I can print, but not scan anymore?

[Ann-Mari_O]

I can still print documents theough a wireless connection to my laptop (Lenovo), but when I try to scan a document my printer tells me there is no computer connected... Scanning still worked the other day - how come it's been disabled, and how do I fix this? Thank you!

Hello,

Please restart the printer, computer, and router for solve this problem.

1. Turn the printer off, and then wait 10 seconds.
2. Disconnect the printer power cord from the printer.
3. Turn off the computer or the device you are trying to print from.
4. Connect the printer power cord to the printer, and then turn on the printer.
5. Disconnect the power cord from your wireless router, and then wait 30 seconds.
6. Reconnect the power cord to the router.

    NOTE: 
   

   Wait until internet service is restored. Internet service is interrupted while the router is off.

7. Wait at least 3 minutes, then turn on the computer.
8. Try to scan and print.

If the issue continues, please check the Windows Image Acquisition (WIA) service to see if it is working properly by doing the following:

1. On the keyboard, press the Windows flag and the R key simultaneously. The Run window opens.
2. Type services.msc and OK. The Services (local) window opens.
3. Double-click on Windows Image Acquisition, then click on the Connection tab.
4. Check Local System Account and Allow the service to interact with the office.
5. Click on the Dependencies tab and check that Remote Procedure Call (RPC) and Kernel Hardware Detection exist in the first window.
6. Click on the General tab, and restart the service by clicking on Stop, then Start.
7. Close the Services window.
8. Try to scan.

If the Kernel hardware detection dependency does not exist, please add it as follows:

1. Simultaneously press the Windows flag and the R key. The Run window opens.
2. Type regedit, then OK. The registry editor opens.
3. Expand HKEY_LOCAL_MACHINE, then SYSTEM, CurrentControlSet, Services and select StiSvc.
4. In the right pane double click on Depend on service.
5. You will find RpcSs, just add ShellHWDetection below then click on Enter and OK.
6. Close the registry editor.
7. Try to scan.

I remain at your disposal in case of need.
