1EH
Time Interval Setting for Shading Correction, Peak Level
Sampling, and Black Line Detection
Units: 1 s
If set to ff, shading correction is executed for only the first page
of the job.
404590 ~ 404591
03H
Continuous Count of Abnormally Wide Pixels – Uncorrectable
The continuous occurrence of abnormally wide pixels that
cannot be corrected electronically. When the number of
occurrences is so large that the SRAM capacity is exceeded, a
warning is issued.
404594 ~404595
14H
Continuous Count of Abnormally Wide Pixels – Correctable
The continuous occurrence of abnormally wide pixels that can
be corrected electronically. When the number of occurrences
is so large that the value of this SRAM is exceeded, a warning
is issued.
404960
01H
Blank Page Detection Level Setting
Sets the frequency of blank page detection. This feature
ensures that the original was loaded correctly for scanning.
01h: If the first page of the original is blank (white), the
machine judges there is a blank page.
02h: If any one page of the original is blank (white), the
machine judges there is a blank page.
03h: If all pages of the original are blank (white), the machine
judges there is a blank page.
4049C4 ~ 4049C5
4FH
Adjustment of Sub Scan Start Position for ADF Scanning
Units: 01.mm
Entering a larger value in the range 0000h ~ 009Eh lowers the
start position for scanning in the sub scan direction.
4049C6 ~ 4040C7
4FH
Adjustment of Registration for MDF Sub Scan Start Position
Units: 01. mm
Entering a larger value in the range 0000h ~ 009Eh lowers the
start position for scanning in the sub scan direction.
4049CC ~ 4049CD
0EH
Adjustment of Registration for ADF Main Scan Start Position
Units: 01. mm
Entering a larger value in the range 0000h ~ 001Ch shifts the
ADF main scanning area to the right (away from the operation
panel).
4049CE ~ 4049CF
0EH
Adjustment of Registration for MDF Main Scan Start Position
Entering a larger value in the range 0000h ~ 001Ch shifts the
MDF main scanning area to the right (away from the operation
panel).
45EE3C ~ 45EE3D

Vertical Black Line Detections
Number of jobs in which an abnormal pixel was detected
before page 1 of the original was scanned. Increments only by
1 per job.
45EE3E ~ 45EE3F

Pixels of Abnormal Width – Correctable
Increments by 1 for every abnormally wide pixel that can be
corrected electronically. The electronically correctable width
depends on a special setting made at the factory before
shipping. (Currently this width is set for 1 pixel.) Also, if
alternating pixels

are detected, the counter is
incremented.
45EE40 ~ 45EE41

Pixels of Abnormal Width – Not Correctable
Increments by 1 for every abnormally wide pixel that cannot be
corrected electronically. The electronically correctable width
depends on a special setting made at the factory. (Currently
this width is set for 1 pixel.)
