(How to align)

When the binder’s creep is out of the specification, align it to be within the specification by
[fine tuning Saddle stitch location/fold location].

Tune each paper size with the code of the adjustment mode (05) in the machine.
For procedure, refer to the Service Manual (Service Handbook).

If the upper side of the actual output paper is longer (A), the value is increased.
If the upper side is shorter (B), the value is decreased.
Change of "1" value moves the fold location approx. 0.25mm.
