Description

CLUSTER REPLACEABLE UNIT, XEROGRAPHIC, MODULAR DESCRIPTION OF THE INVENTION This invention relates in general to a customer replaceable unit (CRU = cus omer replaceable unit) for a printing machine and more particularly relates to a photoreceptor module for a eletrophotographic printing machine. In a typical electrophotographic printing process, a photoconductive member is charged to a substantially uniform potential to sensitize its surface. The loaded portion of the photoconductive member is exposed to a light image of an original reproduced document. Exposure of the charged photoconductor member selectively dissipates charges in the irradiated areas. This records a latent electrostatic image on the photoconductive member corresponding to the information areas contained within the original document. After the latent electrostatic image is recorded on the photoconductive member, the latent image is revealed by placing a developing material in contact. In general, the developer material comprises organic pigment particles that adhere triboelectrically to carrier granules. The organic pigment particles are attracted from the carrier granules to the latent image, forming an image of organic pigment powder in the photoconductive member. The organic pigment powder image REF: 26951 is then transferred from the photoconductive member to a copy sheet. The organic pigment particles are heated to permanently attach the powder image to the copy sheet. In printing machines, such as those described above, a CRU is a replaceable unit per customer, which can be replaced by a customer at the end of its useful life or premature failure of one or more of the xerographic components. The CRU concept integrates various subsystems whose durations or lifetimes are predetermined to be the same in general. The CRU's service replacement interval ensures maximum reliability and greatly minimizes unscheduled service calls for maintenance. In using this strategy, they allow customers to participate in the maintenance and service of their copiers / printers. CRUs ensure maximum operating time for copiers and minimize non-operational time and service cost due to end of life or premature failures. It is convenient to have a CRU that allows a variety of machine sub-systems to be incorporated into a single unit while maximizing the life of each component. It is also convenient to use a CRU that allows service to a machine and that is performed efficiently and at a relatively low cost and in some cases it is service by the user. An additional benefit is having the ability to reuse and recycle various CRU components in the current climate of environmental awareness. In accordance with one aspect of the present invention, there is provided a xerographic module for an electrophotographic printing machine comprising a housing, a plurality of xerographic components mounted in the housing and an interlock mechanism mounted in the housing and interconnecting with some of the plurality of xerographic components, wherein when inserting the housing in a printing machine and operating the interlock mechanism with a single actuator, all the plurality of xerographic components are placed in an operative position. Other features of the present invention will be apparent as will be advanced in the following description and with reference to the drawings in which: Figure 1 is a schematic elevation view of a typical electrophotographic printing machine using the unit replaced by the modular xerographic customer of the present invention; Figure 2 is a perspective view of one side of a xerographic CRU; Figure 3 is a perspective view of the opposite side of the CRU of Figure 2, - Figure 4 is an exploded perspective view of the xerographic CRU module that also illustrates its components; Figure 5 is a perspective view of the photoreceptor band unit module; Figure 6 is an end view of the module of the unit of the unit of Figure 5. While the present invention will be described in connection with a preferred embodiment thereof, it will be understood that it is not intended to limit the invention to this embodiment . On the contrary, it is intended to cover all alternatives, modifications and equivalents that may be included within the spirit and scope of the invention as defined by the appended claims. For a general understanding of the features of the present invention, reference is made to the drawings. In the drawings, similar reference numbers have been used throughout the same to identify identical elements. Figure 1 schematically illustrates an electrophotographic printing machine that incorporates the features of the present invention. It will be apparent from the following discussion that the unit replaceable by the modular xerographic client of the present invention can be employed in a wide variety of devices if it is not specifically limited in its application to the particular embodiment described herein. With reference to Figure 1 of the drawings, an original document is placed in a document handler 27 in a scan feed unit (RIS = raster input scanner) generally indicated by reference number 28. The RIS contains lamps for document illumination, optical components, a set of mechanical scanning unit