MX-B381/B401  SIMULATION  5 – 54

 

44-29

Setting

Function (Purpose) Used to set the operating conditions of the

process control during a job.

Process

Operation/Procedure
1)

Select a target item of setting with [

] [] key on the touch

panel.

2)

Enter the set value with 10-key.

3)

Press [OK] key.

HV: High density process control
HT: Half tone process control

 

44-37

Adjustment/Setup

Function (Purpose) Used to set the development bias correc-

tion level in the continuous printing opera-
tion.

Operation/Procedure
1)

Select a target item with [

] [] buttons.

2)

Enter the set value with 10-key.

3)

Press [OK] key.

NOTE: When the print density is varied in the continuous printing

operation, this simulation is used.

<Use example>

 

44-43

Data display

Function (Purpose) Used to display the identification informa-

tion of the developing unit.

Developing system

Operation/Procedure
The identification number and the identification signal level of the
developing unit are displayed.

 

 

46-2

Adjustment

Function (Purpose) Used to adjust the copy density in the copy

mode.

Operation/Procedure
1)

Select an adjustment target item with [

] [] key.

2)

Enter the set value with 10-key.
* When the     key is pressed, the setting value of each

item can be changed with 1up (1down) collectively.

3)

Press [OK] key. (The set value is saved.)

To adjust the copy density in the low density area, select the "LOW"
mode and change the adjustment value. To adjust the copy density
in the high density area, select the "HIGH" mode and change the
adjustment value. 
When the adjustment value is increased, the copy density is
increased. When the adjustment value is decreased, the copy den-
sity is decreased.

(*1)

The default of A/B/C is "0" and this function is set to OFF.
When 10 sheets are copied in the multi copy mode and if the 10th 
sheet is lighter than the 1st sheet, set to the range of 1 - 5. The 
greater the value is, the darker the density of the 10th sheet is.
