Fault / Issue
Possible Cause / Fix
Gutter Error
1. Check the alignment of the Jet. Ensure the ink stream in going into the gutter.
2. Listen for a steady vacuum.
3. Check continuity of the gutter sensor to the CPU.
Printhead Temperature Error
1. Check the Nozzle temperature In the Status Screen.
2. Check the temperature probe connections in the top of the Printhead.
No Deflection Voltage
1. Ensure the Printhead cover is closed and the HV symbol is displayed on the main
screen.
2. Check the low voltage connections from the CPU to the HV module.
3. Check the connection of the red HV wire to the HV module.
4. Check the continuity from the HV deflection plate to the end of the HV wire at the HV
module.
Electronics Temperature Error
1. Ensure the fan is operating.
2. Ensure the Air filter is not clogged (replace if needed).
High Voltage Trip
1. Verify the HV Trip set point.
2. Ensure the Deflection Plates are clean and dry.
3. Watch for Ink buildup due to lack of grounding.
4. Check the Jet alignement.
Modulation Error
1. Check for Ink stream breakup.
2. Check for any tripped fuses.
3. Ensure that Printhead components are clean and dry.
4. Check the continuity of the Resonator Probe.
5. Verify the modulation calibration.
High Viscosity Error
1. Ensure all the Fill caps are on tight.
2. Check the Makeup Add Valve for operation.
3. Ensure the Makeup Filter is primed.
4. Verify the Viscometer Calibration Constant is the same as stated on the Calibration
Label located inside the front door.
Low Viscosity Error
1. Verify the Viscometer Calibration Constant is the same as stated on the Calibration
Label located inside the front door.
2. Ensure the Makeup Add Valve is not stuck open. This error will also be indicated if
the Ink tank is overfull while the Makeup tank is in a low status.
Viscometer Sensor Error
1. Verify the Viscometer Calibration Constant is the same as stated on the Calibration
Label located inside the front door.
2. Check the operation of the Viscometer Valve.
3. Ensure the ball is moving (use a test sensor).
4. Check the operation of the sensor - observe the LED9 on the CPU board.
Ink Leaking From Gutter (poor
vacuum)
1. Check the adjustment of the Venturi. (see Section 6/Service
Routines/Changing/Cleaning the Venturi Restrictors)
2. Check that the restrictors are the correct type.
3. Ensure the restrictors are not clogged.
4. Verify the Jet alignment.
5. Check the gutter tube connections (inlet & outlet) under the Service Module.
6. Reseat or replace the Service Module
