● 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.
9.3.2. 2.00 Print Head Temperature
The print head temperature sensor indicates that a temperature around or in the print head 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 print head away from the heat source.
● Fire in the print head:
Have your printer checked by your local engineer.
9.3.3. 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 print head as described earlier in this manual (see “Daily Maintenance”).
● Static discharge.
Check for any source of excess static electricity.
● Printhead still wet after cleaning.
Allow the print head to fully dry before starting the jet.
● Debris or fibers creating a discharge path.
Clean the printhead and check for debris.
9.3.4. 2.02 Charge
This failure occurs when the jet is being started, or when it is running.
Possible causes
● Blocked nozzle or misaligned jet:
Carry out the nozzle clear procedure described in the Troubleshooting section of
this manual (see “troubleshooting - Clearing the Print Head Nozzle”).
● Print head code or modulation values set incorrectly.
Check the Print head and Modulation (MOD) values printed on the print head
serial number label found on the conduit, with the stored values. (see “Changing
the System Setup”).
