The most common cause of the gun not firing is loading it with the wrong staples. Look at the packaging for the staples and see if it lists the gun. Staples are NOT universal and are make for specific staple guns.

How to Load Staple Gun

How to Troubleshoot Staple Gun Hunker

Staples newly purchased will always be attached when purchased and that answers your question...wherever the device u are loading has a horizontal channel, there will be a loading window at the end. Take it apart by realeasing the cap or spring at the bottom and sliding the train of staples into the channel inside. Replace cap or spring lever to original position and secure. Stapler is now loaded.

On the back there is a small metal piece that is spring loaded push it in and down and that should release it pull it out and slide staples in replace assembly remembering to push in and up to reinstall holder .Hope this helps.

When you lift up the top of the stapler (as though you are going to put staples in), does the pusher slide freely back and forth? It might be getting stuck at some point and not pushing the staples (either due to a worn pusher spring, or friction). First (after removing the staples) try spraying some light oil on the mechanism and lifting the top part of the stapler up and down a few times and observe how easily it moves back and forth. Also, with the top open try GENTLY sliding back and forth a little - if it slides fine with no sticking, try loading staples and using stapler. If it slides ok, but doesn't quickly return to it's "normal position" when pulled so as to put tension on the spring, rhen the spring may be worn and need replacing.

Try loading with fewer staples to see if that helps and make sure there are no loose staples jamming the mechanism.

there should be a button / lever at the rear press it and it should open so as to insert the staples

Does your copier have the finisher or saddle to have staples? There should be instructions in the user manuals for replacing staples. If you don't have the user manuals, I'd ask Canon to purchase replacement copies or look on the web.

Fire the stapler with the load chamber open and down, see if anything falls out. Point it in different positions and fire it, just make sure it cannot fire anything at you.

pull out the spring at the end of the gun. turn the staple gun upside down. Lay the staples in the track pointed side up, push in the spring slide so that it locks. You are ready to staple.
