What to do if my Ricoh 2020D - Aficio B/W Laser says 'Cannot dup. copy this size'?

If your Ricoh All in One Printer displays 'Cannot dup. copy this size', it means you've selected a paper size that's not compatible with the Duplex function. To resolve this, use one of the following paper sizes, which are compatible with the Duplex function: A3L, B4 JISL, A4KL, B5 JISKL, or A5KL.
