SOURCE: jammed makita an923 nail gun
On most all nailguns when the trigger is activated air pressure is released from the headvalve causing the headvalve to open and fire the piston. If air leaks through the headvalve orings or through the headgasket port to headvalve, it will not fire. Try applying light grease to headvalve orings and make sure that headgasket is sealing around vent hole. If it fires then replace orings in headvalve for long term repair. Secondary problem is worn safety parts and trigger or trigger pin. If these parts are worn the trigger will not push the trigger valve pin all the way in when you bump fire the gun. With air supply disconnected, apply pressure to safety while depressing the trigger and check thet the pin is moving all the way into the trigger valve. Adjust or replace as necessary. Enjoy

Not sure exactly what Bostitch framer model you have, but if it is powered by compressed air, as long as you remove the air hose from the nail gun, there should be no risk of the nail gun firing while you remove the jammed nail. There should be a way to access the driver area from the top of the nail gun, even via a latch or a couple screws. Remove the top part of the driver area and that should give you access to the jammed nail, which you can remove. Use long nose pliers or something similar if the nails are really stuck.

You'll have to disassemble it. There is probably a staple lodged in the "hammer" mechanism on the business end of the stapler.
Often, these staple are very difficult to remove -- a very small flat-tip screwdriver and needle-nose pliers usually work best.
After you get all the jammed staples out, lubricate all moving parts with something akin to 3-IN-1 machine oil. This should prevent future jams.
