Fault Indicators
If the printer indicates “printer fault,” the error is not recoverable. The printer must be restarted and may lose
information. To aid in printer troubleshooting, the RESUME key will activate an extended diagnostic
indication. This will blink the status indicator a number of times. The number of blinks indicates the fault.
The list of errors follows.
Faults while in operation:
1
Motor move time out
2
Motor move retry fault
3
Motor move fault (moved in wrong direction)
4
Space motor locked
5
Motor homing fault
6
Motor acceleration fault
7
Printing fault
8
Fault while centering
9
Forms compensation fault
Faults during Level 0 diagnostics:
10
ROM check-sum failure
11
RAM failure
12
Configuration EEPROM failure
13
Processor test fault
14
EEPROM check-sum failure
Faults that can happen any time:
15
Firmware control fault (loss of program control)
16
Cutter option fault
17
MICR option fault
18
MKLINK fault (cutter or MICR option selected and not installed)
After the fault code is displayed, pressing the RESUME and RELEASE keys at the same time will restart the
printer.
If the EEPROM check-sum fault occurs (Fault Code 14), the EEPROM can be set to default by pressing the
RESUME and LF keys simultaneously. The printer will be functional but must be reconfigured. This
procedure is only to allow reconfiguration and not to recover printer function in the field.
If the indication is “printer failure,” the printer controller is not running and is being held in reset. If printer
failure occurs, the printer is not functional and should be serviced.
If the printer appears to go through a power cycle by itself, the hardware watchdog has detected a fault. The
fault is generally a hardware failure or an external interference. If the fault is hardware, the printer will
continue to cycle through its diagnostics and then reset. If this happens, the printer must be serviced. If the
fault is caused by external interference like electrostatic discharge (ESD), the printer will generally recover by
itself. (Note: the parallel port INIT pin causes a soft reset).
