2.8.4 PAPER REGISTRATION
Overview
The registration sensor [A] is positioned just before the registration rollers [B].
When the paper leading edge activates the registration sensor, the registration motor
is off and the registration rollers are not turning. However, the upper relay roller (or
LCT relay roller for feed from the LCT) [C] stays on for a bit longer.
This delay allows time for the paper to press against the registration rollers and buckle
slightly to correct skew. Next, the registration motor energizes and the upper relay
clutch re-energizes at the proper time to align the paper with the image on the drum.
The registration and relay rollers feed the paper to the image transfer section.
The registration sensor is also used for paper misfeed detection, and the LCT relay
sensor [E] detects jams at the LCT roller.
