2. Measure to alleviate problems of Z-folding during copy operations carried out on
small sized original ducuments.

1.Model Name: SF-A17/A56/A18/A57

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.

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: Running change from 1997 mid-August production.
