Best way to revise deflected nozzles?

[phototec]

Anyone know the best way to revise deflected nozzles, I have tried soaking the heads but no real improvement.

Roland SP-540v

Any other tips or tricks?

Thanks

Mixing a small amount of acetone with your soaking liquid can help, then do a 20-30 minute soak>hard clean>test print

I'm not sure about Roland heads, but I have had some luck pulling my heads and using a large syringe to slowly and steadily push solvent
through the heads. I will then put the heads in solvent and slowly and steadily pull solvent
through the heads.

I have also heard some people use ultrasonic jewelry cleaners with cleaning solution. [h=1][/h]

I would not pull the solvent back thru the head at all. Pushing thru with great caution.

I have two of these http://www.digiprint-supplies.com/dx4-printhead-cleaning-tool.html I have brought some heads back from the dead! Load em' up with cleaning solution (I use Solaris flush fluid for bulk systems, get it by the liter), I run some through the heads first, then block the lines, fill the head caps and cap em' overnight so they're soaking inside and out. Next morning I push the remaining flush in the syringes through into a cup and run a couple heavy cleans to fill the head back up with ink... Works wonders, but like everyone else says, push the flush through slow and easy.

Get new caps and they will fix themselves...

I know new caps help with plugged nozzles, but didn't know that would help deflected nozzles...

A deflected nozzle is a partially plugged nozzle, unless the nozzle itself has become deformed from a head strike or aggressive cleaning, or a chunk of dried ink being scraped across by the wipers.
