Note • Signal names starting with "n" are active LOW signals.
Error Signaling
All errors that are not reset when status is read will set the nFault signal, for example:
• Head lifted
• Cutter not home
• Out of paper
This error also sets the Paper Out/End (PE) together with nFault:
• Out of paper
Note • The signaling of nFault and PE can be switched on/off with parameter p5.
