Troubleshooting
Printhead Problems
4.8 Printhead Problems
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.
Random occurrences of white (un-printed) 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
• To adjust the horizontal/vertical offset, select Start > Printers and Faxes. Right click
on the Zebra P630i or Zebra P640i printer listing. Select Properties > Device Settings
> Printer Adjustment > Print Station Adjust...
Image offset on card
• Correct this by increasing horizontal (X) offset, decreasing vertical (Y) offset.
Image loss at top of card (on either edge)
• Almost certainly due to ribbon fold-over.
• Could be head non-pivoting problem. Contact Zebra Customer Service.
• Could be image size problem; resize image.
