MX-3640N  ADJUSTMENTS AND SETTINGS  5 – 84

* Item A, B: When the adjustment value is increased, the scan 

timing is delayed.

* Item  C -   H: When  the  adjustment valu e  is increased, the

image loss is increased.

* Item A - H: 1 step = 0.1mm change
* The RSPF rear edge image loss setting is provided for coun-

termeasures against the case when shades are produced.

(Lead edge image loss adjustment)
1) Set the lead edge image loss adjustment values (LEAD EDGE

(SIDE1/SIDE2)  on  the  front  surface  and  the  back  surface  to

the following values.
(Standard set value)
TRAIL EDGE (SIDE 1): 

40 Lead edge image loss set value (Front surface)

TRAIL EDGE (SIDE 2): 

40 Lead edge image loss set value (Back surface)

(When the set value is increased, the lead edge image loss is

increased.)
(Change for change in the set value: 0.1mm/step)

2) Make  a duplex copy  in  100% in  the  RSPF  mode.  Check  to

confirm that the lead edge image loss is within 4.0  1.0mm on

the front surface and the back surfa ce. The paper lead edge

must be aligned with the presumed image lead edge.

If  the  above  condition  is  not  satisfied, p erform  the  following

procedure.

3) Enter the adjustment value of  SIDE1/SIDE2 with 10-key, and

press [OK] key.
Adjust  so  that  the  paper  lead  edge  is aligned with  the  pre-

sumed image lead edge.
SIDE1: Front surface lead edge scan position adjustment
SIDE2: Back surface lead edge scan position adjustment
(When the adjustment value is increased, the print image posi-

tion is shifted to the delaying direction for the paper.)
(Change for change in the set value: 0.1mm/step)

Perform  the procedur es  of 2)   - 3) until a satisfactor y  result  is

obtained.
(Rear edge image loss adjustment)
1) Make  a duplex copy  in  100% in  the  RSPF  mode.  Check  to

confirm that the rear edge image loss is 2.0 -  5.0mm on the

front surface and the back surface.

If  the  above  condition  is  not  satisfied, p erform  the  following

procedure.

Various adjustments

2)

Setting of the specifications and functions

3)

Canceling troubles

4)

Operation check

5)

Counters check, setting, clear

6)

Machine operating conditions (operation hysteresis), data
check, clear.

7)

Various (adjustments, setting, operation, counters, etc.) data
transport.

The operating procedures and displays depend on the design of
the operation panel of the machine.

1)

Double-click the [HOME] key. (Total use quantity/Toner
remaining quantity display mode screen)

2)

Touch the VER display section. (10-key mode input mode
screen)

3)

Touch the (#) key 

 Asterisk (*) key  Clear key  

Asterisk (*) key 

 Ready for input of main code of simulation.

4)

Enter a main SIM code with the 10-key pad then touch the
START key or select a main code from the SIM key list on the
touch panel.

5)

Enter a sub code with the 10-key pad, then touch the START
key or select a sub code from the code list on the touch panel.

6)

Select an item with the scroll key and the item key.

7)

The machine enters the mode corresponding to the selected
item. Press [START] key or [EXECUTE] key to start the simu-
lation operation.

To cancel the current simulation mode and change the main
code and the sub code, press [BACK] key.

1)

Press [EXIT] key.

Do not turn OFF the power when the machine is in the simulation
mode.

If the power switch should be turned OFF in the simulation mode, a
