The method can be implemented by the consumable chip or the printing consumable, wherein the consumable chip can be configured in the printing consumable, and the consumable chip can be used for matching with a printer to authenticate whether the printing consumable is legal or not, store printing related information and record communication state information of the printing consumable in the printing process.
Fig. 1 is a flowchart of the consumable chip authentication method of the present embodiment, and as shown in fig. 1, the flowchart includes the following steps:
step S101, responding to an authentication request initiated by the printer, sending authentication feedback to the printer, wherein the authentication feedback carries authentication data.
After the printer initiates an authentication request to the consumable chip, the consumable chip identification sends corresponding authentication feedback to the printer according to the authentication request, and the authentication feedback is a feedback message used for instructing the printer to authenticate the consumable chip according to the authentication data. The authentication data may be a single command or a command set in which a plurality of commands are combined. The authentication data may include one or more types of authentication data, wherein the printer may authenticate the consumable chip based on the one or more types of authentication data.
And step S102, receiving a response message returned by the printer in response to the authentication feedback, and judging whether the response message carries a first identifier indicating that the consumable chip is locked.
The response message carries content indicating whether the authentication data is legal or not.
In the first case, in the case that the printer receives only one kind of authentication data, if the authentication data is legal, the response message will carry the content that the consumable chip passes the authentication, otherwise, the response message will carry the content that the consumable chip does not pass the authentication.
And in the second case, under the condition that the printer receives various authentication data, if all the authentication data are legal, the response message carries the content that the consumable chip passes the authentication, otherwise, the response message carries the content that the consumable chip does not pass the authentication.
When the response message carries the content that the consumable chip is not authenticated, in at least one of the two cases, the response message also carries the first identifier that the consumable chip is locked. The first mark is used for indicating the consumable chip to write the consumable chip into a preset zone bit so as to lock the consumable chip and make the printing consumable configured with the consumable chip unavailable.
And step S103, under the condition that the response message is judged to carry the first identifier indicating that the consumable chip is locked, updating authentication data carried by the consumable chip when sending the next authentication feedback.
The updated authentication data can be stored in a certain storage area of the consumable chip in advance, under the condition that the consumable chip receives the first identifier, the consumable chip reads new authentication data from the storage area, the new authentication data is written into the authentication feedback before sending next authentication feedback to the printer so as to replace the old authentication data, and the new authentication data is data which can enable the consumable chip to pass through the printer authentication in the next authentication feedback.
And step S104, receiving a data reading request which is returned by the printer and indicates to read the preset zone bit, sending the first identifier to the printer according to the data reading request, and writing a second identifier in the preset zone bit of the consumable chip before the consumable chip sends the next authentication feedback, wherein the second identifier is used for indicating that the consumable chip is not locked.
The preset zone bit refers to a preset byte in the consumable chip, and the second identifier can be obtained by performing negation operation on the first identifier.
After the printer sends the response message, locking detection is carried out, namely whether the consumable chip writes the first identifier into the preset zone bit according to the indication of the response message is detected, a data reading request for reading the preset zone bit is sent to the consumable chip, if the data sent by the consumable chip is the first identifier, the printer considers that the consumable chip is locked according to the indication, and the printer considers that the consumable chip is unavailable.
This step can be achieved by two embodiments:
writing a second identifier into a preset flag bit of the consumable chip; and receiving a data reading request which is returned by the printer and indicates to read the preset flag bit, and sending the first identifier to the printer according to the data reading request.
That is, after receiving the first identifier returned by the printer, the consumable chip may first store the first identifier in a certain storage area, write the second identifier in the preset flag bit, and read the first identifier from the storage area and send the first identifier to the printer when receiving a data read request indicating to read the preset flag bit returned by the printer.
Writing a first identifier into a preset zone bit of the consumable chip; receiving a data reading request which is returned by the printer and indicates to read a preset zone bit, and sending the data of the preset zone bit to the printer according to the data reading request; and writing a second mark in a preset zone bit of the consumable chip to cover the first mark.
That is, after receiving the first identifier returned by the printer, the consumable chip may write the first identifier into the preset flag bit, and when receiving a data reading request indicating reading of the preset flag bit returned by the printer, read the data (the first identifier) of the preset flag bit, send the read data (the first identifier) to the printer, and then rewrite the data of the preset flag bit into the second identifier.
Both of the above embodiments can avoid the consumable chip being locked and successfully pass the lock detection of the printer in the case where the consumable chip is identified by the printer as being illegal and is to be locked.
