11.10 PAPER REGISTRATION
Main motor rotation is transmitted to the registration clutch [A] (located on
the lower registration roller shaft) through the timing belt [B] and the relay
gear [C].
The registration sensor [D] is positioned just before the registration rollers.
When the paper leading edge activates the registration sensor, the
registration clutch turns off and the registration rollers stop turning. After the
registration clutch turns off, the relay clutch [E] stays on for an extra 108 ms.
This delay allows time for the paper to press against the registration rollers
and buckle slightly to correct skew. The registration clutch energizes and the
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.
