Copier Mode Adjustment
Overview
This procedure shows how to adjust the printer gamma by SP mode manually after the ACC
(Automatic Color Calibration) has been performed. Adjustment should be performed only in the
'Offset' part of the screen, and not in the 'Option' part of the screen. Adjustable modes are "Text
mode", "Photo mode", "B&W text mode" and "B&W photo mode".
1. Perform ACC in copier mode with User Tools.
2. Take a copy of a C-4 test chart in the mode which you need to adjust.
