Can anyone tell me why my HP970Cse printer has decided to
quit printing the color blue. No I didn't run out of
ink. I have tried 4 different HP6578A cartridges and they
will print all colors on the initial installation, then
not print any of the blue or green colors the next time I
try printing. I have tried ALL of the cleaning and
purging "tricks" on each cartridge so it has to be
somewhere in the printer. I have also uninstalled and
reinstalled the drivers. Should my next printer be an
EPSON! .
