Printhead Failures
White line across length of the card
• The white line is a sign of a blown pixel.
• The adjacent black stripe is a printhead driver problem (i.e., components on the
head itself).
• These are independent problems, not necessarily co-located, that may require
replacement of the printhead; contact Zebra Customer Service.
Random occurrences of white (unprinted) spots
• Possible card quality problem. Run IDPrint Lite with graytone.bmp on cards from a
different batch. Check platen surface for specks of debris.
Image not centered on card
• See “Printer Adjustment” on page 58.
Image missing at top or bottom of card
• Ribbon folded over at edge. Slacken ribbon by pulling more out of supply roll, unfold
edge then press
RIBBON button to re-sync.
• Bottom edge and/or right hand edge of image missing could be card layout
application sending wrong image size (should be 952 x 578 pixels). Select appropriate
image size (if available) in Preferences, or modify layout application.
Image loss at top of card (on either edge)
• Almost certainly due to ribbon fold-over.
• Could be a head non-pivoting problem; contact Zebra Customer Service.
• Could be an image size problem.
Consistent image defects, card after card
• Debris on platen. Clean platen; see “Platen Care and Cleaning” on page 82.
• Platen surface not flat. Clean platen; see “Platen Care and Cleaning” on page 82.
Replace if necessary.
