to use the USB port , you need the CUSTOM PC software (now gone)
what is the chance 15 year old software runs on windows 10?
call them and ask them, their web site forgot it existed.

the maker shows zero support on 15 year old products.
the manual does not cover this software name or usage. (my guess other manuals lost for that)

Turn the printer off
Open the back door and
gently turn the paper roller upward until it clicks. Make sure the door is securely closed. Wait a few more minutes then turn the print back on. I hope this helps.
SOURCE: from left hand side 10 keys not working
You might check settings first. The keyboard might be set to a mode where those keys have some function besides notes. Try a master reset and see if hings start working.
If it was working and now those keys don't, a fault has probably developed. There may be problems with connections to the keyboard, or there's been a component failure.
Sometimes getting into these things and accessing the keyboard is a challenge, and it's possible to do more harm than good. If it needs repair, you're probably better off taking the keyboard to a musician's store in your area and asking them to give you an estimate for the work (or to recommend a servicer if they don't do the work themselves).
