from the base and contacts the inside of the cover molding 162. The spring member urges the base 178 against the deformable ink membrane 166, and the ink membrane 166 is generally made of polyethylene and contains a printing fluid such as color ink or fixing agent. The ink membrane 166 is housed in a polyethylene base molding 170 that slides within the outer molding 162, as best seen in FIGS. The ink outlet pipe 182 extends from the membrane 166 and fits in an elastomeric collar 172 formed at the bottom of the base molding 170. A seal 174 covers the collar 172 before using the ink supply cartridge.

  Extending from the bottom of the base molding 170 is a protrusion 190 that functions as a positioning feature and has a shape that mates with a refill port of an inkjet printer component (such as the ink refill port 8 of the printer cartridge 6). The position of the outlet pipe 182 and the collar 172 relative to the protrusion 190 will vary depending on the type of printing fluid included in the ink supply cartridge. Accordingly, a printing fluid system is provided that includes a plurality of printing fluid injectors each having an outlet disposed with respect to the protrusion 190 depending on the type of printing fluid to be received. As a result, when a refill cartridge is coupled to port 8, outlet 182 is coupled to the corresponding inlet 42A-42E, and thus a specific reservoir reservoir 28, 30 that is dedicated to contain the same type of printing fluid. , 32, 34 are replenished.

  A flange 184 extends from one side of the bottom of the base molding 170, and an authentication means in the form of a quality assurance (QA) chip 176 is attached to the flange 184. When the ink cartridge 160 is inserted into the ink supply port 8, the QA chip 176 comes into contact with the QA chip contact 132 disposed on the cradle 4.

  Extending from the outer wall of the base molding 170 is a retaining projection 168 that is received in a recess that is either a pre-push indent 165 or a post-push indent 169. As shown in FIGS. 37 and 38, these recesses are formed on the inner periphery of the wall of the upper cover molding 162. The indentation recess 165 is disposed near the opening of the upper cover molding, while the indentation recess 169 is disposed above the inner wall. When the ink cartridge 160 is completely filled, the holding protrusion 168 engages with the depression 165 before pushing. As will be explained more concisely later, in order to overcome this engagement, an indentation force greater than a predetermined threshold must be carefully applied to the upper cover molding. The ink is pumped out of the outlet 172 by the push, and the base molding 170 enters the upper cover molding 162 by overcoming the bias of the spring assembly 164 until the retaining protrusion 168 is received in the recess 169 after the push.

[Example of use]
In use, the printer cartridge 6 is properly aligned on the cradle 4 as shown in FIG. 3 and then inserted into the recess 89 of the upper cradle molding 80. When the cartridge unit is inserted into the cradle 4, the data / power contacts 84A and 84B of the cradle are electrically connected to the data / power contacts 58A and 58B of the cartridge 6. At the same time, the air nozzle 124 of the air compressor assembly 122 passes through the air seal 44 and enters the air intake port 76 of the cartridge 6.

  As is apparent in FIG. 27, a pedestal or shelf on which the cartridge is placed after insertion is formed on the inner wall of the recess 89. A plurality of elastic members in the form of springs 190 are provided which act on the cartridge when the cartridge is in place and when the retention latch is secured over the cartridge. It also acts on the holding latch. As a result, these springs function to hold the cartridge firmly in the cradle 4 and latch 7 by absorbing the shock upon insertion and then urging the cartridge in place into the latch. . In the alternative, a spring can be placed in the latch 7, in which case the cartridge 6 is biased against the cradle 4.

  An attempt to insert the cartridge in the wrong direction is not possible due to the presence of a specific orientation slot 86 in the cradle 4 and a specific orientation rib 78 in the cartridge 6. Similarly, cartridges that are not intended for use with the present cradle are not acceptable in any orientation because they do not have ribs that correspond to slots 86 in a particular orientation. In particular, cartridges that need to be driven by a cradle with a dual SoPEC chip controller board do not have the correct rib shape to be received by a cradle with a single SoPEC chip controller board.

