        If you have Service handbook there should be Image Quality Adjustment (Copying Function). Basically you print internal pattern/chart and put it onto the glass, input appropriate code, then scanner reads the chart automatically and performs automatic adjustment.

            Turn on machine while holding 0+5, Select the A4/LT drawer
            Input 4 and then press FAX button. The machine should produce color/black pattern.
            If not, what happens? Is there any message?
