I've been having some issues with my Epson Stylus SX400 inkjet Printer lately. I'm not using Epson ink but some cheap ink I bought on ebay.

Recently my printer stopped working, it was just giving me blank pages. Not a single color worked. Sometimes I wonder if these printers aren't programmed to fail if one puts non-Epson ink in them.

Well after reading a bunch about how to unclog the printer I was ready to trash it and find a new one since I was not going to open the printer up and try to mess around with the guts.

So I tried the following to unclog it and it worked.

First I made an unclogging solution with 1 part window cleaner, 1 part distilled water and 1 part alcohol (medical type). I mixed that all together into a home made ink-jet unclogging solution after reading various stuff on the internet.

Then I took out the ink cartridges one by one and with a syringe I put a lot of this stuff on the ink tubes and in the ink tubes (the ones that take the ink from the cartridge - not the heads). I did this for every color ink.

Then I ran the cleaning program and voila. Almost works perfect now, at least it prints whereas before it didn't.

Of course this isn't as good as a professional repair, but it surely is cheaper than buying a new printer.

Let me know if it works for you too.
