4.2 Printout of Scanning Compensation Data (Function code 05)
<Function>
The machine prints out the white and black level data for scanning compensation.
<Operating Procedure>
Implement the operating procedure below after scanning the document once at least, not
immediately after the machine is turned on. Since the machine initializes the white and black
level data and obtains the standard value for document scanning compensation when
starting scanning the document, the correct data for compensation cannot be printed out
even if this operation is implemented without scanning the document.
(CCD model)
The print result will be different depending on whether the document scanning performed just
before this procedure is color scanning or white and black scanning. Make sure the white
and black level data you want to print and implement the operation below.
(1) For white and black scanning, copy the document. For color scanning, implement color
scanning of the document.
(2) Press the [0] and [5] keys in this order in the initial stage of the maintenance mode.
The "WHITE LEVEL 1" will appear on the LCD.
(3) The machine prints out the scanning compensation data list containing the following:
■ Black and white scanning
■ Color scanning
a) Dark output adjustment value (CH0) 1Byte
b) Dark output adjustment value (CH1) 1Byte
c) Bright output adjustment value (CH0) 1Byte
d) Bright output adjustment value (CH1) 1Byte
e) Background color compensated data 1Byte
f) Black level data (CH0) 2Byte
g) Black level data (CH1) 2Byte
h) White level data (G) by previous scanning pixel count
i) White level data (B) by previous scanning pixel count
j) White level data (CH2) by previous scanning pixel count
a) Dark output adjustment value (G) 1Byte
b) Dark output adjustment value (B) 1Byte
c) Dark output adjustment value (R) 1Byte
d) Bright output adjustment value (G) 1Byte
e) Bright output adjustment value (B) 1Byte
f) Bright output adjustment value (R) 1Byte
g) Background color compensated data 1Byte
h) Black level data (G) 2Byte
i) Black level data (B) 2Byte
j) Black level data (R) 2Byte
k) White level MIN data (G) by previous scanning pixel count
l) White level MIN data (B) by previous scanning pixel count
m) White level MIN data (R) by previous scanning pixel count
