Folding Horizontal Skew Adjustment (For B804 only)
• The fold unit is adjusted for optimum performance before the finisher is shipped from the factory. Do
this adjustment only if the edges of folded booklets are not even.
1. Switch the copier on and enter the SP mode.
2. Europe, Asia: Use SP6-134-001 (this is for A3 paper). North America: Use SP6-134-005 (this is for
DLT paper).
• If the original setting of SP6-134-001 or -005 is not "0", then you must do the vertical skew
adjustment (* "Fold Vertical Skew Adjustment") after you finish this horizontal skew procedure.
3. Use the 10-key pad to input "-2" (mm) for the SP value. (Press to enter the minus sign.)
4. Press [#] then exit the SP mode.
5. Open the front door and pull the stapler unit [A] out of the finisher.
6. Open the guide plate [B].
7. Loosen the adjustment screw [C] and then tighten until it stops. (Do not over tighten.)
8. Remove the lock screw [D].
9. Raise the tip [E] of the adjustment screw very slightly and allow it to descend under its own weight.

15. Open the front door of the finisher and pull the stapler unit [H] out.
16. Open the guide plate [I].
17. Turn the adjustment screw [J] to correct the amount of skew you measured from the test sheet.
• For + skew [F], turn the adjustment screw (clockwise).
• For – skew [G], turn the adjustment screw to the left (counter-clockwise).
• Every click in the +/– direction adjusts the fold position by 0.1 mm by moving the bottom fence
[K].
18. Raise the tip of the adjustment screw [J] and allow it to lower under its own weight.
19. Attach and tighten the lock screw [L].
20. Push the stapler unit into the machine, close the front door, then turn the copier on.
21. Europe, Asia: Do SP6-134-001 (this is for A3 paper). North America: Do SP6-134-005 (this is for
DLT paper).
22. Reset it to "0".
23. Do the test again.
24. If the result is satisfactory, this completes the adjustment. -or- If some skew remains, repeat this adjustment.
• After doing this adjustment, adjust for vertical skew, if necessary. (* "Fold Vertical Skew Adjustment")
Fold Vertical Skew Adjustment (For B804 only)
• The fold unit is adjusted for optimum performance before the finisher is shipped from the factory. Do
this adjustment only if the edges of folded booklets are not even.
