Hi Welcome to JustAnswer.
It seems,after installing windows 10 computer's settings needs to be done again to automatically select tray based on paper size
Please see its detailed instruction with screenshots in below document. Please follow it one by one and let me know if you face any problem in it.
No you should be able to see this in your printer.
If you are not sure of your printer setting do not change it, Look for part 2 first ,as I believe your setting must have been changed after installing new OS.
From the basic tab you just need to select Auto slect option and Same as front page option as shown in image. Once you do it click apply.
Even after doing this if printer is not automatically pulling trays then you would need to set your printer settings.
Did you check your printer settings ? Do you see tray #2 in drop down option in basic tab ?
Okay . Please try windows setting in this document first. you must be using PDF documents to print.
Please focus on this instruction mentioned in document:-
That's wonderful. Please provide me your valuable rating.
Hoping for the best.
Thank you !!
