Troubleshooting
Error messages
Most of the problems described in the following pages are correctable by the user, but please
note there is the potential for unexpected results if the procedures are not followed carefully. If
in doubt, call for service assistance.
Before calling for technician help, do the following:
• Check all cable connections, including power.
• Check that the power switch is ON.
• Unless you hear noises suggesting a card jam condition, try power
cycling: switch OFF, wait 15 seconds, then switch ON.
• Open the main cover, then look for obvious problems, such as a
card where it shouldn’t be, media outages or misfeeds (color rib-
bon, laminate, cleaning cassette).
• Check this section, referring if necessary to the relevant Tech Note.
