New bizhub 3320

Take out the paper from tray1 and switch it the other way around. to do this of course you have to move the paper guide in the tray. make sure the length guide and the width guides are fitting properly. then close tray and go back to the paper menu and see if the paper size changes. the machine automatically detects the paper size.

see page 107 of the user manual for the paper settings and setup

We have had this issue with a few of our 3320's straight out of the box. Remove tray one, press the rounded lever on the left backward and this will drop the feed rollers. Clean these rollers with alcohol or 409.
If its still not recognizing paper make sure its sitting on a flat surface (not like a dented filing cabinet)
