My Epson EcoTank has been printing yellow stripes across all pages for two weeks now, even though I've already run the print head cleaning three times. The ink is still plentiful. Is there anything else I can try before I have to take it in for repair?
don't make the mistake of just buying new ink if you're not sure that's really the problem. yellow stripes can come from a dirty printhead, but also from clogged nozzles or a defect in the color system itself.
try this: do a deep cleaning instead of just the normal cleaning. with epson that's usually done through the menu - check in the printer settings for "deep cleaning" or "maintenance". it takes longer than normal cleaning and uses more ink, but if the nozzles are really jammed it often helps better. then print a few test pages. if that doesn't work, try again after waiting an hour - sometimes it just takes time for the ink to flow through again. plus i'd check if the tank is really seated properly and if any of the tubes are kinked from the outside.
if you still get those yellow stripes even after a deep cleaning and restart, then a nozzle is probably really broken or it's a problem with the electronics. honestly in that case i'd take it in for repair, because you can't do much yourself without taking the thing apart. with ecotanks this happens a lot if you don't use them for a while, but if it doesn't get better after several attempts then usually it's game over.
If you're getting yellow stripes despite cleaning multiple times, I'd suggest you first inspect the nozzles yourself - don't just run the automatic cleaning! Take a cloth, dampen it with distilled water, and gently dab it on the nozzle plate (the side that sits on the paper). If yellow comes out, the nozzle is just clogged and you can dab gently several times until nothing comes out anymore. That often works better than the cleaning programs because they sometimes aren't strong enough to get stubborn dirt out.
A problem that a lot of people overlook: With EcoTank printers, the tubes from the ink cartridge to the print head itself can get clogged or twisted! That happens especially if the printer hasn't been used for a while or if the ink has aged. No amount of intensive head cleaning will help in that case. Check if the tubes are sitting properly and if you see any kinks or air bubbles in them. They should be tight and clear.
If none of that works and the yellow stripes stubbornly stick around, it could also be the print head itself that's the problem - but before you get it repaired, try turning the printer completely off, unplugging it, and waiting at least 30 minutes. Some systems sort of "reset" themselves and that can work wonders! Only then would I take it to a service center.
Yellow stripes after cleaning three times point to something more stubborn than just dirt. Have you tried rinsing the nozzle plate yourself with distilled water by taking out the print head and letting it soak for a couple of hours? With EcoTank models, ink circulation in the tubes can also get stuck - if there's an air bubble in there or the connection from the tank to the head is damaged, you'll get exactly these kinds of stripe patterns. Before you pack it up, I'd still check whether all the tube connections are tight and whether ink has leaked anywhere.
Before you send it in, I'd try one more thing: Check if the ink tubes themselves are clogged or if there's air in them - that happens with EcoTank pretty often and causes exactly these kinds of stripes. For that you need to take out the print head and check the tubes from the top to see if there are any bubbles in them. If there are, you can carefully push some distilled water through with a syringe, but be careful not to damage anything. If that doesn't help or you're not comfortable doing it, then a repair is probably really necessary - could also be that the print head itself is defective and not just dirty.
If the automatic cleaning didn't work three times, I'd try putting the thing in a certain position for a few hours and letting it sit - sounds crazy, but it actually helps sometimes. Some people lay the EcoTank on its side (with the print head facing down) so the ink runs into the nozzles by itself and pushes out air bubbles. About 3-4 hours minimum. It costs you nothing and is less invasive than tinkering around.
If that doesn't work either, then I'd take a look at the ink tubes myself - like the others already mentioned, this happens with EcoTank really often, that air gets in there or something clogs up. You can gently squeeze the tubes to feel whether they're still liquid or feel hard. If there's actually an air bubble stuck in there, you can try to gently massage it out. But honestly, if even that doesn't work after all these attempts, a repair shop is probably the better option than putting in more time and potentially frustration.
