1.3.2 Printout of scanning compensation data (Function code 05)
<Function>
This function is used to print the contrast level data for document scanning compensation.
<Operating procedure>
(1) For white and black scanning, copy the document. For color scanning, implement color
copy of the document.
(2) Press the 0 and 5 keys in this order in the initial state of the maintenance mode.
The “1. FRONT 2. BACK?” will appear on the LCD.
(3) When you press the 1 or 2 key, the message “PRINTING” appears on the LCD and the
machine prints the list of the data for document scanning compensation including the
following data.
(4) When printing is finished, the machine returns to the initial state of the maintenance
mode.
■
Output data (for both monochrome and color)
Note:
- Be sure to execute this operating procedure not immediately after the power is turned
ON, but after conducting the document scanning operation at least once in scanning.
Since the machine initializes the brightness 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 brightness
level data you want to print and implement the operation below.
Note:
If there is no paper in the paper tray, the print job is canceled.
