If you register the paper size and type on the screen displayed when you insert the paper cassette, the printer informs you when the registered information and print settings differ. This prevents you from wasting paper and ink by making sure you are not printing on the wrong paper size or printing in the wrong color due to using settings that do not match the paper type.
If displayed paper size and type differ from the loaded paper, select the item to change. If the settings match the loaded paper, close the screen.
You can make settings easily by registering frequently used combinations of paper size and type as a favorite. You can make paper settings just by selecting the registered preset. To register a preset, select Favorite Paper Settings, select > on the next screen and then specify the paper size and paper type.
The paper setting screen is not displayed if you have disabled Paper Configuration in the following menus. In this situation, you cannot print from an iPhone, iPad, or iPod touch using AirPrint.
