Printout of scanning compensation data (Function code 05)
The
machine prints out the brightness level data for scanning compensation. 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.
For
white and black scanning, copy the document. For color scanning, implement
color scanning of the document.
