I have an HP Officejet Pro 8610. The printer has worked well until I recently installed off-brand ink cartridges for the first time. I now get the “Missing or Failed Printhead” message and I can’t print. I’ve tried every troubleshoot online and in the message boards. Can this issue be fixed by simply replacing the off-brand ink, or might there be permanent damage to the printer? There doesn’t appear to be any blockage of ink or backup of debris.
