Can't scan

[Janethickman]

My HP 4635 won't let me scan.  I get messages that the status is unknown and that scanning isn't available at this time.  I have now run the Print and Scan Dr TWICE!.  It apparently fixes the problem and allows me to do a "test" scan, which works... yay!  However, when I close out of Print and Scan Dr. and try to go back and scan a doc starting from HP Smart.... I get the same error messages. The first time after running P&S Dr, and it apparently didn't save, I tried turning my computer off and on again.  That didn't work so ran P&S Dr. again.... now what?

Thanks for joining HP Community!

Let's try to Enable scanning to a computer (Windows)

1. Open the HP Printer Assistant. Windows 10: From the Start menu, click All Apps, click HP, and then select the printer name. ...
2. Go to the Scan section.
3. Select Manage Scan to Computer.
4. Click Enable.

Now try to scan.

If the issue persists, I recommend you delete the driver at the root level and Install the drivers, follow the steps below:

Remove the USB if connected

1.) In Windows, search for and open Programs and features 

2.) Select your HP Printer 

3.) Select Uninstall 

4.) In Windows, search for and open Devices and printers 

5.) In the Devices and Printers windows look for your HP printer. If you see it listed right-click on it and choose `Delete' or `Remove Device' 

6.) Open up the run command with the "Windows key + R" key combo. 

7.) Type printui.exe /s and click Ok. (Note: there is a space in between "printui.exe" and "/s") 

8.) Click on the "Drivers" tab 

9.) Look for HP Printer driver. If you see it Click on it and click Remove at the bottom 

10.) Select Ok

11.) Select Apply and Ok on the Print Server Properties windows

12.) Close Devices and Printers 

Then, Click on this link: https://support.hp.com/us-en/drivers/selfservice/swdetails/hp-officejet-4630-e-all-in-one-printer-se... to install the Full Feature Software and Drivers.
