Troubleshooting
Printhead Failures
Random colored patterns on image
• Ribbon wrinkling. Reduce take-up torque. Check printhead pressure. Contact Zebra
Customer Service.
• Too much heat being applied to YMC panels. Try reducing gain, offset and preheat
separately for each color in the driver Device Settings > Color Calibration; “Color
Calibration” on page 59. 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. Contact Zebra Customer Service.
Random colored lines
• Probably resulting from excessive take-up torque. Contact Zebra Customer Service.
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. Contact Zebra Customer Service.
• Card hopper base set too low. Contact Zebra Customer Service.
