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 ~ 45EE45
— —
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 ~ 45EE47
— —
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).*

Abnormal Pixel Width Counter: 1~3 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 ~ 45EE4B
— —
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 ~ 45EED
— —
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 ~ 45EE4F
— —
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 ~ 45EE51

Abnormal Pixels in CIS Block 1
Increments by 1 if abnormal pixels are detected in Block 1*
2
of
the CIS.
45EE52 ~ 45EE53
— —
Abnormal Pixels in CIS Block 2
Increments by 1 if abnormal pixels are detected in Block 2*
2
of
the CIS.
45EE54 ~ 45EE55
— —
Abnormal Pixels in CIS Block 3
Increments by 1 if abnormal pixels are detected in Block 3*
2
of
the CIS.
45EE56 ~ 45EE57
— —
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.
