I replaced print head, ink lines, dampners. Print head cable.. I have installed CMYK in sealed cartridges .. I have the white channels filled with sealed cleaning solution.. When I do a print purge.. Every channel C...M...Y..K...W...W...W.. Except THE LAST ONE will not spray.. Im waiting to install white ink when I can get all the channels to spray fluid.. I've replaced the dampness with 2 new ones.. I've used different cleaning solution cartridges..no luck.. We're am I going wrong.. What would cause the fluid to no hold pressure.. I flush the last channel to make sure heads not clogged .. It's fine.. For what ever reasons it won't hold ink pressure.. This leads me to believe dampNer.. I'm at a loss.. Please help..

I mainly print CMYK.. but I want the ability to do white.. I appreciate any Input

Dampeners. Replaced. It's a good idea to make dampener replacement apart of the monthly maintence

In the past when I have lost one of the white lines I have still been able to get a good white under base by going to Super fine for the white under base in the quality tab in EK Print.

Have you ever had a problem with any lines not flowing ink? In my case it is the Magenta and the Yellow. I can manually draw fluid through the dampers, but the lines will not prime or stay primed when I try to charge with ink. All other lines are flowing fine. Any help would be great.

I have found several cases where I had bad ink and cleaner cartridges that would not flow ink (after I had been advised to change print head dampers.....)....but sounds like you might have already switched the cartridges....once I changed cartridges it seemed to take quite a few print purges to get the cleaning fluid back to the head once I installed the new cartidge....

Try cleaning the little needles that pierce the cartridge, and cleaning the posts the dampers plug into on the printer. You can use a piece of E string from a guitar to clean the hole in the needle at the cartridge end. You can also GENTLY try to pull ink from the head using a syringe. Pull lightly don't push!

I have a Sprint as well and have had this problem before. It sounds like an air leak to me, especially if you are losing pressure. It the printer is left over night or several hours for that matter and the white lines have receded from the dampers, it's an air leak. Check all the small o-rings (I know, it's a pain). Very good suggestion about checking the needles that go into the cartridges. If that doesn't work, go back to school and become an accountant. They seem to do pretty well. I would suggest an attorney as well but there's already to many of those.
