] keys.

2.  Enter the set value with the 10-key 

2. Press the [OK] key. (The value entered in procedure 2 is set.)

DV BIAS:

Developing bias base voltage (Equivalent to SIM 8-1 for Drum type B.) (500)

GIRD BIAS:

Main charger grid voltage (Equivalent to SIM 8-2 for drum type B.) (475)

LD POWER:

Laser power (Equivalent to SIM 61-2 for drum type B.)  (16)

PROCON DB:

Base developing bias voltage in toner image patch forming (in developing bias correction)
(Equivalent to SIM 44-5B) (500) (Correction value to SIM 44-5B)

PROCON GB:

Base main charger grid voltage (Equivalent to SIM 44-5A in drum type B) (500) (Correction
value to SIM 44-5A)

PROCON TARGET: Target image (reference) density level in developing bias voltage correction (Equivalent to

SIM 44-4 4 in drum type B) (58)

Be sure to set to the specified value.

Adjustment

Function
(Purpose)

Used to adjust the copy density in the copy mode (binary - auto, character, chatacter and photo, photo mode).
(The overall print density in each mode (all of the specified density set for each density level (display value)) ???
can be adjusted in each mode.)

Operation/
Procedure

1. Select the print mode with [

],[

↓

] keys.

(The set value is highlighted.)

2. Enter the adjustment value with the 10-key.

3. Press the [OK] key or the PRINT button.

The value entered in procedure 2 is set.
When the PRINT key is pressed, copying is performed.

(Note) When a set value (density adjustment value in density level 3)  in the left column of the table below is changed

with this simulation, the set value (the overall density level set value) in the right column is changed accordingly.
The parameters of the right and the left simulations and their adjustment items are the adjustment values in the
same print mode.
The result of adjustment by the simulation executed at the last is reflected in actual printing.
The print density is normally adjusted by SIM 46-2. 
To customize the print density for the density level display value according to the user’s request, use the
simulation in the right column. (Excluding auto mode/simulation 46-8.)
