stuck head? need help!

Greetings all! Been a lurker for some time and have used your site as a reference for maintenance for our jv3-75 spII.
Originally I was a software designer at the company but have inherited this responsibility.
The printer was not used for some time, and my predecessor didn’t do a very good job maintaining the cleaning on the equipment, your site has helped with that a lot.

My current problem, that is turning into a week long emergency is my black head stopped working. It doesn’t seem to print anything on a test draw even.

I’ve replaced the dampers, primed the lines up to the dampers using the syringe method, we have tested the pump by switching the pumps around, and ran many nozzle washes and head washes. We went as far as running cleaning solution through the lines down the pump from the capping station (I think that’s what its called) where the four heads rest and the pump and waste is taken. The solution went through he line no problem.
We seem to have ink up until the heads, through the new dampers, but its like the head for black is closed shut.

Any further suggestions? I’m desperate!

i rock a jv3-160, but it sounds like you've run a solid course of narrowing down your options.
...try using a syringe full of printer cleaning solution through the damper while its connected to the head (also look at the damper screen when it clears up for obstructions). Push solution through at <1cc/second (slow, as your printer would draw ink normally) and then push ink through afterwards to re-"prime" the head.
then run a test print.

*careful not to drip ink/solution on electrical/working parts as well.

You can try what Mikepro said but I have a JV3 160 and had a brand new head work great for 3 or 4 days then half the test draw pattern went out then a few hours later that whole side of the head was gone. It did pretty much what your saying yours is doing. Everything seamed to work it just would not print I could pull ink through the head but no print. Sorry to say but I think your going to need a new head.
