Cover member 110 can form single piece component effectively, and its length perhaps can be formed by the short part of the length that links to each other corresponding to the length of the printhead for the treatment of capping, and the length overall of the short part of described length is corresponding to the length of printhead.When the embodiment that is used for shown in Fig. 8 and 9, cover member 110 will be combined with purge chamber 91, and when being used for the embodiment of Figure 10 and 11, cover member 110 will be integral to or be installed to pivoted frame 97 and 101.And when being used for the embodiment of Figure 12, cover member 110 will form as one with pivotal arm 104.
Referring now to Figure 14 to 23 one of them print head chip 57 is described in more detail.
As mentioned above, each print head chip 57 is provided with 7680 printing-fluid delivery nozzles 150.Nozzle arrangement becomes 12 row 151,640 nozzles of every row, and wherein the spacing X between the nozzle is 32 microns.Half the distance that adjacent lines stagger one and equal spacing between the nozzle makes the nozzle in the delegation be arranged in the centre of two nozzles of adjacent lines.Simultaneously, the injector spacing Y between the adjacent nozzles row is 80 microns.
Two row adjacent nozzles 150 are by a common printing-fluid feeding mechanism supply printing-fluid.The layout that this utilization is staggered and making is compared with possible the spacing of single row of nozzles when printing, and the ink dot spacing is more compact, permission redundancy to a certain degree simultaneously, and described redundancy is with respect to the situation of nozzle fault.
Print head chip 57 is by the ic manufacturing technology manufacturing, and as mentioned above, print head chip all comprises MEMS (MEMS).Each print head chip 57 comprises a silicon wafer substrate 152, is formed with 12 volts of CMOS micro-processor interface circuits of 0.42 micron 1 P4M on this wafer.Thereby silicon dioxide layer 153 is deposited on the substrate 152, and as dielectric layer, and aluminium electrode contact layer 154 is deposited on the silicon dioxide layer 153.Etch substrate 152 and layer 153 are limiting black groove 155, and aluminium diffusion barrier 156 is provided with around black groove 155.
The passivation layer 157 of silicon nitride is deposited on al contact layer 154 and the layer 153.The passivation layer 157 that part is positioned on the contact layer 154 has the opening 158 that is positioned at wherein, so that the inlet towards contact layer to be provided.
Each nozzle 150 comprises nozzle box 159, described nozzle box by nozzle wall 160, nozzle top 161 and radially inner nozzle edge 162 limit.China ink groove 155 is communicated with chamber 159 fluids.
Comprise that the movable edge 163 of sealing lip 164 movably is positioned at the lower end of nozzle wall 160.Surrounding wall 165 holds nozzle and static sealing lip 166 is provided, and when nozzle was static as illustrated in fig. 19, described sealing lip 166 was adjacent with movable edge 163.Owing to the surface tension that is trapped in the China ink between standstill seal lip 166 and the removable sealing lip 164 forms fluid sealing 167.This has prevented that China ink from oozing out from indoor, and low-resistance couple of force connection is provided between surrounding wall 165 and nozzle wall 160 simultaneously.
Nozzle wall 160 has formed a part that is installed in the leverage on the support 168 that is roughly the U-shaped profile, and support 168 has the base portion 169 that is attached to layer 157.Leverage also comprises lever arm 170, and described lever arm is from the nozzle wall extension and be combined with horizontal buttress brace 171.Lever arm 170 is attached on a pair of driven beam 172, and described driven beam is formed and be positioned at each side of nozzle unit by titanium nitride, and is best shown in Figure 18 and 22.The other end of driven beam 172 is attached to support 168.
Lever arm 170 also is attached to the actuation beam 173 that is formed by TiN.This and actuation beam attached is formed on a position, described position than the attachment location with driven beam 172 exceed one little, but very important distance.
