C4795 Printer Setup on Windows 10 Fails at last Step

[A_Raybo]

I have a C4795 printer/scanner on our home wireless network. Two days ago, after working for years, the HP Solution Center on my Windows 10 desktop reported it could not find the device.

After several lesser measures failed, I have tried complete uninstall and re-installation of the drivers and software. This fails at the last step, after it says to disconnect the USB cable and after it has printed a clean network test result. As a result, the Solution Center is not reinstalled.

I am able to print from all the programs I have tried (including Paint), but without the Solution Center, I cannot scan - if I try from Paint, it says 'Unable to retrieve picture from device', and 'scan to PC' does not work from the printer's control panel (the error message it shows has no useful information.) On my Mac, however, I can print, scan, get the ink levels and other status. I can also reach the printer's http interface from all devices, including the PCs.

If I initially set up the printer as attached to the PC through a USB cable, the process installs the Solution Center, but if I then try to convert it to a wireless network setup, the Solution Center reverts to not finding the printer.

After the first full-reinstall failure, I used 'Reset Network Defaults' on the printer. This did not resolve the problem.

The Print and Scan Doctor tells me I have out-of-date files, but the substitute it downloads is byte-for-byte identical to the one I was using (PS_AIO_06_C4700_140_408-5.exe from the HP Downloads site), and of course it fails in exactly the same way.

At some point I got a message saying that port 427 on the PC might be blocked from receiving UDP packets, but turning off the firewalls made no difference. I also confirmed (with nc) that the PC could both send and receive UDP packets via that port to/from the Mac (even with the firewalls on), so it is not a PC firewall issue.

When I attempt to install the full software suite, Windows rejects the Bing Bar for HP. I do not know if this is a new policy from Microsoft, or whether this could explain the problems on Windows.

All of the above are experienced when I try to do it from a different Windows 10 machine. On the desktop, I have run chkdsk, sfc and dism, and they do not find any problems.

While I would like to find a way to get the Solution Center installed and working, any solution that gave me fully-functional scanning (including to PDFs) would be better than what I have now.

Thanks for your help - this has solved the problem. There were a few differences from your script (maybe because of the specific Windows version? This is Windows 10 Pro 64-bit version 1809, build 17763.615) that I will mention here, for anyone else having the problem:

Perform root level uninstalltion to remove all the printer related software's.

• In Windows, search for and open Programs and Features.
• Select your HP printer.

Searching for 'Programs and Features' got me 'Add and Remove Programs' (which it called the closest match) and 'Apps and Features', and selecting either of those gave me an 'Apps and Features' panel which lists programs rather than devices. I used this to remove all the HP software I could find in the list.

• Select Uninstall.
• In Windows, search for and open Devices and Printers.

This search did not find anything, but I got to 'Devices and Printers'  via 'Control Panel'. It showed one entry for 'HP C4700 Series' and another for 'HP C4700 Series Driver'. I removed both.

• In the Devices and Printers window look for your HP Printer. If you see it listed, right-click on it and choose "Delete" or "Remove Device.”

• Open up the run command with the "Windows Key + R" key combo.

This is where I started doing something I had not tried before.

• Type printui.exe /s and click OK.
• Click on Drivers tab.
• Look for HP Printer driver. If you see it click on it and click Remove at the bottom.
• Select OK.
• Remove all instances of the same.
• Select Apply and OK on the Print Server Properties windows.
• Close Devices and Printers. 
• Restart the PC again.

For good measure, I reran sfc, dism and chkdsk again before reinstalling. No problems were found.

When reinstalling, as I had found previously that the Bing bar software would be rejected, I deselected that from the list of software to be installed, before proceeding. After that, everything ran smoothly, and everything works again - thanks!
