ABSTRACT:
A laser printer includes a cover with a top surface and an adjoining wall having an inlet opening for single-fed sheets. A receptacle is positioned beneath the cover for receiving a toner supply and is positioned adjacent the adjoining wall. A toner loader door encloses the receptacle and includes a first portion which mates with the cover's top surface and a second portion that abuts the adjoining wall. The first and second portions meet at point of joinder to form an L-shape. The second portion of the toner loader door is pivotally mounted to the adjoining wall and enables the toner loader door to pivot between an open position and a closed position. A sheet feed mechanism is positioned adjacent the wall and feeds sheets through the inlet opening. The sheet feed mechanism is pivotally mounted to the printer by a spring biased pivot which forces the sheet feed mechanism against the toner loader door so as to maintain it in a closed position. The sheet feed mechanism is hand pivotable away from the wall to allow the cover to be pivoted to the open position, where the point of joinder and the sheet feed mechanism interact to maintain the toner loader door in the open position.