Best shown in Figure 18 and 21, actuation beam 173 roughly is U-shaped in vertical view, defines current path between electrode 174 and comparative electrode 175.Each electrode 174 and 175 all is electrically connected to the corresponding position in the contact layer 154.Actuation beam 173 also mechanically is fastened on the anchoring piece 176, and anchoring piece 176 is configured to: when spray nozzle device is worked, and the left motion of anchoring piece restriction actuation beam 173 in Figure 15 to 17.

When operation, nozzle is filled with China ink 177, and described China ink defines meniscus 178 under capillary influence.China ink remains in the chamber 159 by described meniscus, and can not ooze out usually when not having other physical action.
For from the nozzle ejection China ink, electric current passes through between contact 174 and 175, the actuation beam 173 of flowing through.Beam 173 oneself's heating cause beam to expand, and the size and dimension of actuation beam 173 so designs: beam mainly expands along the horizontal direction of Figure 15 to 17.Anchoring piece 176 restrictions are toward the expansion in left side, thereby the end of actuation beam 173 contiguous lever arms 170 is pushed to the right side.
The relative non-deformable of driven beam 172 along continuous straight runs prevents that it from allowing lever arm 170 to carry out big horizontal movement.Yet driven beam and actuation beam have caused twist motion with the relative displacement of the attachment point of lever arm separately, and described twist motion causes lever arm 170 by pivoting action or rotatablely move and generally move downward again.Yet do not exist real pivotal point to mean rotating is to wind to be undertaken by the pivotal area that bending limited of driven beam 172.
Lever arm 170 move downward (and slightly rotating) amplified by the distance between nozzle wall 160 and the driven beam 172.The moving downward of nozzle wall and top causes the pressure in the chamber 159 to increase, and caused meniscus 178 projection as illustrated in fig. 16, yet the surface tension of China ink makes fluid sealing 167 do not allowed oozing out of China ink by this motion tensioning.
As shown in figure 17, at the reasonable time place, drive current stops, and actuation beam 173 promptly cools off and shrinks.Contraction causes lever arm to turn back to resting position, and this causes the pressure in the chamber 159 to reduce again.The momentum of China ink of projection and the interaction between its intrinsic surface tension and cause carefully contracting of protruding meniscus 178 and final disconnection by the negative pressure that moving upward of nozzle box 159 caused, the print media thereby formation ink droplet 179, described ink droplet continue to move upward until the contact process.
And then after ink droplet 179 separates, the concave surface that meniscus 178 forms as shown in Figure 17.Surface tension makes the pressure in the chamber 159 keep relatively low, up sucks by inlet 155 until China ink, and this makes spray nozzle device and China ink return to inactive state shown in Figure 15.
Best print head chip 57 also is combined with mechanism for testing as Figure 18 finding, can use this mechanism for testing termly after using this mechanism for testing after the manufacturing and print head assembly is being installed.Described mechanism for testing comprises a pair of contact 180 that is connected to the test circuit (not shown).Bridge joint contact 181 is arranged on from the finger 182 of lever arm 170 extensions.Because bridge joint contact 181 is positioned at the opposite side of driven beam 172, the actuating of nozzle causes bridge joint contact 181 to move upward to contact 180 contacting.Test circuit can be used for confirming to activate the closure that causes this circuit that is formed by contact 180 and 181.Ifs circuit is correctly closed, can think usually that then nozzle is work.
As mentioned above, the integrated circuit of print head chip 57 is by print engine controller (PEC) the integrated circuit control of drive electronics 63.Be provided with one or more PEC integrated circuits 100 (depending on needed print speed), to allow the carrying out page width printing on the page of various different sizes or on the continuous paper.As mentioned above, each is carried and four print head chips, 57 interactional PEC integrated circuits 190 (Figure 24) by the printed circuit board (PCB) 62 that supports moulded parts 66 carryings.PEC integrated circuit 190 mainly drives the integrated circuits of print head chips 57, and the print data that receives is sent in the print head chip with the form that is suitable for printing.
