Ninestar provides double protective designs: Chip with Battery and Cartridge Structure Optimization on the solution for Brother TN760/TN2420 Series Products. Ninestar’s solution is to use a chip with battery. Even the printer is upgraded to a pulsed power supply mode and the external power supply is cut off, the battery in chip will switch to internal power supply automatically, which reduces the firmware upgrades risk effectively. This is Ninestar’s first protective design on this product.
The second protective design on these products is cartridge structure optimization that prevents chip battery short circuit. Due to the limitation of chip size, the battery must be very tiny on the chip. The very close distance between battery positive and negative will easily trigger battery short circuit. Based on that, Ninestar optimizes toner cartridge structure to further prevent the short circuit risk that may occur during the transportation or use of the chip. The second protective design also set to enhance the product stability.
