All lights are flashing and I cannot turn the printer off.

I have an HP Officejet 8040. All lights are flashing and the printer will not turn off. I unplugged power cord from printer, and then from wall several time from 30 seconds to 2 hours.

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, I appreciate your efforts to try and resolve the issue, to provide an accurate resolution, I need a few more details:

• Did this happen after a recent window or software update?
• When was the last time it worked fine?

While you respond to that, let's try these steps: (Do not skip any troubleshooting steps even if you feel steps are repeating)

• 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 the warm-up period finishes and the printer is idle.

Hope this helps! Keep me posted for further assistance.
