Abstract

A copy substrate registration mechanism registers substrates before they contact the photoreceptor belt where image transfer takes place. Center registration machines require variable top-edge sensor locations based on the various substrate widths that are being run. To handle the smaller substrates, the nips must be closer to the Transfer area. This invention addresses the problem of placing the top edge sensor at the appropriate location for the substrate width being run including smaller substrate sizes.

Translating Top Edge Sensor for substrate registration mechanism

A copy substrate registration mechanism registers substrates before they contact the photoreceptor belt where image transfer takes place. Center registration machines require variable top-edge sensor locations based on the various substrate widths that are being run. To handle the smaller substrates, the nips must be closer to the Transfer area. This invention addresses the problem of placing the top edge sensor at the appropriate location for the substrate width being run including smaller substrate sizes.

The top–edge sensor can be placed at the appropriate location, for the substrate width being run, by mounting it to a translating mechanism, such as a gear rack or timing belt, and controlling the mechanism, to position the sensor, with a stepper motor controlled by firmware. Machine application software will download to firmware the substrate width / location required.
