I went through two P900s... the first had paper feed issues and the front tray was jammed from day one. The second worked for most of a year before it, too, grabs several sheets and bricked, but that was after it started to spit ink blobs on the margins and images, usually on the good paper...
I'd call Epson and send them images of the damage before doing anything more.
I do know that others that have the P900 love them and the print quality is nice, but after going through two, I "downgraded" to a 3880 that I had serviced and recently got a pair of P800 printers which is what I really wanted when I ordered the P900.
The older 17-inch printers are larger, heavier, more robust and I'd say built like tanks and now I'm printing up a storm and enjoying printing with few issues.