  When the cartridge unit is first inserted into the cradle unit 4 and during transport, the rotor element 60 is oriented such that its capping surface engages the print head 52 so that the nozzle opening of the print head is sealed. . Similarly, when the printer apparatus is not used, the capping surface is in contact with the bottom for the purpose of sealing the bottom of the print head 52. Sealing the print head reduces the evaporation of the ink solvent, usually water, and therefore reduces the drying of the ink at the print nozzles while the printer is not in use.

  Remote computing devices such as digital cameras and personal computers are connected to the USB port 130 for the purpose of supplying power and print data signals to the cradle 4. The processing circuit of the controller board 82 executes various initialization routines in response to the supply of power, for example, confirms the manufacturer code stored in the QA chip 57, and sets the status of the ink reservoirs 28 to 34 to the ink reservoir. Check unit status by tricolor indicator LED 135, check by sensor 35, check status of rotor element 60 by sensor 156, check by paper sensor 192 whether paper or other print media is inserted in cradle It is shown to the outside through the pipe 136.

  Before performing the printing operation, paper or other print media must be fed into the cradle 4. When the controller board 82 receives a signal for starting printing from an external computing device, the controller board 82 checks the presence of the sheet by the sheet sensor 192. If no paper is present, the tricolor LED 135 is set to call attention and the controller does not start printing. However, if the paper sensor 192 indicates that print media is present, the controller board 82 responds by rotating the rotor element 60 to a predetermined print position.

  In this regard, when a printing mode of operation is detected at startup or during a maintenance routine, the rotor element 60 rotates so that its blotting surface is located in the ink firing path of the print head 52. The blotting surface functions as a kind of spitton and can receive ink from the printing nozzles, and the received ink is contained in the body of the rotor element 60 due to the absorption characteristics of the material provided on the blotting surface. Be drawn. Since the rotor element 60 is a part of the printer cartridge 6, the rotor element 60 is replaced when the cartridge is replaced. As a result, ink does not accumulate on the suction surface and become dirty.

  When a print command is detected at the USB port 130 and the presence of the print medium is confirmed, the controller board 82 drives the motor 110, whereby the drive roller 96 starts rotating and cooperates with the pinch roller 98 to print medium. Is fed into the print head 52. At the same time, the controller board 82 processes print data from an external computing device for the purpose of generating control signals for the print head 52. Control signals are passed to the printhead via cradle interfaces 84A, 84B, cartridge interfaces 58A, 58B, and flexible PCB contacts at both ends of the printhead chip 52. The printhead chip 52 is bilithic, i.e. comprises two elongated chips that span the length of the printhead, and data is fed to both ends of the printhead, with individual lengths along the length of each chip. Transmitted to each of the nozzles. Power is supplied to individual nozzles of the printhead chip via bus bars extending along the length of the chip. The individual nozzles of the print head are responsive to the received data and power to selectively fire ink onto the print media as it is drawn over the platen surface of the rotor element 60, thereby providing a USB port. The image encoded in the data signal transmitted to 130 is printed.

  The operation of motor 110 causes air compressor 122 to direct air to the base molding of the cartridge. The air is guided to the space behind the air filter 51 through the fluid supply path in the base molding 20 of the cartridge. When the air pressure increases to a level that sufficiently overcomes the resistance of the air filter 51, the air is directed out through the holes in the air filter 51 along the length of the bottom of the cartridge base molding. The guided air is received between the print head chip 52 and the air cover plate 54 and passes over the surface of the print head chip while the printer is operating, thereby free of dust and debris. By maintaining the print head, the print head is prevented from deteriorating.

  Referring now to FIG. 40, the first step in the ink replenishment procedure begins with the replenishment sensor 35 telling the controller board 82 that there is a shortage of printing fluid in the reservoirs 28, 30, 32, 34. Is done. Controller board 82 activates indicator LED 135 in response to a signal from replenishment sensor 35. Alternatively, detection of the lack of printing ink can be calculated by the controller board electronics. The volume of ink per nozzle firing is known and constant throughout the printhead operation (approximately 1 picoliter), so the amount of ink supplied by the printhead and the consumption of each color or type of ink The quantity can be calculated. In this regard, the controller board 82 can monitor the consumption of each printing fluid, and when that level reaches a predetermined level, the tricolor indicator LED must be activated to replenish that printing fluid. Can be notified to the user.

