Troubleshooting guide

Random colored patterns on image
• Ribbon wrinkling. Reduce takeup torque. Check print-
head pressure. TN4
• Too much heat being applied to YMC panels. Try reduc-
ing gain,offset and preheat separately for each color in
the driver Device Settings > Color Calibration, TN4-5.
Typically, the set of values should be the same for each
color.
• Printhead running too hot. Can happen after head
replacement if head resistance incorrectly entered
through printer driver.

Image not centered on card
• Properties > Device Settings > Printer Adjustment >
Horizontal/Vertical Offset.
Image offset on card
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. TN4
• 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
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.
Consistent image defects, card after card
• Debris on platen, or platen surface not flat. Clean platen,
or replace if necessary.
TN2
Debris on platen
This gross image artifact was caused
by a tiny scrap of card less than 0.01"
(0.25 mm) thick.
Scratches/dings on long edges of card
Look for a narrow band of abrasion up to about 0.1" (2.5
mm) in from either or both of the long edges.
• Card hopper base set too low. TN2
Laminate not centered on card
• Vertical offset adjust (mechanical adjustment). TN6
• Horizontal offset: Properties > Device Settings > Printer
Adjustment > Laminate Station Adjust.
TN6
Laminate offset
Laminate not parallel with card edges
• Skew adjust (mechanical adjustment). TN6
• If using partial width laminate, edge guide not properly
installed (one of two positons). Section 2
• Transfer guide not properly installed. Section 2
• Laminate patch wrapped around heated roller. Page 3-3
Laminate wrinkling
• Can occur at end of roll. Remove cassette. If nearly out,
discard. Install fresh roll.
• If not end-of-roll problem, suspect obstructions in
laminate feed path.
Random colored lines
Probably resulting from
excessive takeup torque.
