Driver problems with Deskjet 3755

[BrooklynCarol]

I used to be able to scan documents but it isn't working now -- says there is no scanner on this printer. So I followed the help directions on using HP Smart to check the settings and drivers but it says the printer isn't connected. Ever since I bought it I have never been able to connect it using wireless (it always fails)  so I use a UBS cable. I am able to print.

I've reinstalled the HP Smart. Uninstalled the original drivers. Downloaded and ran HP Doctor. Tried the Virtual Assistant. Attempted to install the firmware upgrade but it says there is no printer connected. 

Any suggestions on how to fix this once and for all?

Welcome to the HP support community.

I understand that you are getting a scanner connection error, I am glad to assist you.

Run the Print and Scan Doctor

• Download and run HP Print and Scan Doctor to automatically diagnose and resolve printer hardware and connection issues.
• After the Print and Scan Doctor opens, click Fix Scanning to test your scanner, and then follow any instructions to resolve the issue.

Check Windows Image Acquisition settings

• Windows Image Acquisition (WIA) is a Windows service that helps communication between the computer and scanners. If WIA is not activated, scan jobs can fail.
• In Windows, search for and open View local services.
• In the Services window, scroll down the list and find Windows Image Acquisition (WIA).
• Look at the Status and Startup Type values.
• If the status is Started or Running and the Startup Type is Automatic, WIA is running correctly. Skip to the next step.
• 
• If the status is Disabled or no status displays, right-click Windows Image Acquisition (WIA), click Properties, click the General tab, select Automatic from the Startup type dropdown menu, and then click Start.
• If the Start button is grayed out, go back to the Services menu, make sure Remote Procedure Call, Shell Hardware Detection, RPC Endpoint Mapper, and DCOM Server Process Launcher are running and set as Automatic, and then start WIA.
• Try to scan
