Printout Of Scanning Compensation Data - Brother FAX100 Service Manual

3.3.2

Printout of scanning compensation data

Function
The equipment prints out the white and black level data for scanning compensation.
Operating Procedure
Do not start this function merely after powering on the equipment but start it after carrying
out a sequence of scanning operation. Unless the equipment has carried out any scanning
operation, this function cannot print out correct scanning compensation data. This is be-
cause the equipment initializes white and black level data and takes in the scanning com-
pensation reference data at the start of scanning operation.
(1) Press the 0 and 5 keys in this order in the initial maintenance mode.
The "WHITE LEVEL 1" will appear on the LCD.
(2) The equipment prints out the scanning compensation data list containing the following:
FAX100/570/615/625
a) 2-value quantized white level data (208 bytes)
b) 2-value quantized black level data (1 byte)
c) 2-value quantized LED light intensity value (1 byte)
Other models
a) 2-value quantized white level data (208 bytes)
b) 2-value quantized black level data (1 byte)
c) Photo-mode white level data (208 bytes)
d) Photo-mode black level data (1 byte)
e) LED light intensity value, 2-value quantized LED light intensity value, and photo-
mode LED light intensity
f) 2-value quantized A/D reference value and photo-mode AD reference value
(3) Upon completion of recording of the compensation data list, the equipment returns to
the initial maintenance mode.
NOTE: If a certain data is abnormal, that code will be printed in inline style.
