It is new cartidge
The old one gets the same response
How do I do this?
I think I should switch the computer of first before switching off the printer. Correct?
The error only shows on the computer.
I am not sure what you are telling me to do
It has made a colour copy fine
I did try a restart this morning. Made no difference
There is no Delete option. Would "Remove Device" be correct?
What do you mean by "Re9nstall printer" before connecting the usb cable?
Thanks very much I will try that later
