Chapter 1 Product Overview Error Status There are three possible error types: automatically recoverable errors, recoverable errors, and unrecoverable errors. Automatically Recoverable Errors Error Head temperature error Cover open error in the middle of printing Description Head temperature exceeded the proper range. The roll paper cover was opened during printing Recovery The printer recovers from the error when the head temperature drops. The printer recovers from the error when the roll paper cover is closed. Recoverable Errors Error Autocutter error Description The cutter blade is locked due to a foreign object fell inside the printer or other reason. Recovery Remove foreign objects or paper, and then close the roll paper cover to make the printer recover from the error. The printer automatically recovers from the error if the blade can be unlocked easily, however, make sure to check for foreign objects before use. Instead of closing the roll paper cover, you can make the printer recover from the error using a dedicated command, however, doing so will cause the printer to go offline due to a cover open error. Unrecoverable Errors These include a high voltage error, CPU execution error, and communication unit error. If the error persists after turning the printer off and then on again, the printer may be defective. Contact qualified service personnel. If an unrecoverable error occurs, turn off the power immediately by pressing and holding the power button until the power LED flashes or by unplugging the DC cable or power plug. 21
