General Care, Troubleshooting and Service 6-13
10. Using the cleaning tool with cloth, clean the inside of the cylinder by
slowly inserting the tool into the space between the inner and outer
column (Figure 6-13). Rotate the tool (in the direction which will not
unwrap the cloth) and slowly push it down. Continue this motion until
the cleaning tool has bottomed out at the bottom of the column.
Note: Generally, when the column gets
“noisy,” it is because a piece of
lint has collected in the charger unit and it is shorting two of the
rings. The purpose of wiping the cylinder sides is to remove any
material on the outer cylinder. The inner cylinder will generally
stay very clean due to the electric field.

Cleaning the Charger Column
11. After cleaning, reassemble the charger column and after warm-up,
zero the electrometers (see
“
Baseline Noise
” in the following section,
“
Troubleshooting
”). If the problem is still present, try zeroing the
electrometers again from the front panel. If this still does not help, the
detailed cleaning procedure described below must be performed.
