Alps wax thermal are not impact. Just heat.

Why not mix some refill black inkjet ink? It's meant to go through the
heads. The glycol will dry, it just slows it down and perhaps a bit
of heat will speed that up.

Ritz dye has a lot of salt in it.

Don't use an air compressor! You'll almost certainly ruin the heads.
Even using a syringe to clean the heads, you must press only slowly
and never very hard.
