Hi,

I got an old HP 720C machine that uses the HP 23 color cartridge and
HP 45 black cartridge. I tried to revive the color cartridge by
refilling it. I got all the colors working except Cyan wouldn't come
out, so it must have been clogged. I soaked the printer head in the
cleaning solution, and now Cyan is coming out fine, thus I get blue
now. But now Magenta prints but very lightly and also with lots of
banning. I already tried cleaning the contacts on both the inkhead
and the printer as well as unclogging it to no avail. Any suggestions
on what's wrong?

Any help greatly appreciated.

Thanks

Lester

soak it a little longer or find someone with a ultrasonic jewelry cleaner.
