Count Detection Parameters List
Please refer to the sample on the previous page as you read the table descriptions
below.
Address Count Detection Conditions
45EE3C ~ D
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 ~ F
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 ~1
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.)
45EE42 ~ 3
Abnormal Pixels
– Consecutive
occurrence at the same
place (1 time)
Increments by 1 if an abnormal pixel occurred, but had
disappeared from that place by the start of the next job (for
example, the exposure glass was cleaned or the original
brushed away the speck of dust).*
1
45EE44 ~ 5
Abnormal Pixels
– Consecutive
occurrence at the same
place (2~9 times)
Increments by 1 if an abnormal pixel occurred at the same
place on the scan line 2 to 9 consecutive times, but was not
there at the start of the next job (for example, the exposure
glass was cleaned or the original brushed away the speck
of dust).*
1
45EE46 ~ 7
Abnormal Pixels
– Consecutive
occurrence at the same
place (10 or more times)
Increments by 1 if an abnormal pixel occurred at the same
place on the scan line 10 or more consecutive times, but
was not there at the start of the next job (for example, the
exposure glass was cleaned or the original brushed away
the speck of dust).*
1
45EE48 ~ 9
Abnormal Pixel Width
Counter: 2~3 Pixels Wide
Increments by 1 every time an abnormal pixel 2~3 times
wider than 1 pixel is detected. If more than one pixel is
detected, the counter updates once for each pixel detected.
45EE4A ~ B
Abnormal Pixel Width
Counter: 4~6 Pixels Wide
Increments by 1 every time an abnormal pixel 4~6 times
wider than 1 pixel is detected. If more than one pixel is
detected, the counter updates once for each pixel detected.
45EE4C ~ D
Abnormal Pixel Width
Counter: 7~12 Pixels
Wide
Increments by 1 every time an abnormal pixel 7~12 times
wider than 1 pixel is detected. If more than one pixel is
detected, the counter updates once for each pixel detected.
45EE4E ~ F
Abnormal Pixel Width
Counter: 13 or More
Pixels Wide
Increments by 1 every time an abnormal pixel 13 times or
more wider than 1 pixel is detected. If more than one pixel
is detected, the counter updates once for each pixel
detected.
45EE50 ~ 1
Abnormal Pixels in CIS
Block 1
Increments by 1 if abnormal pixels are detected in Block 1*
2
of the CIS.
45EE52 ~ 3
Abnormal Pixels in CIS
Block 2
Increments by 1 if abnormal pixels are detected in Block 2*
2
of the CIS.
45EE54 ~ 5
Abnormal Pixels in CIS
Block 3
Increments by 1 if abnormal pixels are detected in Block 3*
2
of the CIS.
45EE56 ~ 7
Abnormal Pixels in CIS
Block 4
Increments by 1 if abnormal pixels are detected in Block 4*
2
of the CIS.
*1
:
This counter increments by one only when an abnormal pixel that was previously detected at a certain
position has now disappeared.
*2
:
The length of the CIS (Contact Image Sensor) is divided into four blocks: Block 1, Block 2, Block 3, and
Block 4. The count is incremented only once even if abnormal pixels are detected at more than one
location in the same block.
