Main motor rotation is transmitted to the registration clutch [A] (located on the
lower registration roller shaft) through the relay gears [B].
The registration sensor [C] is positioned just before the registration rollers.
When the paper's leading edge activates the registration sensor, the
registration clutch turns off and the registration rollers stop turning. However,
the relay clutch stays on for a bit longer. This delay allows time for the paper
to press against the non-turning 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 towards the image transfer
section.
The registration sensor is also used to detect paper misfeed.
