Advice needed on VP540 print head recovery?
Has anyone had the heads recovered and put them back to work with any sucess.? I am thinking of the EpsonDX4heads.
We made the mistake of not cleaning up a leak by the dampers and this took out the Cyan head because of contamination to the PCBs.
One head has improved after taking off Inktec inks.good business for all this week! :lol1:

Hi there
I know once taken out if not left to soak in the cleaning solution once dry they cant be used again – but also they say there is a machine that vibrates and you put the head in it sometimes you can ! I wouldn’t do it or risk it. -
I’ve never used one, but I have heard the results aren’t particularly good. Have you tried flushing the head with a syringe?

I’ve had success with this, I had a fully blocked cyan head. All I done was I went to maplin and bought a cheap ultrasonic cleaner for about 30quid. When i got back i never fully put the printhead in, just the bottom of the printhead where the ink fires out. What I done was I attached a syringe to it and put a little pressure on it until all the blocked ink started to breakup with the ultrasonic waves in the cleaning solution. I done this approx 7 times on each side with forward and reverse pressure.
After you see it firing at best with the cleaning solution when finished always put it in 70+ isopropyl alcohol to clean the full head including pcb. Allow this to dry for at least 48 hours, then bobs your uncle,
Put it back in the machine and recalabrate then it’s off and running again.
But do this at your own risk, as a new head is only approx 480quid from digiprint. but if you either don’t allow it enough time to dry once soaking in isopropyl alcohol or leave alot of residue from the cleaning solution, you will short head board and thats a grand each time…. I should know I’ve spent nearly 4k on the things.