U.S. Patent application 09/575 co-pending in the applicant, 108 (files numbering PEC01US), 09/575,109 (files numbering PEC02US), 09/575,110 (files numbering PEC03US), 09/607,985 (files numbering PEC04US), 09/607, described among 990 (files numbering PEC05US) and 09/606,999 (the files numbering PEC07US) and be applicable to the PEC integrated circuit example that drives print head chip, be introduced into for your guidance at this.Yet, hereinafter be briefly described with reference to Figure 24 to 26 pair of circuit.
Data handling procedure and the operation carried out by PEC integrated circuit 190 in the following situation are described: wherein be provided with the PEC integrated circuit has a plurality of printhead modules 55 with driving printhead 51; Be four modules as described above.Simultaneously, as mentioned above, each printhead module 55 provides six fluid passages that are used to print, and these passages are:
Be used for cyan, purplish red and yellow (CMY) that common color is printed;
The black (K) that is used for surplus and other black or gray level printing;
Infrared (IR) that can be used for marker field; And
Fixative (F) is printed at high speed allowing.
As shown in figure 24, image offers PEC integrated circuit 190 by computer, computer programming and carried out each relate to the treatment step 191 to 194 that image is printed before being sent to PEC integrated circuit 190.In the buffer memory that these steps are usually directed to receive view data (step 191) and these data are stored in computer system (step 192), in this step, can produce the object that image layout also can add any needs.Before being sent to PEC integrated circuit 190, the space of a whole page that comes from buffer memory is compressed (step 194) then by rasterisation (step 193).When receiving view data, PEC integrated circuit 190 deal with data, thereby the integrated circuit of driving print head chip 57.
Because the page width characteristic of print head assembly, each image all should be printed to avoid forming visible distortion phenomenon with constant speed.This means that should change print speed matches with the speed with the input data.Therefore, the printing decoupling zero of the rasterisation of file and file is to guarantee that print head assembly has constant data and supplies with.In this is provided with, Cai it is printed by complete rasterisation up to image, and in order to obtain very constant print speed, the compressed format of each rasterisation page-images is stored in the internal memory.
Because produced continuous-tone image and the literal and the bargraphs of black directly reproduce by point by colour combination at random, so the picture format after the compression comprises prospect two-value black layer and background continuous tone layer separately.After the continuous tone layer is carried out colour combination, black layer is synthesized on this continuous tone layer.If necessary, alternatively final mark layer (printing with IR or tusche) is added on the image to be used for printout.
Colour combination matrix in the iamge description selects the zone to be turned to the bitonal bitmap of continuous tone resolution by grating, and this bitonal bitmap nondestructively is compressed to can uncared-for size and form the part of compressed image.The IR layer of printer page comprises the programmable coded markings of density alternatively.
Each compressed image is sent to PEC integrated circuit 190, and at described PEC integrated circuit 190 places, compressed image is stored in the buffer memory 195 then.Recover this compressed image then and supply to image spreading device 196, in this image spreading device, recover image.If necessary, can any colour combination be applied on any continuous tone layer and by synthesizer 198 by colour combination device 197 any black two-value layer is synthesized on the continuous tone layer, infrared markers can be played up by rendering device 199 arbitrarily simultaneously.PEC integrated circuit 190 drives the integrated circuit of print head chip 57 then, to print the composograph data in step 200 to produce print image 201.
Can think that PEC integrated circuit 190 performed processes comprise a plurality of different stages.Phase I has the ability of the continuous tone CMYK layer of expansion JPEG compression.Parallel therewith, can be from the compressed image two-value IR flag data of encoding.Second stage is carried out colour combination by the colour combination matrix to continuous tone CMYK layer---and described colour combination matrix selects mapping to select by the colour combination matrix, and if necessary, and the two-value black layer is synthesized on the formed two-value K layer, and the IR layer is added on the image.All need part in C, M, Y, K or IR passage, produce the fixation layer in the each point position.Final stage is printed the CMYK+IR data of two-value by print head assembly 50.
