Troubleshooting quality problems

Continuous white or black stripes on card’s longer dimension

White stripe means blown pixel (non- functioning heating element). One or two blown pixels in isolation may be acceptable to some. Otherwise replace printhead. Reference Technical Note 4

Black stripe means non-functioning circuit(s) on printhead. If so, replace printhead, Reference Technical Note 4, but first check that it is not the result of an image size change not followed by power cycling the printer.

These are independent problems, not necessarily co-located.

Random occurences 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.

White spots like these may be caused by card surface imperfections.

Image not centered on card

Properties > Device Settings > Printer Adjustment > Horizontal/Vertical Offset.

Correct this by increasing horizontal (X) offset, decreasing vertical (Y) offset.

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. Reference Technical Note 4

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.

Could be on either edge. Almost certainly due to ribbon fold-over, but could be a head non-pivoting problem, or an image size problem.
