@bobryan1968 Welcome to HP Community!

I understand that you are getting a yellow background while scanning.

Do not worry. I will try to fix the issue.

It's a pleasure assisting you in finding answers to your technical queries.

To provide you with an accurate solution, I'll need a few more details:

Are you facing the same issue while printing from the computer?

Have you tried scanning from a different application?

Are you facing this issue after an update?

Try to make a blank copy and check if you are facing the same issue?

Have you tried any troubleshooting steps on your own?

I suggest you do a Hard 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.

Update the firmware for the printer using this link:https://ftp.hp.com/pub/softlib/software13/printers/oj7720/1909b/OJ7720_1909B.exe
