operation".
CD-R Guide error
[Occurrence Condition]
This error occurs on the following
case.
• The CD-R guide (stacker) is in
the CD-R printing position at
power-ON.
• The CD-R guide (stacker)
position does not match with
the print job.
[Major Occurrence Timing]
• Power-on timing
• Print start timing
• Print timing
[Troubleshooting]
• When the error occurs at
turning on the printer, set the
CD-R guide (stacker) in the
lower paper position.
• When the error occurs at
printing, set the CD-R guide
(stacker) in correct position
according to the print job.
• If the error occurs again though
confirming two of the above,
check CD-R Guide Sensor /
Main Board.
