Abstract: An image forming apparatus cartridge comprises a guide member, a developing roller having an axis L1, and a coupling member having an axis L2 and at least one projection. A relative positioning of the coupling member and the guide member is changeable between (i) a first relative position in which a tip of the at least one projection is a first distance away from an end of the guide member as measured in the direction of the axis L1 and (ii) a second relative position in which the tip of the at least one projection is a second distance away from the end of the guide member as measured in the direction of the axis L1, with the first distance being greater than the second distance.

Abstract: A replaceable unit for an electrophotographic image forming device includes an electrical contact positioned within a pocket on a first side of a housing of the replaceable unit. The pocket has an opening facing a front of the housing to permit an electrical connector of the image forming device to enter the pocket and mate with the electrical contact. A first guide wall and a second guide wall are each positioned outside the pocket on the first side, in front of the opening. The first and second guide walls each include an inclined surface that inclines outward from the first side of the housing in a direction from the front to a rear of the housing to move the electrical connector of the image forming device toward the circuit board during insertion of the replaceable unit into the image forming device.

Abstract: A method of remanufacturing a toner cartridge includes installing a modified end cap in which a portion of a drive assembly for an internal toner seal removal mechanism has been disabled. With the modified end cap installed, the toner cartridge may be post tested without removing the internal toner seal. When the post test is complete the modified end cap is removed and a non-modified end cap with a functional drive assembly is installed in its place.

Abstract: A replaceable unit for an electrophotographic image forming device includes a body having a toner reservoir. A drive element on a rear end of the body is unobstructed to mesh with a corresponding drive element in the image forming device. A toner outlet port is positioned on a bottom of the body near the rear end of the body. A latch catch is positioned on a first side of the body to receive a corresponding latch when the replaceable unit is installed in the image forming device. A latch actuator at the front end of the body is movable between a home position and a releasing position. A release handle at the front end of the body is operatively connected to the latch actuator such that actuation of the release handle causes the latch actuator to move from the home position to the releasing position to unlatch the body.
