Printer Gamma Correction - Ricoh B230 Training Program

The gamma curves for C, M, Y, and K are not equal.
If this causes copy quality problems, the user can do the ACC
procedure.
A gamma curve describes the relation between the image density of the original
and that of the copy. The relationship is not linear: doubling the ID of an original
does not double the ID of the copy.
The printer characteristics are much more variable than the scanner. Therefore,
the printer gamma needs recalibration and adjustment from time to time. This is
done using the ACC procedure.
Each color has separate gamma curves for photo mode and letter mode, and for
copier mode and printer mode.
The gamma curves for C, M, Y, and Bk toner should be identical, but they are not.
ACC (Auto color Calibration) can be used to correct for this if copy quality is
drifting too far. This is done by the customer.
If this does not work, you can do the printer gamma adjustment.
