HP ENVY Photo 7855
macOS 10.14 Mojave

I have a NEW Printer (7855).  I get this error message like many other people  -9923 stating there is some communication error...    I can Print Documents and photos just fine.

I can actually Scan a document by using my iPhone but from the iMac, the printer will not scan.

 

I downloaded the HP Easy Scan App but it still will not work.  When I first bought this printer two months ago (Sept 2019) I tested the scan and it worked fine.  But now...  no luck.

Hi,

restart both your printer and the Mac and check if you may see any difference.

 

If the same persists, try following HP Easy Start to ensure the HP Essential Software and HP Easy Scan apps are up to date:

I had to go to step two you offered.  It seems to work from the "Easy Scan" App, but still won't scan when using the "HP Smart" App pinned on my iMac App Dock....
Thank you for your time!

I have the same error message.  I have restarted my computer and printer.  I have gone through the entire start-up process.  I can do a test print in the startup but I receive error message when I try to scan.   I have had my scanner for 3 years.  This is something new

I updated software and downloaded the "HP Easy Scan" app from a solution given to me by "Shlomil" and I can scan from the printer to my computer now.

 

Hope it works for you.