and a set of charge coupled device (CCD = charge coupled device). The RIS captures the entire original document and converts them into a series of scan lines. This information is transmitted to an electronic sub-system (ESS = electronic subsystem) that controls a scanning unit with scan output (ROS = raster ouput scanner) described below. Figure 1 schematically illustrates an electrophotographic printing machine which generally employs a photoconductive strip 10. Preferably, the photoconductive strip 10 is made from a photoconductive material coated in a layer of soil which in turn is coated in a layer of anti-anchoring support. The band 10 moves in the direction of the arrow 13 to sequentially advance successive portions through the various processing stations arranged with respect to the trajectory of their movement. The band 10 is guided with respect to the release roller 14, tension roller 20 and impulse roller 16. As the roller 16 rotates, the band 10 advances in the direction of the arrow 13. Initially, a portion of the foconductor surface passes through. of charging station A. At charging station A, a corona generating device generally indicated by reference number 22, charges the photoconductive band to a relatively high and substantially uniform potential. In an exposure station B, an electronic controller or subsystem (ESS) generally indicated by the reference number 29, receives the image signals representing the desired output image and processes these signals to convert them to a continuous tone or to a representation in grayscale of the image, which is transmitted to a modulated output generator for example the scanning output unit (ROS) generally indicated by the reference number 30. Preferably, ESS 29 is a dedicated self-contained mini-computer . The image signals transmitted to the ESS 29 can originate from an RIS as described above or from a computer, thus allowing the electrophotographic printing machine to serve as a remotely located printer for one or more computers. In alternating form, the printer can serve as a dedicated printer for a high-speed computer. The signals of the ESS 29, corresponding to the image of continuous tones that you want to reproduce by the printing machine, they are transmitted to ROS 30. ROS 30 includes a laser with rotating polygonal mirror blocks. The ROS will expose the photoconductor band to record a latent electrostatic image corresponding to the continuous tone image received from the ESS 29. As an alternative, the ROS 30 can use a linear array of light emitting diodes (LEDs) arranged for illuminating the charged portion of the photoconductive strip 10 on a scan-by-scan basis. After the latent electrostatic image has been recorded on the photoconductive surface 12, the band advances the latent image to a developing station, C, where organic pigment in the form of liquid or dry particles is electrostatically attracted to the latent image using commonly known techniques. The latent image attracts particles of organic pigment from the carrier granules, forming an image of dust or organic pigment on top. As successive latent electrostatic images are revealed, the organic pigment particles become depleted of the revealing material. An organic pigment particle dispenser, indicated generally by reference numeral 39, discharges organic pigment particles in the developer housing 40 of the developing unit 38. With continuous reference to Figure 1, after the electrostatic image is revealed latent, the organic pigment powder image present in the web 10 advances to the transfer station D. A printed sheet 48 is advanced to the transfer station D by a sheet feeding apparatus 50. Preferably, the feeding apparatus of leaves 50 includes a pusher roller 51 which feeds the uppermost sheet of stack 54 to the fastening point 55 formed by feed roller 52 and retard roller 53. Feed roller 52 rotates to advance the sheet from the stack 54 to the vertical transport 56. The vertical transport 56 directs the advancing sheet 48 of the support material in the record transport 120 of the present invention described in detail below, beyond the image transfer station D to receive an image from the photoreceptor band 10 in a synchronized sequence, such that the organic pigment powder image formed thereon contacts the advancing sheet 48 in the transfer station D. The transfer station D includes a corona generating device 58 that sprays ions on the back side of the sheet 48. This attracts the image of organic pigment powder from the photoconductive surface 12 to the sheet 48. The sheet then it is detached from stickiness of the photoreceptor by the corona generating device 59 which sprays oppositely charged ions on the back side of the sheet 48, to aid in removing the sheet from the photoreceptor. After transfer, the sheet 48 continues to move in the direction of the arrow 60 via the conveyor belt 62, which advances the sheet 48 of the fusing station F. The fusing station F includes a fusing assembly generally indicated by the reference number 70 which permanently fixes the image of organic pigment powder transferred to the copy sheet. Preferably, the fusing structure 70 includes a heated fusing roll 72 and a pressure roller 74, with the image of