Problem for HP PSC 750 All-In-One InkJet Printer
Clogged inkjet ports on an hp psc 750xi
By t_zieglerjr on Jul 27, 2008
I tried printing a document on the printer and got blank pages as a result. I tried using an old toothbrush to unclog the jets, but this only worked for about fifteen pages. I still need to clean the ports so I can print again.

UNCLOG INKJET PRINTHEAD NOZZLES
Soak the printhead in hot water ! It works !!
_submerge printhead in aprox 0.1 inch water in plate
_hot water from faucet.... heat plate and water in microwave
_do not exceed 160 F or too hot to touch
_soak until ink comes out in water...
....usually a minute is good enough...sometimes 15 min
.....if it works and then goes dry soak some more
ALSO
CHECK THAT THE CARTRIDGE HAS INK by postal scale weight or by feel.
Compare to known full and empty carts....ink is about one ounce
and empty cartridge 2-3 ounces.
