Function Used to adjust the print image position and the
(Purpose) void area (image loss) on print paper. (Adjustment
as the print engine) (This adjustment is reflected
on all the FAX/printer/copy modes.)

Operation/Procedure
(Print image off-center position adjustment)
1) Enter the number corresponding to the paper feed tray to be
adjusted with 10-key. (Select one of 9 - 14.) (Table 1)
2) Press [START] key.
3) Enter the adjustment value with 10-key.
4) Press [P] key or [START] key. When [START] key is pressed,
the adjustment value is set and printing is performed. (Table 2)
Check the off-center of the self-print patter of print-out.
(Shift for the adjustment value change: 0.1mm/step)
The greater the adjustment value is, the more the print image is
shifted to the front.
(Lead edge void area adjustment)
1) Set the lead edge void adjustment value (DENA) as specified
below.
(Standard set value) Paper lead edge void: 3.5mm (DENA: 35)
∗ Set the adjustment value of DENA to 35. Enter 35 as the
adjustment value of DENA, and press [P] key.
2) Check the lead edge void area on the self print pattern.
(Enter 1 and press [START] key.)
3) If the adjustment result is not satisfactory, perform the follow-
ing procedures.
∗ If the lead edge void area is not 3.5mm:
Change the adjustment value of RRCB and perform the
adjustment. (Change the adjustment value of RRCB and
press [START] key.)
(Shift for the adjustment value change: 0.1mm/step)
(Front/rear frame direction void area adjustment)
Adjust so that the total of the front/rear direction void areas is
7.0mm. (Change the adjustment values of FRONT/REAR, and
press [START] key.)
Front frame void area = 3.5mm
(Paper resist adjustment)
1) Enter the number corresponding to the paper feed tray to be
adjusted with 10-key. (Select one of 4 - 8.) (Table 1)
2) Press [START] key.
3) Enter the adjustment value with 10-key.
4) Press [P] key or [START] key. When [START] key is pressed,
the adjustment value is set and printing is performed. (Table 2)
If the relative positions of paper and print images vary or a paper
jam occurs, change the adjustment value.
(Print condition setting in this simulation)
∗ To select paper (paper feed tray), perform the following proce-
dures.
1) Enter 0 with 10-key.
2) Press [START] key. (The mode is changed to the paper feed
tray selection mode.)
3) Enter the number corresponding to the paper feed tray to be
used with 10-key. (Select one of 1 - 5.) (Table 3)
4) Press [START] key. (The paper feed tray is selected.)
When the total of the above set value (1 - 5) and 10 is entered, the
mode is changed to the duplex print mode.
NOTE: When [P] key is pressed after entering the adjustment
value in this simulation, the adjustment value is set. When
[START] key is pressed instead, the adjustment value is set
and copying is performed.
Rear frame void area = 3.5mm
