  • An ink cartridge with an electronic module and a light emitting device is known.
  • an ink cartridge set consisting of several different types of cartridges (ink cartridges having different characteristics, such as ink color, type or amount) is used.
  • the printer has a bus that consists of lines for power and serial data transmission.
  • the electronic modules of the ink cartridges are connected to the bus via electrical contacts.
  • a code for the cartridge type of the respective ink cartridge is stored in the electronic module. This code serves as the address of the ink cartridge, through which the ink cartridge on the bus can be selectively controlled.
  • a check is made as to whether the ink cartridges are positioned at the position intended for the particular cartridge type in the printer.
  • a light sensor is provided on the printer side, opposite to the in the printer in the form of an ink cartridge set located ink cartridges are positioned one after the other. During this process, the light emitting devices of the ink cartridges are driven by the printer.
  • the control takes place via the address of the respective ink cartridge to be controlled.
  • the light emitting device of the selected or driven ink cartridge emits light. If the light emission device of the ink cartridge located opposite the light sensor emits light, the light sensor detects the emitted light. The printer thus recognizes that the correct position is the correct ink cartridge, ie the ink cartridge with the cartridge type associated with the checked position. If the light emission device emits light from another ink cartridge, which is not located above the light sensor, the light sensor does not detect the emitted light. In this case, since the light sensor does not detect light, the printer recognizes that the correct position is not the correct ink cartridge, ie the ink cartridge with the cartridge type associated with the checked position.
  • the adverse effect occurs that stray light from flashing ink cartridges adjacent to the ink cartridge set can be detected by the light sensor. If, for example, instead of the ink cartridge located opposite the light sensor, the adjacent ink cartridge emits light, the light sensor could detect components of this light in the form of scattered light. Consequently, the printer would erroneously detect a presence of the driven ink cartridge at the position above the light sensor and assume proper positioning of the ink cartridge in the printer.
  • Another disadvantageous effect is that due to the selective driving of the ink cartridges on the address of the respective ink cartridge to be controlled on the traffic The bus can sometimes be high. This high traffic on the bus can lead to an increased error rate in the serial data transmission between the printer and the ink cartridge.
  • the present invention has been made in light of the above-described prior art, and it is an object of the present invention to provide an ink cartridge and an ink cartridge set in which erroneous detection due to stray light as described above does not occur.
