8.5.2 Printout of Scanning Compensation Data
(Function code 05)
Function code 05 is not supported in the maintenance program embedded in the flash ROM of the
MFC3240C/FAX1840C U.S.A./Canadian models. To use Function code 05 in these models, you
need to temporarily load the full maintenance program onto the flash ROM. Refer to
n
Function
The machine prints out the white and black level data for scanning compensation.
n
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 white and black level data and takes in the scanning
compensation reference data.
(1) Press the
0
and
5
keys in this order in the initial stage of the maintenance mode.
The "PRINT" will appear on the LCD.
(2) The machine prints out the scanning compensation data list containing the following:
a) Black/white data graph
b) LED light intensity pulse data for green image (2 bytes)
c) LED light intensity pulse data for blue image (2 bytes)
d) LED light intensity pulse data for red image (2 bytes)
e) Compensation data for background color (1 byte)
f) Black level data (4970 bytes)
g) White level data for red image (4970 bytes)
h) White level data for green image (4970 bytes)
i)
White level data for blue image (4970 bytes)
(3) Upon completion of recording of the compensation data list, the machine returns to the initial
stage of the maintenance mode.
NOTE:
When the machine prints monochrome images after monochrome scanning, only the green
data is valid.
NOTE:
If any data is abnormal, its code will be printed in inline style.
