When an optional paper feed desk is connected to the machine,
unpack and install the paper feed desk, then unpack the machine.
Place the machine on the option desk securely, and perform the
installing procedures of the machine.
Place the machine on the optional desk firmly and secure.

Be careful not to leave fingerprints or oily dirt on the DV roller sur-
face.

1)

Open the front cabinet. Slide the lock to release, and remove
the waste toner box.

2)

Turn the drum cover securing locks (2) to release, and then
raise the drum positioning cover.

3)

While pressing the lever, pull out the developing unit to
remove.

4)

Open the cover to remove.

5)

Loading developer to the developing units.

Be sure to shake the bag of developer thoroughly before pour-
ing into the developing unit.

When pouring the developer into the unit, use care to not get
developer in to the drive section.

6)

Attach the cover.

7)

Shake the developing unit several times horizontally and
strongly.

8)

Open the toner shutter of the developing unit and check to
confirm that there is proper amount of developer. If not, per-
form procedure 6) again.

• Check that there is proper amount of developer. 

(The stirring screw can be partly seen.)

• There is no developer in the shutter position.

• There is too much developer. 

(The stirring screw cannot be seen.)

Be sure to keep the developing unit level while supplying the
developer.

9)

Insert the developing unit so as not to give a strong shock to
the main unit gently.

Slide the developing unit horizontally into the machine, in the
direction of the arrow, until developing unit locks into. place.
Do not push the unit diagonally, as contact with the drum may
occur causing damage.

When removing or installing the developing unit, put your hand
from below the unit and slide it in parallel along the guide. 
At that time, be careful not to touch the roller surface.

When installing the machine, there is no need to remove or
install the OPC drum unit. If it must be removed or installed for
any reason, follow the procedures below. When removing or
installing the OPC drum unit, put your hand from below the unit
and slide it in parallel along the guide on the right side. 
At that time, be careful not to touch the OPC drum surface.

10) Close the drum positioning cover, and lock it.

11) Re-install the waste toner box and lock into place.

Setting of the reference toner density control level must be per-
formed with the toner cartridge removed.

If setting is performed with the toner cartridge installed, the EE-EL
error or an overtoner trouble may occur.

1)

With the front cabinet open, connect the power plug to the
power outlet.

2)

Turn ON the main power switch of the machine and the power
switch on the operation panel.

3)

Enter the SIM25-2 mode.

4)

After entering the simulation, close the front cabinet.

5)

Select K, C, M, Y and then press the [EXECUTE] button. The
system then performs the simulation, samples the toner den-
sity control sensor value, and sets (stores in memory) the
average sensor detection level as the control level for the ref-
erence toner density. (Operating times: approx. 1.5 minutes)

Be sure to select all of the four colors: K, C, M, Y.

6)

After the machine completes cycling, exit the simulation mode.

7)

Confirm that “Install the toner cartridge” is displayed, and
install the toner cartridge by the following procedures.

8)

Shake the toner cartridge horizontally several times.

9)

Open the front cabinet, and insert each toner cartridge.

Be sure to install the color cartridges to their proper positions.
Avoid installation to a different color position.

Do not forcibly insert the toner cartridge.

Push it in until the cartridge is securely locked in place.

Developing units removed, be sure to remove the toner car-
tridges as well to prevent toner clogging.

10) Close the front cabinet.

11) Confirm that "Toner replenishment in progress" is displayed,

and wait until the display disappears. (It takes 30 sec - 6 min.)

This procedure is for checking the toner supply operation from
the toner cartridge to the DV unit. The operation time differs
depending on the toner quantity in the toner cartridge, uneven
distribution of toner, and the inside state of the toner cartridge.

Do not perform operations which interrupt the above operation,
such as opening the front cover, entering the SIM mode, and
turning OFF/ON the power. If this precaution is ignored, an
error of F2-40 - 43 or F2-64 - 67 may occur or an overtoner
may be caused.

Dust from the transfer belt or shutter or some other adjacent part
may fall onto the LSU during transport or installation. Be sure to
clean the dust-proof glass and PTC wire before checking the image
quality.

1)

Open the front cabinet. Slide the lock to release, and remove
the waste toner box.

2)

Detach the LSU cleaning bar from the front cover.

3)

Turn the felt side of the cleaning bar downward and insert it.
Slide it back and forth a few times to clean the LSU dust-proof
glass.
