Paper sensor misreads paper size

Hi @MalcolmR,

I'd like to help!

I understand when your print on both sides sometimes the printer reverts itself to single-side printing

Follow the below version of the HP Print and Scan Doctor Utility by selecting your printer:

http://ftp.hp.com/pub/printers/hppsdr/patches/HPPSdr.exe

Be sure to restart your PC and allow the utility to complete the process, then check for any difference. If the issue persists, proceed to the next step.

Install the printer using the TCP/IP port:

1. On the PC, go to Control panel > Devices and printers > Add a printer(at the top) 
2. Under 'Choose a device or printer', click on 'The printer I want isn't listed'.
3. Select 'Add a printer using a TCP/IP address'
4. Find the IP address of the printer by tapping on the wireless/ethernet icon on the printer screen
5. Type in the 'IP address in Hostname or IP address' box, click next
6. Proceed to the next steps by following the on-screen instructions.
7. Try printing

If the issue persists, Install the printer using Windows built-in driver

Refer to this document to know-how. Try printing.

Hope this helps! Keep me posted.
