*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).
