1.IMPROVEMENTS TO THE LOCK LEVER SPRING.

2.PREVENTING NOI SE FR OM THE TRANSPORT ROLLER PULLEY.

1. Improvements to the lock lever spring.

1.Model Name: SF-2116/ 1016/21 18/1018/2020/1020/2120/1 120

2.General: In order to make it easier to insert and remove the lock lever spring, we have changed

the size of the lock lever axle.

We have increased the A measurement, as indicated in the figure below, so that the lock lever SP rack hooks onto the upper frame more easily (to maintain proper clearance).

2.General: Deformation of a spring in a clutch within the transport roller pulley sometimes caused a

strange sound to be produced. We have changed the shape of the spring to prevent this problem.

3.Description: We have changed the color of the pulley’s resin to make it easy to distinguish the new

and old versions.
