10. Close and lock the window.
11. Turn on the printer.
12. Reload the roll.
13. 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.
14. If you find that you have print-quality problems after a jam, try realigning the printheads. See
Align the printheads on page 9.
Avoiding substrate jams
Substrate jams may be caused by loading the substrate with too much skew: do not ignore the warning
message that appears during the loading process 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
2
O for banners, 35 mmH
2
O for vinyl, and 50
mmH
2
O 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 select the
icon, then Substrate handling options > Extra
bottom margin. Set the margin to 100 mm. If that is not enough, try 150 or 200 mm. This
extra margin will apply only to jobs that start printing when the printer is idle and when the cutter
is disabled.
●
Increase the vacuum level in steps of 10 mmH

O. Do not exceed the following limits: 20 mmH

●
Decrease the warm-up drying temperature in steps of 5°C.
●
Decrease the warm-up curing temperature in steps of 5°C.
●
Increase the number of passes.
●
Make sure that the substrate is stored in the same room in which the printer is located.
The substrate is deformed or wrinkled
If your substrate is deformed or wrinkled by the drying and curing process, change the temperature
settings before printing the next job, and advance the substrate, using the Move Substrate key on the
front panel, 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 select the
icon, then Substrate handling options > Extra
bottom margin. Set the margin to 100 mm. If that is not enough, try 150 or 200 mm. This
extra margin will apply only to jobs that start printing when the printer is idle and when the cutter
is disabled.
