Switching the Page Size between A4 and Letter
You can switch the size of paper loaded on the rear tray between A4 and Letter.
This setting is useful if you usually load Letter-sized paper in the rear tray.
1. Make sure that the machine is turned on.
2. Press and hold the Stop button until the Alarm lamp flashes 10 times.
3. Release the Stop button.
The ON lamp starts flashing instead of remaining lit.
4. Press the Black button to select A4, or the Color button to select Letter.
The ON lamp stops flashing and remains lit, then the paper size is changed.
Note
• When you switch the page size to A4 or Letter, load paper of the selected size.
When the page size is set to A4, load A4 plain paper.
When the page size is set to Letter, load Letter-sized plain paper.
• This setting is retained even if the machine is turned off.
