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.
