2-2-2 ERROR LED blinking pattern
The printer stops all printer operations for the selected paper section, goes off line, and the ERROR LED
blinks when an error is detected.
• Errors that automatically recover
Error Description ERROR LED blinking pattern Recovery
Rear cover open error
(When recoverable
Error is selected)(*1)
The rear cover is opened
when printing
Recovers automatically
when the rear cover is
closed.
Print head
temperature error(*2)
The temperature of the
print head is extremely
high.
200ms
Recovers automatically
when the print head
cools.
NOTES
(*1) These conditions are selected by MSW8-5, 8-8. When MSW8-5 (mapping of the cover open status)
is off, the error hasn’t occurred but there is a “paper end error” instead. If MSW8-8 is off, this error
is handled as an automatically recoverable error.
(*2) Print head temperature error is not abnormal.
• Recoverable errors
When a recoverable error occurs, after the cause of the error is removed, the printer can recover from the
error by receiving an error recovery command without turning off the power.
