[0002] 本发明所说的成像设备是指将文字、图案等电信号转换为在纸张等介质上形成可视图像的设备,例如喷墨类或激光类的打印机、复印机、传真机及多功能一体机。 [0002] The image forming apparatus according to the present invention, said means converts the electrical signal text, graphics and other equipment for the visible image formed on the medium such as paper, for example, an ink jet type or laser type printers, copy machines, fax machines and multi-function One machine.

[0003] 常用的两类打印机是喷墨打印机和激光打印机,喷墨打印机使用容纳有墨水的墨盒作为耗材容器向打印机提供打印用的墨水,以在纸张上形成需要打印的文字或图案;激光打印机则使用容纳有碳粉的碳粉盒作为耗材容器向打印机提供打印用的碳粉,以在介质上形成需要打印的文字或图案,复印机、传真机及多功能一体机的成像原理、使用耗材容器等与打印机基本相同。 [0003] The two types of printers used is an inkjet printer and a laser printer, an inkjet printer uses ink cartridge containing a consumable container for providing ink for printing to the printer to be printed to form text or images on paper; laser printer using the toner cartridge containing a consumable container to provide toner for printing to the printer to image formation principle on a medium to be printed text or images, copiers, fax machines, and multifunction machines, the use of consumable container substantially the same as the other printers. 本发明所说的耗材是指墨水或碳粉,通用芯片的通信方法是指该通用芯片安装在耗材容器上,当耗材容器安装到成像设备上进行工作时,通用芯片与成像设备主控制器之间进行的通信方法。 The present invention refers to said consumable ink or toner, a communication method GM chip is the chip is mounted on the common consumables container, when the container is mounted to the consumable working on the image forming apparatus, the image forming apparatus main chip and common controllers the communication method performed between.

[0004] 耗材容器的壳体上一般都安装有耗材芯片10,耗材芯片10结构如图1所示,其包括有一块基板11,在基板上设置有电子模块12,电子模块中包括有接收成像设备信号及电能的通信单元和实现与成像设备之间通信的集成电路部分,通信单元可以是感应线圈或触点,集成电路部分中一般设置有一控制单元、一存储单元和一接口单元,该存储单元存储与耗材容器相关的信息,包括参数信息和计量信息,参数信息包括:耗材容器型号、耗材颜色、 耗材总打印量、适用的成像设备型号等信息,计量信息包括:耗材剩余量、打印页数等信息, 该控制单元实现存储单元内数据的存取,该接口单元为耗材芯片及成像设备通信提供接口或协议。 [0004] The upper case is generally installed consumable container consumables chip 10, chip 10 supplies the structure shown in FIG., Which includes a substrate 11, the substrate 12 is provided with an electronic module, the electronic module 1 with a receiving comprises forming integrated circuit portion and communication signals between the power devices and communication unit implemented with the imaging apparatus, the communication unit may be an induction coil or contacts, an integrated circuit is provided with a generally part of a control unit, a memory unit and an interface unit, the memory unit stores a consumable container-related information, including parameter information and metering information, parameter information comprising: a consumable container type, color of the supply, supplies a total print volume for the image forming apparatus models and other information, the measurement information comprises: a remainder of the consumable, the printed page number and other information, which control unit implements the memory access unit data, the interface unit provides a communication interface or protocol chip and supplies the image forming apparatus.

[0005] 成像设备访问耗材芯片10时,首先对耗材芯片进行验证,以验证耗材芯片的密钥是否正确,即首先由成像设备向耗材芯片10发送一组密钥认证命令,耗材芯片10收到该认证命令后,取出附着在认证命令中的数据与耗材芯片10内部的密码算法进行运算得到一组密钥认证信息,然后,耗材芯片10向成像设备返回该算好的密钥认证信息,成像设备根据收到的信息来判断该耗材芯片10的合法性,若该耗材芯片10合法,则对匹配的耗材芯片10进行读或写存储器的操作,否则,成像设备提示出错或不匹配的信息。 [0005] The imaging apparatus supplies access to the chip 10, the first chip to authenticate consumables, consumables chip key to verify the correct, i.e., a first set of transmission key authentication chip 10 supplies commands to the image forming apparatus, the chip 10 supplies received after the authentication command, remove the encryption algorithm is attached inside the authentication command and supplies the data to obtain the chip 10 computes a set of authentication key information, and then, the chip 10 supplies the image forming apparatus returns to the key authentication information is quite good, imaging device according to the information received to determine the legality of the chip 10 supplies, if the chip 10 supplies valid, the matching chip 10 supplies a read or write operation of the memory, otherwise, an error message or the image forming apparatus does not match.

