Hi Alan, You have a good memory. I was the one who posted that. The information was given to me by the repair shop within the Apple dealer I had bought some computer gear from. I use this remedy on my Epson 1520 with regular ink cartridges. I'm not sure what country you are in, but I buy a small bottle of "Professional Tape Head Cleaner" (in reference to music cassette tape heads) from the local Radio Shack store, and use it with cotton swabs (Q-Tip Swabs).
It's amazingly simple. Remove the ink cartridges that you have in the printer. The place there the cartridges were seated is where I clean. There is nothing to take apart. If there is a great deal of ink dried in that area, I will let a few drops of the cleaner sit and do its work for a few moments. Otherwise, I just keep dipping clean cotton swabs in the liquid and rubbing it in the spot where the cartridges get seated until it comes out virtually clean. (Might take a while depending how inky yours is)
Replace the cartridges and run a cleaning cycle and a test print through the utilities and see how it looks. Print a small test print and see how things look. If need be, repeat the process, but I generally don't need to with mine. I do this periodically to avoid heavy cleanings.
I've also tried the "cleaning heads" sold by Ink4Art, but they don't seem to do a good job for me on heavy ink debris. I do love their ink though, and find it to be about 1/4 to 1/5 of what I pay for OEM Epson cartridges. I buy their products all the time.

Do remember to turn off your printer when you are done with it. That does help avoid ink leakages. I was told by the Ink4Art people that the only people who should leave their printers on all day long are businesses that run their printers constantly, other people should turn theirs off when not used.
If you need any clarification, feel free to ask. I hope this works out for you.
Best, Lynn