powder on the copy sheet contacting the fusing roll 72. The pressure roller is cammed against the fusing roll, for Provide the necessary pressure to fix the image of organic pigment powder to the copy sheet. The fuser roller is heated internally by a quartz lamp (not shown). Release agent, stored in a tank (not shown) is pumped to a metering roller (not shown). A cutting blade (not shown) trims the excess release agent. The release agent is transferred to a donor roll (not shown) and then to the fuser roller 72. The sheet then passes through the merger 70 where the image is permanently fixed or fused to the sheet. After passing through the merger 70, a gate 80 either allows the sheet to move directly via the outlet 16 to a stacker or terminator, or deflects the sheet in the duplex path specifically, first within the single leaf inverter 82 here . That is, if the sheet is already a simplex sheet or a full duplex sheet that has both images formed on side 1 and side 2, the sheet will be transported via gate 80 directly to output 84. However, if the sheet is to be duplicated and then only printed with an image on one side, the gate 80 will be placed to deflect that sheet in the inverter 82 and to the duplex loop path, where that sheet will be inverted and then fed to the acceleration holding point 102 and band conveying 110 to recirculate back through the transfer station D and fuser 70 to receive and permanently fix the image of side 2 to the back side of that duplex sheet, before it exits through the outlet path 84. After the printed sheet is separated from the photoconductive surface 12 of the web 10, the residual organic pigment / developer and paper fiber particles adhered to the photoconductive surface 12, are removed at the cleaning station E. The cleaning station E includes a fibrous brush rotatably mounted in contact with the photoconductive surface 12 to interrupt and remove paper fibers and a cleaning blade for cleaning Remove the non-transferred organic pigment particles. The blade can be configured in either a cleanser or scalpel position, depending on the application. Subsequent to cleaning, a discharge lamp (not shown) floods the photoconductive surface 12 with light to dissipate any residual electrostatic charge remaining before it is charged for the next successive image formation cycle. The various machine functions are regulated by the controller 29. The controller of preference is a programmable microprocessor which controls all the machine functions previously described. The controller provides a comparison account of the copy sheets, the number of documents that are recirculated, the number of copy sheets selected by the operator, time delays, clogging corrections, etc. The control of all exemplary systems described to date can be achieved by conventional control switching feeds from the consoles of the printing machine selected by the operator. Detectors or switches for conventional sheet paths can be used to track the position of the document and the copy sheets. Turning now to FIGS. 2 and 3, perspective views of the unit replaced by the xerographic client (CRU) 200 are illustrated. The xerographic CRU module 200 assembles and locates xerographic sub-systems in relation to the photoreceptor module 300 and the interphase interfaces. xerographic subsystems. Components contained with the xerographic CRU include the corona generating devices for detachment / transfer 58, 59, the pre-transfer paper baffles 204, the photoreceptor cleaner 206, the charging scorotron 22, the erasing lamp 210, the photoreceptor band (P / R) 10, the multiples for handling noise or only heat and dirt (NOHAD = noise, ozone, heat and dirt) 230 and the filter 240, the waste bottle 250, the drawer connector 260, unit monitor replaceable by customer, CRUM (Customer Replaceable Unit Monitor) 270, the door opening / closing device for automatic disposal and automatic cleaning blade coupling / retraction (not shown). A compendium of xerographic CRU components and the function of each of them is as follows: Cleaner (scalpel 206 and brush disturber 207): remove organic pigment not transferred from the photoreceptor; transport organic pigment from waste and other waste to a waste bottle 250 for storage; they help in controlling the accumulation of talcum powder, film formation and comets in the photoreceptor band. Pre-charge erase lamp 210: provides front irradiation of the photoreceptor to the erasure of the electrostatic field on the surface.

Wire transfer corotron 58: places a load on a piece of paper as when passing under the corotron. The high positive charge on the paper causes the negative charged organic pigment to transfer from the photoreceptor to the paper. Stickiness detachment corotron 59: aid in removing paper with its image from the photoreceptor by neutralizing electrostatic fields that can hold a sheet of paper to the photoreceptor 10. The sheet self-evolves as it passes over a release roller 14 in the 300 web module Multiple NOHAD dirt and filter 240: remove dirt from organic pigment entrained in the air and moving air pollutants before it leaves the CRU. The captured organic pigment and contaminants are deposited in a filter for dirt contained in the xerographic CRU.