[0006] 例如:一般情况下,A款打印机发送的密钥认证命令为:“2B8A…”,其中:“0X2B” 为密钥认证命令,“8A”为密钥认证码,“…”为密钥认证码随机数据组的其它值,若密钥认证码相同,该其他值数据也相同,A款打印机的耗材芯片接收到该命令和数据后,经计算得出并返回密钥认证信息为:“2B30…”,A款打印机接收到该返回的密钥认证信息后,经确认,该耗材芯片返回的密码认证信息是合法的,因此,该款打印机可对该耗材芯片的存储器进行读写操作。 [0006] For example: In general, A-key authentication command transmitted to the printer section: "The antibody reacted to ...", where: "0x2B" as the key authentication command ". 8A" is a key authentication code, "..." as the secret other keys authentication code value of the random data set, if the same key authentication code, the other data is the same value, a paragraph printer supplies chip receiving the command and the data, and calculated by the key authentication information is returned: "2B30 ...", section a printer after receiving the information returned by the authentication key, is confirmed, the password authentication information returned consumable chip is legitimate, therefore, this printer can read and write the memory chip supplies . 与此相似,B款打印机密钥认证命令为:“2BE8…”,B款打印机的耗材芯片接收到该命令和数据后,计算得出并返回密钥认证信息为:“2B74…”,B款打印机接收到该信息后,经确认,该耗材芯片返回的密码认证信息是合法的,因此,可对该耗材芯片的存储器进行读写操作。 Similarly, B-key authentication command to the printer section: "2BE8 ...", B paragraph printer supplies chip receiving the command and the data, and returns the calculated key authentication information: "2B74 ...", B section When the printer receives the information is confirmed, the password authentication information returned consumable chip is legal, thus, can read and write the memory chip supplies.

[0007] 通常,打印机发出的密钥认证命令的格式是相同的,即:1字节密钥认证命令+密钥认证随机数据组,同款打印机的密钥认证相同,即:相同打印机型号的密钥认证请求信息是一样的,利用这个特点,许多厂家采用各种方法来获取认证码以制造通用于各款打印机类型的通用芯片,一般方法是:获取1字节的密钥认证信息以进行认证匹配,有些厂家还在芯片中设置一个数据采集单元,用于采集密钥认证命令(如:“0X2B”)后的某一个字节,以便于打印机进行认证匹配,例如:可以选择密钥认证命令后的第一字节,如A款打印机选择“0X8A”,而B款打印机选择“0XE8”,应用该方法,可以制造通用于各款打印机的耗材芯片一一通用芯片;然而,随着打印机型号的日益增多,密钥认证随机信息不可避免会出现交叉的情况,如果仍然采用上述的方法来进行通用 [0007] Generally, the format of the key authentication command issued by a printer is the same, namely: an authentication command byte key + key authentication of random data set, the same as the printer section authentication key, namely: the same printer model key authentication request message is the same, use of this feature, many manufacturers use various methods to obtain the authentication code sections in the printer to produce a common type of general purpose chip, the general approach is: 1 byte acquiring key information for authentication matching authentication, some chip manufacturers also provided a data acquisition unit for acquiring key authentication command (eg: "0X2B") of one byte, for authentication matching printer, for example: the authentication key may be selected the first byte of the command, such as a printer selection section a "0X8A", the printer selection section B "0XE8", application of this method, can be produced in the common sections of the chip supplies the printer one by one common chip; however, as the printer models growing, key authentication random information unavoidable circumstances cross will appear, if still using the above approach to generic 芯片认证,往往会出现通用芯片选择打印机型号混乱的情况,导致打印机不能识别所安装碳粉盒上的通用芯片,出现打印机报错,使得碳粉盒无法继续使用;而且,由于采用该方法所制造的通用芯片中设置有适合多款打印机的信息,设置有该通用芯片的耗材容器在某款打印机上使用完毕后,再安装到另一款打印机上使用时,因通用芯片对应的另一款打印机芯片信息未被使用过,信息仍全新,则会出现打印机提示该耗材容器仍可使用的情况,而实际上,该耗材容器中的耗材已经用完,已不能在另一台打印机上继续使用,若该通用芯片适用于N款打印机,则该通用芯片具有N个寿命,如此,给用户的使用带来不便。 Authentication chip, the chip select universal often appear printer model confusion, cause the printer does not recognize the common chip mounted on the toner cartridge, the printer error occurs, so that the cartridge can not continue; Further, since the manufacturing method when the chip is provided with a general-purpose information for a variety of printers, the universal chip provided consumable container after use on a section of the printer, and then mounted on another printer to use, due to the common chip corresponding to another printer chip information is not used, the information is still new, the printer prompts the consumable container can still use appears, in fact, the consumable container supplies have run out, can not continue to use it on another printer, if the universal chip for your printer to N, then the generic chip has N life, thus, to the user's inconvenience.

