Make sue there is not scrap of paper under the cartridges:
Check if jammed paper is under FINE cartridge holder.
If the jammed paper is under the FINE cartridge holder, move the FINE cartridge holder to the far right or left, whichever makes it easier to remove the paper.
When moving the FINE cartridge holder, hold the FINE cartridge holder and slide it slowly to the far right or left.
Also if you have not done so reset the printer, turn the power off, unplug it and replug it and turn the power back on.
