8.4.2  Printout of Scanning Compensation Data (Function code 05) 

„

 Function 

The machine 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  
because at the start of scanning operation, the equipment initializes white and black level  
data and takes in the scanning compensation reference data. 

(1) MFC7420/7820N 

Press the 

0

 and
