Appendix A — Error-Handling
Error-Handling Principles
The fi rmware is able to handle a number of error conditions. Code
numbers represent the different error cases.
The printer controls output of the error code and its format and wait
until the error recovery is performed for each special error-code.
Error action source
A: Command errors
The biggest group of error codes is command format and data
information error. It exists errors of type “Syntax error” to more
sophisticated like “Form or image name duplicate”. (See error type A.)
B: Printing error
Print out error occurs, when the printing the label not is correct
performed, such as “Out of media”, “cover opened”, and “cutting not
completed”. (See error type B, C, and D.)
C: Status
A status error performs normally not a true error case, but in some matter
it has to be detected. A typical case is “LTS-detection waiting”. (See error
type E.)
D: Special modes
Some special feature errors will hang the printer for ever or have a
complete other output. Typical of this group errors are: “Flashing not
completed” or “Dump mode”. (See error type F and G.)
Error action output information
The error code will often be written in the upper left corner of the label,
like “ERR01”. The control LED will go orange or red.
Serial Port (RS-232 or USB)
Output on serial line when error occurs is depending on some setup
commands.
The Command UN and US turn off or on most of the error output
information.
The Command eR specifi es the format of the error output information.
Parallel Port
At an error, the parallel port will mark error status by setting pin 12 in
active state.
