Pro 6978 won't print or copy

[Mike449]

New (2 months) computer and printer (wireless).  Has been working fine until this morning.  Started out by not printing PDF but woul print other things.  Then about half hour ago it stopped printing - it makes all the noises of printing but sends out a blank sheet.  Now it will not copy either.

HI @Mike449,

Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community! I came across your post and wanted to assist you. I see from the post that you are having issues printing and copying from the printer. Don't worry as I have a few suggestions which should help you resolve this issue.

To provide you with an accurate solution, I'll need a few more details:

Have you recently made any changes on the printer before the issue started?

Does that Scanner bulb light up?

Does the scanner bar move when you open the lid & press the copy button?

Have you tried to perform a Hard reset on the printer?

In the meantime, let's try these steps here:

Perform a Hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector.

Remove all the ink cartridges and then try to perform a hard reset on the printer.

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 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.

Now insert the ink cartridges and then try to print a test page and check if it works.

I would start by checking the installed printer software by downloading and running the HP Print and Scan Doctor. This tool can diagnose and fix many printing and printer software related issues. Please use this link to help you with that information: http://hp.care/2biN2XE 

If you have followed the steps suggested and still having the issue, I would suggest this could be a possible hardware failure. I would recommend you contact our HP phone support for available service related options.
