scan to computer turned off

[sid_f]

I have 2 OfficeJet 8720's and one 7155. they are USB connected to 3 different computers and wirelessly connected to 5 (another 2) in my home. Message says Problems connecting to Scanner. I uninstall the software and reinstall it using the latest version. The printers scan and print after the install but after a day or 2 i try to fix with Scan and Print doctor. It fails with a wain support or something and i always have to uninstall and reinstall the software.  That is kind of tedious each time i want to scan to take 10 minutes to fuss with this. Is Microsoft trying to punish HP?  Any fixes that last more than 2 days before Microsoft attacks the drivers and disconnects the printers.

This might - or might not - be the answer - it is easy to try and you can always "back out" (change it back) later.

The change is for the Wireless connected setups.

** Port Issues - Create a TCP/IP port **

The assigned port may fail to connect the printer or certain printer activities (Scan).  Create / Switch to a TCP/IP Port to facilitate communication and prevent ‘offline’ issues

How-to “Create TCP Port” Contributed by  greenturtle:

Create TCP IP port

1. Print a Configuration Page to get the printer's IPv4 address (you can also tap on the wireless icon on the Front panel of your Printer to get the IP address)
2. On your PC, go to Control Panel, from Devices and Printers, Right-Click the printer and Left-Click Printer Properties, select the Ports tab.
3. Click Add Port, select Standard TCP/IP Port, then select New Port and follow the wizard.
4. Type in the proper IP address for the printer.

This video resource will show you how to do it:
Create & Use TCP IP port

Note that you can ALWAYS revert back to the original port that the HP software installed by selecting the HP port under the Ports tab (in Printer Properties)
