11) Install each developer unit.

* When installing the developer unit, be sure to check that the

DV lock lever is open.

12) Secure with fixing screw. Lower the DV lock lever until it clicks

closed.

13) Close the drum positioning unit, and tighten the blue screw.

14) Install the waste toner box.

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. 3 minutes)

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

6)

After the machine completes cycling, exit the simulation mode
by pressing the [CA] key on the main unit.

* The life of each toner cartridge is as follows:

Black toner cartridge: equivalent to approximately 40K (A4/LT

tomer's request.

To customize the following items after completion of the destination
setup, change the set values.

Make a copy in the original table mode and in the RSPF/DSPF
mode. Check to confirm that the image loss and the void area are
in the range shown below.

Type

Select the type of paper that is loaded in the tray. 
The paper types that can be selected vary by paper 
tray.

Size

Select the paper size from the list. The paper sizes 
that can be selected vary by tray. The sizes that 
can be selected may also be restricted by the paper 
type selected above. 
If the desired size does not appear in the list, select 
[Custom Size] and directly enter the size (only for
