46 15 Used to adjust the print density in the FAX mode
(each super fine mode). (Only when FAX is
installed.)
16 Used to adjust the print density in the FAX mode
(each ultra fine mode). (Only when FAX is
installed.)
17 Used to set the gain in shading correction.
18 Used to adjust the gamma (density gradient) in the
copy mode.
19 Used to set the auto mode operation specifications
in each mode (copy, scan, FAX).
20 Used to adjust the copy density correction in the
SPF copy mode for the document table copy
mode. The adjustment is made so that the copy
density becomes the same as that of the
document table copy mode.
21 Used to adjust the scanner exposure level in all the
scanner modes.
22 Used to adjust the scanner exposure level in the
normal text mode.
23 Used to adjust the scanner exposure level in the
fine text mode.
24 Used to adjust the scanner exposure level in the
super fine text mode.
25 Used to adjust the scanner exposure level in the
ultra fine text mode.
27 Used to adjust the gamma (density gradient) of the
network scanner mode.
31 Used to adjust sharpness of the copy mode.
39 Used to adjust sharpness of the FAX mode.
45 Used to adjust the image density in the FAX mode
(600dpi).
46 Used to adjust sharpness of the scanner mode.
48 1 Used to adjust the copy magnification ratio (in the
main scanning and the sub scanning directions).
5 Used to adjust the copy magnification ratio in the
sub scanning direction.
6 HSYNC cycle adjustment
49 1 Firmware updating
50 1 Used to adjust the copy image position and the
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)
2 Used to adjust the document scan position, the
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 Used to adjust the print image position and the
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.

Function (Purpose)
Sub
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.)
6 Used to adjust the DSPF width detection level.
7 Used to enter the SPF width detection adjustment
value.
8 Used to adjust the document scan start position.
(Used to adjust the scanner scan position in the
SPF mode front scan.)
1 Used to set the specifications of the engine control
operations. (PCU PWB)
2 Used to set the specifications of the scanner
control operations. (Scanner control PWB)
3 Used to set the specifications of the controller
operations. (MFP control PWB)
1 Used to transfer the MFP controller data. (Used to
repair the PWB.)
1 Used to check the MFP control (DRAM) operations
(read/write).
1 Used to check the operation of the scanner (write)
unit (LSU).
2 Used to adjust the laser power (absolute value) in
the copy mode.
3 Used to adjust the laser power (absolute value) in
the FAX mode.
4 Used to adjust the laser power (absolute value) in
the printer mode.
1 Used to format the hard disk. (Only in the model
with a disk installed)
2 Used to check the operation of the hard disk (read/
write). (Only in the model with a disk installed)
(Partial check)
3 Used to check the operation of the hard disk (read/
write). (Only in the model with a disk installed) (All
areas check)
6 Used to check the operations of the hard disk.
(The self diag operation of the SMART function is
executed.) (Only in the model with a disk installed)
7 Used to check the operations of the hard disk.
(The result of the self diag operation of the SMART
function is printed out.) (Only in the model with a
disk installed)
8 Used to format the hard disk (the system area
excluded). (Only in the model with a disk installed)
