sc 540 converted to cmykog has clogged head

[luggnut]

i am working with an older roland sc540 that has been convert to bulk megaink cmykog... the magenta head is not firing all nozzles.

i have done a head soak on a mutoh falcon before . i soaked a lint free rag in cleaning solution and then placed it over the capping station then pulled the head over and let it sit.

can i do this with this roland or is there a better way to get the nozzles back?

hook a 6-9" tube to syringe, pull cleaning solution into syringe, connect to head nozzle, place paper towel under head with enought room to observe with a flash light, push solution throught untill you see all the heads open up.

i do this all the time.

so you remove the damper and connect there? then push cleaning fluid thru?

Yes!

Is there any danger of damaging a head if you push the solution too quickly or with too much force?

 

[tomence]

Of course there is gonna be a damage if you force it.

^ I guess the way I should have phrased the question is, How much pressure is needed?

 

[ddarlak]

i have pushed as hard as can and havnt damaged a head.

i have been doing this type of head recovery for at least 6 years, you have no worries.

matter of fact, you'll be impressed at how long you can keep a head running.....

I messed up one head before started leaking from all over. So i guess you can mess up a head.

ddarlak and tomence,
What size tubing do you use when you connect the syringe to the head nozzle? Ink tube is too small. I tried pump tube also, but it didn't fit well, either. It was on the small side. I put it on top of the nozzle, but the cleaning solution more or less ran into the head instead of being pumped in.

ddarlak, i have also tried this method, but why is it that sometimes, when some of the nozzles are clogged, cleaning solution would leak from the other "nipple" while i push through the other?

thanks!
