Description

Technical Field

[0001] The present application relates to the field of printing and imaging, and in particular to a first chip, a communication method, a chip assembly and replaceable accessories. Background Art

[0002] Printers are generally equipped with replaceable accessories. If they are discarded directly, it will pollute the environment. For the sake of environmental protection, third parties will recycle the old consumables and refill them. The data contained in the old consumables chip on the refilled consumables is old data. The ink volume data corresponds to the depleted ink volume and is no longer usable. However, the authentication data contained in the old chip has not changed and is still usable. This is also information that is difficult for third-party manufacturers to replicate in batches.

[0003] There is now a grafted chip that attaches the grafted chip to the old consumable chip and replaces or repairs some of the data in the old chip to achieve similar functions as the OEM new chip, that is, to provide authentication information and accurate ink volume information. Since the printer will download firmware from the Internet from time to time and update its own firmware, in some cases, after the printer system firmware is upgraded, the grafted chip may not be able to correctly process some instructions sent by the printer, or the processing time of these instructions may be too long, exceeding the response time allowed by the printer, etc. Such instructions include confirmation code request instructions sent by the printer, etc. Summary of the invention

[0010] In a possible implementation manner, if the first confirmation code is different from the second confirmation code and the instruction is a first type instruction, the second confirmation code is sent to the printer as the third confirmation code.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0026] In the above description, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0027] As described in the background art, since the response logic of the grafted chip is set for the existing printer instructions, when the printer is connected to the Internet and the firmware is upgraded, it may send new instructions to the chip component. These new instructions are not in the existing instruction set of the grafted chip, and most of the grafted chips cannot process them, thus responding with error codes, while the old chip can process such new instructions. And since the grafted chip reconfigures the old chip, the response of the old chip may not necessarily conform to the current state of the chip component.

[0028] The following describes it in detail with reference to specific embodiments.

[0029] like Figure 1 As shown, a replaceable accessory 200 (i.e., a consumable box) for installation in a host device includes a replaceable accessory 200 box body and a second chip 211. The second chip 211 refers to an original chip installed on the consumable. When the remaining amount of the replaceable accessory 200 is exhausted, the original chip becomes an old chip. The host device and the second chip 211 on the replaceable accessory 200 are connected via a first communication link 201.

[0030] The present application embodiment provides a first chip 212, such as Figure 2 The first chip 212 is used to attach to the second chip 211 to form a chip assembly 210, and the chip assembly 210 is used to be installed in the replaceable accessory 200. The chip assembly 210 is communicatively connected to the host device through the second communication link 202 through the first end of the first chip 212, and the first chip 212 is communicatively connected to the second chip 211 through the third communication link 203 therebetween. The connection method between the first chip 212 and the second chip 211 includes welding and other methods.

[0031] In one case, the printer 100 sends a confirmation code request instruction to the chip component 210, and confirms that the chip can work correctly by identifying the chip's response to the confirmation code request instruction. The confirmation code includes a correct code and an error code. There is only one correct code, while there may be multiple error codes. For example, the data 00 is the correct code, and 01 / 02 / 03... etc. are error codes. Generally, the situations in which error codes are generated include CRC check error, MAC check error, instruction containing illegal address, instruction containing illegal length, instruction execution error, etc., which will generate error codes. In some cases, the chip responds with an error code not because the chip itself cannot work correctly, but because the printer 100 deliberately sends an instruction containing error information to test whether the chip can correctly generate the corresponding error code.

[0032] In most cases, the confirmation codes generated by the first chip 212 and the second chip 211 of the chip assembly 210 are the same. Therefore, in one embodiment of the present application, for most instructions, the chip assembly 210 can determine the confirmation code that the chip needs to reply to the printer 100 in the first step of checking whether the first confirmation code and the second confirmation code are the same. Since the chip's computing power is less consumed when comparing whether the first confirmation code and the second confirmation code are the same, the chip assembly 210 can process the confirmation code request instructions sent continuously by the printer 100 relatively quickly.

[0033] Figure 3Schematic diagram of the communication process of the first chip 212 provided in an embodiment of the present application, the first chip 212 receives the instruction sent by the printer 100, sends the instruction to the second chip 211, receives the second confirmation code generated by the second chip 211, and sends the third confirmation code to the printer 100.

[0034] Specifically, step S301: the host device sends a confirmation code request instruction to the first chip 212 in the chip component 210; step S302: the first chip 212 receives the confirmation code request instruction, generates a first confirmation code, and forwards the first confirmation code to the second chip 211; step S303, the second chip 211 receives the confirmation code request instruction sent by the first chip 212, generates a second confirmation code, and sends the second confirmation code to the first chip 212; step S304, the first chip 212 receives the second confirmation code sent by the second chip 211, and sends the third confirmation code to the printer 100 according to a preset mechanism.

