TI 810 Blowing F2 fuse

I have a TI 810 dot matrix printer that blows the F2 (3A, 125 V) fuse as soon as the power is turned on. I've disconnected all cables from the motherboard, and tried different power supply, driver, and processor boards, but F2 still blows. Anyone have any ideas?

Print head lowest pin not working

The printhead is probably bad. You can check the cable for complete insertion, unusual wear or physical cuts. There are 2 nuts on either side that attach the head to the carrage. Remove these and you can remove the printhead. There are little coils and hammers that strike the wires. Look at those for burns, misalignment or the wires being broken or too short.
Replace the printhead if necessary.

The paper out switch is on the left behind the paper. It is loose or has gotten bent. Tighten the screws or bend the lever out towards you a little and reinsert the paper.
