BlueDrive Technology is a patented design developed by Ninestar for Canon’s dongle gear cartridges.


Instead of using a mechanism similar to a universal joint like the one Canon employs, Ninestar’s BlueDrive technology uses a shaft that engages directly with a device’s drive motor to rotate cartridge components like an OPC drum or developer roller. Canon’s so-called dongle gear pivots on a hinge so the coupling member

 

is free to move when a cartridge is inserted into or removed from a device. When engaged, the hinged coupler operates at an incline as it transfers the rotational force from the motor to the cartridge components.


BlueDrive Technology is at the very heart of Canon Dongle Gear Cartridges solutions. With smooth installation and removal of cartridge, we guarantee your customers a good printing experience.

 

Employs button to couple the cartridge with the drive motor.


The bottom (blue) in Figure 1 is pressed pressed by the printer's right guide rail and the coupling member (silver) retracts when the cartridge is inserted into the printer.

 

The coupling member will extend to engage with the driveshaft after the cartridge is in position in the printer.


The coupling member can be retractable along the axis of photosensitive drum to engage or disengage with the driveshaft without any inclination.

 

 

 

2014, While several firms have indicated that they were currently working on a coupling solution that does not encroach on Canon’s intellectual property, Ninestar appears to be first-to-market with an actual workaround for dongle gear.


The U.S. CBP has decided that Ninestar's dongle-gear solution is not subject to exclusion from entry for consumption into the United States.


So far, Ninestar has got more than 30 patents relating to the non-rotating gear solution.

 
 

2008, Ninestar began working on an alternative coupling mechanism after Canon released the first cartridges with dongle gear patent.


It took approximately 5 months to develop workaround, which as finalized in 2009.
