Check the magenta damper for air leak around the o-ring. No M in the nozzle check?

Once you replaced all those parts did you use a syringe to start getting the ink through the line? Try doing it at the dampers first then if you have to, do it on the line below the capping station, do it when the head is sealed up to the capping station. PM me if you want and I'll give my cell number. I might be able to help.

yes i did use a syringe to pull ink ... started at the tubes from the pumps then realized several dampers were not filling... so i pulled it to the dampers. removed the hose from damper and pulled it.

so all dampers have ink about half full. if i pull from pump waste tube sides .. the blk and magenta are on the same tube, so i can't really tell if i'm pulling magenta. could it be a fuse? blk streaks sometimes on some test prints but no magenta at all?

 

[bayshorecreations]

If it were a fuse you would be missing 3 colors when you print a test strip.
Im not sure where to tell you to look from here. If the mag damper has ink in it.
Make sure that nothing is blocking or broken where the ink goes from the damper to the print head. From what I understand the little cone shaped thing on the print head that the damper sits on is very easy to break so check that also.

Listen to Jackpine...

nozzle check no mag and blk is gone now too have cyan yellow lt cyan and lt magenta .... i retightened the brass nuts over the o rings and some mag and blk are coming back

 

[luggnut]

alright checked the seal to the best of my knowledge but didn't seem to help... put in the old damper. pulled ink and cleaned got this first print in the pic with a streaky magenta.... pulled again it got worse pulled again... and then no magenta. after these prints i pulled ink and lost the cyan. its like it gets worse after i pull ink some of the time?

 

[luggnut]

i'm going home!!! it looks like i can pull thru with the syringe because there is a stain of the magenta on the top of capping station pad. i also tried the soak thing and there was a magenta stain there as well on the rag. and with 1 hour soak rewetting rag every 15-20min it seemed to wick all the ink out of the dampers including the magenta. but when i nozzle check there are only a few lines of magenta if any and on test there is no magenta. its like its at the damper ...i can pull it and it wicks out in the soaking rag .. but the head won't fire it out?

help

update i took a piece of tube and closed off the blk and cyan nipples .. and then pulled ink after the pump. pulled magenta a lot of it.... did a test print and the space for magenta still blank but print magenta instead of blk. did a cleaning and got all colors back but magenta? looked at top of capping station and it looks like its pulling all the colors including magenta. its just won't print magenta. the first pic is with the dampers off of the blk and cyan and the tube attached to the nipples on the head. the second is the capping station after pulling with the cyan and blk blocked... the 3rd is the first test after the magenta was pulled and the test print after one cleaning. the last is the capping station after a few cleanings ... it looks like its pulling all colors

monday bump

Is it possible that the head is bad? I don't know if just one color can go out on a head like that. Maybe someone else knows.

MacDaddy, doesn't the damper in his picture look too full?


Lug, I had that problem a few weeks back, I found the damper wasn't 100% seated on the print head nipple. You might try pulling it off for a minute and see if it drips any ink. If it does, then I think it is a air leak in the line somewhere.

If not, reinstall it, do a ink fill, and let it set a 1/2 hour before trying to print.

bradster... where would i look for the ink drip? out og the bottom of the head? or the magenta feed line?

 

[luggnut]

on an nozzle check after cleaning i have all back except for a few magenta nozzles.... but every nozzle check its different ones that are missing from the magenta? like some are good one minute bad the next....

I'm thinking if you lift the damper, and it drips from the bottom of the damper that plugs onto the print head, then you are losing your vacuum, thus a air leak in the line.

Given your second post above, I'm really thinking this is the case, but could be wrong.

I think you are not getting much ink from the damper to the print head because you are sucking air.

Did you pull the damper off and reseat it?

Post up a pic of the nozzel checks that keep changing.

 

[luggnut]

i'll get you a pic of the nozzle check tomorrow... and test that damper dripping.

 

[luggnut]
