8. ERROR PROCESSING
If the printer detects any of the following errors, it will display the error message (LED), makes status
response (serial interface, parallel interface and USB interface), and stops its operation.
8.1 COMMUNICATION ERRORS
(1) Command Errors
An error results if a command length error, command transm ission 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 transm itted. W hen
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 err or, over run er ror or parity error is f ound dur ing data rec eption 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 Comm and 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) Feed Jam
W hen the relation between the program m ed 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.)
If the stripped label does not cover the strip sensor when printing or feeding is com pleted in
strip mode, an error will result.
