4. TROUBLESHOOTING.
When errors occurring during cutting or after powering on the machine, some LED code may appear on the
LED bar to inform you about the kind of error.
In general 2 different types of error messages may occur :
4.1. Recoverable errors.
Recoverable errors can be recognized by some flashing LED’s on the LED bar. Sometimes the machine
continue to work while LED’s are flashing. Sometimes it stops but continue again after correction of the
error.
Recoverable errors are mostly related to communication problems or user mistakes.

4.2. Unrecoverable errors.
Unrecoverable errors can be recognized when all LED’s are flashing and the machine has stopped working.
After pressing the [ENTER] key VERY SHORT (just touch it ones) the error code appears on the LED bar
(NOT flashing).
To clear the error message, the machine needs to be powered OFF and ON again. (Wait ± 7 seconds
between power OFF/ON).
