Hi, Mike. What I do in stubborn cases is to saturate the landing pads
with original formula Windex (blue, with ammonia). To get full access to
the pads, turn the printer on, then pull the power plug while the head
assembly is moving back and forth on the left side of the printer. This
allows you to move the head assembly freely.
I use a syringe or eyedropper to put about 1-1.5 ml of Windex on each
pad (my printer has two). Enough so that you see fluid sitting on top
of the pads.
Then turn the printer on, then off so the heads come to rest on the
pads. Let it sit at least overnight, maybe even for 24 hours. After
that, run a couple of head cleaning cycles, alternating with the nozzle
check. If each nozzle check is better, keep going. But if you don't see
any progress after 2 or three head cleanings, repeat the overnight
Sometimes you need to do the Windex soak 2-4 times. And sometimes you
need to do three head cleanings in a row *without* doing a nozzle check
(or anything else) in between. This ensures that you trigger the most
intense cleaning cycle. You can also get a file called PURGEn.TIF on the
MIS site (inksupply.com). n should equal the number of ink cartridges
in your printer. The PURGE files pull ink through the heads without as
much intensity as the head cleanings, and thus wastes less ink.
I tend to alternate all the methods.
This all can take several days. Often, when you see that things are
getting no better, or are getting worse, the print heads just needs to
sit and soak for another day or more. That's what is happening to me
now after Windex soak #2, so I'm going to set it up for another soak and
try again tomorrow.
Eventually, it usually works. At least that's what I've experienced up
to now. Hope this helps.
