Epson P-800 Paper is fed crooked. I've received 5 replacements from Epson.

[Joe Morper]

I have a P-800. After printing about 1000 or so sheets using the auto sheet feeder, the feeder starts drawing the paper in crooked. I contacted Epson and they were kind enough to send me a replacement printer. Unfortunately, this very same problem has happened again and again and Epson just sends me another replacement printer. So far, Epson has sent me 4 replacements. I am now waiting for the 5th replacement to arrive. (the 4th was defective right out of the box with a different issue.) Epson tells me that after 1 year the warranty is up and I will have to pay for repair. I thought that "warranty" meant that Epson would repair the printer. All Epson does is send me replacements which break after a few weeks. Sorry for the rant but the breakdown always happens in the middle of a print job. Any idea why the paper is drawn in crooked? I'm using Epson paper and do the roller cleaning every 250 sheets. thank you
