6.11.6 PAPER REGISTRATION

[B]
The registration drive roller [A] and idle roller [B] correct the skew of the paper to
ensure that the leading edge of the paper is positioned correctly at the drum. The
paper feed/development motor [C] drives the registration mechanism.
The registration sensor [D] is positioned just before the registration rollers. When
the leading edge activates the registration sensor, the registration clutch is
switched off and the registration rollers stop turning. However, the relay clutch [E]
remains on slightly longer. This delay allows more time for the paper to press
against the registration rollers and buckle slightly to correct any skew. The
registration sensor also detects misfeeds.
Next, the registration clutch [F] actuates and the relay clutch at the correct time to
align the paper with the image on the drum. The registration rollers then feed the
paper to the image transfer section.
Two new dust blades have been added around the registration roller. The idle roller
dust blade [G] cleans the registration idle roller. This dust blade has a small dust
box that collects paper dust that must be emptied periodically.
The registration roller dust blade [H] cleans the registration roller. For details about
how to remove and clean these new parts, see Section "3 Replacement and
Adjustment".
