3.3.3.1 Error Codes There are three possible error types: automatically recoverable errors, recoverable errors, and unrecoverable errors. ❏ For automatically recoverable errors, the user does not have to take any action. The error recovers automatically when the head temperature returns to normal or the cover is correctly closed. ❏ A recoverable error recovers by resetting the printer or sending a command from the driver after the cause of the error is eliminated. ❏ For unrecoverable errors, the printer or the power supply may be malfunctioning and must be repaired. Automatically recoverable errors Although normal printer operation is no longer possible when automatically recoverable errors occur, they do not represent printer failure. They can be recovered easily, as described below. Table 3-4 Automatically recoverable errors Error Error description Error LED flash code Recovery measure Approx. 160 ms Roll paper cover open error The roll paper cover was opened during printing. Print head temperature error A high temperature outside the head drive operating range was detected. Recovers automatically when the roll paper cover is closed. Recovers automatically when the print head cools. Note: If the temperature cannot be detected correctly, a drive circuit error occurs. Recoverable errors Although normal printer operation is not possible after a recoverable error occurs, this is not a printer malfunction. These errors can be recovered easily by turning the power on again or sending an error recovery command from the driver after eliminating the cause of the error. Table 3-5 Recoverable errors Error Error description Error LED flash code Recovery measure Approx. 160 ms Autocutter error Autocutter does not work correctly. Remove the jammed paper or foreign matter in the printer, close the roll paper cover, send the error recover command, or turn the power on to recover. 3-8 Application Development Information Rev. A
