Trouble Shooting Other Issues

Fault Mode

The printer will enter a Fault Mode and will not operate when certain failure conditions are
encountered. Conrmation 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 ash a 3 bit code
to dene the specic 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 ash the Red LED if the RS-232 interface is
selected.
