Toner cartridge for an image forming device having a retainer assembly having positioning features for processing circuitry

摘要

A replaceable unit for an electrophotographic image forming device according to one embodiment includes a housing having an internal toner reservoir. A circuit board is mounted within a pocket on an exterior of the housing. An outer ramp is positioned outside the pocket and ahead of the pocket with respect to a direction of insertion of the replaceable unit into the image forming device. The outer ramp is angled to direct the electrical connector of the image forming device toward a plane of the circuit board during insertion of the replaceable unit into the image forming device. An inner ramp inside the pocket is angled to direct the electrical connector of the image forming device toward the plane of the circuit board during insertion of the replaceable unit into the image forming device.