Through the steps S101 to S104, under the condition that the consumable chip is identified as illegal by the printer and is to be locked, the first identification is refused to be written or changed into the second identification, the first identification is returned to the printer to be locked and detected through the printer, when the consumable chip receives the authentication request initiated by the printer again, the authentication feedback can be sent to the printer again, so that the printer can authenticate the consumable chip according to the current authentication feedback (carrying the updated authentication data), the authentication can be successfully passed, the problem that the consumable chip is locked and the printing consumable cannot be normally used is solved, and the beneficial effects of preventing the consumable chip from being locked and enabling the printing consumable to be normally used are achieved.
In some of these embodiments, the authentication data comprises first authentication data and second authentication data. The consumable chip firstly sends first authentication data to the printer; generating a first response message after the printer processes the first authentication data, and receiving the first response message returned by the printer in response to the first authentication data by the consumable chip; and in the case that the first response message indicates that the first authentication data is authenticated, sending second authentication data to the printer.
In this embodiment, the consumable chip is carrying out the authentication in-process with the printer, and the consumable sends this two kinds of authentication data for the printer in proper order for this two kinds of data are handled by the printer in proper order, and under the condition that first authentication data pass through printer authentication, the consumable chip sends second authentication data for the printer.
In some embodiments, the printer may store the first authentication data sent by the consumable chip in a preset record list, and if the first authentication data sent by the consumable chip already exists in the preset record list of the printer and the second authentication data fails to pass the printer authentication, the printer will lock the consumable chip, that is, send a response message carrying the first identifier indicating that the consumable chip is locked to the consumable chip. If the first authentication data is not in the preset record list of the printer, the second authentication data has no illegal problem for the printer, namely the consumable chip passes the authentication of the printer.
Further, in the case that the first response message indicates that the first authentication data passes the authentication, after the consumable chip sends the second authentication data to the printer, the printer will generate a second response message after processing the second authentication data, and the consumable chip receives a second response message returned by the printer in response to the second authentication data; the consumable chip judges whether the second response message carries the first identification indicating that the consumable chip is locked or not, and updates first authentication data carried by the consumable chip when next authentication feedback is sent out under the condition that the second response message carries the first identification indicating that the consumable chip is locked.
According to the arrangement, when the consumable chip sends the authentication feedback to the printer again, the updated first authentication data is not in the preset record list of the printer, so that the illegal problem of the second authentication data is eliminated, and the consumable chip passes through the printer authentication.
In some of these embodiments, in the event that the consumable chip and the printer are disconnected from communication and communication is re-established, the printer will initiate an authentication request to the consumable chip, and the consumable chip may again send authentication feedback to the printer in connection with the authentication request.
For example, after the printer accomplishes the locking detection, when the affirmation consumptive material chip is unavailable, only need to cut off the power of printer or printing consumptive material, perhaps break off the communication connection between printer and the printing consumptive material, the printer will authenticate the consumptive material chip again, and the consumptive material chip sends first authentication data and second authentication data again in proper order for the printer promptly, both prevents that the consumptive material chip from being locked, can pass through the authentication of printer again successfully.
Wherein, the power accessible of cutting off printer or printing consumptive material is realized to printer operation switch machine, and the communication connection accessible that breaks between printer and the printing consumptive material is realized to printer operation switch lid.
The method for authenticating the consumable chip is described below with a preferred embodiment.
In a preferred embodiment, the authentication logic between the consumable chip and the printer is:
if the first authentication data fails to authenticate, the second authentication data authentication is not carried out; if the first authentication data is successfully authenticated and the second authentication data is failed to authenticate, the consumable chip is locked; if the first authentication data is successfully authenticated and the second authentication data is successfully authenticated, the consumable chip is successfully authenticated; by modifying the first authentication data so that the first authentication data is different from the data stored in the preset record list of the printer, both the first authentication data and the second authentication data can pass authentication.
The authentication data is illegal by two kinds, i.e., the data itself has an error, and the data itself does not have an error, but does not conform to the expectation of the printer. The invalidity of the authentication data in the present preferred embodiment belongs to the second category.
FIG. 2 is a flowchart of a consumable chip authentication method according to a preferred embodiment of the present application, and as shown in FIG. 2, the flowchart includes the following steps:
step S21, the first authentication data is sent to the printer.
And step S22, receiving a first response message returned by the printer.
And step S23, judging whether the first authentication data passes the authentication according to the first response message. If yes, go to step S24; if not, the flow is ended.
Step S24, the second authentication data is sent to the printer.
And step S25, receiving a second response message returned by the printer.
And step S26, judging whether the second authentication data passes the authentication according to the second response message. If yes, ending the process; if not, step S27 is executed.
