BUFFER ROLLER ASSEMBLY
ALIGNMENT FAULTS (DURING WRAPPING ON BUFFER ROLLER)
An alignment fault can occur during staple sorting if the degree of wrapping of paper on the buffer
roller is not appropriate, and the problem can be corrected by providing the measures shown herein
during servcing wor k.
<Symptom>
An alignment fault can occur in sheets delivered after stapling by the sorter.
<Cause>
If the degree of wrapping of paper on the buffer roller is not appropriate, the resulting displacement of
sheets will lead to misalignment during stapling operation.

< Making Checks and Maki ng Adjustments >
1. Turn off the power, and set the DIP switch
(SW103) on the finisher controller PCB as
shown in Figure 1.
2. Set the copier so that the copy count is '2' and
sort mode is selected; then, place three originals.
3. Press the Copy Start key.
•
The copier starts to operate and stops as soon as
sheet wrap a ro und the buff e r r o lle r.

6. Turn off the power, and set the DI P switch (SW103)
on the finisher controller PCB as shown in Figure 3.
7. Turn on the po wer, and press t he push switch
(SW104) on he finisher controller.
•
LED101 will indic ate the present setting.
8. As necessar y, press the push switch (SW105 or
SW106) on the finisher controller PCB. ( See Figure
4.)
•
Each press o n S W105 increa ses the degree of
wrapping by 1.74 m m.
•
Each press o n S W106 decrea s e s t he degree o f
wrapping by 1.74 m m.
9. Press the push switch ( S W104) on the finisher
controller PCB.
