Loading paper and specialty media
Squeeze and then slide the length guide tab to the correct position for the size of the paper you are loading.
For some paper sizes like letter, legal, and A4, squeeze and slide the length guide tab backward to
accommodate their length.
If you are loading A6-size paper in the standard tray, then squeeze and then slide the length guide tab
toward the center of the tray to the A6‑size position.
Make sure the width and length guides are aligned with the paper size indicators on the bottom of the tray.
