F.1.4 Error code

There are three types of error possible: Automatically Recoverable Errors, Recoverable Errors, and Unrecoverable Errors.

For the automatically recover errors, the users do not have to do anything special; instead it will recover automatically when the head temperature cools down or the cover is correctly closed. For the recoverable errors, the user needs to perform some appropriate action suitable for the error to recover.

If an unrecoverable error occurs, the printer may be damaged. Turn the power off, and take the printer to a dealer for repairs.

Automatically recoverable errors

Although normal printer operation is no longer possible when automatically recoverable errors occur, they do not represent printer failure. They are easily corrected through use of the printer's controls.

Note:

*1 Use the memory switch Msw8-8 to determine the cover open error as an automatically recoverable error or a recoverable error. (Factory default setting is Recoverable Error.)

*2 This is not any failure or abnormal condition; it just indicates an error condition in case the head temperature has become very hot due to the continuous use with heavy printing duty. If an abnormal value is detected because of the circuit, the printer judges it a drive circuit error and it becomes an unrecoverable error.
