Can a Koad Easy Share G600 printer dock be fixed?

As usual, I was having difficulty with paper feeding.
I took two sheets in, and silly I, pulled them out. It
now locked down..to speak...it won't do anything now.
It says replace cartridge and press print...it is a brand new cartridge. We can't remove the cartridge either.
So, that makes me feel it is locked down in the process of printing the picture. HELP! It is a Kodak Easy Share G600 printer dock.
