1.4.5 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.
