Flashing Error state. 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.
