Solved: Re: Scanner won't connect wirelessly - HP Support Community

loosbroos · ‎12-09-2016

The scan function of my printer has stopped working wirelessly.

It will print wirelessly, and scan if connected to my Mac with a USB cable (plus the Copy function on the printer works so the scan function is working normally) but it will not scan wirelessly.

It was working up until a few weeks ago but now when I press the 'Open Scanner' button the Scanner window opens but it just says it's 'Waiting for scanner...' - forever!

I have tried re-starting both the printer and the Mac, updating the printer driver, uninstalling the printer from my Printer list and re-installing, and even installing the latest Mac OS (Sierra - it was working ok with El Capitan but then just stopped).

It obviously isn't a wireless connection problem otherwise the printer wouldn't work wirelessly, and it's not a scanner problem or it wouldn't work when connected by USB. It seems very wierd to me- I have never encountered this problem before.

...can anyone help?

Hi,

Generally scanning is a lot more complex communication than printing, therefore netowrk issues may only affect scanning.

When you press the plus button under System Preferences > Printers & Scanners, do you see the printer listed as Bonjour as expected?

Try following any remaining steps in here, these may help too:

http://support.hp.com/us-en/product/HP-Deskjet-F4500-All-in-One-Printer-series/3944755/model/3944756...

If the issue remain, scanning from Windows would be a good test, to deny any multicasting issue which will only affect Mac.

Parallels, as a virtual OS provide Shared Networking by its default configuration, meaning your VM establishes its own subnet and gateway, meaning this is virtually a different network than your standard one.

You may find more about its networking capabilities detailed below:

I suggest trying to set a Bridged Ethernet or WiFi mode, meaning the virtual OS is a part of your standard network envoirnment, meaning it will have the same subet and gateway as your Mac, then it should allow communicating with the printer through the local network as it should.

You may try following these steps and check if these may help changing your VM network settings:

Thanks for the prompt reply. I went to the post by ShlomiL as you suggested but the fix didn't work - besides this seems specifically aimed towards the problem occuring after installing Mac OSX Sierra - my problem started while I was still using El Capitan - I only installed Sierra in the hope this would fix it

Also just for info the link for downloading the latest version of Easy Scan in the ShlomiL post didn't work - it opens a webpage with the message 'Not Found' ...so I got the latest Easy Scan app from the Apple App Store

Anyway I downloaded the latest drivers and uninstalled Easy Scan as the ShlomiL post instructed then re-installed the app but it still doesn't work - after opening it just sits there waiting for the scanner to respond, the same as it did with the Apple Scan app (I only installed Easy Scan today in the hope it might fix the problem but it's just the same as the Apple app - it just sits waiting for the scanner to respond)

Any more ideas?

Hi,

Sorry, I thought your post indicated you are using macOS 10.12 Sierra.

Thanks. Maybe I didn't explain it enough in my original post.

I am using Sierra now but was using El Capitan when the problem first occured.

I only installed Sierra in the hope it would fix the problem

Thanks heaps - I really appreciated it

Hi @loosbroos,

Please try performing a full restart scycale to all your device, I can see you have restarted your printer and your Mac, a roueter restart might by crucial in here..

Uplug your router power for a few seconds, replug it and allow it 3 -5 ,omites to initialize till you can access the internet again.

Now reboot both the printer and the Mac and try scannomg from Image Capture again.

If the same persists, may you had any metwork structure change lately?

Such as a new router, firmware upgrade to your router, etc.

May you moved your printer to another location in your home? how far is it approx. located from your router?

What is your router brand and model?

Please let me know how it goes, for any issues let me know the indormation above.

Regards,

Shlomi

Hi Shiomi
Thanks for the info - I will try that tonight when I get home.
I've had problems before with complete wireless connection failure & restarting the router fixed it but I thought that because the printer works ok wirelessly it couldn't be a router problem.
Get back to you tonight
