*1: Media sensor correction
This operation adjusts the correction value of the media sensor, installed in the sheet feeder unit, to the

ass'y is replaced, and values are automatically determined via use of calibration media kit (QY9-0064: 10
sheet of reference plain paper and one sheet of reference white PET paper).
