•
Secure it by tightening the screw (1).
6.3 Trouble shooting
During processing wrinkles can show up in the image (1) on the in-feed table (2) and in the process
result (4) on the output table. The figures below show some examples where it is caused by the
main rollers (3) and gives a possible solution.
Wait until a few meters is processed to see results.
Pressure too high.
Figure 23: Wrinkles due to high pressure.
•
Decrease the roller pressure a little (5-10%).
Pressure too low.
