• Use the Image Position option within the Image Transfer tab of the printer driver as described
in Section 3.5.1 to precisely center the image.
• Make sure that the Platen Roller is clean. If unsure, follow the procedure for cleaning the Platen
Roller in Section 3.9.2.
• See Print Offset, Transfer Tension, Transfer TOF (Top of Form), and Transfer EOF (End
of Form) Alignment
in Section 7.3 to adjust the printer through the LCD.
• Verify that the Peel-Off Bar and the Ribbon Peel bar height is correct. From the front of the HDP
Card Printer, the Peel-Off Bar on the input side (see drawing 840159) should be flush with the
frame; the Ribbon Peel Bar on the output side should have a 3/16-in. (4.5mm) gap between the
frame and the Ribbon Peel Bar. To try and remedy the offset printing, raise the bar higher off of
the card 0.005 inches by loosening the screws for the Peel-Off Bar and carefully raising both sides
the same amount. The Peel-Off Bar assembly should be equidistant from the frame at both ends.
• Adjust the Ribbon Tension by +1 and print a sample card. If symptoms appear better, continue
adjusting until image placement is correct. If symptoms appear worse, adjust the Ribbon
Tension
by –1 and print a self-test. If this makes the image placement look better, continue
adjusting until image placement is correct.
• Verify Platen Roller Drive Belts. The small belt is tensioned by a spring and the large belt should
be tensioned by hand to approximately the same tension as the short belt.
2.9.10 Poor Image Quality
Symptom: Photos on the cards look pixilated or grainy.
Good Bad
• Use high-resolution, 24-bit color images. Always capture an image at a 24-bit color setting, at 300
dpi, and at the same size at which it will be printed on the card whether capturing with a scanner
or digital camera. If a small or low-resolution image is stretched or "blown up", a pixilated or
grainy effect will occur when printing.
2.9.11 Image Washout on Film
Symptom: Image appears to not be completely printed on Film.
• Verify that the upper and middle modules are seated properly and are completely locked down.
• Remove the Printhead and reinstall. If problem persists, replace the Printhead
• Printhead pressure may be too low. Check the Printhead path to ensure there are no obstructions
and that the springs and cam are in the proper location. The lobe of the cam should be in the up
position when not printing. See drawing 840160.
• Increase Image Darkness by increments of five as described in Section 7.3.21
• If printing with non-FARGO cards, try reprinting with FARGO cards.
