Manual DADF to Scanner Calibration Note Perform this calibration procedure when replacing the scanner unit or DADF assembly. It is best to start this procedure with the scanner having just made a duplex copy, this ensures the lamps are on and ready. If the lamps need to warmup, the claibration procedure will fail due to a timeout. Manual calibration of the platen to DADF scanheads adjust grey level and margins. It matches the front of the page to the back of the page on a duplex scan/copy. You need the Scanner Calibration Page for this procedure, see "Xerox Supplies" on page 9-16 for the part number, or use the page that came with the replacement part.