The CRU subsystems are contained within the xerographic housing 190. The housing consists of three main components including the front end cap 192, right side housing 194 and left side housing 196. The xerographic housing 190 is a mechanical and electrical link. It establishes critical parameters when mounting and locating internal and external subsystems to the CRU in relation to the photoreceptor module 300 and other interfaces of xerographic subsystems. The housing allows easy installation and reliable separation of the xerographic system without damage or difficulty. The front end cap 192 connects the right-side housing 194 and the left-side housing 194 to each other at the outer end of the CRU 100. The front-end cap 192 also functions as a mechanical link with features that mount and locate on the outside of the housing. the machine the module P / R 200, ROS and log transport in relation to each other in order to achieve critical mechanical parameters. The end cap 192 also assembles pivot pivot, spring door and spring loaded pivot joints (not shown) that allow the customer to simultaneously engage and detach the wiper blade door and the blade during installation and removal of the blade. the CRU, when the handle 315 of the P / R 300 module is rotated as described below. When removed from the machine, the pivot pivot hinge ensures that the wiper blade remains retracted to prevent the P / R 10 band and blade from being damaged during installation and separation from the CRU. the pivot joint for waste door ensures that the door for cleaning waste bottle is closed, when the CRU 200 is removed to avoid spillage of organic pigment during shipment. The end cap 192 also mounts a dirt filtering manifold 230 which links the developer manifold in the left side housing with the NOHAD filth filter 240 in the right side housing 194. The manifolds 230 convey organic pigment entrained by air and other contaminants to the dirt filter 240 by an airflow stream. The right-side housing 192 also assembles and locates a number of xerographic subsystems and internal and external interfaces to the CRU 200. The right-side housing mounts one half of the transfer and detachment structure 400, charging scorotron 22, band P / R 10, and drawer connector 260. These components are allowed to float within the CRU housing. They achieve critical parameter locations with the P / R 300 module and the machine frame, when the CRU 200 housing is fully installed and the handle of the P / R module 315 engages the tension roller 20. Both the charging scorotron 22 as the sticky transfer / detachment subsystem 159 are located by spring loads described in more detail below located on the P / R 300 module. The right side housing 194 also contains molded scorotron retention features and assembles and locates a loading spring that retracts the charge scorotron subsystem to the housing when the CRU is removed from the machine. The spring allows successful installation and removal of the CRU without damage to the cargo scorotron. The right-side housing has molded ports or gates in the loading scorotron mounting area to allow uncontaminated air to circulate over the loading device in order to remove any contaminants that could affect the performance of the unit (i.e. nitrous a cause of blocking eliminations). The right side housing features molded vents at the transfer / stickiness location. The vents also allow sufficient air over the transfer and stick release devices to avoid any contamination of nitrous oxide. The housing has special molded features which assemble and locate the cleaning structures 206, 207, pre-charged erasing lamp 10, waste bottle 250 and air duct NOHAD 230 and filter 240. The right housing mounts and locates the interfaces of the cleaning blade and Pivot features on the waste door. The housing places the NOHAD air duct and filter 240 to the impeller blower, to allow sufficient air flow to capture pollutants entrained by air and pigment. Due to the "load point" power supplies and distributed impellers used in some machines, the blower must be mounted in front of the rear wall of the machine. The system collects airborne pollutants in the manifolds 230 and ducts while pulling the air forward through the CRU 200, the air is then pulled through a filter 240 housed in a pipe-shaped duct in the CRU . This duct configuration provides space for a high capacity transport filter with a large surface area, which removes dirt efficiently for the duration of the CRU. A great advantage is that with every new CRU, fresh filter medium is presented, the dirt is removed with the CRU thereby minimizing the accumulation of dirt in the machine. The blower interface interface duct 295 is shown in Figure 3. The air exiting the blower typically will be directed through the duct through an ozone filter and discharged directly out of the machine. In this system, discharging the air inside the cavity and later collecting it with a fan, allows better deterioration of ozone (as noted above). In addition, this method allows much more efficient ozone filtering due to slower air velocity passing through the ozone filter element, and achieves ozone filtration with just one ozone filter (not all ozone remains within the ozone filter). CRU). Not having an ozone filter at the outlet of the blower also allows the creation of more pressure for a given blower size, cost, energy extraction and certain acoustic