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
•
Black stripe means non-functioning
circuit(s) on printhead. If so, replace
printhead, Reference
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
•
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.
