I have one or multiple horizontal white lines on my printed cards. What can I do?

White lines on the printed cards mean that the print head is unable to heat the ribbon in this zone: the ink cannot be diffused/applied correctly onto the card surface. This issue may arise from a dirty or faulty print head.
If cleaning of the print head does not clear this defect, please contact your Evolis reseller/distributor.
