This forms a closed electro-optical feedback loop.
  • a disadvantage of this system is that, for each ink color, the specific color information stored in the control module must match the color of the ink actually contained in the ink cartridge to ensure operability of the printer. Accordingly, it is necessary that control modules must be kept in stock with the appropriate color information or individually programmed. Furthermore, the quality assurance of the ink cartridges requires a corresponding control effort. In addition, if the wrong color information is stored in the control module, an end user can not use an ink cartridge correctly inserted in the printer.

Instead, the control logic unit according to the invention counts the received light emission control signals and controls the light emitting device in accordance with a predetermined algorithm in dependence on the counting sequence. In other words, the light emission control signals provide only one clock, with each individual clock pulse, a pedometer is incremented by one step.
  • the control algorithm specifies a scheme which assigns an action for controlling the light emission device to the respectively current counter reading of the step counter, that is, activates or deactivates the light emission device or preserves the current state (no change of the current state).
  • control modules according to the invention all react identically in a printer, regardless of the cartridge receiving device associated with a color into which they are inserted. Namely, turning on and off is always in accordance with a fixed pattern defined by the control algorithm stored in the control logic unit which is passed in accordance with the sequence of light emission control signals.

In addition, ink cartridges can be used universally, especially in whole families of printer types.
  • At least one control algorithm is installed in the control logic unit of the control module. More preferably, the at least one control algorithm is implemented in the hardware of the control logic unit.

  • the time delay is a period of time that must elapse before the light emitting device is activated upon the arrival of a light emission control signal.
  • the time delay is preferably a fixed time delay for a printer type and / or for a family of printer types.
  • the essential difference of the prior art control module according to the invention is that the light emission control circuit basically recognizes and detects all occurring light emission control signals independently of color information (color ID) contained therein. In other words, the light emission control circuit does not respond to color-specific light emission control signals, whereby the light emission device connected to the light emission control circuit is also activated or deactivated independently of the color ID transmitted from the printer. Thus, it is advantageously not necessary to deposit such color information in the control module. Furthermore, advantageously, a control module having a single configuration can be used for any ink color.
  • the occurrence of false positive short circuit messages is advantageously prevented or at least reduced when multiple ink cartridges are used in a printer.
  • Printers regularly monitor the power consumption of the ink cartridges, for example by means of a tester, in order to be able to shut off, for example, the supply voltage for the ink cartridges when possible short circuits occur.

If the system clock of a first printer differs from that of a second printer, then the control module according to the invention in the two printers would perform the activation of the light-emitting device with different time delays. Conversely, the system clock would have to be determined for each printer model and a control module adapted to it would be provided. If the control module according to the invention is set up to determine the period of the system clock of the printer, then the adaptation in this regard is advantageously eliminated. More preferably, the light emission control means of the control module is arranged to determine the period of the system clock of the printer.
  • the determination of the period of the system clock of the printer takes place after the onset of the control module in the printer and / or during the initialization phase of the printer.
  • Printers known in the art undergo an initialization phase when inserting a new ink cartridge, within which, for example, the correct insertion of the cartridge and / or the correct contacting of the contact elements is checked with the printer control buses and / or the power consumption of the ink cartridge.
  • a determination of the period of the system clock of the printer during this initialization phase has the advantage that at this time the ink cartridge is not yet used for printing.

More preferably, to determine the period of the system clock of the printer during the standardized action of the printer of known duration, the system clock of the printer is determined and / or measured. In other words, the control module according to the invention counts the system clock signals of the printer over the duration of the standardized action. After that, simply the frequency of the system clock can be calculated. Particularly preferred among a printer type or a family of printer types one or a plurality of printers understood that have an identical standardized action with a known period of time.
  • the standardized action of the printer of known duration is the amount of time between a first printer control signal transmitted by the printer and a second printer control signal transmitted by the printer.
