Arrow T50P gun jammed - how do you unjam it?

SOURCE: I cannot figure out how to load an Arrow T50P

Turn it upside down. On the end opposite where the staple comes out look for a tab on each side you squeeze to release the staple holder, the staples go in to this holder upside down as well, just push it back in until the releases catch and hold it in. Hope this helps.

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.
