It seems that we are making a little progress. I feel that if you wait for 24 hours, and repeat, you may get it to work. There is no point in running the cleaning cycle repeatedly as it uses a lot of ink. If you allow the printer to sit after a cleaning the new ink that has been forced in to the cleaning system may loosen the dried ink that is left, allowing the next cleaning cycle to push it out.
I have to say that it is unlikely that Epson will replace the printer after 3 years. If you had voiced displeasure with the product within the warranty period they probably would have. Any ink jet printer will have these problems if it is not used on a regular basis. Being allowed to sit unused for long periods of time is the root cause of the problem.
I do have a couple more suggestions for you. These are to be used a last resort, after all else has failed.
Methods to manually clean Epson printheads:
Please perform the suggested methods of manually cleaning the Epson print heads in the order they are listed below. They are listed in order from the easiest to the more difficult. If the first method does not completely solve the problem, then go on to the next.
METHOD ONE- MANUALLY CLEANING EPSON PRINTHEAD
When the Epson printhead is in its resting or 'off' position, the printheads are above a single or two sponges. By saturating these sponges often excess ink on the printheads will mix with the water and get sucked into the sponge when the printer is turned on. Move printhead assembly to center of printer: Start with the printer turned off. Open top of printer so you can see the printhead/cartridge assembly. On older models of Epson printers you can simply move this assembly to the left, towards the center of the printer. Newer models have a locking lever which prevents the printhead assembly from moving from the resting position. If you look closely, you should see a small, plastic (usually black or white) lever which comes up whenever the printer stops printing. The lever to which we are referring is just left of the printhead assembly. This lever can be moved forward and down easily with your finger. If you can't see the lever, then print a page with the top open. Watch for a lever that goes down when it starts printing and then goes up after it has stopped.
If there isn't an unlock lever then just run a cleaning cycle. When you hear the printhead moving back and forth, pull out the power plug. This should leave the printhead assembly in an unlocked position so you can easily move it back and forth.
With the printer off and the lever moved down as far as it will go, gently push the printhead/cartridge assembly to the right. It will only move a fraction of an inch, but you should hear a click. This is a second lock being released. The printhead assembly should now easily move to the left towards the center of the printer.
With the printhead moved, you can now see the sponges which were under the printheads. Take a syringe or eyedropper and saturate the sponge with a mixture of 50% distilled water and 50% Windex Original Window Cleaner. Fill the sponge holder as much as you can. Regular water will work, but it is the last choice. Move the printhead assembly back over the sponges ... as far to the right as it will go. Let printer sit for at least 15 minutes before turning it 'on'. You may want to leave it overnight.
Be certain the printhead assembly is as far to the right as it will go before turning the printer 'on'. Print 6 or 8 pages of dense print or graphics if it is the color which is causing the problems. If you still have clogged nozzles, then move on to the next suggestion.
METHOD 2 - Cleaning the INK DELIVERY SYSTEM TUBING
Remove ink cartridge(s) from printer. On newer models you may have to hold one of the buttons down for several seconds for the printheads to move to the center. Refer to your printer manual.
With the cartridge(s) removed you will now be able to see the small cone shaped ink tubes (ink ports) which take the ink from the cartridge to the printhead. Black has one cone and the color has three. Using a syringe with blunt needle, put a few drops of Windex or distilled water in the cone. We recommend putting water or printhead cleaner only in the cone which sends ink to the printhead causing the problems. e.g. if it is the yellow which has nozzles missing, then put water only in the yellow inkport. If you're not sure which color is which, then look at the holes in the bottom of the color cartridge. Yellow is usually the color on the far right with magenta (red) in the middle and cyan (blue) on the left.
Put the cartridge(s) back into the cartridge holder. Do nothing. Usually after a few minutes the printer will automatically return the printhead assembly to its resting position. If any water or printhead cleaner dripped into the printer, wipe it dry with a paper towel.
Print 6 or 8 pages of dense print or graphics if it is a color which is causing the problems. If you still have clogged nozzles, then move on to the next suggestion.
METHOD 3 - Clean printhead with paper towels
Fold paper towel and dampen:
Be certain the printer is turned 'off'. Tear a single sheet of paper towel in half. Fold the sheet in half several times until it is about 1/2 inch by whatever length the sheet started at. In other words, you want to fold it so it is long and skinny, not square. Open the cover of the Epson printer. Along the path which the printhead assembly travels when printing, you will see a rubber roller which moves the paper. (this is like the paper roller in a typewriter). Put the paper towel on top of this rubber roller and use tape on each end to secure it. Put a few drops of Windex mixture mentioned above or distilled water near the middle of the paper towel.
Move printhead assembly over the paper towel and let it rest on top of the damp portion of the paper towel. (See above for information on how to release the printhead assembly.)
We suggest letting the printhead sit over the paper towel for at least 15 minutes. This will soften the ink on the printhead. Move printhead assembly back to its resting position. You will probably notice that the paper towel now has one long black blob of ink on it. (There is so much excess ink on the printheads that all the colors are mixing to make black.) If you cannot clearly see individual colors, then dampen another spot on the paper towel and move the printhead back over the newly dampened spot on the paper towel. Continue repeating this until you see all the individual colors. You may have to use several pieces of folded paper towels.
Before turning the printer 'on', be certain to move the printhead back to its resting position and remove the paper towel from inside the printer. Now that all excess ink has been removed from the printheads, your clogged nozzles should be cleared. It may take several pages of dense print to get the ink flowing properly.
Please give one or more of these methods a try and let me know the results.
