See below for the correct correspondence between paper settings made on the printer driver or on the printer.
For copying, make the copy paper settings to match the rear tray paper information set on the printer.
If the paper source is set to automatically switch and the print or copy paper settings do not match the rear tray paper information set on the printer, as shown below, a message appears on the printer's LCD.
What to Do
Press the printer's OK button to display the screen below.
Use the buttons to select the appropriate action, then press the printer's OK button.

Select this option to print or copy onto the paper in the rear tray without changing the paper settings.

-
Replace the paper
-
Select this option to print or copy after changing the paper in the rear tray.
For example, if the paper setting specified on the printer driver is A5, and the rear tray paper information is set to A4, change the paper in the rear tray to A5 paper and proceed with printing.
Once you have closed the feed slot cover after changing the paper, the screen for setting the rear tray paper information appears. Set paper information for the paper in the rear tray.

Cancels printing or copying.
Select this option when you want to change the paper settings. Change the paper settings and retry printing or copying.
You can suppress the misprint prevention message from the operation panel of the printer, a Windows PC, or a Mac™. When you suppress the message, the printer uses the paper settings for printing or copying onto the paper in the rear tray regardless of whether or not the paper matches these settings.
