I can confirm that the problem was solved aafter I celaned the blockage and the remaining drops of ink were direct result of my actions. I was disconnecting the power cable to wipe spilled ink. And I think disconnecting the cable while the printer was in action was causing the spill... I keep...

I think the video will be enough for me - I was probably fighting that problem for a very long time, blaming cartridges. For future reference: - back pressure from clogged waste ink lines can push back ink in the head, so when you replace one ink another one looses priming. - foam in the ink...

Ink stained Fingers, thank you very much! Problem solved! :-D

30 cm of the wire pushed in and whatever was there yelded! I hope it was blockage not some fancy check valve :-)

I managed to push in 20 cm (8 inches) of flexible copper wire inside. Still no change, Edit: where the tube normally goes? Straight into the waste ink pads?

After removing the bottom gray tube I could suck water from the pad and generate foam as well. So that part doesn't have blockage. Possibly blockage on the other side wherever the tube goes. Edit: the other side (pad-pump-external access point-"other side") is blocked. I tried...

I have much better access now - everything from the top removed. Should I try some syringe operation? All photos from the same side.

Thank you! i have service manual (average quality, to be honest), so I'll try to get to the tubes from the front. I managed to get my hand "under the bonnet" in the tubes area and it came back with plenty of ink - you might be right about the blockage and probably there is a side leak. i'll post...

I have R2000 for 5+ years, use Marrutt refillable cartridges - the ones with blue cradle and Marrutt ink. I got the blue cradle cartridges recently - the older ones (Marrutt as well) were showing some problems. I couldn't get the check pattern fully filled, so I decided to use magic bullet...

The are vents are plugged by the original rubber plugs. I'm suppose to remove them?? :eek:

After refilling another colour the outlet channel [1] on red became empty despite of the cartridge being 50% full:

OK, I think I know what is the problem and how a perfect nozzle check on i.e red colour check can become really bad after refilling another colour. The problem seems to lie in the design of cartridge - even if the cardridge is 50% full the vertical channel going to the outlet can become empty if...

I'm fairly sure my problem is related to cartridge priming. I did upside-down/side priming and I'm back to almost perfect nozzle check. The top volume over metal mesh is now half-full after the upside/down side priming. It was almost empty before. Definitely sucking in some ink in normal...

Most of the colours have perfect nozzle check now, but not all, so it's not fully resolved. I strongly suggest to do some purge print and then leave the printer over night to settle. I'm considering CISS to avoid removing the cartridges completely.

That's how it looks on fedora linux. "Unknown" is Gloss Optimiser

Yes, I can see all cartridges levels, except I have marrutt cartridges and the software doesn't seem to match the reality :) I think that the linux epson-printer-utility is the same or very similar as on mac os. Is it the same WicReset that you're writing about? http://www.wic.support/ Looks...

Thanks for the suggestions! I use epson-printer-utility for linux to clean the head or do nozzle check. I think the printer somehow developed air bubbles in the ink lines, but I'm not sure how that happened.

I have epson R2000 for probably last 2 years. I use marrutt refillable cartridges with marrutt ink. The printer is not used very often and I used to have problems due lack of knowledge how to prime marrutt refillabe cartridges. Recently the printer kept perfect nozzle check, so I decided to...
