Auto Calibration
Auto Calibration
Performs automatic correction when the black copies is 
off. The machine prints a test patch, the test patch is 
scanned, and the black is automatically corrected.
After the [Execute] key is tapped and a test patch is 
printed, a message appears prompting you to begin 
automatic calibration. Place the test patch on the 
document glass as shown below (so that the thin line at 
the edge of the page is to the left).
Lay copy paper (about five sheets) that is the same size 
as the test patch on top of the placed test patch, gently 
close the automatic document feeder, and touch the 
[Execute] key.
If the black is still off after performing Auto Calibration, 
repeating Auto Calibration once again may improve 
the black.
