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.
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.
