Error Status
There are three possible error types: automatically recoverable errors, recoverable errors, and
unrecoverable errors. Check the error LED flash code.
When connection to peripherals fails, check the status LEDs at the lower rear of the product.
Automatically Recoverable Errors
Printing is no longer possible when automatically recoverable errors occur. They can be recovered
easily, as described below.
(*1) This conditions are selected by MSW 8-5, 8-8. When MSW 8-5 (mapping of the cover open status) is off, the error has
not occurred but there is a “paper end error” instead. If MSW 8-8 is off, this error is handled as an automatically
recoverable error.
(* 2) Print head temperature error is not abnormal.
Recoverable Errors
Printing is no longer possible when recoverable errors occur. They can be recovered easily by turning
the power on again after eliminating the cause of the error.
(*1) These conditions are selected by MSW 8-5 and 8-8. When MSW 8-5 (mapping of the cover open status) is OFF, the
error does not occur and a “paper end error” occurs instead. If MSW 8-8 is ON, this error is handled as a recoverable
error.
