Trouble Shooting Other Issues
Fault Mode
The printer will enter a Fault Mode and will not operate when certain failure conditions are
encountered. Confirmation of this condition can be accomplished by the host on the DTR (pin 8) or
status with an RS-232 interface.
The color of the LEFT LED on the front panel of the
printer will change from Green to Red if a fault condition
is encountered. Depressing the paper feed button on
the printer cover will cause the printer to enter diagnostic
mode. This will cause the LED to flash a 3 bit code
to define the specific reason the printer entered Fault
Mode. The error code is followed by a delay before
being repeated. The diagnostic code will toggle the DTR
line and flash the Red LED if the RS-232 interface is
selected.
