Problems with scan

HP Recommended
HP DESKJET 2540
Microsoft Windows 10 (64-bit)

I have a deskjet 2540. When I try to scan a document, the system gives me the folollowing message: "unable to establish communication ". Until a few days ago the scanner was working perfectly. I have already tried uninstalling and reinstalling the drivers.

Thank you for posting on HP Support Community.
 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

  • 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 the warm-up period finishes and the printer is idle.

Hope this helps! Keep me posted for further assistance.

Thank you for posting back.

 

Let's try this: 

Root level uninstall and reinstall printer drivers

  • Go to Control panel – Programs and feature – Select all the HP DeskJet printer entries and uninstall them.
  • Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.
  • Then press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" and press enter.
  • Under print server properties, go to drivers - remove any entry there as well.
  • Again, go to run window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.

To reinstall, click here.

 

Hope this helps! Keep me posted for further assistance.
