Gaps in image at edges and corners
• Possible de-lamination/wear of platen’s rubber surface. Try cleaning platen; see
“Platen Care and Cleaning” on page 82. If unsuccessful, replace platen; contact Zebra
Customer Service.
• Possible non-uniformity of card thickness, or card surface defects.
Continuous white or black stripes on card’s longer dimension
• Before doing anything else, clean the printing edge of the printhead with alcohol; see
“Printhead Cleaning” on page 81.
• White stripe means blown pixel (non-functioning heating element). One or two blown
pixels in isolation may be acceptable to some. Otherwise replace printhead; contact
Zebra Customer Service.
• Black stripe means non-functioning circuit(s) on printhead. If so, replace printhead,
but first check that it is not the result of an image size change not followed by power
cycling the printer; contact Zebra Customer Service.
