Coleco Adam printer cartridge help

[Tomaso]

I've been having issues with the printer cartridge ribbon not turning as I try to print.  I replaced the O-Ring band on the cartridge with no luck fixing the problem. Upon digging further I found the issue...There is a "+" looking plastic post that goes through the turning wheel and is meant to attach to the bottom of the Cartridge to enable the computer to turn the ribbon (please see the pics below) However the "post" is recessed in the turning wheel and not sticking out the 1/4 inch required to turn the ribbon. My question is I'm probably not the first person this has happened to. What can I do to raise the post that 1/4 inch or so. I pushed the turning wheel down as far as it will go. The post is sitting on an angle in the hole and I can't seem to get it to come out a little further. Is there a way to adjust the height of the post?
