favor needed

[styckers]

just bought a dr. head cleaning machine anyone with old clogged heads for roland sg2 that are clogged and not delaminated i could use them to test this machine i will cover shipping better than just throwing them away thx in advance

 

[netsol]

did you buy a real print head doctor?

what chemistry are you going to be using?

 

[netsol]

i bought a Chinese knockoff a couple years ago

 

[styckers]

yes bought real one waiting on it to arrive

 

[netsol]

they have the best support for what chemicals you use in the unit.
it's worth a call to canada to talk to val if you run into trouble.

i find AS A RULE this whole thing is very effective if you use the unit before it is apparent you have a bad head and need to flush.
a gentle flush, periodically can be very helpful

 

[netsol]

i often will use a bottle of the flush or cleaning fluid your ink manufacturer sells

if it appears not to be working, i will add 5-10% acetone. (10% might be pushing it)

 

[styckers]

Thx for all the help will keep you updated

If the heads are already clogged, you have very little chance of recovering them with those machines. They may be helpful for very light blockages, but your printer itself can clean those just as well.

The machines have a purpose but a very limited one.
and, you don’t truly understand the limits until you own one & have destroyed a couple marginal print heads
