Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
Most of the time, the printhead has to be replaced when you receive that error.
The problem with replacing it is the cost. For instance, you can get a new 8610 printer here for barely more then the cost of the printhead. http://amzn.to/1T5w9nw
And here is the printhead itself http://amzn.to/1PXz0Le
This document will show you how to replace the printhead.
Before you buy a new printhead, I strongly suggest you run through the document above.. Remove your old printhead, clean the electrical contacts on it. Unplug the machine from power.. Wait a minute.
Plug it back in and then insert the same old printhead you have. That may get it working again.
If not, you will need to either purchase and install a new printhead. Or consider a new machine.
If you have further questions, let me know.