  Light from the indicator LED is conveyed by a light pipe 136 for the purpose of displaying information at the indicator port 138 of the cradle 4 to the printer operator. This information can tell the user the color or type of ink that needs to be replenished. The controller board can also send a signal to the remote computing device via the USB port 130 to indicate to the user through the computing device the type of ink that needs to be refilled.

  In order for the replenishment procedure to proceed, the printer cartridge 6 must be in a predetermined position on the printer cradle 4. Next, the ink supply cartridge 160 of the necessary ink type is moved over the ink supply port 8 disposed on the upper surface of the printer cartridge 6. As described above, the ink supply port 8 includes a series of injection ports 42 </ b> A to 42 </ b> E protected by the sealing film 40. Beneath the sealing film 40 are a plurality of printing fluid conduits 43A-43E that are in direct communication with the ink reservoirs 28, 30, 32, 34. An ink inlet is provided for each of the printing fluids, ie, C, M, Y, K, infrared ink, and fixing agent (if necessary). The position of the inlet of each of the different fluids is such that the ink outlet pin 182 of the replenishment cartridge 160 automatically matches the inlet corresponding to the particular printing fluid to be refilled included in the cartridge 160 among the inlets 42A-42E. Are arranged in a specific arrangement order along the injection port 8 so as to communicate with each other.

  The second stage of the ink supply stage is shown in FIG. In this figure, a supply cartridge 160 is inserted into the supply port 8 of the cartridge unit. When the supply cartridge 160 is inserted into the supply port 8, the positions of the ink supply QA chip 176 and the QA contact 132 of the cradle unit automatically match. The controller board 82 examines various codes stored in the QA chip 176 for the purpose of verifying the integrity and authenticity of the ink supply cartridge 160. When controller board 82 determines that the presence of genuine ink, i.e., the ink of the required color or type from the correct manufacturer, is confirmed by QA chip 176, indicator LED 135 shines yellow. , Thereby indicating that the refill cartridge 160 has been received. However, if controller board 82 determines that an error condition exists, controller board 82 sets LED 135 to red for the purpose of notifying that there is a problem with the refill cartridge. For example, when the QA chip 176 does not pass the confirmation step, it can be determined that an error condition exists. Furthermore, often only one of the reservoirs 28, 30, 32, 34 needs to be refilled. For example, a reservoir assigned to contain cyan ink may require replenishment. In that case, if the QA chip 176 indicates that the ink supply cartridge 160 does not contain cyan ink, the controller board 82 sets the indicator LED 135 to red for the purpose of notifying an error condition.

  It will be appreciated that communication between all parts of the printer device is required to provide replenishment that ensures quality assurance. That is, the printer cartridge 6 must be disposed in the printer cradle 4 and the ink supply cartridge 160 must be inserted into the cartridge 6 such that the ink supply QA chip 176 contacts the QA chip contact 132. . This controls each of the refill operations and reduces the possibility of false refills that can damage the printer mechanism.

  As shown in FIG. 41, when the ink supply cartridge 160 is inserted into the supply port 8 of the cartridge unit 6, the ink outlet pin 28 penetrates the sealing film 40, and one of the supply port openings 42 to A42E is filled with ink. It communicates with a corresponding one of the inlets 24. The ink inlet 24 is formed as an elastomer molding so that penetration of the ink seal 32 (located ahead of the outlet pin 28 of the ink supply cartridge) occurs automatically. As a result, fluid communication (self-sealing fluid communication) in a sealed state is ensured between the ink stored in the replenishment cartridge 160, the ink supply conduits 43A to 43E, and the storage reservoirs 28 to 34. . As a result of the fluid communication in the sealed state, when the outer molding 162 is pushed, pressure causes ink to flow into one of the reservoirs 28, 30, 32, 34.

