Toner cartridge is jamed

Hi there my toner cartride is jammed and will not rotate to get it back into a position where I can remove it. It is as if it has not seated in place or is slightly too long and now it is wedged against the edge of the hole where you insert the cartridges and will not budge back or forward - stuck! I have pressed in the little catch that usually allows me to rotate them into posiion in and anti clockwise direction but because the cartridge is jammed against the edge it will not rotate at all. Any ideas how to get it out - solve the problem??
