Malfunction: Possible cause Remedy
The press does not turn.
The claw is probably
defective .

The fault symbol

”Changeover from perfecting
to straight printing”
appears in the display
”Sheet-size adjustment”.

Change over to straight
printing again. The press is
again ready to run in
straight printing mode.
If the claw is not defective,
repeat the changeover or
sheet-length change.
