■ Black and white/color scanning (Second side)
(4) When printing of the correction data is finished, the machine beeps for one second and
returns to the initial state of the maintenance mode.
Note:
In the case of the black and white scanning, the output data (B) and (R) are invalid.
a) Black and white data graph by previous scanning pixel count
b) LED CURRENT DATA 1 Byte
c) LED pulse data 1(UP) (G) 2 Bytes
d) LED pulse data 1(DOWN) (G) 2 Bytes
e) LED pulse data 1(UP) (B) 2 Bytes
f) LED pulse data 1(DOWN) (B) 2 Bytes
g) LED pulse data 1(UP) (R) 2 Bytes
h) LED pulse data 1(DOWN) (R) 2 Bytes
i) LED pulse data 2(UP) (G) 2 Bytes
j) LED pulse data 2(DOWN) (G) 2 Bytes
k) LED pulse data 2(UP) (B) 2 Bytes
l) LED pulse data 2(DOWN) (B) 2 Bytes
m) LED pulse data 2(UP) (R) 2 Bytes
n) LED pulse data 2(DOWN) (R) 2 Bytes
o) RLCV (AFE parameter) 1 Byte
p) OFFSET (AFE parameter) 1 Byte
q) GAIN (AFE parameter) 2 Bytes
r) Background color compensated data 1 Byte
s) Black level data by previous scanning pixel count
t) White level data (G) by previous scanning pixel count
u) White level data (B) by previous scanning pixel count
v) White level data (R) by previous scanning pixel count
Note:
- If any data is abnormal, its code will be printed in inline style.
- Regarding the black and white level data after monochrome reading is done, only the G
data is printed, and R and B data are not printed.
- The white level data and black level data are imported in 10/16 bits, and the data in the
upper 8 bits are printed.
