Welcome to HP Support Forums. A really great platform for posting all your questions and finding solutions.
 

I understand that you are getting an error that the scanner is in use application '(null)'. (-9925)

I'll try my best to help.

Are you able to make Photocopies?

Please perform a Printer Reset

(1) Turn the printer on, if it is not already on.
(2) Wait until the printer is idle and silent before you continue.
(3) With the printer turned on, disconnect the power cord from the rear of the printer.
(4) Unplug the power cord from the wall outlet.
(5) Wait at least 60 seconds.
(6) Plug the power cord back into the wall outlet.
 NOTE: HP recommends connecting the printer power cord directly to the wall outlet.
(7) Reconnect the power cord to the rear of the printer.
(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
Wait until the warm-up period finishes and your printer is idle and silent before you proceed
 

If the issue persists, please Re-Add the printer to the Mac printer Queue 

1. Click the Apple menu, then click System Preferences.

2. Depending on your operating system version, click Print & Fax, Print & Scan, or Printers & Scanners.

   

3. Check if the name of your printer displays in the Printers list. Do one of the following steps, depending on if the printer is listed or not.

   • If your printer is listed, remove and re-add the printer to confirm communication and to make sure the correct driver is used. Click the name of your printer, then click the minus sign  to delete the printer. Once the printer is removed, click the plus sign , click Add Printer or Scanner, click the name of your printer, then continue to the next step.

   • If your printer is not listed, click the plus sign, click Add Printer or Scanner, click the name of your printer, then continue to the next step.

4. Click the Use or Print Using menu, then select the name of your printer.

      NOTE: Selecting a Generic driver option from the Use menu can result in limited printer functionality.

   

5. Click Add to add the printer to the list.

   • If you are prompted to install software, click Download and Install to complete the installation.

   • Close the System Preferences window.

   • Try to scan

Keep me posted
