Description

SYSTEMS AND METHODS FOR REMANUFACTURING COMPONENTS OF FORMATION OF IMAGES FIELD OF THE INVENTION The present invention relates in general to the manufacture, remanufacturing or repair of replaceable imaging components, and, more particularly with apparatuses and techniques for replacing a rotating drum or roller, such as an organic photoconductor drum. (OPC), an organic pigment adding roller, a developer roller, a primary charge roller and the like, for example, a replaceable imaging cartridge. In the imaging industry, there is a growing market for the remanufacturing and renewal of various types of replaceable imaging cartridges such as organic pigment cartridges, drum cartridges, ink jet cartridges, and the like. These image-forming cartridges are used in imaging devices such as laser printers, xerographic copiers, inkjet printers, facsimile machines and the like, for example. The image-forming cartridges, once used, are useless for their originally intended purpose. Without a renewal process, these cartridges would simply be discarded, even if the cartridge itself still has potential life.

As a result, specific techniques have been developed to solve this problem. These procedures may involve, for example, the disassembly of the different structures of the cartridge, replacement of the organic pigment or ink, cleaning, adjustment or replacement of any used component and re-assembly of the image forming cartridge. The organic pigment cartridges of laser printers are typically composed of two portions. These sections are the assembly of the waste tray which f houses the OPC drum and the organic pigment hopper which houses the organic pigment addition roller. During the remanufacturing of an organic laser printer pigment cartridge, the OPC drum and organic pigment adding roller may need to be replaced due to wear or damage of the OPC drum and organic pigment adding roller. Typically, the OPC drum is held in place by removable or set plates and the organic pigment roller is held in place with the removable sleeve. The removable plates are typically attached to the waste tray by means of screws which allows a regenerator to easily remove at least one of the removable plates, replace OPC, and reattach the removable plate. This technique allows the replacement of the OPC drum without causing damage to the organic pigment cartridge. In the case of certain organic pigment cartridges, such as the Hewlett-Packard Color LaserJet 2600, the removable plates are not used to secure the OPC drum in place. Instead, the OPC drum is held in place by opposing outer covers, which are not easily removable. These external layers are secured to the waste tray using, among other techniques, the adhesive, which avoids any easy disassembly. However, forcing the removal of the extreme layers causes damage to the end cap and / or the waste tray. This damage results in printing defects when the cartridge has been mounted again because the replacement OPC drum is not securely attached to the waste tray housing as well as changes in the center line of the OPC drum relative to others components of the cartridge, which leads to a rotation out. Additionally, the sleeve for the organic pigment-adding roll is secured in place using an adhesive and removal of this sleeve can result in damage to the sleeve or organic pigment hopper, which can result in printing defects. In this way, the organic pigment cartridge can not be easily disassembled to allow replacement of those components. Therefore, it would be advantageous to provide systems and methods for providing rotating members, such as drums, rolls, and the like in an organic pigment cartridge having elements that retain the rotating member that are securely secured to a portion of the organic pigment cartridge and This mode can not be easily disassembled to allow replacement of the rotating member.
