What to do if my Ricoh All in One Printer says 'Cannot dup. copy this size'?
- CCameron BennettAug 12, 2025
If your Ricoh All in One Printer displays 'Cannot dup. copy this size,' it means you've selected a paper size incompatible with the duplex function. To resolve this, use paper sizes 11"×17"L, 81/2"×14" L, or 81/2"×11"KL, as these are compatible with the Duplex function.
