Hope some one can help.

Color stylewriter pro - yes I know it's old - started displaying a message
along the lines of "waste ink tank is full" but kept printing while my
daughter was using it - hence I did not see the exact message.

That message now no longer appears but the printer refuses to recognise the
black ink cartridge and gives the normal:

"the black ink cartridge is either missing or empty................."
message.

I have replaced the cartridge and still no success.
Prints in all other colours.
Using 8.6 on a G3 266.
Any thoughts or suggestions will be appreciated.

Either of these Apple Tech notes may be appropriate.
