1. Use a Phillips screwdriver to loosen the side cover screws (note that both the left and right side covers must be removed; each has one locking screw).
2. Press the clip inside the ribbon compartment and remove the left and right side covers.
3. Use needle-nose pliers to create a small gap between the retaining ring and the shaft so that a flat-head screwdriver can be inserted to pry out the retaining ring.
4. Use needle-nose pliers to pull out the broken locking buckle
5. Transfer the spring from the old locking buckle to the new one
6. Use a support block (a wooden or iron block will do) underneath to prop up the shaft on which the locking buckle is mounted; be careful not to press against the plastic parts.
7. First install the new locking buckle by hand; make sure the square hole aligns with the shaft and the spring hook catches on the mechanism.
8. Press down with a screwdriver (make sure the support block underneath is propping up the shaft) to expose the retaining ring mounting position.
9. Install the retaining ring to complete the locking buckle replacement.
10. Refit the left and right side covers and tighten the side cover fixing screws.
