Grounding regulation for print head cleaning
For technical reasons the ink of a continuous ink jet printer is charged with high
voltage during the printing process. In case of inappropriate handling the static
charged ink may be an ignition source. In combination with flammable ink and
solvent this could pose a fire or explosion hazard.
Without any safety measures the ink in the service tray may be charged up during
cleaning work. In order to avoid this critical situation the print head and the service
tray have to be connected with a ground cable. In case of using a service tray
made of plastic material it would be possible to place a metal foil in the service tray
and connect the ground cable to that foil.
