6.2 Preventive maintenance
Our machines are designed in such way that they need little (preventive) maintenance in addition to
the cleaning.
The following checks have to be performed:

Auto-grip shafts with blocking cords.
6.2.1 Auto-grip shafts
Check the auto-grip mechanism on each shaft.

The distance (d) between the rubber cords and the edges of the recess should be 8 ± 2.5 mm
(5/16 ± 3/32 in) minimum (the cord must not touch the skew).
Figure 19: Auto-grip shaft
If not, correct as follows:

Loosen the clamp (2) with the screw (1) until the cord is free on one side,

Shorten the cord by approximately 10 mm (0.4 in.),

Put the end of the cord back underneath the clamp (2),

Secure it by tightening the screw (1).
6.3 Troubleshooting
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 20: Wrinkles due to high pressure.

Decrease the roller pressure a little (5-10%).
