Fault Correction

7.1

Types of Errors

The diagnostic system indicates on the screen if an error has occurred. The printer is set into one of the three
possible error states according to the type of error.
State
Correctable error
Irrecoverable error
Critical fault
Table 5 Error states
Attention!
!
State "Correctable error" :
The labels, which are printed by the lower printer but not yet printed by the upper printhead when the error
occurs, cannot be repeated by the printer. So the amount of the printed label will be reduced within the
print job.
If necessary print more labels in a new job.
If the print job contains counters, after pressing the pause key the print job would be resumed with
erroneous counter values.
Quit the print job with the cancel key.
Start a new print job with adapted counter values.
