When a Print command is received with paper loaded in the cassette, cassette pick-up operation starts. The paper supplied from the cassette is checked for normal

feeding using the sensors provided along the paper feed path. When the paper is fed by the specified length, the multi sensor adjusts the light intensity and the head

hight, detects the paper width, and then starts printing.

During feeding, paper is fed by the cassette pick-up roller and cassette feed roller. During printing, paper is fed by the feed rollers.

In paper is fed from the cassette, the multi sensor does not detect the leading edge of paper and skewed feeding of paper.