[0035] Specifically, in step S304, the first chip 212 receives the second confirmation code sent by the second chip 211, and sends the third confirmation code to the printer 100 according to the first confirmation code and the second confirmation code, or according to the first confirmation code, the second confirmation code and the instruction type. If the first confirmation code and the second confirmation code are the same, the first chip 212 uses the first confirmation code or the second confirmation code as the third confirmation code sent to the printer 100, and the third error code is the same as the second error code; if the first confirmation code and the second confirmation code are not the same, the instruction received by the first chip 212 is judged again. If the instruction belongs to the first type of instruction, the first type of instruction is an instruction outside the instruction set stored in the first chip 212 (that is, an instruction that the first chip 212 cannot recognize), then the first chip 212 will fail to recognize the instruction, and at this time, the first chip 212 may erroneously reply with a confirmation code, and the second error code generated by the second chip 211 needs to be used as the third error code to the printer 100, and at this time, the third error code is the same as the second error code. If the instruction belongs to the second type of instruction, which is an instruction stored in the instruction set of the first chip 212 (ie, an instruction recognizable by the first chip 212), it is necessary to further determine the type of the instruction.

[0036] Among them, the second type of instructions includes first sub-type instructions, the first sub-type instructions include strong judgment instructions for the first chip 212, and the strong judgment instructions for the first chip 212 refer to instructions that the first chip 212 can independently judge and reply to the confirmation code. When the instruction received by the first chip 212 is the first sub-type instruction, the first confirmation code is used as the third confirmation code sent to the printer 100, and the third confirmation code is different from the second confirmation code; the second type of instructions also includes second sub-type instructions, the second sub-type instructions include weak judgment instructions for the first chip 212, and the weak judgment instructions for the first chip 212 refer to instructions that the first chip 212 cannot confirm what confirmation code should be used to send to the printer 100. When the instruction received by the first chip 212 is the second sub-type instruction, the second confirmation code is used as the third confirmation code sent to the printer 100, and the third confirmation code is the same as the second confirmation code.

[0037] As for how to determine whether an instruction is a strong judgment instruction or a weak judgment instruction, the first chip 212 may preset an identification method, such as marking a part of the instruction set as a strong judgment instruction and another part as a weak judgment instruction, or marking the unmarked part as a weak judgment instruction.

[0038] For example, the second chip 211 stores the installation date, which is written by the printer 100 when the replaceable component including the second chip 211 is first installed in the printer 100. The replaceable component is now in a brand new state. After the installation date data is rewritten by the printer 100 for the first time, the corresponding address becomes a read-only attribute. If the printer 100 writes the address data for the second time, the second chip 211 will report an error. After the second chip 211 is repaired using the first chip 212, the chip component 210 should be in the state of a brand new replaceable component 200. At this time, the chip component 210 should not report an error. Therefore, the instruction is pre-set as a strong judgment instruction in the first chip 212. When the instruction is received, the first chip 212 responds to the printer 100 with a first confirmation code. The state confirmed by this confirmation code is consistent with the current state of the chip component 210 and the replaceable component 200 including the chip component 210.

[0039] In other embodiments of the present application, it is also possible that the confirmation code that the chip needs to reply to the printer 100 does not need to be determined in the first step of checking whether the first confirmation code and the second confirmation code are the same, but the type of printer instruction can be confirmed first. When the first chip 212 confirms that the instruction belongs to an instruction that should generate a confirmation code by the second chip 211, the first chip 212 may not generate the first confirmation code, and directly send the confirmation code generated by the second chip 211 to the printer.

[0040] In other cases, if the confirmation codes generated by the first chip 212 and the second chip 211 are mostly different, according to the above method, the first chip 212 needs to compare whether the first confirmation code and the second confirmation code are the same each time it receives a confirmation code request instruction sent by the printer 100, which requires a large number of judgment processes, wasting a lot of computing power of the first chip 212.

[0041] In view of such a situation, the embodiment of the present application provides a first chip 212, which is used to form a chip assembly 210 with a second chip 211. The chip assembly 210 is used to be installed on the box body of the replaceable accessory 200. The first chip 212 receives the confirmation code request instruction sent by the printer 100, generates a first confirmation code, and sends the confirmation code request instruction to the second chip 211, receives the second confirmation code sent by the second chip 211, and judges the received confirmation code request instruction. If the confirmation code request instruction is the first sub-type instruction in the second type instruction, the first confirmation code is used as the third confirmation code sent to the printer 100, and the third confirmation code is different from the second confirmation code; if the confirmation code request instruction is not the first sub-type instruction in the second type instruction, the second confirmation code is used as the third confirmation code sent to the printer 100, and the third confirmation code is the same as the second confirmation code. For the specific content of the first sub-type instruction in the second type instruction, please refer to the description of the above embodiment. For the sake of brevity, it will not be repeated here.

[0042] The embodiment of the present application provides a chip assembly 210, which is applicable to a replaceable accessory 200. The chip assembly 210 includes a first chip 212 and a second chip 211. For details of the first chip 212 and the second chip 211, please refer to the description of the above embodiment. For the sake of brevity, it will not be repeated here.

For the sake of brevity, it will not be repeated here.
