Imaging unit having positioning features for electrical contacts for use in an electrophotographic image forming device

A replaceable imaging unit for an electrophotographic image forming device includes an electrical contact positioned within a pocket of an electrical connector of the imaging unit that has an opening facing toward the front of a housing of the imaging unit to permit a corresponding electrical connector of the image forming device to enter the pocket and contact the electrical contact when the replaceable imaging unit is installed in the image forming device. A guide wall on a first side of the housing is spaced toward the front of the housing from the opening of the pocket of the electrical connector. The guide wall is unobstructed to contact the corresponding electrical connector of the image forming device during insertion of the replaceable imaging unit into the image forming device for aligning the corresponding electrical connector of the image forming device along a vertical dimension of the housing.