  As shown in FIG. 42, when the upper cover molding 162 is pushed, the third stage of the ink replenishment procedure occurs, and the ink present in the ink replenishment cartridge 160 is stored in the reservoirs 28-34 of the printer cartridge. Extruded into one. After the outer molding 162 is pushed, it is clear to the operator that the ink supply cartridge 160 has been emptied, and this supply phase is now complete and the cartridge 160 can be removed from the printer cartridge 6. When this replenishment phase is complete, the replenishment sensor 35 generates a signal indicating that the level of printing fluid in each of the reservoirs 28-34 exceeds a predetermined level. In response to the signal from the replenishment sensor, the controller board 82 sets the indicator LED 135 to glow green, thereby notifying the operator that the replenishment process has been completed successfully.

  The force with which ink is pushed out from the ink supply cartridge 160 is determined by the degree of pushing force applied to the upper cover molding 162 by the operator. Accordingly, the upper cover molding 162 functions as an operation handle or a plunger of the ink supply cartridge. As a result, if the replenishment step is not performed carefully or is performed quickly, ink may be supplied to the printer cartridge 6 at an excessively high pressure. Due to such pressure, the ink containing membrane 26 may be ruptured by the ink contained in the printer cartridge 6, and thus the ink may leak inside the cartridge unit and damage the printer cartridge to such an extent that it cannot be repaired. . The internal spring molding 164 prevents inadvertent rupture of the membrane by providing a safety mechanism against excessive pressure of ink pushed out of the refill unit. In this regard, the spring molding 164 is designed to limit the maximum force transmitted to the deformable ink membrane 26 by pushing the upper cover molding 14. As a force applied to the upper cover molding 14, a force that causes ink to be pushed out at a pressure exceeding the maximum allowable level is absorbed by the spring molding 164 and accumulated in the spring member 180. The spring molding 164 is suitably designed to prevent an excessive force from being momentarily applied to the replenishment ink membrane 166. That is, the deformation and / or elastic properties of the spring molding 164 are selected such that the pressure in the membrane is limited to a predetermined level.

  As shown most clearly in FIGS. 38 and 39, a holding projection 168 is disposed on the side surface of the base molding 170. While the ink cartridge 160 is in a state before being pushed in, the holding projection 168 is coupled to the depression 165 before being pushed in. Engagement of the protrusion 168 with the pre-push indentation provides an additional safety measure during the refill process. This engagement prevents an unintended force from being applied to the inner ink membrane 166 from the upper cover molding, and thus prevents the upper cover from being inadvertently pushed during transportation or delivery. After the ink supply cartridge 160 is inserted into the supply port 8, the upper cover 162 is pushed in with a force sufficient to overcome the engagement between the depression 165 before pushing and the holding protrusion 168. As the upper cover molding 162 is pushed, the base 178 of the spring assembly 164 strikes the ink membrane 166, thereby pushing ink through the outlet pipe 182 into the ink reservoir membrane 166 of the printer cartridge. In order to overcome the initial engagement of the retaining protrusion 168, a large force must first be applied. The spring member 164 functions instantaneously so as to prevent excessive pressure from being applied to the ink membrane 166 in this case. Following the application of this initial force, it proceeds to normal pushing. As shown in FIG. 38, when the replenishment step is complete, the retaining projection 168 engages the locking shape in the form of a post-indent recess 169, which is the upper side of the inner wall of the outer molding 162 of the ink cartridge. Is arranged. The holding protrusion 168 is coupled to the upper recess 169 so that the ink is pushed out, and then the outer molding 162 of the ink cartridge is fixed to the base molding 170. It will be appreciated that this arrangement overcomes the possibility of a user attempting to refill the ink supply cartridge 162 with low quality ink that could damage the nozzles and ink supply cartridges of the printer cartridge. In this state after pushing, the used ink supply cartridge can be returned to the supplier. The supplier is provided with a tool to open the refill cartridge and return the top cover to the upper position, so that the refill unit is refilled with authentic ink so that it can be reused and the authenticity of the ink is confirmed. The QA chip 176 can be reprogrammed.
