Slightly off topic, but most people have heard of someone having to replace printer cartridge heads (or even the entire printer) because ink has dried over the nozzles, clogging them.

Reported on Lifehacker.com, TheWVb has suggested soaking the base of the printer heads in WD-40 to loosen the ink.

I wonder whether this would be a possibility for Epson printers. A friend once forgot to turn his printer off before going on holiday and had to buy a new a printer. Sadly it was an A3 printer, an expensive mistake. I don't know if it is possible to remove the print heads on Epson printers without special tools.

It seems a good idea if the only alternative is to bin the heads/printer, but I wouldn't recommend this as regular
