Hi @lp100,

Welcome to the HP Support Community

I understand you are facing an issue with your HP Officejet Pro 8600. Not to worry I will help you to get a resolution to resolve the issue.

Let's perform a power drain: 

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till warm-up period finishes and the printer is idle

I think you are using the old version driver of 8600. Which we were using 2 months ago at our office printer which we use very less for best sim offers printing. Which was showing this type of issue. But when I updated the driver of the printer so haven't seen this type of issue again. So try to update the software of your printer.
