Have you read this?Epson Printer Error Code:0x1404
I bought my P800 on October 25, 2015 after owning the 3800 and then the 3880 which both died. Today, December 28, 2016, my P800 showed the Printer Error Code:0x1404. I called the Epson Customer Service number at 800-463-7766 and was referred by a foreign call center to 562-276-7272 where a helpful individual named Ion told me my warranty had run out on November 22, 2016, about one month ago. After walking me through the obvious troubleshooting steps of checking for jammed paper, stuck heads, unplugging and shutting off, the P800 did not correct the error. Ion went off-line and when he came back on-line, he said the likely cause was a faulty ink pump. The next part is painful but informative. I bought a new P800. As I was moving the old P800 to my car, I dropped it and it broke into a bunch of pieces. So I went about setting up the new P800 with the ink cartridges from the old P800. Guess what? I got the same error message, 0x1404, and the new P800 would not initialize. I changed out the ink cartridges for the ones that came with the new printer and shazaam, no error message! The cause was either a faulty ink cartridge or an ink cartridge from the 3880 that I may have installed in the old P800 and that is no longer accepted by the P800.
