Black Channel stopped printing

[binki]

My black channel stopped printing. What options do I have to get it going again? Can I run a cleaning cart in it? Anything else?

I have done 2 head soaks so far. One for 16 hours and one for 4 hours. Still no dice.

If you have 0 nozzles then cleaning aint going to help anything.

Head is dead, fuse is popped, cable broke or something else in the ink delivery.

It was printing just fine. I did a head clean and the test print started showing less and less.

What model are you working on? Have you checked the ink cartridge to make sure it's not empty and not flagging?

I tried a different ink cart. Both had ink in them.

Just an update. I removed the capping station, flushed the drain lines that lead to the pump and reconnected everything and it got much better. I will have to probably replace the capping station but that is where we stand right now. I will do another head soak tonight and see if that improves things.

I replaced the wiper, felt and cap top with tubes and the problem is now resolved. While I was able to partially flush the drain lines, it wasn't enough. The new assembly fixed all of that.

Only a slight problem with some banding. Working on cleaning that up.

Right now C and M are printing fine, Y and K are having problems. Not sure what the next step is. Y was fine when K went out. Now Y and K are only partially getting a good test print

Here is the test print after changing the wiper, felt and cap top. The printer was working fine about 10 days ago. All of this started after a head clean. I have the white ink option but have cleaning carts in for white for the last 3 or more years.

Any thoughts here?
