Hi Michael. Welcome to justanswer.
This depends if the ink pads are actually full or not. If it is a false error then I can remove the error by a software but if the ink pads are actually full then it is time to replace the printer.
How old is your printer?
I can guide you through if you want. Give it a shot maybe the error will resolve. The software is free and you can use the trial to check if it works or not.
