A train of gears transmits main motor [A] rotation to the registration clutch gear [B]
(located on the lower registration roller shaft).
The registration sensor [C] is positioned just before the registration rollers.
When the leading edge of the paper activates the registration sensor, the
registration clutch is off and the registration rollers are not turning. However, the
⇒
relay clutch [D] 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. Then, 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.
