There are a number of things that can lead to a drop in print quality. To avoid them, Evolis recommends checking the card surface. Dirty cards can adversely affect quality. You should carry out printer cleaning the Primacy after 1,000 cards. A warning light will flash at this point and it’s important to carry out the clean: any more than 1,200 cards printed between routine cleaning cycles will invalidate the warranty.
If white lines are appearing on your cards, it may be due to a dirty print head. If your cards are printing blurred, check the ribbon is in the correct position, the printer is clean and you are using compatible cards.
