Im having huge problems with the magenta head its about 4weeks old, I give it a strong clean then start printing it prints great for about the first 300- 500mm then slowly jets will start dropping out & print is then no good. I checked the cap & is sealing well o-ring is sealing well & ink is getting to the head. HELP PLEASE!
Here the same problem, since 4 weeks still unsolved.
Replaced the magenta printhead, tubing, capping station and spend lot's time testing.
There is no tube leaking or somenthing similar. Problems occured after last two ink changes magenta.
After 50cm of printing magenta head losing nozzles. directly after the job is finished start a nozzle test and everythings looks fine! Not even one nozzle missing.
My opinion, something is changed with the ink, HP recently changed there ink, now they are switching back to old ink. Problem was exactly the same as we experiencing on our SEIKO 64.
Someone with i bright idea? I think we did everything possible?
