6-22 Clean the Ionizer Bar
Clean the Ionizer Bar
Clean the ionizer bar as needed to maintain its efficient opera-
tion. The ionizer bar cannot eliminate static charges if it is dirty or
if its cable is not securely connected.
A buzzing noise at the ionizer bar, and a flickering of the orange
neon bulb at the service end of the bar, indicates reduced ionizer
efficiency. This may be due to oxidation or buildup on the tita-
nium pins, lack of a good earth ground, or an incomplete cable
connection.
The ionizer bar is attached to the printhead carriage rail.
1. Switch off power to the ionizer bar.
The ionizer bar’s power supply is mounted inside the cover
on the lower service end of the printer. The power switch is
located on the side of the power supply.
2. Verify that the cable connected to the service end of the ion-
izer bar is fully seated and completely threaded into position.
3. Use an ohm meter to measure the resistance between the
metal electronics assembly and the metal bars that run the
length of the ionizer bar.
The measurement should be less than 1 ohm after subtract-
ing the resistance of the test leads. If so, no cleaning is nec-
essary. Go to step 5.
4. Brush the titanium pins with a soft metal bristle brush (part
number 0602665).
