9. THE MOST COMMON FAULTS (TROUBLESHOOTING)
1) Crinkled paper
-
The paper gets crinkled, especially paper of lower paper grammage, because there is too much
thrust of the feeding system on paper during feeding into the machine fig. 32 and fig. 33.
Troubleshoot in following steps:
a) Insert processed paper under the callipers.
b) Decrease the feeding table thrust using the table thrust regulation screw (14).
