Lexmark C790 - Lexmark Dot Matrix Manual

* 50–150 Sheffield is optimal. This printer may support labels with smoothness of less than 50 Sheffield such as coated paper,
polyester, vinyl, or other synthetic facestock paper. Using media higher than 200 Sheffield could result in print quality
degradation.
Card stock and label guidelines
Labels are one of the most difficult print materials for laser printers. A fuser equipped with a dry web cleaner may be
required for label applications to optimize feed reliability. If you print large quantities of labels or other glossy print
media, then install a dry web cleaner upgrade kit (P/N 40X1856). Contact your local service representative for ordering
information.
When printing on labels:
•
From the printer control panel, set Paper Type to Labels in the Paper Menu. For vinyl and other heavy labels, set
Labels Weight (under the Paper Weight menu) to Heavy, and set Labels Texture (under the Paper Texture menu)
to Smooth.
•
Do not load labels together with paper or transparencies in the same paper tray. Combining print materials can
cause feeding problems.
•
Use full label sheets. Partial sheets may cause labels to peel off during printing, resulting in a paper jam. Adhesive
material may contaminate your printer. It could also void your printer and cartridge warranties.
Print on sheets with more number of labels to improve registration.
When printing on card stock:
•
Set Paper Type to Card Stock in the Paper Menu.
•
Do not use creased card stock. It may cause paper jams.