interference, thus cleansing the CRU more efficiently. The filter is made of an economical polyester, and it is held with a plastic collar, which creates a seal by crushing the filter medium when it is in place in the CRU. This half filter will be required and the collar will reuse when the CRU is reconditioned. The blower is controlled by software to activate, each time the machine operates and remains on for some period of time after the machine is interrupted to continue purging emissions. The P / R band 10 is partially retained by molded fingers 402 which are located in the inner and outer areas of the right housing. Other retaining band fingers 400 are located in the transfer-side housing and left-side housing. The housing has a molded feature at the outer and lower end, which locates the band on the P / R module to prevent band damage. The left-side housing 196 serves as a protective cover for the P / R band 10 and provides interface windows with various subsystems surrounding the CRU. The interface windows include BTAC 286, developer and ROS. The housing also mounts one half of the transfer tack release subsystem. It also provides an interface window with the log transport for paper input. The developer dirt manifold 230 is also mounted and located in the left-side housing 196. Two of the band retention fingers and a molded feature at the outer and lower end retain and position the P / R 10 band during installation and removal. The left side housing has a molded deflector that covers ROS at the outer end to avoid customer exposure to the ROS beam. The integrated CRU housing has features that ramp the record transport and pre-transport of the merger in position, when the unit is installed in the machine. The CRU housing makes 22 critical mechanical and electrical interfaces almost simultaneously. All accommodations have double enhancements that allow the unit to be held during construction. If both enhancements result in detachment over time, a longer screw may be used to hold the parts due to sufficiently deep enhancements. Turning now to Figures 5 and 6, the module P / R 300 is illustrated, the module generally refers to the reference number 300, it must interface with several subsystems: xerographic loading, image formation, development, paper registration, transfer, cleaning, erasing, two machine racks and xerographic CRUs. The primary function of the unit is to rotate the photoreceptor band (P / R) 10 to the various xerographic subsystems in order to transfer an organic pigment image from the web to a sheet of paper. The photoreceptor module P / R (300) is mounted on the machine frames on the back plate of the machine frames with two fasteners using the mounting holes 303, 305. The image forming backing bar 330 is located in a hole in the backing plate of the machine frames. A second feature, to eliminate rotation is in the rear plate of the P / R module 301. When mounted, the module P / R 300 is cantilevered detached from the back plate of machine frames until the xerographic CRU is inserted in position 200. By rotating the handle of the P / R module 315 clockwise to a substantially vertical position, the tension roller 20 and a developer backup bar 320 contract, allowing the user to insert / remove the Xerographic CRU 200 without interference to the components damage. After the xerographic CRU 200 is fully inserted, the user rotates the handle 315 counterclockwise about 150 degrees to return the tension roller 20 and the developer backing rod 320 to their operative positions. The xerographic CRU 200 locates the P / R 300 module at the rear with an orifice / pin interface 295, 293 between the xerographic CRU 200 and the rear plate 301 of the P / R 300 module. The front interface is also achieved from this However, the pin 297 in the faceplate 302 of the P / R module 300 and the image backup bar 330 in the P / R 300 module are reported by the xerographic CRU 200. The faceplate of the P / R module 302 together with the handle of the module P / R 315 and the edge guides of module P / R 308 have features 309 to direct the band P / R 10 on the front of the structure of the module P / R 300, eliminates the damage to the P / R band due to insertion to the xerographic CRU 200. While the present invention has been described in the context of a black and white photoreceptor CRU, it will be readily apparent that the device can be used in any electrophotographic printing machine where you want ease of service and Service ability by the client. In recapitulation, a xerographic CRU is provided for an electrophotographic printing machine. The xerographic CRU has retained characteristics and cooperates with a pulse module with certain retractable characteristics, which allow the insertion and removal of the CRU without causing damage to the photoreceptor and other critical subsystems. The unit also has many location members for other subsystems, so that critical tolerances are maintained. An interface with a single-handle structure retracts / unlinks and extends / latches the pulse module and the associated CRU subsystems in an operative position. The CRU also has electrical and impulse connections for the cleaning system, the loading and transfer / detachment system. Therefore, it is apparent that a xerographic CRU module has been provided in accordance with the present invention that fully satisfies the previously established objectives and advantages.
