Static Checks for 636/656 Printers
1. Stacker: With an ohmmeter, check continuity between the main stacker
roller, which has the belts on it, and the chassis ground. Chassis ground
can be any screw near the serial cable. Check that these two important
enhancements are functioning:
a) Check the grounding clip is
installed and making physical
contact with the main stacker
roller. Sometimes, the clip is
installed but moved off the
roller.
b) Check the stacker mounting knob has a
large washer installed. Make sure to
tighten the knob all the way.
2. Ink arbors: With an ohmmeter, check
for continuity on the two ink arbors and
three ink turn rollers. Place one lead of
the ohmmeter on the arbor and the other
on the chassis ground screw.
3. Printhead static protections. Check for proper installation.
a) Static brushes. Make sure the brushes
are installed and just barely touching the
stock and ink. Too much dragging and
they wear; too little contact and they don’t
dissipate the static.
b) Static shield. Make sure the static shield
is installed and the screws are tight.
