Conventional cartridges in laser printers contain many moving parts, requiring gears driven by a motor. This can cause uneven image printing because of gear vibration.
Canon’s unique Coupling Gear technology, used in many of our laser printers, reduces the number of interface gears required in a cartridge. This achieves smoother transition ensuring even and flicker-free image output. As a result, you benefit from
higher quality print outs with a smooth and stable finish.
