Just to put things into perspective, the pump cap assembly, cleaner & flushing units usually runs around $250-$300 for each of our 7800's. The rest is labor and travel. I don't have the time yet to try it out on my own (LOL) but this just might help you and others out there like us; it's a service manual for various Epson printers and includes what the error code means and solution.

So far, this manual is batting 1000 for the 3 last issues we've had since I found it. Too bad they didn't embed the fonts.
