This is a test-print 10 x 15 cm printed after Nozzle Checks, new refilled cartridges with mixed dye-ink from different suppliers. Scan is done with the same printer - MG7550

Case update.
During normal printing (plain paper, non OEM ink) magenta stops (cartridge NOT empty).

Cleaning cycle, cleaning with formula ( 2 times 12 h) and then cleaning cycle. Nozzle check after cleaning.

One more cleaning cycle (spots in magenta). Nozzle check after cleaning.

Next nozle (4rd)check is back to top (no magenta).

I can get magenta back by pushing tap water through the magenta inlet, but only for a short while. After about 50 prints no magenta again (cartridge change makes no inprovement).
Currently printing after pressing formula through magenta inlet.

What keeps stopping/clogging magenta?

Get yourself a new Magenta cart, I’d also suggest you buy better quality inks, the current carts are useless and nothing but trouble…
Had the same problem with PGBK and printhead needed soaking for additional 48hours.....
And soaking is also a waste of time..

Do I understand you correctly - the problem does not exist with OEM ink?
Do you have a suggestion for quality ink supplier (cheaper than OEM, 17 EUR)?
I've tried two different danish suppliers (china ink).

Whichever inks you are using are just not working properly, try some of the German compatible ink suppliers.. I don’t know if you can get 123ink.nl ink in Denmark, because they have very good compatible inks, I use 123ink.ie inks myself..

Most if not all your problems stem from poor quality inks and cartridges, and it has nothing whatsoever to do with your print head ..Despite the information supplied to you wrongly earlier..

You will get trouble with OEM ink too........and printhead failure....it is only a matter of time and if you print or not.

I hate to put a dampener on your statement but, you don’t get trouble when using OEM inks or premature head failure and printing regular does extend the life of the print head, so everything you wrote is totally rubbish..

That is ok.
I have experienced what I described and others may have other experience......only time will tell.

Many here have experienced what I’ve described and have overcome their problems by purchasing good quality cartridges, again printing with OEM ink helps prolong a print head. Ah come on, how many times now have we had to correct you, and if the advice given here is that hard for you to understand then go elsewhere, you won’t be missed…:smack