Figure 25 illustrates the relation of PEC integrated circuit 190 in whole print system framework.Each parts of described framework comprise:
PEC integrated circuit 190, its page-images of being responsible for receiving compression are used for being stored in buffer memory 202, carry out page expansion, black layer is synthetic and point data is delivered to print head chip 57.PEC integrated circuit 190 can guarantee that also (QA) integrated circuit 203 communicates by letter, and communicates by letter with print cartridge quality assurance (QA) integrated circuit 204 with principal mass.PEC integrated circuit 190 also provides the device that recovers the print head assembly feature to guarantee optimum the printing.
Buffer memory 202, it is used for store compressed image and temporary when printing the given page.The structure of buffer memory and work are known for those skilled in the art, and can adopt a series of standard integrated circuit and technology.
Master integrated circuit 203, itself and print cartridge QA integrated circuit 204 mate.The structure of QA integrated circuit and work also are known for those skilled in the art, and can adopt a series of known QA program.
PEC integrated circuit 190 is carried out four other functions of main level effectively:
Serial line interface by for example IEEE 1394 receives compressed page.
Be used as print engine to produce image from compressed format.The function of print engine comprises expanded images, the continuous tone layer is carried out colour combination handles, black layer is synthesized on the continuous tone layer, adds infrared markers alternatively and the image that obtains is delivered in the integrated circuit of print head chip.
As the stepper motor 102,108 and 111 of print control unit with control print head chip 57 and print system.
The low-speed serial port that is used as two standards is to communicate by letter with two QA integrated circuits.In this regard, adopted two ports rather than a port to guarantee the high degree of safety in authenticating step.
Describe these functions in further detail referring now to Figure 26, Figure 26 provides the more clear and definite exemplary illustration to the PEC integrated circuit structure.
PEC integrated circuit 190 is combined with simple microcontroller CPU nuclear 204 to carry out following function:
Carry out the QA integrated circuit authentication protocol by the serial line interface between the print image 205.
The stepper motor that moves print system by parallel interface 206 during printing prints with the conveying of control print media to printer.
Make each parts of PEC integrated circuit 190 synchronous during printing.
Device (programming register etc.) with the external data request interface is provided.
Device (for example reading characteristic vector and recording impulse profile) with the low speed data request interface of print head assembly is provided.
The device that the mark structure of portrait painting effect and landscape painting effect is recorded outside DRAM 207 is provided.
For carries out image expansion and print routine, PEC integrated circuit 190 comprises that tag encoder 212, the line of half look/synthesizer (HC) 211, the customization of HSSI High-Speed Serial Interface 208 (for example standard IEEE 1394 interfaces), standard jpeg decoder 209, standard G4FAX decoder 210, customization are written into/format device (LLF) 213 and the print head interface 214 (PHI) of communicating by letter with print head chip 57.Decoder 209 and 210 and tag encoder 212 serve as the buffer memory of HC 211.Tag encoder 212 is assigned to infrared markers on the image.
Print engine functionality is with the form work of double buffering.That is to say that an image is loaded into outside DRAM 207 by DRAM interface 215 and data/address bus 216 from HSSI High-Speed Serial Interface 208, and read the image that before had been written into and this image is handled through print engine from DRAM 207.After image was printed out, the image that was written into just now becomes treated print image, and new image is written into by HSSI High-Speed Serial Interface 208.
In the above-mentioned phase I, described process is launched all JPEG compression continuous tone (CMYK) layer, and launches in the two-value data stream of two G4FAX compressions any one.These two data flow are black layer and delustring layer, between two colour combination matrixes, to select with the continuous tone colour combination.In second stage, with the phase I concurrently, all marks are encoded to play up with IR China ink or tusche subsequently.
