Laser printer cartridge

In a two piece toner cartridge assembly, as typically used in a computer and/or facsimile printing device, comprising separable photoconductor and developer units a unique coupling device is provided whereby the cartridge assembly may be removed from the printing device without the photoconductor unit separating from the developer unit for paper jam clearance or unit replacement. However, if desired the developer unit may be separately removed from the printing device for servicing or replacement without removal of the photoconductor unit.

Coupling mechanism for a two piece printer cartridge

A bracket to mount a charge roller and a blade against a photoconductive drum within an image forming apparatus. Bracket may include a pair of guides that extend outward to receive the ends of the charge roller. A biasing device may be positioned to bias the charge roller against the photoconductive drum. The guides may include an opening sized to allow the charge roller to move and maintain contact with the photoconductive drum. A mounting surface may be positioned on the bracket for receiving adhesive to mount the blade. In one embodiment, the bracket is constructed of an electrically conductive material such that a charge introduced to the bracket is delivered to the charge roller.

Multi-function cleaner blade assembly

The invention provides a test fluid for detecting coating flaws in a coated web and a method for testing a web coating system. The test fluid includes, water, a polyol, a surfactant, a radiant energy activated tracer compound and an organic solvent selected from the group consisting of an alkylene glycol and a dialkylene glycol. The test fluid is used to identify deficiencies in the web coating system so that adjustments to the web coating system may be made before assembling the coating system in an ink jet printer.

Paper coating test method and composition

An ink jet printer is provided comprising a housing, an ink jet printing apparatus and a coating apparatus. The ink jet printing apparatus is located within the housing and includes an ink jet printing device capable of ejecting ink droplets onto a first side of a printing substrate which moves through the housing along a printing substrate feed path. The coating apparatus is positioned along the printing substrate feed path and spaced from the printing device. The coating apparatus applies a substantially uniform layer of coating material onto at least a portion of the first side of the printing substrate.
