Common problems HP Solution Center not working : Adobe Flash Player Error and Unable to scan
We would like to share some of the most frequently asked questions about HP Solution Center not working : Adobe Flash Player Error and Unable to Scan.

HP Officejet Pro 7740
Microsoft Windows 10 (64-bit)

I received messages that my Printer is not supported and now i get constant errors. Does Out of Warranty mean HP sabotages my device to NOT WORK?

I like the scanner and occasionally print. The Software making me connect to HP is unnecessary. I war referred to HP Scan and Capture and it more often than not fails saying that my Device is Busy?
Is there software that works without HP (Big Brother)? Is there a trick to HP Scan and Capture

Hi @PeterBishop,


Welcome to the HP Support Community


I understand you are getting an error message Printer is not supported when you try to scan with your HP Officejet Pro 7740 printer. Not to worry I will help you to get a resolution to resolve the issue.


To assist better:

  • May I know which software you using to scan from your PC?
  • Could you please share a screenshot of the error?
  • Was there any update on the printer or PC recently?
  • How is the printer connected to your PC?

While you respond to that, Let's perform a power drain: 

  • With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
  • Remove USB cable, if present.
  • Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
  • Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
  • Turn on the printer and wait till warm-up period finishes and the printer is idle


Update the printer firmware & Perform a Windows Update

  • Click here to download and install the latest printer firmware from your product
  • Click here to know different methods of updating printer firmware.
  • Windows Update: Select Start  > Settings  > Update & Security  > Windows Update , and then select Check for updates. If updates are available, install them.

If the issue persists, then please follow the below-mentioned steps:


 Use HP Print and Scan Doctor to check connectivity

Download a special version of HP Print and Scan Doctor specifically created to help with printer offline conditions.

  1. Download HP Print and Scan Doctor.
  2. Run HPPSdr.exe from the download location on your computer.
  3. Once HP Print and Scan Doctor opens, click Start, and then select your printer.
    • If your printer is not in the list, turn it off and on, and then click Retry.
    • If there is a connection problem, follow the instructions in HP Print and Scan Doctor.
  4. If a screen prompts you to turn on printer updates, click Yes.

  6. Select Fix Scan and continue with the on-screen instructions

Reinstall the HP print driver (Windows)

Uninstall then reinstall the print driver on a Windows computer.

--->In Windows, search for and open Programs and Features.

Check Windows Image Acquisition settings

Windows Image Acquisition (WIA) allows communication between the computer and scanner. If WIA is not on or running correctly, scan jobs can fail.

  1. In Windows, search for and open View local services.
  2. Next to Windows Image Acquisition (WIA), check the Status and Startup Type.
    • If the status is 'Started' or 'Running' and the Startup Type is 'Automatic', WIA is working correctly. No further action is required.
    • If the status is 'Disabled' or blank, continue with these steps.

Windows Image Acquisition service status

  1. Right-click Windows Image Acquisition (WIA), and then select Properties.
  2. On the General tab, select Automatic from the Startup type drop-down.
  3. Under Service status, click Start.
  4. If the Start button is grayed out, return to the Services list and make sure the following services are running and set as Automatic.
    • DCOM Server Process Launcher
    • Remote Procedure Call
    • RPC Endpoint Mapper
    • Shell Hardware Detection
  5. Try to start WIA again.

Hope this helps! Keep me posted.
