Charge Error
No Ink Stream Breakup
Version 0.1
Possible Cause / Fix
1. Check the power to the unit.
2. Check the Power Switch.
3. Check the Mains Fuses.
1. Check the display connection to the CPU
2. Press the MENU key; this acts as a display reset.
3. This error could be due to a possible Electro-Static Discharge fault; reset the Printer.
1. Check Restrictor(s) for clogs.
2. Check Return Line to Ink Tank for clogs.
3. Check Pressure Transducer (possibly an incorrect reading).
1. Check the Fuses.
2. Check the Pump Cable.
3. Disconnect the Pump Head and perform a pump motor test (described below).
4. Check the Pump Head for a seizure (if the motor operates).
1. Check the Fuses.
2. Check the wire cable for damages if the fan is turning.
1. Check for Ink stream breakup.
2. Check the distance from the Ink stream to the Phase Detector.
3. Ensure the Ink stream is in the center of the Charge Electrode.
4. Check the pressure and viscosity (to verify Jet velocity).
5. Check the location of the Phase Amplifier to make sure it is NOT too close to the
Valve, Valve wires, or other possible source of noise. (See Section 9.2.3 Phase
Detector Alignment)
6. Check the Phase Amplifier connections.
7. Ensure you are not printing too fast (add print delay)
1. Check for Ink stream breakup (see Section 10.8).
2. Check the modulation calibration.
3. Clean and dry the Phase Detector.
4. Check the distance from the Ink stream to the Phase Detector (see Section 10.7).
5. Check the charge cable continuity from the Charge Electrode to CPU.
6. Check for clogged Filters.
7. Check pressure and viscosity (to verify Jet velocity).
8. Check the gold charge contact located under the charge electrode block. (shown
below without connecting wire)
1. Check the F2 Fuse.
2. Check for correct printing. If printing, check strobe LED connections.
