Embodiment two

The structural representation of the ink box chip that Fig. 4 provides for the utility model embodiment two, the difference of present embodiment and embodiment one is: monitoring modular 111 comprises quantity of ink monitoring means 111a, reset unit 111b, position monitoring trigger element 111d, change position monitoring means 111e and trigger element 111f is changed in second simulation.Wherein, quantity of ink monitoring means 111a links to each other with the memory 150 of storage print cartridge residual ink amount, perhaps also can link to each other with the sensor of surveying the print cartridge residual ink amount, is used for when monitoring residual ink amount when reaching the setting thresholding, the generation reset signal; Reset unit 111b links to each other with quantity of ink monitoring means 111a, is used for carrying out the ink box chip reset operation according to reset signal; Position monitoring trigger element 111d and reset unit 111b with change position monitoring means 111e and link to each other, be used for when monitoring the complete ink box chip reset operation of reset unit 111b, triggering replacing position monitoring means 111e; Change position monitoring means 111e and link to each other with position monitoring trigger element 111d, whether the monitoring print cartridge arrives and changes the position when being used to be triggered, and produces the position monitoring signal when monitoring print cartridge arrival replacing position; Second simulation is changed trigger element 111f and is linked to each other with handover module 112 with replacing position monitoring means 111e, is used for producing triggering signal according to the position monitoring signal, and triggering signal is sent to handover module 112.

The technical scheme of present embodiment arrives with reset condition and print cartridge and changes the position jointly as the trigger condition that triggers the Plug Action of simulation print cartridge.In the practical application, the trigger condition of changing print cartridge is not limited to this.The so-called position of changing, be print cartridge from the operating position to a crossover position of being extracted fully the printer.Generally can be by opening printer cover, pressing to change the print cartridge button or print cartridge is moved to and change the position by the printers menu option in the computer, in print procedure, print cartridge also can be constantly through changing the position.

The technical scheme of present embodiment moves to the replacing position with chip reset and print cartridge and takes place simultaneously as trigger condition, and the concrete course of work comprises the steps: as shown in Figure 5

Step 510, beginning;

Step 520, printer are finished identification to ink box chip by print cartridge plug testing circuit, promptly judge whether successful connection, if, then beginning to print, execution in step 530 if not, is then returned step 510, lays print cartridge again and discerns once more;

Step 530, in print procedure, printer calculates the residual ink amount of print cartridge, and upgrades the residual ink amount of store memory storage in the ink box chip.Residual ink amount in the ink box chip control module recognition memory, judge whether to satisfy reset condition, be whether residual ink amount is low to moderate the reset gate limit value, if, then can send alarm signal to printer usually, lack China ink with the prompting print cartridge, and execution in step 540, if not, then return execution in step 530, whether monitoring all the time reset condition takes place;

Step 540, ink box chip carry out the parameter reset of ink box chip on the one hand, and produce reset signal, trigger execution in step 550;

Step 550, user may be after receiving alarm mobile print cartridge to changing the position, control module begins to monitor print cartridge and whether arrives the replacing position after getting access to reset signal, if then produce triggering signal and send to handover module, execution in step 560, if not, then do not start the operation of simulation print cartridge plug, can wait for until print cartridge arriving the replacing position, printer still can't recognize the print cartridge plug after waiting for setting-up time, then this flow process finishes, and can be considered needs to change print cartridge;

The handover module of step 560, ink box chip according to triggering signal control first contact and second contact disconnect behind the certain hour closed again, the plug operation of simulation print cartridge.When printer is considered as existing new print cartridge insertion, finish once more and recognize the machine process, then continue execution in step 570;

Step 570, printer are normally printed.

The technical scheme of present embodiment is than the advantage that only resets as the trigger condition technical scheme with ink box chip: the plug operation of simulation print cartridge automatically when ink box chip resets, this scheme is applicable to only needs detector probe place circuit voltage just can confirm the printer that print cartridge plugs.But also needing to detect print cartridge when whether the detection print cartridge plugs, a lot of printers whether reach the replacing position.When adopting the mode of chip reset triggering, printer can report an error usually, to remind the user print cartridge is extracted, and then cooperate the turn-off time of first contact and second contact if the user in time moves to print cartridge the replacing position this moment, then can simulate the Plug Action of print cartridge.

But may there be the situation that the user can't timely mobile print cartridge in the practical application.Present embodiment promptly can address the above problem with the trigger condition that chip reset and position probing plug as the simulation print cartridge simultaneously.When ink box chip resets, at first report an error by printer, when moving to the replacing position with print cartridge, the user triggers closed again plug of simulating print cartridge behind certain hour again with first contact and disconnection back, second contact.The user moves print cartridge, can be by opening printer cover, and perhaps press corresponding button and simply realize, just can finish after waiting for several seconds and simulate the print cartridge Plug Action.
