Push the electrode cleaner onto the electrode tip so that the elec-
trode tip comes into the electrode cleaner to clean. (repeat two or
three times.)

Note:

•

Do not move the electrode cleaner with the electrode tip
in it.

•

When cleaning, clean all the electrodes evenly.

Install the electrode to the original position and fix with the fixing
screw (1 pc.).

Insert the main charger unit completely into the copier along the
guide groove.

Slightly lift the transport section open/close lever and tilt it to the
right.

Remove the driver transfer separation charger fixing screw, and
remove the transfer/separation charger unit from the copier body.

Remove the separation charger guide from the charger case.

Squeeze the transfer/separation charger wire with the charger
cleaner, and move it in the direction of the arrow which is indi-
cated on the charger to clean.

Install the separation charger to the charger case, and insert the
transfer/separation charger unit along the guide groove com-

stops.

Remove the packing fixing screw (1 pc.) of the tray paper pressing
plate.

Fit the tray size lever to the size of paper to be used.

(The size lever is of the slide type. Slide it right and left to fit with the
size of paper to be used.)

Fit the partitioning plates A and B to the paper size.

Put paper on the tray.

Set paper on the tray. At that time, do not exceed the indication
line.

Open the front cabinet.

Tilt the developing unit lever toward you, and pull out the toner
cartridge until it stops.

Slide the developing unit lock lever in the arrow direction to re-
lease lock. Hold the toner cartridge holder and slowly pull out the
developing unit until it stops.

Hold the developing unit strap, slide the developing unit lock lever
in the arrow direction again to release lock, and remove the devel-
oping unit.

Disconnect the 5P connector which connects the toner hopper
and the developing unit. Then remove the toner hopper fixing
screws (4 pcs.) of the developing unit.

Supply developer from the developer supply port of the develop-
ing unit.

5 – 6

Fix the toner hopper to the developing unit with the fixing screws
(4 pcs.) and connect the 5P connector between the toner hopper
and the developing unit. At that time, put the 5P connector har-
ness in the harness clamp attached to the toner hopper, and
process the harness.

Install the developing unit to the copier body and push it into the body
completely. Close the developing unit lever and the front cabinet.

Note: Be careful that this procedure is different from the conven-

tional simulation.

Turn on the power switch of the copier.

Note: Before executing SIM 25-1 or SIM 25-2, be sure to check that

the main charger unit is securely inserted.

Execute SIM 25-2

The touch panel shows the following display.

Touch the EXECUTE on the touch panel and execute SIM 25-2.

Adjustment is automatically made with the toner density sensor
output value displayed. After 3 min from starting stirring, the toner
density sensor is sampled 16 times and the average value is
stored as the toner density adjustment value.

Note: When the simulation is canceled before completion, automatic

reading cannot be made. Be careful not to cancel before com-
pletion.

Press the 

 key to cancel SIM 25.

Note: SIM 25-2 must be executed only when developer is replaced.

For checking of the developer adjustment value in servicing,
use SIM 25-1. (Use of SIM 25-2 to check the developer adjust-
ment value in servicing may cause abnormality in the toner
density transition.)
Be careful that this simulation is different from the conven-
tional simulations.

Open the front cover.
