VJ1604 maintenance station

[bsm]

Hi Guys,
I can get ink through to the waste bottle on cleans, but am getting only half a dozen nozzles firing. Is it possible that the maintenance station is gone, and why would it not push through the head but it will pump ink out on cleans?

I had this same problem on one of my mutoh printers yesterday. The small drain lines from the maintenance station were clogged with ink.This makes the head dry out as the capping station is not pulling any ink. Only way I could print was to run a cleaning cycle first.
I used cleaning solution and a syringe to clean out the 2 lines by pushing and pulling cleaning solution through the lines slowly until cleaned out. Process sounds simple but it took about 4 hours of cleaning to get it back to perfect.

No, like I said I can get ink out of the waste lines, they are clear. It is the nozzles that are not getting ink through.

Bsm what was the cause/fix?

Is capping station sealing 100%? Is rubber seal of capping station in good order? or how old is the head?

Also I pour cleaning solution through capping station on a daily basis to ensure all drainage lines are free from dried ink build up. Hope this helps.

Maintenance station is a couple months old I'm getting cross contamination in one damper after replacing all of them. It seems like I'm getting a good seal on the cap. Head is about five years old. I'm replacing the manifold next hoping its the problem. Missing a majority of nozzles.

Your head is on the maximum life time for one of these machines.
I thought the manifolds were bonded to the head on the DX5 and were non removable.
If your head is still printing fine I would be changing the head cable, dampers and a new maintenance station.
Even if the station is newish I would replace as I have had faulty ones before.

First you should attach a syringe to the clear tubes that come from the pump. if you do not have a slitter you can attach to one and pinch the other off. Try pulling ink. Do you hear any slurping sound. If so the cap is the culprit. This is one of the most common issues. Most of the time I change the complete station because there is ink all over it and the wiper slider will fail next.if you do not hear anything then you need to move to the next step.

Sorry about such a late response. The capping station was not sealing properly. It will flush ink but because there is not a good enough seal it would not get ink through the head.
