Paper can also be fed using the by-pass feed table which has an
independent feed mechanism. The by-pass feed table can hold 50 sheets of
paper.

All feed stations use an FRR feed system. Rotation of the pick-up roller [A]
drives the top sheets of paper from each tray to the feed [B] and the
separation [C] rollers. The feed and separation rollers then take over paper
drive. If more than one sheet is fed by the pick-up roller, the separation rollers
rotates in the opposite direction and prevents all but the top sheet from
passing through to the registration rollers.

When installing the copier, make sure that the copier is unplugged.

NOTE: Insert the leveling shoes [A] under the leveling feet [B] for the front

side, and level the machine before starting the installation. (The
leveling feet [B] can be screwed up or down.) Extra leveling shoes
(AH013008) and leveling feet (AH011004) are available as spare
parts.

1. Remove the tape strips.

SERVICE REMARKS

1. SERVICE REMARKS

1.11 FUSING UNIT

The following remark is not written in the A175/A176/A177/A191/A192
service manual.
However, this remark has been added as a A175/A176/A177/A191/A192
copiers service remark by RTB.

5. Silicon oil may slightly soak into the surface of the hot roller during

machine storage. The silicon oil may stick to the surface of the pressure
roller when the hot roller was in contact with the pressure roller at
installation. The pressure roller may slip due to the oil because the hot
and pressure rollers are new. Therefore, the smeared image may appear
on the leading edge at about 10 mm on the 1st copy. This is because the
hot roller is rubbing the leading edge of the copy on the pressure roller.
This symptom occurs only at the 1st copy after installation. Make sample
copies and make sure that the symptom does not recu r aft er several
copies.
