Procedure
Used to set various parameters of image forming op-
eration and image forming section correction operation
for drum type A.
1. Select the correction item with [
], [
¯
] keys.
2. Enter the set value with the 10-key
3. 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)
For AR-4XX series, set to "500" (default).
LD POWER:
Laser power (Equivalent to SIM 61-2 for
drum type B.) For AR-2X1/3X1/287/337/4XX
/250/XX6 series, set to "10" (default). For
AR-230/250/285/330/335 series, set to "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)

Be sure to set to the specified value.
Note
Be sure to set to the specified value. If not, the print im-
age density may be disturbed.

Adjustment
Function
(Purpose)
Used to adjust the copy density in the copy mode (bi-
nary/multi-value - auto, character 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)
(AR-280/285/330/335 series)
