A replaceable imaging basket for an electrophotographic image forming device according to one embodiment includes a frame having a positioning slot that is open at a top of the frame for receiving a replaceable unit. An electrical connector is positioned on an inner side of the frame adjacent to the positioning slot. The electrical connector includes an electrical contact on a front of the electrical connector that faces the positioning slot. The electrical connector includes a pair of outer guides and a pair of inner guides on opposite sides of the electrical contact. The inner guides are spaced inward from the outer guides. A top portion of a front surface of each of the outer guides tapers rearward away from the positioning slot as they extend upward. A top portion of a rear surface of each of the inner guides tapers forward toward the positioning slot as they extend upward.

Positioning features for electrical contacts of a replaceable unit of an electrophotographic image forming device

A replaceable unit for an electrophotographic image forming device according to one embodiment includes a pocket formed on a first side of a housing. A bottom end of the pocket is open for receiving an electrical connector during insertion of the replaceable unit into the image forming device. An electrical contact is positioned within the pocket and is electrically connected to processing circuitry on the housing. An outer guide is positioned on the first side of the housing and below the pocket. A portion of the outer guide inclines inward toward the first side of the housing as the outer guide extends upward. An inner guide is positioned within the pocket on a first inner surface of the pocket, which faces toward the first side of the housing. A portion of the inner guide inclines inward toward the first side of the housing as the inner guide extends upward.

A door assembly movably positioned to a body of an image forming device. The door assembly includes a first frame and a second frame. The first frame is movably attached to the body, and the second frame is movably attached to the first frame. The movable connections between the frames and the main body cause accurate locating of a photoconductive member mounted on the door assembly within the body. In one embodiment, a contour surface within the body contacts the second frame to locate the second frame within the body. Methods of moving the door assembly are also disclosed including moving the door assembly from an open orientation that is spaced from the body, to a closed orientation that is in proximity to the body. The movement of the door assembly causes interaction between the frames and the body to accurately locate the second frame.

The invention relates to an ink cartridge body which is removably mountable in a printer carriage area of an ink jet printer and an alignment and latching mechanism for the ink cartridge body. The printer carriage area includes at least first and second spaced-apart elongate guide rails and the ink cartridge body includes a printhead and at least two bearing points at predetermined locations on the ink cartridge body, each of the bearing points disposed on the cartridge body for separately engaging at least one of the elongate guide rails for aligning and maintaining the printhead in a predetermined orientation relative to the print media in the printer. The invention substantially reduces the number of parts and tolerances thereof required for aligning a printhead relative to a print media by directly aligning the cartridge body rather than the carrier in the carriage area of the printer.

Ink cartridge body and carrier assembly

The printhead unit is for an imaging apparatus having a guide member. The printhead unit is configured to be positioned in a carrier assembly within the imaging apparatus and is configured for movement within the imaging apparatus via the carrier assembly. The printhead unit includes a housing a printhead and at least one bearing. The housing has at least a first side member. The printhead is attached at least to the first side member of the housing. Further, the at least one bearing has at least one bearing surface, the at least one bearing being coupled to the first side member of the housing and positioned to engage the guide member.
