Corrective Action:
If you receive a Printhead Charge Error, check the following:
1. Drop velocity. The error can be caused by:
a. Pump pressure and RPS (high or low).
b. Filter status (clogged/dirty).
c. Ink viscosity (high or low).
2. A dirty Printhead, Phase Detector & Charge Electrode is covered in Ink.
3. Poor breakup/modulation:
a. No breakup. Check Modulation Cable/Fuse.
b. Satellites, ligaments (very long tails on the drops) or not breaking off in the center of
charge electrode.
c. Incorrect modulation. Check settings against factory settings label.
4. No charge applied. Check charge cable.
5. Incorrect ink stream alignment thru the Charge Electrode. Must be centered. See Fig 1 & 2 below.
6. Check the gold charge contact located under the charge electrode block. (shown below without
connecting wire - Fig 3)
