6.5.5 CLEANING BLADE REPLACEMENT

[C]
1. Remove the drum. (Refer to Drum Unit Removal and Drum Replacement.)
2. Remove the cleaning blade [A] (2 screws).
3. Clean the entrance seal [B], side seals [C] and cleaning brush [D].
NOTE: When a vacuum cleaner is used, to protect the electrical parts from
static electricity, disconnect the connector on the charge power pack
and remove the ID sensor as follows:
1) Disconnect the 12P connector on the charge power pack [E].
2) Remove the screw [F] and separate the upper and lower drum units.
3) Remove the spur bracket [G] and pick-off pawl bracket [H] (2
screws).
4) Disconnect the connector [I].
5) Slide the pick-off pawl bracket to the rear, while turning it
counterclockwise (as seen from the front),.
4. Install the new cleaning blade.
NOTE: Do not clean the edge of the cleaning blade with a cloth; this damages
the edge and causes black lines on copies.
Do not touch the edge of the new cleaning blade. If some setting
powder or toner on the blade edge is removed, apply toner at that
place.
When installing the cleaning blade, do not pinch the side seals.
