Specifying Paper Type and Thickness Settings
If the print settings and the loaded paper that are used for a print job do not match, a mismatch error occurs.
Check and specify the paper settings before you start printing.
Before you change the settings, confirm the priority of the paper settings for printing (priority to the printer driver or to the control panel).
On the printer driver
Check the settings of paper tray and paper type on the printer driver and make sure the settings match the loaded paper.
On the control panel
Press the [Menu] key and check the settings in [Paper Size: (tray name)] in [Paper Input] and make sure the settings match the loaded paper.
