2. MEASURE TO ALLEVIATE PROBLEMS OF SOILED COPY PAPER
EDGES.
1. Measure to alleviate problems of Z-folding during copy operations carried out on
small sized original ducuments.
1.Model Name: AR-5132
2.General: There have been problems of Z-folds sometimes occurring during production when
small sized original documents (sizes such as A5, invoice, etc.) were transported through
the machine during feeding operations. The problems of Z-folds were caused due to the
fact that the paper feed drive load was light, causing the paper feeding speed to
increase. As a measure to alleviate this problem, the action described below has been
carried out.
No. : ARE-054
3.Description: When the paper feeding speed is detected as having overshot the paper feeding speed
control during paper feeding movement (with the exception of preparatory feeding), the
electrical power being supplied to the paper feeding motor is momentarily cut, causing
the paper feeding speed to decrease slightly. To achieve these ends, a change has been
carried out in the EP ROM of the PBA control PWB. In accordance with the change
described above, a change has been carried out in the part codes for the EP ROM and
the PBA control PWB.
From 1997 mid-August production, action concerning this problem has been carried out
in the production operations. Checks are being carried out on all machines produced,
and therefore there is no particular problem with the old PWBs or the old ROMs.
Furthermore, even if a machine is equipped with an old PWB, the replacement of the
ROM will be sufficient to change the old PWB into the equivalent of a new PWB.
4.Action: From 1997 mid-August production.

2. Measure to alleviate problems of soiled copy paper edges.
1.Model Name: AR-5132 (only machines bound for 200V destinations).
2.General: There has been some trouble with soiling of copy paper edges during double-side copy
operations. This problem was caused by the toner which had become adhered to the TC
guide in the TC unit. As a measure to alleviate this problem, the action described below
has been carried out.
3.Description: (1) A change has been carried out in the Teflon tape attached to the TC guide.
In addition to this change, the addition of a TC drum spacer has been carried out to
maintain a gap between the TC guide and the drum.

(2) The total transfer current has been raised by approximately 20µA. This change has
been carried out to standardize the current with the drum current.
Note: In accordance with the action described in (1) above, a change has been carried
out in the part code of the TC unit.
4.Action: From 1997 mid-April production. (Temporary action has been carried out from the 1st lot
of mass production until mid-April production.)
