The problem with these is the head design and the thickness of Epson ink. This is more of a problem on the DuraBrite pigment models but the dye printers (Claria, etc.) can clog like this just as easily. The best way to fix it is a hot water or 70% alcohol and hot water injection, or removing the printhead and soaking it if you can remove it without damage. Most Epson printers get damaged by mere attempts. You should also be aware of the mess this procedure makes, so wear gloves if you do not want to get ink stains on your skin.
If you go with hot water and alcohol, here's how you do it:
- Loosen the printhead. On some models, there will be a white tab you can push to free the head up. On others you will need to put it into ink change mode, remove the cartridges and unplug the printer. The easiest way to tell is to see if the printhead comes to the center when you open the lid.
- Fold some napkins up and put them in the printer's track. You will need to make sure you do not put too many in or the head will not go there easily. The average is 3-5.
- Remove the ink cartridges from the printhead. Set these aside somewhere safe.
- Get a plastic tube and syringe that can accept this tube. Get your 70% alcohol and push it through the printhead slowly to get the dried ink out. Do this 2-3 times.
- Once you do this, push distilled water through the printhead and do this 5-6 times to make sure the alcohol is out of the printhead.
- Dry the printhead spikes with a lint-free cloth.Once you do this, run a nozzle check and see if it's clear. If not, repeat this until all of the ink comes out of the printhead. Run a nozzle check once a week to keep the ink from drying out if you do not use the printer on a regular basis.
You have one of the few Epson printers that can have the head removed without damage, but I still do not recommend this unless you are willing to risk destroying your printer. To remove the head you typically remove 2-4 screws and disconnect flat flex cables. You will then soak the printhead rather then use syringes and plastic tubing.
