2.5 CHARGE GRID AND CORONA WIRE REPLACEMENT
1. Remove the front and inner covers, (see procedures 1.2 and 1.9).
2. Remove the charge corona unit [A] (1 screw). Hold the toner supply
motor bracket [B] away while removing the charge corona unit.
3. To replace the grid:
Remove and replace the grid [C] (1 screw).
4. To replace the charge wire:
1) Release the hooks of the front and rear end block covers [D] and then
remove the covers from the charge corona unit.
2) Replace the corona wire [E].
NOTE: 1) Do not touch the corona wire directly. Skin oils can
deteriorate the corona wire over time, causing uneven
charging.
2) Do not bend the corona wire. If the wire is bent, it will not
discharge uniformly. This causes uneven charging.
3) Put both ends of the corona wire in the end block slots.
4) Replace the front end block cover first. If the rear end block
cover is replaced before the front cover, the corona wire may
catch on the corona wire case slot [F]. This may damage the
wire.
