Printer Paper Sensor ERROR

[RAS7]

My mother keeps sending a standard 81/2x11 page to print and the  printer keeps saying printer sensor dedects wrong size paper in tray, or requested size of printing is incompatable with paper in tray.

I, her son has verified that the properties on the computer is set for normal stationary letter size and the paper in the tray is  normal letter size.

We have rebooted, turned everthing off, gone to HP auto fix software as instructed and all says everything is working  well...

Does anyone have a suggestion or should we just reinstall the printer softward with the provided disc when printer was purchased??

If you are satisfied that you have set / adjusted the settings in Printing Preferences that should have corrected the issue, then yes - you can certainly remove the existing printer programs (Control Panel > icon view > Programs and Features) > Reboot > install a fresh copy of the Full Feature Software for your Operating System.

If you wish, do first see what the Doctor says about the problem:

• Start Here: HP Print and Scan Doctor – Help Resolve Printer Issues

Windows - General Instructions to remove / install Full Feature Software

Printer:

HP ENVY 4520 All-in-One Printer

• If using a USB cable to connect the printer and computer, disconnect the cable
• Create a Restore Point
• Reinstall / Update your PDF Reader (Adobe Reader DC / Foxit Reader)
• This works best if the computer's Windows (10) Updates are current - check if you are unsure
• Update your HP Drivers (or other vendor computer) - printer software likes updated Drivers
• Verify / Switch-on Network Discovery and Print Sharing
• Open Printer Website Driver Support Page >
• Download a fresh copy of the Full Feature software >
• Remove existing Printer Software by preferred method:
  1. Control Panel > icon view > Programs and Features > Right-Click on program > Uninstall
  2. Settings > System > Apps and Features > Left-Click on Application > Select Uninstall >
• Shut down the computer > boot, and log in >
• Install Full Feature Software (find in your Downloads folder > Double-Click on the file) >
• Restart the computer and log in to finish the installation
