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.
8.1 COMMUNICATION 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 [ESC] or [{] is
received.
(2) Hardware Errors
An error results if a framing 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 shows 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.
8.2 ERRORS IN ISSUING OR FEEDING
(1) Paper Jam
c 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.)
d If the stripped label does not cover the strip sensor when printing or feeding is completed in
the strip mode, an error will result.
