1.4.3 Printout of Scanning Compensation White/Black Level Data (Maintenance mode 05)
<Function>
This function prints out the light and dark level data for scanning compensation.
<Operating Procedure>
Note Perform this procedure after carrying out document scanning operation at least
once, not immediately after powering on the machine. Do not start this procedure
without carrying out document scanning operation. This is because at the start of
scanning operation, the machine initializes light and dark level data and takes in
the scanning compensation reference data.
The print result differs depending upon whether color or monochrome scanning is
performed preceding this procedure. Check the light and dark level data to be
output before performing this procedure.
(1) For monochrome scanning, make a monochrome copy; for color scanning, make a
color copy.
(2) Enter [0] and [5] in the initial stage of the maintenance mode.
The machine displays "DUMP 0 : GRA 1: ALL" on the LCD.
(3) To print only the light and dark data graph for each color, LED data, AFE parameters
and background color compensation data, enter [0]. To print all data, enter [1].
If no error has occurred in the machine, the machine displays "PRINTING" on the LCD
and starts printing.
If any error has occurred in the machine, "ME STATE STOP" appears on the LCD.
Note If no recording paper is loaded in the paper tray, printing will be canceled.
(4) Upon completion of printing, the machine returns to the initial stage of the maintenance
mode.
