*1: Media sensor correction
This operation adjusts the correction value of the media sensor, installed in the sheet feeder unit, to the
EEPROM of the logic board ass’y. The adjustment is required when the sheet feeder unit or the logic board
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).
*2: Red screws of paper feed motor
The red screws securing the paper feed motor may be loosened only at replacement of the paper feed motor
unit.