[0037] 由上可见,E款激光打印机的密钥认证信息、A款激光打印机的密钥认证信息以及D款激光打印机的密钥认证信息交叉,即A款激光打印机的钥认证信息和D款激光打印机的密钥认证信息是E款激光打印机的密钥认证信息的一部分;B款激光打印机的密钥认证信息与C款激光打印机的密钥认证信息也交叉,即B款激光打印机的密钥认证信息是C款激光打印机的密钥认证信息的一部分。 [0037] As seen above, the key authentication information, the laser printer section E, the key authentication information and the key authentication information A cross section of the laser printer section D laser printer, i.e. laser printer section A of the authentication information and the key section D key authentication information is part of a laser printer key authentication information of the laser printer section E; B section of the laser printer key authentication information with the key authentication information C are also cross-section of a laser printer, i.e., a key section of a laser printer B the authentication information is a key part of the laser printer authentication information in paragraph C. 若采用现有的通用芯片及通信方法来对激光打印机选型,会出现型号混乱现象,从而导致由于认证信息交叉而出现通用芯片选择激光打印机型号出错的问题。 If the use of existing general-purpose chip and communication method for laser printer selection, there will be confusion model, because the authentication information leading to the emergence of general-purpose chip select cross laser printer model error problem.

[0038] 本实施例所提供的通用芯片可解决上述问题。 Universal chip [0038] This embodiment solves the above problems is provided. 本实施例之通用芯片的存储单元中,存储有H系列品牌激光打印机(包括A款激光打印机、B款激光打印机、C款激光打印机和D款激光打印机)和C系列品牌打印机(如E款激光打印机)等激光打印机的信息,即激光打印机型号信息和数据信息,激光打印机密钥认证命令均为0X2B,本实施例采用数据采集单元取出认证命令0X2B后的第一个字节,也可以取出其后的任意字节或校验字节;然后, 状态机选型单元根据激光打印机输入的认证命令及通用芯片所处的数据操作状态来确定激光打印机型号,若该通用芯片目前处于读信息或写信息状态,则当前选型的激光打印机型号为该通用芯片所对应的激光打印机型号信息,该激光打印机型号信息为对应的参数信息和计量信息,具体说,如果确定是A款激光打印机,则选定A款激光打印机的信息数据,该通用芯片使用A款激光打印 The storage unit universal chip according to the present embodiment stores a H series brand laser beam printer (including A, paragraph laser printer, B paragraph laser printers, C models of laser printers and D models of laser printers) and C Series brand printers (such as E paragraph Laser the printer information), such as laser printer, i.e. laser printer models and data information, laser printers are 0x2B key authentication command, the present embodiment employs a data acquisition unit out of the first byte after the authentication of the command 0x2B, which may be removed after any bytes or check bytes; then, the state machine selection unit determines the type laser printer laser printer according to the input commands and data authentication operation state in which the common chip, if the write current in a general-purpose chip or reading information status information, the current models of laser printer laser printer model selection information corresponding for the general-purpose chip, the laser printer model information corresponding to the parameter information and metering information, specifically, section a is determined if the laser printer is selected from a given information data section of the laser printer, the universal chip using a laser printing section a 所对应的信息数据与A款激光打印机进行通信,如果确定是E款激光打印机,则选定E款激光打印机的信息数据,该通用芯片使用E款激光打印机的信息数据与E款激光打印机进行通信,其他类型激光打印机的选型原理同上,因此,采用上述结构,可以使得通用芯片通用于各型号的激光打印机,且不会出现激光打印机型号选择混乱的问题。 