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 [System Settings], [Tray Paper Settings], and then [Next]. Check the settings of the tray you use (bypass tray, tray 1, tray 2, tray 3 and tray 4) and make sure [Paper Type] and [Paper Thickness] match the loaded paper.
If [Display Bypass Tray Paper Settings Assist] in [Tray Paper Settings] of [System Settings] is enabled, the paper type currently specified appears on the control panel when you load paper on the bypass tray. Make sure the settings match the type of the paper you load on the bypass tray.
