GoPrinter™ handheld printers come in two sizes: **12.7mm (1/2 inch)** and **25.4mm (1 inch)**. No matter which one you’re using, loading the cartridge properly is essential to get a clean, reliable print.

## Loading the Cartridge:

**To insert the ink cartridge:**

- Hold it at a 45° angle.

- Align the top edge so that the pins match perfectly.

- Slide it in gently and push down the bottom section.

- Lock the lever to secure it.

If the lever doesn’t snap shut, **don’t force it** as that usually means the cartridge isn’t seated correctly. Eject and reinsert until it locks smoothly. This prevents damage to the cartridge bay and ensures the electrical pins are properly connected.

## Lock Lever Fix (Spring Repair):

**If your locking lever becomes loose or detached, the video demonstrates how to reattach it:**

- Remove the lever and inspect the small spring and pivot poles.

- Reinsert the spring carefully.

- Align the lever’s poles into their slots and snap it back into place.

This fix helps restore firm locking action so your cartridge stays secure during operation.

**Note:** Each printer size uses its own specific cartridge, and **cartridges are not interchangeable** between 12.7mm and 25.4mm models. Forcing the wrong cartridge may cause alignment or locking issues.
