L26500 Yellow printhead keeps clogging

[Signmeup_DK]

Hi

Hope you can help.
My HP L26500 just ran out of garantie after 13 month. and now of curse i get a major problem :|
Both yellow/black printheads keep clogging up after 2-4 meters of printing.
I've change the printheads 3 times now, i've cleaned them manually lots of times.
I've tried to enable HP extra printhead cleaning without much luck.
All maintenence is done.

I'm printing on Oracal 3551 with 8 passes normally the quality is fine for the the kind of jobs.

Any clue?

I once had a problem with magenta print heads failing repeatedly but then I got a firmware update, which I think cured the problem. Check to see if you are running the latest firmware. The only other suggestion I can offer is that whenever you install print heads or ink cartridges on HP Latex printers, you should shake, shake, shake them up before installing, that will help to keep things problem free.

Is your printhead cleaning kit working properly?

Also, if it just happened, you might have a bad ink cartridge.

PH Cleaning kit running OK
I've made a firmware update now.
The problems has startet suddenly and i just change the yellow inkcartridge.
Hope that firmware and new ink can do the trick....

Thanks!

Firmware and new ink didn't do.
Knowing i resently changed the PH cleaning kit and the fact that it said 30% used i didn't look with my own eyes.
The picture shows what i found and i do hope replacing it solves my problem.
Man that could have saved me so much money and time if i just looked instead of relying on what the software told me......

Thank you so much for pointing it out otherwise i would not have checked!

(Can't upload the picture, it's tottaly smeared in ink, a wonder it was only yellow and black that caused trouble)
