Tone Curve Adjustment
After prolonged use, or from the effects of surrounding temperature or humidity, the density of printed images may differ
from the original. If that is the case, use this function to ensure consistency in density between the printed image and the
original. If calibration does not improve the tones, perform this adjustment.
A total of 3 pattern pages (No. 1 to 3) are printed during adjustment in [Copy/Print (600dpi)]. Also, in [Print (1200dpi)], 1
pattern page (No. 1) is printed out. The printed patterns are read sequentially during the adjustment.
When correct toner overlapping is not ensured even after performing calibration, refer to the following:
