Abstract

In a printer or copier, providing improved paper path sheet jam clearance by a paper path decision gate rotatably driven by a servo motor or stepper motor drive (instead of the usual solenoid drive providing only two gate positions). Thus, the paper path gate can be normally driven to, and held in [except when gating], a neutral or intermediate "home" position that will not press against a sheet caught or jammed in the gate area of the paper path. Schematically shown in the figure is one example, with a gate 10 rotatably driven by a servomotor "S" from a home position 12 into either an "up" gating position 14 or a "down" gating position 16, but normally held in a neutral position therebetween.
