PX940 Applicator Interface Installation Instructions 23
Reprint
This signal works much the same way as startprint. The reprint signal is
detected under two conditions:
• when the printer is idle.
• when the printer is waiting for a startprint signal during the execution of a
printfeed command.
The printer prints only one label at a time.
Handling External Applicator Errors
The external applicator error in signals (APPERR1, APPERR2, APPERR3,
RTWINEXT) should be asserted when external applicator errors occur. When
one of these signals is detected, an associated event is activated in the System
Health Monitor (SHM). When the issue causing the error has been resolved and
the error signals are de-asserted, the events are deactivated in the SHM.
Handling Internal System Errors
When a system error occurs that activates an event in the SHM, the “service
required” signal is asserted. The external RTW out signal can be de-asserted,
depending on the current print engine RTW setting.
When any of these errors occur, the appropriate out signal (including the error)
is asserted:
• Printhead lifted
• Ribbon out
• Media out
• General print engine fault
•Front arm lifted
• Verifier calibration required
• Verifier calibration expired
• Exceed maximum barcodes
• Verifier hardware error
• Verifier failure action prompt
