8. ERROR PROCESSING

If the printer detects any of the following errors, it will display the error message (LCD, LED), makes status response (serial interface, parallel interface), and stops its operation.

8.1COMMUNICATION ERRORS

(1)Command Errors

An error results if a command length error, command transmission sequence error, command format error, or parameter designation error is found in analyzing the command. An error results if the Format Command of a field is not transmitted and its Data Command is transmitted. When attempting to call a PC Save Command of a save identifier which is not saved, an error results. An undefined command is not detected as an error, and data is discarded until [NUL] or [}] is received.

(2)Hardware Errors

An error results if a framing error, overrun error, or parity error is found during data reception when using the serial interface (RS-232C).

*At the moment when a command error or hardware error occurs, the printer displays the error message and makes status response before stopping. The Status Request Command and Reset Command only can be processed and other commands are not processed. When the printer is restored by the [RESTART] key, the printer enters the initial state which is obtained after the power is turned on.

8.2ERRORS IN ISSUING OR FEEDING

(1)Feed Jam

When the relation between the programmed label (or tag) pitch (A) and the label (or tag) pitch detected by the sensor (B) is not indicated by the following formula, an error will result:

(A) × 50% (B) (A) × 150%

A paper jam has occurred during paper feed.

The paper is not placed properly.

The actual label does not match the type of the sensor.

The sensor position is not aligned with the black mark.

The actual label size does not meet the designated label length.

No label-to-label gap is detected due to preprint.

The sensor is not thoroughly adjusted.

(The sensor is not adjusted for the label to be used.)

(2)Cutter Error

When the cutter home position sensor does not detect 1.5 sec or more after the cutter motor is driven, an error will result.

A paper jam has occurred at the cutter. (The cutter does not return to the home position.)

The cutter does not move from the home position.

The cutter cover is open.
