Warning and Fault Messages
System Failures
System failures occur when the software detects a condition which prevents normal printer operation.
If a system failure is reported by the printer, contact your local distributor immediately.
WARNING: LETHAL VOLTAGE. UNKNOWN HIGH VOLTAGES MAY BE PRESENT WITH SOME
SYSTEM FAILURES. DO NOT TAMPER WITH THE PRINTER OR PRINTHEAD. WAIT
UNTIL THE FAILURE SHUTDOWN IS COMPLETE.
Print Failures
Print Failures occur when the software detects a problem which affects printing.
When a Print Failure occurs a message is displayed on the screen status line and a jet shutdown
sequence is started.
The internal alarm buzzer is switched on, the ‘print ready’ line set low and the alarm relay is activated
(if enabled).
The keyboard is inactive while the shutdown is taking place.
When the shutdown sequence is complete the Print Failure screen is displayed:
The user should normally select F1 to reset the printer.
Following a print failure shutdown, the software sets:
- pressure to zero
- EHT off
- all valves closed
- 300V off these settings cannot be altered until the print failure has been cleared (i.e. the jet cannot
be restarted).
The following pages give a brief description of each Print Failure and what should be done to correct
it. In each case, if the suggested action does not rectify the error condition, you should contact your local
distributor.
2.00 Printhead Temperature
The printhead temperature sensor indicates that a temperature around or in the printhead has
exceeded the safe operating limit. This may mean that a fire has occurred within the head cover.
Possible causes
- Excessive local heat source:
Relocate the printhead away from the heat source.
- Fire in the printhead:
Have your printer checked by your local engineer.
2.01 Deflector Voltage
The voltage on the deflector plates has discharged which is normally caused by ink build-up.
Possible causes
- Excess build-up of ink on deflector plates:
Clean the printhead as described earlier in this manual (see “Routine Maintenance”).
- Static discharge:
Check for any source of excess static electricity.
- Printhead still wet after cleaning:
