cleaning unit and pull out the unit.
2. Remove the end block covers (front and rear).
3. Clean the PCC wire and casing, or replace the
PCC wire if required.

CAUTION
• Every 200K use a cloth damped with water
to clean the casing. Use a dry cloth to clean
the corona wire.
• Check and be sure that the wire on the far
side is in the V-groove of the end block.
• Height adjustment is possible on this side

of 10 ±1 mm if the end block is replaced.
2.6.6 Removing the cleaning unit
1. Remove the cleaning unit fixing screw, and slide
out the unit.
2. To pull the cleaning unit out of slide guide, pull the
cleaning unit while holding down the lock pawl.
CAUTION
• Because the slide guides have sharp edges,
keep them in the main body.
• Lay paper in place where the cleaning unit
is put. Be sure there is no metal debris
present that can cause damage. Metal
screws, paper clips, etc. attracted by the
cleaning roller can scratch the roller and
blade.
• Because the cleaning unit has no horizontal
agitating roller, do not tilt the unit when the
cleaning carrier is in the unit.
• When the cleaning carrier is in the cleaning
unit, do not turn the unit up side down.
