Laserjet Pro printer M479 won't scan

[KernowUK]

My new Laserjet Pro 479dw won't scan.  There is an incon on my desktop for scanning but when I click on it it says the printer wasn't found.  I then run the icon Scan Doctor.  It goes through everything, says all is ok, and even does a successful test scan. So I finish and close that.  But when I do I get this!!!  It's just fixed and tested everything but says it can't find the printer!  How ludicrous is that!   Any and all help gratefully received.  😢

Hi KernowUK,

Welcome to the HP Support Community

I understand you are facing an issue with your Laserjet Pro printer M479 won't scan. Not to worry I will help you to get a resolution to resolve the issue.

Let's try resetting the printer and check once

1) Take out the cartridges.  

2) Unplug the power cord from the printer & wall.  

3) Wait for 30 seconds.   

4) Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not into a surge protector.  

5) Insert the cartridges back into the printer.

To assist better:

• Does the copy also have the same issue?
• Are you able to get good-quality scans using the automatic document feeder?
• What application are you using to scan?
• Have you tried using an alternate scanning application?

While you respond to that, 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

Many thanks.

First I tried completely uininstalling and reinstalling the software for the printer, and that did the trick.

I'm left with just one anomaly, and that is my HP Support Assistant tells me I have two updates and I must perform a restart.  But when I do this, the Assistant doesn't change - it still tells me to perform a restart no matter how many times I do it!
