Forcing pressurized fluids through the print head on Epson printers is
not wise, as they may delaminate, so I don't suggest it, in general, and
particularly with a head that is quite clogged.

The reason the alcohol by itself isn't working is because it is not an
effective solvent with Durabrite inks such as those used in the CX and C
printers.

The solvent required to dissolve the resin in the pigment inks (which is
an acrylic) is ammonia. This is why I suggest using ammoniated window
cleaner, which has some similarity to the inks, in that it has glycol,
alcohol, and a relatively high pH but the dilution of the ammonia in it
is such that it won't damage metal components, and such.

Your post is definitely a keeper. Tremendously useful.

Thanks Art!
