Since those steps did not resolve the issue, the next step is editing the registry. However, the step afterward would be reinstalling Windows.
Please ensure you are comfortable performing the below steps, since you will be editing registry settings.
Go to the Start menu, type "regedit" in the search bar, and hit enter. You may have to provide administrative permission to open the program.
Before you do anything else, you will need to back up the registry. To do that, go to File, and click on Export. Name it anything you want, then hit Save. This will save a current copy of the registry, just in case you delete something accidentally.
Go to the Edit tab, then click on Find. In the search box, type "7280" (since that is the primary number indicator of the printer you own) and click Find Next.
It will scan the registry from the beginning to end, locating one entry at a time. Some keys, entries and files will have 7280 in the name. Only certain ones will be relating to the printer, and they will have some indication in the description (it will contain information regarding a printer or scanner, and some will even have "OJ" in the name for Officejet). When it finds one of the entries, and you have confirmed it is related to the printer, within a reasonable doubt, you can delete it by hitting Delete on the keyboard.
Once one entry is deleted, hit F3 on the keyboard, which stands for Find Next. It will locate the next entry containing "7280". Repeat the process until all 7280 printer entries are deleted.
If you accidentally delete something you shouldn't have, all you have to do is upload the registry backup you saved. To do that, click on File, then Import. Select the backup and import it. You will have to repeat the process and re-delete anything related to the printer again.
After this is done, all "7280" entries of the registry, relating to the printer, should be deleted. Hopefully, this will delete the corrupted files associated with these entries. If some entries will not delete, and provide an error of some sort, just skip that entry and move on to the next.
Afterward, just restart the computer, and perform the next few steps before you install the printer:
Go to the start menu, type “CMD” in the search bar. Now, you should see a shortcut for CMD above. Right click on it, and click “run as administrator”. If it asks you for administrative permission, please allow permission.
You should see Command Prompt open. Type in this command and hit Enter afterward: sfc /scannow
SFC stands for System File Checker, and it scans and attempts to restore corrupted Windows files. Running this might find a corrupted file or service and repair it. After it completes it will basically say either no corrupted files were found, corrupted files were found and repaired, or corrupted files were found but were unable to be repaired. Restart after this completes and continue on with the next step.
As another precaution, I would prefer it if you create a new administrator user account, just in case there is some hidden corruption based off of your current user account. In your Command Prompt window (as administrator), type the following and hit Enter: net user administrator /active:yes
You should see a message saying "the command completed successfully". After troubleshooting is done, you can disable this account by typing the following command into Command Prompt (as administrator): net user administrator /active:no
Restart the computer, and utilize the new account that is available, which should be named "Administrator". In this user account, try to perform the tasks you have been attempting.
This is the most thorough troubleshooting I can provide, based on the context and situation you have established. If these steps do not resolve the issue, you will likely be required to reinstall Windows. Please let me know when you complete this troubleshooting.
