Positional Control Features of a Replaceable Unit for an Electrophotographic Image Forming Device

摘要

A replaceable unit for an electrophotographic image forming device according to one example embodiment includes an elongated body extending along a lengthwise dimension between a front and a rear of the body. The body has a reservoir for holding toner. The body includes an extension downward from the bottom of the body near the rear of the body. The extension has a downward chute formed therein in fluid communication with the reservoir. A rear face of the extension is unobstructed to receive a bias force in a forward direction toward the front of the body along the lengthwise dimension. An outlet port on the bottom of the extension is in fluid communication with the chute for transferring toner out of the reservoir. The replaceable unit may include a positioning bump on the bottom of the body at a rearmost position on the bottom of the body.

主权项

1. A replaceable unit for an electrophotographic image forming device, comprising:
an elongated body extending along a lengthwise dimension between a front and a rear of the body, the body further including a first side, a second side, a top and a bottom, the body having a reservoir for holding toner; a drive element on the rear of the body unobstructed to receive rotational power when the replaceable unit is installed in the image forming device; an electrical contact on the rear of the body unobstructed to contact a corresponding electrical contact when the replaceable unit is installed in the image forming device; an extension downward from the bottom of the body near the rear of the body, the extension having a downward chute formed therein in fluid communication with the reservoir, a rear face of the extension unobstructed to receive a bias force in a forward direction toward the front of the body along the lengthwise dimension; an outlet port on the bottom of the extension in fluid communication with the chute for transferring toner out of the reservoir; and a latch catch on the first side of the body positioned to receive a corresponding latch when the replaceable unit is installed in the image forming device to restrain the body from moving in the forward direction along the lengthwise dimension.
