I bought a used C84 and some EZ inks a while back.  I didn't have time
to play with it for a long time and it just sat on the floor.  A
couple of weeks ago I hooked it up and ran a nozzle test.  There were
a bunch of problems, so I've been working my way through a combination
of cleaning cycles, test images, and patient waiting to see if they'll
work their way loose.

I've given up and am exploring my next step.  On my 1160 I can put a
little windex on the cleaning/parking pad, and/or sop extra ink up
from the pad with an absorbent wipe.

Is there a "procedure of last resort" for the C84?
