Wiress scanning is unstable under MAC OS X El Capitan

Color LaserJet MFP M477fdw
Mac OS X 10.11 El Capitan

Hello, sometimes I can use HP Easy Scan or Printer & Scanner to scan documents but sometimes I can't. I often get a communication with scanner error code -9923. I can use wireless connection to print documents though.

 

In some threads, HP recommended uninstalling and reinstalling the driver as well as turning on and off the printer.  Two days ago, I did that but it did not help. Yesterday, all of a sudden, it worked again.

 

Is there a way to make the wirelss scanning stable permanently?

Hi fish_coke,

 

The first thing that comes to my mind based on your description is that you might have a weak Wi-Fi signal between your router and the printer.  Scan connection failures are more likely to be observed because the device must be immediately available to capture and transfer the image whereas a print job is submitted to a print queue on your Mac where it awaits printer availability until it can be printed.

 

Signal strength can be affected by many things in your environment.  If you haven't already, I suggest you take a look at  at HP's Wireless Printing Center.  Lots of good information provided there.

 

Hope this helps,
