void area (image loss) adjustment on print paper in 
the copy mode. (The similar adjustment can be 
performed with SIM 50-5 and 50-2 (Simplified 
method).) (Document table mode)

image print position, and the void area (image 
loss). (Simple adjustment) (This adjustment is the 
simple method of SIM 50-1.) (Document table 
mode)

5

void area (image loss) on print paper. (Adjustment 
as the print engine) (This adjustment is reflected 
on all the FAX/printer/copy modes.)

6

Used to adjust the copy image position and void 
area (image loss) on print paper in the copy mode. 
(The similar adjustment can be performed with 
SIM 50-7 (simple method).) (SPF mode)

7

Used to adjust the copy image position and void 
area (image loss) on print paper in the copy mode. 
(The similar adjustment can be performed with 
SIM 50-6.) (SPF mode)

10

Used to adjust the print image off-center position. 
(Adjusted separately for each paper feed section.)

12

Used to adjust the scan image off-center position. 
(Adjusted separately for each scan mode.)

27

Used to adjust the image loss of the scan image in 
the FAX/scan mode.

2

Used to adjust the contact pressure of paper on 
the resist roller of each section (each paper feed, 
duplex feed and SPF paper feed of the copier). 
(This adjustment is required when the print image 
position variations are considerably great or when 
paper jams occur frequently.)
