Only the differences from the base copier are described in the
following pages. Therefore, this documentation should be treated
as an insert version of the base copier’s service manual. It should
always be utilized together with the base copier’s service manual.

INSERTION PROCEDURE OF SERVICE MANUAL
1. Replace the book spine tag with the new one.
2. Insert the A220 service manual after the A175/A176/A177/A191/A192
manual.

6. PAPER FEED
6.1 OVERVIEW
This model has two or three drawer tray paper feed stations.
The following table shows the configuration of each feed stations of the
copiers.
Feed station A220 - 10, 17, 20, 29
three tray copiers A220 - 22 two tray copiers
1st 550 sheets tray 550 sheets tray
2nd 550 sheets universal tray 550 sheets universal tray
3rd 550 sheets tray storage tray
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.

6.8 PAPER LIFT MECHANISM
When the tray is set in the machine, the machine detects this condition by
using several detection methods as shown in the table:
Feed station
1st Tray set switch
2nd Paper size switch
3rd Tray set switch (not used for storage tray version)
When the machine detects that the paper tray is set in the machine, the lift
motor [A] rotates and the coupling gear [B] on the tray lift motor engages the
pin [C] of the lift arm shaft [D], then turns the tray lift arm [E] to lift the tray
bottom plate [F].

CAUTION
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.
NOTE: There are neither 1,500-sheet LCT or 4th feed station versions.

SERVICE TABLES

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 recur after several
copies.
1.12 OTHERS
1. This machine has re-manufactured parts, which are selected from
dis-assembled machines in the Japanese domestic field. Note that there
are old and new parts in the machine.
