ABSTRACT:
An image forming apparatus, such as a printer, may have a horizontally-loaded drawer containing, for example, a toner cartridge or an image forming unit having toner. The apparatus may have an opening through which the drawer is inserted, and a cover over the opening. The cover may include two or more protrusions to assist in forcing the drawer into place as the cover is closed. The cover may include a first protrusion that is closer to the cover's hinge, and a second that is farther from the hinge than the first. The first protrusion may also be longer, extending further from the cover, than the second, so that during the closing operation, the first protrusion makes contact with the drawer before the second. The points of contact on the drawer may be angled and/or curved such that the force exerted by the protrusions directs the drawer horizontally and, if desired, downwardly towards an operating position. A protrusion may be aligned such that, when the cover is in the closed position, the protrusion is offset from a point of contact on the drawer, and exerts no horizontal force on the drawer.
