No. : ARE-163
1. Measure carried out to prevent problems of bad connections between the FFC
harness and the CCD PWB.
1.Model Name: AR-280/285/335/405
2.General: There was a possibility of bad connections of the FFC harness which is connected from
the CCD unit to the ICU PWB. As a measure to alleviate this problem, the action
described below has been carried out.
3.Cause: There was a possibility of bad connections occurring due to the vibrations which occur
when the FFC harness came in contact with the HDD. The vibrations were caused by
operation deviance due to the extreme length of the FFC harness.
4.Measure: A change has been carried out in the length of the FFC harness. The FFC harness has
been shortened by 30 mm as a measure to prevent contact between the FFC harness
and the HDD.
5.Action: From the 1st lot of 1999 March production.
2. Measure carried out to alleviate problems of contact between the ICU PWB and the
sub PWB guide.
1.Model Name: AR-405
2.General: There was a section of the gap between the ICU PWB and the ICU sub PWB guide R in
which there was very little margin of error. As a measure to alleviate this problem, the
attachment of a mylar sheet has been carried out to insure that contact is not made.

3.Action: From the 1st lot of 1999 March production.
3. Permanent measure carried out to alleviate problems of improperly tightened fixing
screws of the main motor.
1.Model Name: AR-280/285/335/405
2.General: There was a possibility of 1 of the 4 fixing screws of the main motor being improperly
tightened. As a measure to alleviate this problem, a change that was carried out in the
length of the fixing screws and the addition of a washer that was carried out were
reported in T/R No. ARE-142. As a permanent measure to alleviate this problem,
however, a change has been carried out in the thickness of the metal plate in the
location where there was a possibility of improper tightening of the fixing screw. The
thickness of the metal plate has been decreased. The fixing screw has been changed
once again, and is now the original size of 4 × 8. In addition to this change, the washer
has now been discontinued.
3.Action: *1 AR-S400/405: From the 1st lot of 1999 March production.
Japanese domestic production except for the models listed above:
Running change carried out from 1999 mid-February production.
Chinese (SOCC) production except for the models listed above:
From the 1st lot of 1999 April production.

4. Measure carried out to decrease the amount of abnormal noise in the ADU unit.
1.Model Name: AR-285/335/405 (only for machines bound for the 200 V series market destinations.)
2.General: There was a problem of abnormal noise which was occurring during ADU operations.
As a measure to alleviate this problem, the action described below has been carried out.
3.Cause: There was a problem of looseness in the reversion roller shown in the figure below,
which caused the abnormal noise to occur during operations.
4.Measure: The addition of a plastic slider on the F and R sides of the reversion roller has been
carried out as a measure to eliminate the looseness of the reversion roller.
Added plastic sliders
5.Action: AR-405: From 1999 mid-February production.
For all models except the model listed above:
From the 1st lot of 1999 March production.
5. Change in the shape of the ICU cover carried out in accordance with a change that
was carried out in the attachment locations of some of the parts in the ICU PWB.
1.Model Name: AR-405
2.General: A change was carried out in the attachment locations of some of the parts in the ICU
PWB. Some of the parts which had been attached to the rear side of the ICU PWB
have now been attached to the front side of the ICU PWB, and as a result of this
change, there was a problem of obstruction of the ICU cover. As a measure to alleviate
this problem, a change has been carried out in the shape of the ICU cover.
The cut-away portion
has been enlarged.
3.Action: From the 1st lot of 1999 March production.
