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.