At last, in the phase III, the continuous tone layer is carried out colour combination, and position mark and two-value point layer is synthesized on the two-value colour combination layer that is obtained.Regulate data flow ideally with the level and smooth transition of formation on the lap of print head assembly, and ideally, regulate data flow with the idle nozzle in the compensation print head assembly.In this stage, produce the nearly two-value data of six passages.
Yet, it will be appreciated that not every six passages all need work.For example, printhead module 55 can only be used for CMY, and K is pushed in the CMY passage and omits IR simultaneously.Alternatively, if do not use the IR China ink, then position mark can be printed with K.The two-value CMYK-IR point data that is obtained is buffered and formats, to print by the integrated circuit of print head chip 57 via a series of line buffer memory (not shown).Great majority in these line buffer memorys can be stored among the outside DRAM207 ideally.In stage in the end, print six passages of two-value point data by PHI 214.
HC 211 is combined to half look function of continuous tone (being generally CMYK) layer on its two-value form, and will put 1 two-value layer and be synthesized on the half suitable look continuous tone layer.If there is not the K China ink, then HC 211 works and makes the K point suitably be mapped to the CMY point.It also based on the colour combination matrix select mapping respective value and between two colour combination matrixes individual element ground select.The colour combination matrix of 1 layer of the two-value point that is input as continuous tone layer (from jpeg decoder 205) by the expansion of buffer memory 217, the expansion by buffer memory 218 of HC 211, the expansion by buffer memory 219 is selected bitmap---and this colour combination matrix is selected the resolution ratio of bitmap and the continuous tone layer is roughly the same and the flag data that passes through the peak resolution ratio of buffer memory (FIFO) 220.
HC 211 uses nearly two the colour combination matrix that reads from outside DRAM 207.The output that outputs to LLF 213 from HC211 be one group of printer respectively rate, be arranged in bianry image line up to six color planes.Normally, the continuous tone layer is CMYK or CMY, and the point of two-value is K for 1 layer.In case open, HC 211 operates the condition that detects " image termination " until it, perhaps ends clearly by the control register (not shown) until it.LLF 213 is from HC 211 acceptance point information, the point that will be used for given print line is written into suitable buffer memory (some buffer memorys are arranged in (not shown) on the integrated circuit and some are positioned at outside DRAM 207), and with the needed order of the integrated circuit of print head chip 57 it is formatd.More specifically, word that is input as 32 of hexads and the data significance bit of LLF 213, they produce by HC 211.
As mentioned above, the physical location of nozzle 150 on print head chip is the row 151 of two biasings, this means that the odd point of same color is used for two different row with the even number point.In addition, between the point of a kind of point of color and another color, there are a plurality of row.Side by side calculate by HC 211 because be used for six colour planes of identical point position,, be positioned at suitable color nozzle below until identical point so need to postpone to be used for the point data of each colour plane.The size of each buffering row depends on the width of print head assembly.Can adopt single PEC integrated circuit 190 to produce and be used for the nearly point of 16 print head chips 57, thereby in this case, 640 points that single odd number or the behavior of even number buffering are 16 groups are total up to 10240 (1280 bytes).
PHI 214 is so a kind of devices: PEC integrated circuit 190 is controlled by a next point to be printed is loaded in the print head chip 57 and to the dot printing process of reality of this device.It obtains input and data is outputed to print head chip 57 from LLF 213.PHI 214 can handle the length and the form of multiple print head assembly.
Each print head assembly 50 and 51 assemblage characteristic vector can read back by serial line interface 205.Characteristic vector can comprise not the information of main jet and the align data of associated print head module.Each printhead module can be inquired about by low-frequency serial bus 221, to return the characteristic vector of printhead module.
The characteristic vector that comes from a plurality of print head assemblies can make up and be formed for the nozzle fault list of whole print head assembly, and allows PEC integrated circuit 190 in print procedure defective nozzle to be compensated.As long as the quantity of defective nozzle is low, compensation can produce the effect as broad as long with the print head assembly of zero failure nozzle.
