2.8.7 PAPER REGISTRATION

Overview
[A]

A229D595.WMF
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 relay clutch [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. Then, the registration motor
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.
