980541-001 Rev. A P640i Card Printer User Guide 27
Unusual events
In all of the following cases, and all other unusual events, try power cycling first, then
investigate specific issues:
• Printhead descends before card arrives. Check horizontal offset. Reference Technical Note
4
• Printhead stays down after card has gone away. Check card presence sensor. Reference
Technical Note 2
• Laminate cutter(s) fails to operate. see below, and reference Technical Note 6
• Unusual media light indications.
Laminator spot check
• Make sure the transfer roller toggle is in the operating position, pointing 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, Reference Technical Note 6, with and
without laminate present (< 20 if present, > 180 if absent - numbers valid only if transfer
guides installed).

Guide.
Error messages
Most P640i error conditions are identified by the printer itself, and are reported by the
computer as error messages with corrective actions. Error messages are not further described
in this section of the manual, which deals only with fault conditions that are not reported
automatically. On this page are five examples of error messages:
There is almost no preventative maintenance to do. Dust and debris should be vacuumed out
every 12 months, or more frequently in adverse environments.
Important • Most problems can be prevented by careful handling of
the media (cards, color ribbon and laminate), see Section 2, Media
Handling.
