ADJ 1
Paper alignment width
adjustment
This adjustment is executed when a trouble occurs in paper align-
ment.
1) Execute Sim3-10.
2) Select "1: FPAM ADJUST".

3) Enter the set value with 10-key. (Press [C] key to clear the
entered values.)
Initial value: 50
When the adjustment value is increased by 1, the alignment
plate F/R width is narrowed by 0.419mm in alignment opera-
tion.
When the adjustment value is decreased by 1, the alignment
plate F/R width is widened by 0.419mm in alignment operation.
The alignment plate F and the alignment plate R cannot be
adjusted separately. The shift amount on the F side and that
on the R side are alternatively corrected everytime the adjust-
ment value is increased by 1. (Correction with 51 for the F
side, and 52 for the R side. ... 59 for the F aide, and 60 for the
R side. Similar when the set value is decreased.) When, how-
ever, the alignment plate lower cannot be adjusted due to the
mechanism structure, adjust only on the R side without cor-
recting both of the F and the R side.
4) Press [OK] key to save the set value.
5) After completion of the adjustment, make staple copies.
