I just recently acquired a MAXIFY GX2020 and chose it because of the duplex printing and range of paper sizes supported. I tried auto duplex printing on a5 paper with no success, and after finally digging into the manual it seems only letter and a4 is supported for this? Yet when I looked up duplex on the Canon site, it indicated that a5 was supported? Which is correct, or what can I do to support duplex printing other sizes?
