Care should be exercised to attach the ferrite core to the harness of the

interface connector (12 pin) of the ICU interface harness and the optical
main harness (indicated by the double arrow in the figure above).

3) The addition of a ferrite core has been carried out to the harness (on the BC side)
between the TC case unit and the high voltage PWB.

4) A change has been carried out in the position of the attached core of the interface
harness between the ICU and the PCU. The addition of a binding band has also been
carried out.

5) The addition of a binding band has been carried out to the grouped optical main
harness, ICU interface harness, and OP flat cable.

6) The addition of a ferrite core has been carried out to the inner harness of the optical
unit.

3.Action:

From 1997 March production.

2. Measure to improve safety performance.

1.Model Name:

AR5132 (Only for machines of the 200 V series)

2.General:

There was a possibility of the machine short circuiting if contact with the coil on the NF PWB
when attaching the rear cabinet while the power supply cord is plugged into an outlet. As a
measure to alleviate this danger, the addition of a protect sheet has been carried out. At the
same time, a change has also been carried out in the wire saddle. (Note: there has been no
change carried out in the part codes in accordance with these changes.)

3.Action:

From 1997 May production.

When carrying out service or
maintenance operations, care
should be exercised in following the
instructions described in the service
manual and the warning label, and
the AC cord should always be pulled
out of the electrical outlet before
commencing.

3. Measure to alleviate problems of jams in the ADU.

1.Model Name:

AR5132

2.General:

1) There is a possibility of jams occurring due to the DPPD2 actuator failing to
operate as a result of the angle of the copy paper flow. As a measure to alleviate this
problem a change in the angle of the DPPD2 actuator has been carried out with the
actuator sheet to facilitate operation of the DPPD2 actuator

2) The addition of a gasket has been carried out to reinforce the grounding between the
machine and the ADU during double side copy operations.

1) Method of attaching the actuator sheet

2) Paper transport P/G upper unit in the ADU

3.Action:

From the start of 1997 February production.

Caution 2: Move the paper transport P/G upper unit,

and attach so that the gasket and the ADU

frame Fare always in contact.

Caution 3: The gasket attachment standard

should be in contact with the shaft.
