Purpose Adjustment
Function Color image density sensor adjustment (Adjustment
(Purpose) by the adjustment jig)
Section Process (Transfer)
Operation/ 1. Open the front cover of the machine.
Procedure 2. Install the color image density sensor adjustment
jig to the transfer unit frame, and close the left
cabinet.
3. With the front cover of the machine open (cover open/close
switch OFF), turn on the power.
4. Enter the SIM44-13 mode.
5. Close the front cover of the machine.
6. Press the [EXECUTE] key.
Adjustment is performed automatically. After completion of
adjustment, the result is displayed and the [EXECUTE] key
display returns to the original state.
7. Remove the color image density sensor adjustment jig.

Setting
Used to store color balance adjustment data. (Half
tone image correction initial setting) (After execution
of color balance adjustment with SIM 46-21, this
simulation must be executed.)
Picture quality
1. Press the [EXECUTE] key, and it is highlighted
and the operation of color balance adjustment
data (half-tone correction initial data) storing is
started.
After completion of the execution, the
[EXECUTE] key returns to the normal display
∗
In case of an error in the above operation,
"ERROR" is displayed and the color balance
adjustment data (half-tone initial data) are not
stored.

Adjustment/Setting/Operation data output, check
(display, print)
Used to check each color toner patch image density
UITU in half tone image forming section correction
(process correction). (This simulation allows to
check if correction operation is performed normally.)
Process (Photoconductor, developing, transfer,
cleaning)
Data Operation data (Machine conditions)
The toner image patch density data in half-tone
correction are displayed.
[1ST STEP]: The toner image patch density
sampling data in the 1ST STEP are displayed.
[2ND STEP]: The toner image patch density
sampling data in the 2ND STEP are displayed.
