Many printers have static cartridges with valves that prevent cleaning fluid from being injected. Some Epson Ecotank models (e.g. the ET-2710) make the head inaccessible (you can guess why!) and sometimes people just want a quick fix rather than buy a kit and wait for it to be delivered.
If this is you, then the video by Marrutt shows how it’s done.
- Initiate a printout (a nozzle check is fine)
- Remove the power cord while you can hear the head moving
- Lift the lid and check that the head moves back and forth freely
- Slide the head over a wad of paper towel. (Marrutt use plastic wipes to reduce the risk of lint, but I prefer paper because it’s cheaper and swells when wet, increasing the chanace of it touching the underside of the blocked head)
- Syringe 5ml of cleaning fluid near the head. Warm water works OK as well.
- Leave to stand for 30mins-1 hour
- Remove the paper towel and power the printer up
- Alternate between nozzle test and the clean cycle until the print is perfect or there is no improvement (at which point you can run the soaking procedure again)
This is a simple, gentle method that works with any printer where you can get to the head and I’d encourage you to try it before buying any cleaning fluid. The only risk is from interrupting the power to the printer but I suspect this is no worse than that of injecting fluid through the head.
I’ll finish with a clip where an R3000 was revived by injecting cleaning fluid: the only downside being that it took 45 pages of solid black print to purge the lines of fluid.
Good luck and let me know how you get on.
