Canon i9900 error light

Hello photo buffs,

This is a shot in the dark, my last hope of hopes, that someone can resolve my printer error before I toss it in the trash.

I have a Canon i9900 printer using on a Windows 10 Laptop,(I am the original owner) that has given me years of trouble free printing, however, not long ago I had a slight paper jam and now I get a green light followed by 5 flashing orange lights with "user error" msg.

Is there anyway to fix this or, as I said, trash it???

Thanks to anyonw with advice.
