Paul,

I've seen several different cleaning solutions mentioned on this group: 
diluted ammonia, Windex, and other stuff.  What do you recommend for 
unclogging jets or getting rid of gunk stuck to the bottom of the jet 
plates?  I have a C84 with a dirty jet plate and one jet that is 
squirting sideways.  Also, what procedure do you recommend cleaning the 
1280 - printing several pages and soaking the parking station?  Relying 
on the normal head cleaning command?  I've seen some say place a thick 
rag or something under the head and drag it back and forth, but I'm 
afraid that would just force gunk into any jets that are not already 
clogged.  The head cleaning command has not cleared my jet plate now 
for a month.

Thanks for your advice!

Bob,

I use Windex (the version with ammonia) on the outside of the head, and I
use MIS cleaning fluid for the inside -- that is, in carts.  I've heard that
Windex's ammonia is a bit too strong to leave it in contact with the head
for long.

I use 1/2 inch cloth bias tape now instead of a strip of folded paper towel
to get to the underside of the head.  A deflected jet is usually cured with
this Windex-soaked bias tape under the head, pulled back and forth.  Turn
the printer off and move the head over the tape.

Same as the C86 -- cleaning cycles if they work, Windex on the parking pad,
bias tape under the head if there is a deflected jet.

As a last resort, fill a cart with cleaning fluid or buy a cleaning cart.
Some use OEM dye for this also.  Basically, both are non-pigment solvents of
lower viscosity that can get through many clogs and break them up.

Good luck.
