Title: Devices and methods for remanufacturing printer cartridges

Description:
CROSS REFERENCE TO RELATED APPLICATION 
     This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/343,961, filed May 5, 2010, which is incorporated herein by reference in its entirety. 
    
    
     BACKGROUND 
     a. Field of the Invention 
     The invention relates to devices and methods for remanufacturing printer cartridges, and in particular, to devices and methods for remanufacturing printer cartridges by replacing organic photoconductor (OPC) drums in the printer cartridges. 
     b. Background Art 
     Printer cartridges, such as toner cartridges, are used in various electrophotographic imaging devices, such as laser printers, copiers, facsimile machines, and multifunction imaging devices. Once original equipment manufacturer (OEM) printer cartridges are used, they are often recycled and remanufactured. The process of remanufacturing a printer cartridge may include cleaning the cartridge, repairing damaged parts, replacing worn parts, reassembling with new parts, and replenishing the cartridge with toner. The process of remanufacturing a printer cartridge requires that the printer cartridge be disassembled so that access to the various parts can be achieved, and further requires that the printer cartridge be reassembled for subsequent use. 
     Printer cartridges typically include organic photoconductive (OPC) drums that may be designed to be electrically charged to be able to attract toner. The OPC drum is typically one of the components that wears out from usage and gets replaced during remanufacturing. In some known printer cartridges, such as, for example, some known printer cartridges manufactured by Lexmark International, Inc. for use with Lexmark printer model numbers T650, T652, T654 and E260, E360, E460, the OPC drums may be attached to the printer cartridges in a manner that makes the OPC drums difficult to remove from the printer cartridges and may cause damage to the OPC drum, the OPC drum components, and/or other printer cartridges components during remanufacturing. For example, such known printer cartridges may include a hub assembly comprising a drive hub and a locking ring, where the hub assembly is attached to a drum axle of the OPC drum and helps to lock the OPC drum in place in the printer cartridge. During remanufacturing of such known printer cartridges, known hand tools, such as screwdrivers, pliers, spring hooks, and scraping tools, are typically used to rotate, pry off, and separate the locking ring and drive hub from the drum axle and are used to push out and remove, the locking ring and drive hub in order to remove the OPC drum. However, if not used carefully and properly, such known hand tools can damage the OPC drum, the hub assembly components, and/or other printer cartridge components. In particular, damage to the locking ring and drive hub of the hub assembly can affect or prevent their reuse with a replacement OPC drum. 
     It is thus desirable to be able to remove and replace an OPC drum from a printer cartridge without damage to the OPC drum, the hub assembly components, and/or other printer cartridge components. This helps preserve the appearance of the printer cartridge and minimizes remanufacturing steps. Devices and methods for efficiently and quickly removing and replacing an OPC drum from a printer cartridge are desired. 
     Accordingly, there is a need for an improved device and method for remanufacturing printer cartridges, including replacing OPC drums, that overcomes the issues associated with known devices and methods. 
     SUMMARY

The disclosed embodiments of the devices and methods may be used with printer cartridges that can be used in laser printer models, such as Lexmark International Inc. T650, T652, T654 and E260, E360, E460 families of laser printers, and may also be used with other suitable printer cartridges. 
     Referring to the Figures,  FIGS. 1-3  show a known printer cartridge  10  for which the devices and printer remanufacturing methods of the disclosed embodiments may be applied.  FIG. 1  shows a front perspective view of a front exterior  12  of the known printer cartridge  10 .  FIG. 2  shows a top view of an interior portion  14  of the known printer cartridge  10 , and  FIG. 3  shows a perspective view of the interior portion  14  of the known printer cartridge  10 .  FIGS. 2 and 3  show an organic photoconductor (OPC) drum  16  having a first end  18  and a second end  20 . As shown in  FIG. 2 , the OPC drum  16  has a drum axle  22  having a first end  24  and a second end  26 . The drum axle  22  is positioned substantially within the interior of the OPC drum  16  and runs through the length of the OPC drum  16 . The first end  24  of the drum axle  22  extends beyond the first end  18  of the OPC drum  16 , and the second end  26  of the drum axle  22  extends beyond the second end  20  of the OPC drum  16 . The OPC drum  16  is positioned between sides  28   a ,  28   b  of a waste hopper frame  30  of the printer cartridge  10 . The first end  24  of the drum axle  22  is attached to a hub assembly  32 . The hub assembly  32  comprises a locking ring  34  and a drive hub  36 . The hub assembly  32  is configured to lock and fit snugly within an opening  38  (see  FIG. 3 ) formed in the side  28   a  of the waste hopper frame  30  of the printer cartridge  10 . The opening  38  has one or more locking notches  39  (see  FIGS. 20E ,  24 A). As shown in  FIG. 2 , the hub assembly  32  has an exterior side  40  facing outwardly from the OPC drum  16  and an interior side  42  facing inwardly to the OPC drum  16 . The drive hub  36  is configured to snugly press fit within a recessed interior  44  (see  FIG. 20E ) of the locking ring  34 . The drive hub  36 , as further shown in  FIG. 20E , comprises a central raised portion  46  surrounded by a circular recessed portion  48 , and further comprises a rim portion  50  having notched recessed portions  52 .

The hub assembly  32  is locked into the opening  38  of the side  28   a  of the waste hopper frame  30  and pressed onto the drum axle  22  by a quarter turn locking mechanism that is formed between the opposed locking tabs  57  on the locking ring  34  and the corresponding locking notches  39  formed in the opening  38  of the side  28   a  of the waster hopper frame  30 . The drive hub  36  is pressed onto the first end  24  of the drum axle  22 . When the hub assembly  32  is locked and attached to the first end  24  of the drum axle  22 , the hub assembly  32  locks the OPC drum  16  in place in the printer cartridge  10 . The second end  26  of the drum axle  22  is attached to a bushing  59  (see  FIG. 22E ). 
     As shown in  FIGS. 4-8D , there is provided in a first embodiment a device  60  for remanufacturing a printer cartridge, and in particular, a device for removing and replacing an OPC drum  16  and installing a replacement OPC drum  180  (see  FIG. 24A ).
