Replaced the dampers now what? (No Cyan)

What printer are you working on?

 

Have you tried connecting a syringe to the cyan damper(s) and pulling ink through the lines?

 

This is what I was going to suggest. Pull ink from the line below the carriage rest but before the lines get through the pumps. Use a syringe, don't pull to terribley hard but give it time after you pull to allow for the vaccum to even out.

 

I was having this same problem with a JV3-160SP recently. Changed the damper with no improvement. Turned out it was the capping station not getting a good seat on the head, replaced that and haven't had a problem since.

 

I was talking about lifting the damper out of the head. Connect a tube from the syringe to the bottom of the damper, where it connects to the head. Slowly and gently pull ink to fill the damper. When it is half full, connect it to the head.

If you're still getting air in the lines after that, check the cap or the lines between the cap and pump.

 

You'll want to detach the damper from the print head and draw from the bottom of the damper. You can also connect a syringe to the tube that goes to the waste tank and draw with the print head seated over the capping station. Your not going to damage the print head as long as you go easy.

 

when pulling the dampers, make sure you pull straight up, don't wiggle or rock it, and don't twist it side to side, the manifold that sits on top of the head is made of plastic and can crack with little warning, if that happens, you have to replace the manifold, which means pulling the head.

So just be careful.

 

Just had the dampers changed on our Mimaki, some of our ink wasn't firing either. Our capping station was also replaced so it doesn't sound like too bad of an idea for you to do as well. The general maitenance to keep the printer working clean.

 

I found that trying to pull ink, with a syringe, directly from the damper is too risky. I've ruined many a damper trying that. I have found great success in doing a suction from the lines below the capping station.

Another way to tell if you need a new capping station is to do the suction from below the capping station back by the pump. have someone else stand by the front of the printer and put their ear down to where the carriage sits on the station. When doing the pumping, if the person with the ear to the station can hear a hissing sound or the sound of air moving through a tight seal - thats a solid indicator that the capping seal around that particular head is bad.

No sense in replacing parts unless you know for sure they are bad - although the capping station is one of those parts they recomend replacing at least once a year.

 

Well if the capping station is fine, you should still be able to pull ink from the line below the capping station, but before the pumping unit, until ink starts to fill the syringe. This will pull ink through the lines above the dampers, fill the dampers and fill the head into the capping station and down torward the line.

If you're still not getting anything, you may have a clog somewhere between the ink cartridge and carriage. This is more complicated and I personally have never had to address this issue. It was only suggested to me as a possible problem when I was having problems. Luckily for me it wasn't that. Hmmmm...I'm not sure what else to say.

 

Or there might be a small fracture of the head connector.very common problen when changing very old dampers..

 

printer back up n' running is good news for your "1337" post!
(that's "leet" or "elite" for you non-nerdy video gamers out there)
good to hear!

might be looking into a new pump soon, myself, as my cyan "valve" randomly doesn't close making the fluid just drain out when I do nozzle washes (and worries me that eventually might stop working/drawing ink through the capping station)
