What does 'Paper Size Mismatch Paper of the selected paper size is not supported for the [Duplex] feature' mean on Ricoh Aficio SP 3410DN Printer?
- CChris ClarkSep 12, 2025
If your Ricoh Printer displays 'Paper Size Mismatch Paper of the selected paper size is not supported for the [Duplex] feature', it means 2-sided printing could not be performed because the tray does not contain the valid size paper, which are A4, Letter or Legal. Specify the tray containing the A4, Letter or Legal size paper in the printer driver setting.
