  • Type of imaging cartridge chips and methods for responding to read/write consumable volume information in an imaging device
    Patent number: 10350900
    Abstract: A method for responding to read/write consumable volume information in an imaging device.
    Type: Grant
    Filed: July 17, 2017

  • Method for controlling light emission of ink cartridge and control unit, circuit board, ink cartridge, and imaging device
    Patent number: 9834003
    Abstract: The present invention provides a method for controlling light emission of an ink cartridge, a control unit, a circuit board, an ink cartridge and an imaging device, to decrease misjudgment rate of the imaging device. The control method includes: receiving and identifying a light emitting control instruction from the imaging device main body; starting a light-on delay timing when identifying the light emitting control instruction is a light-on instruction; controlling the light emitting unit of the ink cartridge to stop emitting light when identifying the light emitting control instruction is a light-off instruction; controlling the light emitting unit to emit light when detecting a timing value of the light-on delay timing reaches a delay threshold value. The present invention avoids misjudgment problem of unable to pass position detection due to light amount inconsistent caused by manufacturing errors of the light emitting unit, when setting a light-on delay timing.
