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.
