Designjet 110 + 100 ink streaking

[alexandermac50]

Hi all,

I currently run 2 designjets (110plus + 100plus) and I use OCP inks in a continuous ink system. The problem I am having is that after fitting new printer heads the printer starts banding after 10 or so poster prints. I came to the conclusion that it could be the ink so when I insert original HP printer ink cartridges back into the printers and do a few prints to draw the ink in to the heads the banding disappears. Would adding some distilled water to the OCP ink to give it a larger dot gain help solve this?

Do you have air in the ciss tubes near the cartridges? Maybe raising the ciss unit a bit would help. Try raising it gradually (1 cm at a time) then do 1-2 head cleanings then try to print. You have to reach an equilibrium for the ciss to work properly. If the ciss is too high you will flood the heads, if it's too low you will starve the heads (this is your situation now).
