How to Load an Electric Stapler | Two Types, One Straightforward Process

The mistake most people make on their first try is forcing staples in the wrong way, which jams the tool before it ever fires. One quick look at the magazine — does it slide open from the front or the bottom? — tells you everything. Below are the exact steps for both types, pulled straight from the manufacturer instructions, so you can load it right on the first attempt.

Office Electric Staplers: Front-Load Magazine

The most common desktop electric staplers, like the Bostitch Impulse series, load from the front. You don’t need to unplug these during loading — most have an auto-lock that disables the motor when the magazine opens — but unplugging is never wrong.

1. Push the release button on the back of the stapler. The front tray pops open or slides forward.
2. Drop a strip of standard 1/4-inch office staples into the channel. On nearly every office model the staple legs face down (toward the base of the stapler).
3. Slide the tray closed until it clicks. A small red light on some models turns on when staple levels are low — that is your refill signal.

After loading, rotate the anvil on the base 180 degrees if you want the stapler to temporarily mark instead of permanently bind — a useful trick for collating without commitment.

Utility Electric Staplers: Bottom-Load Magazine

Construction-grade electric staplers, like the Stanley models built for upholstery and trim work, load from the bottom. These run on standard 120V AC power. Safety is non-negotiable here: unplug the tool and set the switch to “off” before you open anything.

1. Hold the stapler upside down so the bottom faces you.
2. Squeeze the latch on the bottom and pull to open the magazine channel.
3. Insert a strip of T50 staples (up to 1/2 inch) with the legs facing up — toward the ceiling, not the floor. This is the opposite of the office stapler orientation.
4. Push the latch closed until it locks. Plug the tool back in, and it is ready.

Brads load into a separate side channel on the front, with the legs tilted against the channel wall — the manual shows the exact angle for your specific stock number.

Three Loading Mistakes That Jam Electric Staplers

Jams happen, but almost always from one of these three errors. Knowing them in advance saves the ten-minute fix:

• Staples upside down. On a bottom-load utility stapler, legs face up. On a front-load office stapler, legs face down. Mix them up and the staple bends inside the channel before it fires.
• Wrong staple size. Office models take standard 1/4-inch staples; utility models take T50 staples or specific stock-numbered brads. A staple that is too long or too short skips the driver track entirely.
• Stapling while plugged in. Utility staplers can fire accidentally during loading if the power is live. Unplug first, every time.
