Hello,
So, last week I used the machine and everything was perfect. After that job I cleaned the machine like normally do and today (Monday) before I started the work I did a print test to see if everything was ok and the yellow is missing.
It is really strange why the yellow is missing completely, nothing is printed and is the only color in this situation.
The cartridges did not expired;
I perform the cleaning after each job;
I did a medium and powerful cleaning after the test print and it's still the same.
Any idea?

Re: Yellow does not print
Do a manual clean, just to check that nothing is on the print head.

Re: Yellow does not print
Funnily enough, 2 weeks ago I had the same issue. Most yellow nozzles were missing, and different ones came back each clean. Got an engineer out, and he diagnosed a dodgy damper (2 years old) which had black ink in it. He wasn't quite sure how or why, and he had never seen it before. Luckily he did a lot of tests etc and managed to get the head back to condition.

Re: Yellow does not print
Replaced the damper was the hardware, but it could easily of been a knackered head.... He also did numerous cleans etc of just the yellow channel
