Hi. I have tried several suggested solutions to my Epson 7890 not printing from the magenta channels. There are air in the tubes, which I now am certain is part of the problem.
What I have tried:
- Several cleaning attempts, both normal and power from the printer itself
- Deep cleaning overnight with cleaning solution, which resulted in six perfect colors at nozzle check, but no magentas
- Initial fill, six times wasting a lot of ink
I got a reply from mr Walker where he said it was a head delamination, but unfortunately at the time I had explained the problem wrong, so I will try again, since I made that mistake.
There is no ink flowing from the magentas. No magenta ink flows to the waste tank, only all other types of ink. The printer seems to think the fluid is flowing, because it programs the chip to go towards empty for every initial fill, but I have confirmed by physical opening that at least two cartridges are just as full as they were when new. I now can clearly see large air bubbles in the tube, and while initial filling, the air bubbles are not moving. It is also making a strange sound, like it is creating some kind of vacuum somewhere, it sounds like it’s trying to push air through a very tiny opening.
So, in short:
-Perfect nozzle check, exept for absolutely nothing on both magenta channels
-Printer has only printed 148 pages, but were not in use for over a year before I cleaned it. (All channels were clogged at the time)
- Vacuum noise while initial filling. Most times it ends it before 100%, sometimes at 55%, other times about 88%.
- Now it says “clogged nozzle detected, cleaning recommended”, but I am pretty sure there are no normal clog issues any longer. I think it it either the head, the pump or something bigger in the tubes that stops the ink from flowing from the cartridge.
Any help is very much appreciated. This printer is very close to being trashed, although it does print very nice using only black ink atm.
