I see the DocuColor 12, 3535, 240/250 and others all advertise a "Poster Mode" in their specifications. However, there seems to be a great conspiracy against revealing what that actually does. Can someone tell me what exactly "Poster Mode" is?

What I am looking (praying) for is "banner size paper" - aka ~12"x48".

Poster mode is a copier only feature to enlarge / tile an image off the glass to multiple sheets of paper, ala poster mode.

Sorry to disappoint.
