Troubleshoot substrate 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 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 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 mmH2O. Do not exceed the following limits: 20 mmH2O for banners, 35 mmH2O for vinyl, and 50 mmH2O for other substrate families. ● 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.
