I have two of these machines: Epson Photo R300 printers. They have been working fine until they almost started failing to print properly. Suddenly the reds and yellows stopped printing, so I checked the ink levels and showed these cartridges (6 of them) were almost 50% filled, so then I started some head cleaning cycles to no solution; several head cleaning cycles went by and all of a sudden the cartridges started to show about 5-6% full, meaning the head cleaning cycles have in fact wasted precious usable ink. Then I tried what this guy said:http://www.bleepingcomputer.com/forums/ind...l=epson+printer
to no positive results to be seen.
I then changed into a new set of cartridges (6 new ones) and run 2 head cleaning cycles. What happened? Nothing! Then I started to search on google for: "Clogged Epron Nozzles" and there were only ads for guys selling special made liquid cleaning solutions.
Trouble is that the nozzle assembly on these printers can't be easily disassembled but I am willing to give a try if somebody could give me some advise. So hope somebody could help to end this misery; I have also lots of new cartridge sets for these, so buying a new printer is not an option right now.
