P-1 Image void at 22mm intervals

[1] 22mm

(1/4)

iR6570-004

<Cause>
Since the process speed was increased starting with the iR5000 series, the output level of high voltage was also
increased; however, a margin for high voltage leakage was reduced. This causes high voltage leakage depending
on the position to which the Corona sheet 2 is affixed, resulting in image void at 22mm intervals.

Service Work:

When the above-mentioned symptom occurs, remove the Transfer/ Separate Corona Assembly from the Main
Unit and apply the Corona sheet 2, referring to "Service Manual > 7.Image Formation > 7.10.15 Transfer/
Separation Charging Assembly".
Work procedure

1. When a 22mm interval image occurs, check "COPIER > DISPLAY > ALARM-2" in Service Mode
(Level 1) and make sure that "300002" (transfer leak) is displayed in CODE.
