Printout Of Scanning Compensation Data (Function Code 05) - Brother DCP-9040CN Service Manual

1.4.2 Printout of Scanning Compensation Data (Function code 05)

<Function>
The machine prints out the black and white level data for scanning compensation.
<Operating Procedure>
Do not start this function merely after powering on the machine but start it after carrying out a
sequence of scanning operation. Unless the machine has carried out any scanning operation,
this function cannot print out correct scanning compensation data. This is because at the start
of scanning operation, the machine initializes black and white level data and takes in the
scanning compensation reference data. The printout varies depending on whether black and
white or color scanning is performed immediately before this operation. Check the black and
white level data you want to print out before the operation.
(1) Take a black and white copy for black and white scanning, and take a color copy for color
scanning.
(2) Press the 0 and 5 buttons in this order in the initial stage of the maintenance mode.
The "PRINTING" will appear on the LCD.
(3) The machine prints out the scanning compensation data list 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)
Color scanning
a) Black and white data graph
b) LED PWM data
c) LED pulse data (G)
d) LED pulse data (B)
e) LED pulse data (R)
f) RLCV (AFE parameter)
g) OFFSET (AFE parameter)
h) GAIN (AFE parameter)
i) Background color
compensated data
i) Black level data
k) White level data (R)
l) White level data (G)
m) White level data (B)
(4) Upon completion of recording of the compensation data list, the machine beeps for one
second and returns to the initial stage of the maintenance mode.
