Magenta head clogged on JV-133

[nashvillesigns]

Hi, i have been printing with this printer for six months. its over 2 years old. does anybody know a really good way to save a JV-130 head besides the normal methods? All my heads (8) are perfect except the magenta section. it doesn't matter what i do. the test lines are 68-73% there. this causes banding/fading with any red color in my machine when printing..
(i do have a syringe, so, could i remove the damper and "lightly push" the clogs out? i was going to preload magenta from the damper and push it through. its either that, or cleaning solution. So,i am only thinking out load, here......)
i was also told you could take some pure alcohol and with a mimaki lint cloth wipe "back to front" on the head.
soaking the heads in solution over night does nothing. i am sure there has to be a way to do this...

In any case, i am waiting for some cleaning stuff to come in tomorrow...

happy printing!
Chris

if you need something stronger just add a little acetone to your solution. also i was told by a tech if you want to contact the heads with a swab, use a very saturated swab and the motion is a very light pivoting motion, not really doing any traveling across the head.

if the head is that clogged, you should take it out of the machine and really get a good look at it.

i hate solvent printers

thanks, i will.
now after printing some small jobs, my machine no longer prints, or does test prints.
all i get is this:

error 7
voltage error
(0----)

i then have to turn off the machine.
any suggestions? i do own a double barrel shotgun.

Here's what the service manual says about the error 7:
