PAPER FEED

6.11.7 SIDE FENCES

[A]
If the tray is full of paper and it is
pushed in strongly, the fences may
deform or bend. This may cause the
paper to skew or the side-to-side
registration to be incorrect. To correct
this, each side fence has a stopper [A]
attached to it. Each side fence can be
secured with a screw, for customers
who do not want to change the paper
size.

6.11.8 PAPER REGISTRATION
[A]
The drive from the main motor [A] is
transmitted to the registration roller
through the registration clutch gear [B].
[B]
The registration sensor [C] is used for
correcting paper skew and for
detecting paper misfeeds.
[D]
The cleaning mylar [D] contacts the
registration roller. It removes paper
dust from the registration roller so that
this dust will not transfer into the
development unit through the drum-
[C]
cleaning unit.
The amount of paper buckle at the
registration roller to correct skew can
B121D961.WMF
be adjusted with SP1-003.
If jams frequently occur after
registration, SP1-903 can be used to activate the relay clutch so that the relay roller
assists the registration roller in feeding the paper along. When feeding from the by-
pass tray, the by-pass feed clutch is activated, turning the by-pass feed roller. This
feature may be needed when feeding thick paper, and cannot be used for the first
paper feed tray.
