We do not currently offer an auto-feed mechanism for AxiDraw. We have, however, seen quite a few cases where people are using them.
Some are home-built mechanisms — complex and special-purpose. Some others are as simple as a cheap inkjet printer set in front of the AxiDraw, to “print” a blank page before printing each page with the AxiDraw.
More commonly, though, people use existing paper handling tools. Print shops have tools to move paper from point A to point B, and the print shops that are using our machines use standard paper handling tools to put material in front of them.
