Error Status; Automatically Recoverable Errors; Recoverable Errors - Epson TM-U220-i Technical Reference Manual

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.
Error
Roll paper cover
open error
(when recoverable
error is selected) (*1)
Print head
temperature error(*2)
(*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.

error.
