Summary
To adjust the printer gamma:
• Select the print mode you want to calibrate
• Print a color calibration test sheet
• Make the gradation scales on the printout smooth from the lowest to the
highest density. Adjust the CMY gradation scale at the top of the chart by
balancing the density of the C, M, and Y gradation scales – the CMY gray
scale should change smoothly from minimum to maximum. There should be
no coloration.
