Missing portions of the print
• The ribbon has excess slack.
• The ribbon is bent or folded.
• The ribbon path at the print head is too high or too low.
• The ribbon is twisted.
Action:
1. Reinstall or replace the Ribbon Cartridge.
2. The ribbon could bind, bend or reverse if the Card Guide Assy is not adjusted correctly. Perform the Card Guide
Mount Position Adjustment.
3. Ribbon slack commonly occurs when the platen gap is too narrow, for example if the paper or form being printed
is too thick. Make sure the paper is within specifications. If overlapping forms are being used, be sure the
SelecType setting for Overlapping Multipart Forms is set to “On”.
4. Use SelecType to change the Platen Gap settings.
NOTE: The following adjustments affect the platen gap: the Card Guide Mount Position Adjustment, the
APTC Thickness Detection Adjustment, and the APTC Detection Adjustment.
5. A portion of the ribbon might have become twisted. Check the ribbon for a twist. Replace the Ribbon Cartridge
if necessary.
