7.1 Fault and Warning Messages (Display Printers Only)
All printer functions are internally monitored. If a problem (Fault) or a potential problem (Warning) is detected, the Error
Indicator will be illuminated. A corresponding message will be displayed. These messages, along with possible solutions,
are described below.
Fault Messages: Fault Messages receive the highest display priority. If more than one fault is detected, the display will
toggle between messages.
Note: To return to normal operation after the printer enters a fault condition, the fault must be corrected and then the FEED Key
must be pressed to clear the condition.
