Clean the Ionizer Bar 5-23
Clean the Ionizer Bar
If your printer has the optional ionizer bar installed, you should
clean it as needed to maintain its efficient operation. The ion-
izer 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 right 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.
To clean the titanium pins along the length of the ionizer bar:
1. Switch off power to the ionizer bar.
2. Verify that the cable connected to the right side of the ionizer
bar (when facing the rear of the printer) 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.
5. Switch on power to the ionizer bar.
If the pins are clean, there will be no buzzing sound, and the
orange light will remain off; otherwise, repeat this proce-
dure.
