SUBJECT: SPRING REPLACEMENT – CHARGE CORONA UNIT
SYMPTOM:
Difficulty when replacing Charge Corona Wires.
CAUSE:
The angle of the opening on the Spring is only 45°, and this makes it difficult to attach the spring. Also the
notch in the Right End Block made it difficult to attach the Spring from above.
SOLUTION:
The angle on the opening of the Spring has been changed from 45° to 90° so the Spring can be replaced
with less pulling. Also the length of the notch in the Right End Block has been changed from 4 mm to 2.9
mm so the spring end with a diameter of 3 mm can be hooked from above. See the Before and After figures
below.

The following parts corrections are being issued for all A163 Parts Catalogs.
