7. Lower the substrate pinch lever. 8. Make sure that there are no pieces of substrate left in the printer. In particular, check in and under the curing module, and in the substrate path. 9. Close the window. 10. Turn on the printer. 11. Reload the roll. 12. If some substrate continues to cause an obstruction within the printer, it can often be cleared by loading a rigid substrate type into the printer. 13. If you find that you have print-quality problems after a jam, try realigning the printheads. See Align the printheads on page 127. Avoiding substrate jams while printing Substrate jams may be caused by loading the substrate with too much skew: do not ignore the warning message that appears during the loading procedure in this case. They may also be caused by not enough vacuum suction in the printing zone. If you decide to increase the suction, do not exceed the following limits: 20 mmH2O for banners, 35 mmH2O for vinyl, and 50 mmH2O for other substrate families. If you experience jams only at the beginning of a print, try the following suggestions. ● Disable the automatic cutter. ● Go to the front panel and press , then Substrate handling options > Extra bottom margin and Extra top margin. Set both margins to 100 mm. If that is not enough, try higher values. ● Increase the vacuum level in steps of 10 mmH2O. Do not exceed the following limits: 20 mmH2O for banners, 45 mmH2O for vinyl, and 60 mmH2O for other substrate families. Consider reducing the vacuum percentage at the front of the print zone for thin substrates. ● Increase the number of passes. ● Make sure that the substrate is stored in the same room in which the printer is located. ● Try using the substrate edge holders.

Avoiding substrate jams while printing
Substrate jams may be caused by loading the substrate with too much skew: do not ignore the warning
message that appears during the loading procedure in this case.
They may also be caused by not enough vacuum suction in the printing zone. If you decide to increase the
suction, do not exceed the following limits: 20 mmH

other substrate families.
If you experience jams only at the beginning of a print, try the following suggestions.
●
Disable the automatic cutter.
●
Go to the front panel and press

Consider reducing the vacuum percentage at the front of the print zone for thin substrates.

Make sure that the substrate is stored in the same room in which the printer is located.
●
Try using the substrate edge holders.
The substrate is deformed or wrinkled
If your substrate is deformed or wrinkled by the curing process, change the temperature settings before
printing the next job, and advance the substrate, using the
Move substrate
option in the front panel's
Substrate
menu, so that the next job will be printed on undamaged substrate.
If the problem appears only at the beginning of the print, try the following suggestions.
●
Disable the automatic cutter.
●
Go to the front panel and press
