[neobruo]

Hello everyone

I have a problem in my hp 10000s. This machine start to make banding at amgenta color. Since that i have checked all ink circuit, pipes, sub tanks, primes, capings, selenoids, and all is ok. At last i send the printhead to perform a recovery at the printhead doctor machine, and the print head is ok.
I change the flat cables that connect to main pca and change the conections at main carriage!,
All the assembly parts were changed... i dont know what to do to solv the problem... anyone got more ideas?

Have you tried soaking the heads with wiper fluid and the head cleaning kit?

Thanks for the idea, but the printheads were submited to the recovery at printhead doctor. They stayed 2 days with the best clean fluids!

We have 2 9000s here. We had a similar issue with magenta and cyan. You might try replacing the O-rings at the head and the filter. We ended up replacing both heads when we exhausted all the other options.

i dont no what you really do but.....1st check airleaks aso....ok
2nd step adjust the headvoltages. you can play a little bit with +1volt aso.
if not help your Printhead is electrical damage "nozzles crap" if you manuel purge the heads can be 100% nozzle but electrical is another one !!!! after voltage gaming no better result...garbage it
