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 fault list follows.

Faults while in operation:

1Motor move time-out

2Motor move retry fault

3Motor move fault (moved in wrong direction)

4Space motor locked

5Motor homing fault

6Motor acceleration fault

7Printing fault

8Fault while centering

9Forms compensation fault

Faults during Level 0 diagnostics:

10ROM check-sum failure

11RAM failure

12Configuration EEPROM failure

13Processor test fault

14EEPROM check-sum failure

Faults that can happen at anytime:

15Firmware control fault (loss of program control)

16Cutter option fault

After the fault code is displayed, the printer can be restarted by pressing the RESUME and RELEASE keys simultaneously.

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 this 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. This 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.)
