Important Notes for When Replacing the Charge Corona Unit and PCU
l When you Replace the Charge Corona Unit:
1. Do not straighten the cleaner motor harness if this harness is white.
l From May 2006 production, the material of the harness was changed to a more
environmentally-friendly type. The new harness is white and the material is
harder than the black harness.
l The new harness is bent at the factory. This is to make sure that harness does
not push the quenching lamp (QL).
l If you straighten the white harness, an error will be displayed (“Reset Charger
Correctly”).
2. If this occurs when you install the charge corona unit:
This means the white harness is straight, and is pushing on the QL/holder connection
(see the photos on the next page).
Action: Correct the QL position and bend the white harness so that it does not push
the QL.
