Gamma Adjustment
• Clean and/or replace related parts first to solve color quality problems. Do these procedures if
adjustments are necessary.
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.
