This device was working before. Now, it just stop working the scan feature. When I send pages to print, its work fine. I have uninstalled a couple times the drivers and reinstalled again. nothing happen. The printer is connecting by lan and the hp scan doctor can detect this printer on the network. any clue?

Thanks for taking an interest in the HP Support Forums After reading your post I see that you are getting scanner connection issue. I will be a delight to assist you here.

Superb analysis and brilliant diagnosis of the issue before posting. 🙂  Kudos to you on that score.:)

For better clarity and to assist you better I would require more information regarding this:

• When did this issue start?
• Did you do any changes to the printer?

Meanwhile

Restart devices and check driver scan settings

1. Turn off the printer.

2. Make sure the printer power cord connects directly to an electrical outlet and not through a surge protector or power strip.

3. Close all running programs on your computer, and then shut down the computer.

4. Turn on the printer.

5. Turn on the computer.

6. Search Windows for your printer model name, and then click the printer name in the list of results.

   • If HP Printer Assistant opens, click Scan a Document or Photo or Manage Scan to Computer, and then make sure the check box is selected next to Automatically start Scan to Computer when I log onto Windows.

   • If HP Solution Center opens, click Scan Settings to view scan connection status, settings, and preferences.

7. Try to scan.

Check Windows Image Acquisition settings

1. Search Windows for view local services, and then click the View local services Control panel setting in the list of results.

   The Services window opens.

2. Find Windows Image Acquisition (WIA) in the Name column and look at the Status and Startup type values.

   • If the status is 'Started' and the Startup type is 'Automatic', WIA is running correctly. Skip to the next step.

   • If the status is 'Disabled', right-click Windows Image Acquisition (WIA), click Properties, click the General tab, click Start under the Service status, and then select Automatic from the Startup type dropdown menu.

        NOTE:

     If you cannot start WIA, make sure the following services are also Started and set as the Automatic startup type.

     • Remote Procedure Call (RPC)

     • Shell Hardware Detection

     • RPC Endpoint Mapper

     • DCOM Server Process Launcher

3. Try to scan.

Temporarily disable firewall software on the computer

1. Return to the Print and Scan Doctor, click Network, and then click Troubleshoot Firewalls.

   Figure : Troubleshoot Firewalls in the drop-down menu

   

2. Click the name of any firewall software on your system that has an Enabled status, and then click Disable.

   Figure : Example of the Troubleshooting Firewalls window

   

3. Try to scan.
