Printout of scanning compensation data (Function code 05)

<Function>
The machine prints out the white and black level data for scanning compensation.
<Operating procedure>
Note:
- 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.
- The print result varies depending on whether implementing color scanning or black and
white scanning immediately before this operating procedure. 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
copy of the document.
(2) Press the 0 and 5 buttons in this order in the initial state of the maintenance mode.
The "PRINTING" will appear on the LCD.
(3) The equipment prints out the scanning compensation data list (Refer to
7-2) containing the following:
■
Black and white scanning
a) Black and white data graph
b) LED PWM data
c) LED pulse data (G)
d) RLCV (AFE parameter)
e) OFFSET (AFE parameter)
f) GAIN (AFE parameter)
g) Background color compensated data
h) Black level data
i) White level data (G)
j) White level data (B)
k) White level data (R)
