My printer has suddenly gone to scan only

[05illoyd]

Hi, I've got a HP deskjet 3750 a year ago, it has been working absolutely fine. I turned it on today and it wouldn't print, it was connected but was just saying error in the printer queue. I used the HP print and scan doctor and it seems even more broken, it renamed the printer as "HP736A98 - scan only DO NOT DELETE" and when I went to print something it let me select it but will only print blank pages. 
I've tried the obvious turn it off and on again for both printer and laptop. I've also tried removing the printer from the laptop settings 'printer and scanners' list and readding, it's come back with its old name but when I go to print it's still acting like it thinks its only a scanner!
Any ideas? 
Thank you very much to anyone able to help!

Hi @05illoyd,

I'd be happy to assist you  

I understand you are unable to print.

To assist  better-

1) Does the copy print out the same way? 

2) What's the application you are trying to print from? Have you tried printing from a different application or devices? 

While you respond to that, let's print a Print Quality Diagnostic page -

1. Load plain white paper in the tray.

2. Print the report from the HP Smart app or the full feature printer software.

   • Windows: Search Windows for your printer name to open HP Printer Assistant. Click Maintain Your Printer, select the Device Services tab, and then click Print Quality Diagnostics Page to print the report.

Post the Print Quality Diagnostic page here so we can help you further. 

You may also refer to this document with steps to fix " Print Quality Issues" issue applicable for your printer -Print quality  

 Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware 

Let's try and uninstall the printer software from the root level on your PC and install the full feature printer software to resolve the printing issue 

First, unplug the USB cable from the printer if present.

• Go to Control panel – Programs and feature – Select all the HP printer entries and uninstall them.
  • Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.
  • Restart your computer.
  • Click the bottom-left Start button on desktop, type device manager in the search box and tap Device Manager on the menu.
  • Once in device manager, click on the view tab in the top & choose “Show hidden devices”.
  • Then from the device manager list, check the entries under “Printer” – If there are any entries, please right click and choose “uninstall” – In the confirm device un-install pop-up, make sure you select the box which says “Delete the driver software for this device". 
  • Also, check the entries under "printer queue" and "imaging devices" and repeat the same exercise. Delete any printer entry or any entry which says “Unknown device”.
  • Once done, close device-manger. 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 running window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.
  • Once done you can try cleaning out your temporary files and cached files. You can try using automated applications like some cleaner software's that you can download from the internet.
  • Now restart your computer again.
  • Open the Run window again, type “services.msc” and press ok to get services window.
  • Scroll down to “Remote Procedure Call (RPC)” – right-click and go to properties. Make sure the service is started and startup type is “Automatic”.
  • Now scroll up and go to “Function Discovery Provider Host” – right-click and select properties – Change the startup type to “manual” and start the service.
  • Repeat the same exercise on “Function Discovery Resource Publication” as well
  • Windows image acquisition stop and restart the service 

Reinstall the drivers from Software and drivers page

Hope this helps! Keep me posted.
