Laminator spot check
Note • Remember, the P640i Printer includes upper and lower laminators; the P630i Printer
has the upper laminator only.
• Make sure the transfer roller toggle is in the operating position, pointing to the right.
• Upper or lower laminate feed problems: remove, then replace transfer guides,
discarding laminate patches on transfer rollers. Check for laminate where it shouldn’t
be. Remove both laminate cassettes. If out, or nearly out, load fresh laminate. Wind
laminate back in to eliminate overhang. Reinstall cassettes, latching securely. Visually
check path from cassette(s) through feed roller, cutter and transfer guide.
• Check for misfeeding of laminate due to poor engagement of white plastic idler on
cassette with drive roller. Mark the upper core to check that it rotates (no need to mark
the lower core - watch the notches on the laminate core). Feed laminate by pressing
the LAMINATE button.
• Laminate patch may be wrapped around the heated roller, causing card feed problems
and/or poor lamination. Turn printer OFF, allow 10 minutes for cooling, then remove
heated rollers - careful, they will still be HOT. Remove the rogue patch. Do NOT use
a metal knife or any tool that might damage the heated rollers.
• Check upper and lower laminate sensor readings, with and without laminate present
(< 20 if present, > 180 if absent - numbers valid only if transfer guides installed).
Quality Problems
Important • Operator should contact Zebra Card Printer Solutions Customer Service before
changing any factory settings within the printer.
Poor color registration
• Minor mis-registration of Y, M and C color passes may be due to printhead angle
adjust screw not in firm contact with printhead frame.
• For gross mis-registration of Y, M and C, suspect that the card not firmly positioned
against left hand pick edge of truck on one or more passes. Spring at left end of platen
may be missing or bound up.
• Check printed card for damage on corners or edges. Example: the card may be
scraping along the underside of the hopper base molding.
• Printhead pressure too light.
• Printhead may be running hot. Will occur if head resistance incorrectly entered in
driver software.
• Toothed transport belt pulley may be slipping on drive shaft. Tighten set screws (make
sure the screws bear on flats on the shafts).
