If your HP Officejet Pro 8600 e-All-in-One Printer is displaying an error message indicating a problem with the printer or ink system, and restarting or disconnecting the printer does not fix the issue, follow these steps to troubleshoot the problem:

Reset the Printer

1. With the printer turned on, disconnect the power cord from the printer.
2. Unplug the power cord from the power source.

Clean the Printhead