Information data corresponding to communicate with the laser printer section A, subsection E is determined if the laser printer, the laser printer under E message data is selected, the information data using the generic-chip laser printer section E and section E laser printer communication selection principle other types of laser printers above, therefore, the above structure, can cause a general purpose chip common to all models of laser printer and laser printer models will not be selected confusing problem.

[0039] 如图5,本实施例之通用芯片状态机选型单元的工作过程如下: Working Process [0039] FIG. 5, the state machine of the present embodiment of the general-purpose chip selection unit embodiment is as follows:

IDLE (空闲)状态:该状态是激光打印机给通用芯片上电,准备对通用芯片进行数据操作的状态;或激光打印机开始对通用芯片存储单元进行读命令操作或写命令操作(Read/ Write)的状态;上述两种状态定义为IDLE状态,通用芯片在IDLE状态下可重新进行选型。 IDLE (idle) state: This state is a laser printer to power on a common chip, ready for universal chip data operation status; or a laser printer starts common chip memory cell read command or write command operation (Read / Write) of state; the two state is defined as the IDLE state, re-selection of common chip in the IDLE state.

[0040] 通用芯片进入IDLE后,若激光打印机对通用芯片输入0X9F的认证命令,则通用芯片状态机选型单元选型为C款激光打印机型号信息,此时,若激光打印机对通用芯片进行Read/Write操作则状态机选型单元回到IDLE状态,此后,激光打印机对通用芯片执行的所有Read/Write操作都是此时通用芯片状态机选型单元所选定型号对应的C款激光打印机型号信息。 [0040] The general-purpose chip into the IDLE, if a laser printer to enter an authentication command 0X9F common chip, the chip selection unit selection state machine is universal in paragraph C of laser printer model information, at this time, if the laser printer for common chip Read / Write operation of the state machine back to the IDLE state selection unit, and thereafter, the laser printer for common chip performs all the Read / Write operations are common chip at this time the state machine model selection unit corresponding to the laser printer section C model Selection information. 如状态机选型单元当前选型为C款激光打印机型号,但又未进行过Read/Write 操作,则后续再输入0X9F认证命令或0XE8认证命令,此时通用芯片状态机选型都为C款激光打印机型号信息。 The state machine selection unit C under a current selection is a laser printer models, but have not been Read / Write operation, the subsequent re-authentication command or input 0X9F 0XE8 authentication command, and the common chip selection state machine models are C laser printer model information. 通用芯片进入IDLE后,若打印机直接对芯片输入0XE8的认证命令,则通用芯片状态机选型单元的选型为B款激光打印机型号信息,此后,即使打印机多次输入0XE8的认证命令,通用芯片状态机选型单元的选型仍然维持为B款激光打印机型号信息, 直到激光打印机对通用芯片执行Read/Write操作,使得通用芯片回到IDLE状态方可进行下一次选型。 After the general-purpose chip into the IDLE, if the printer directly to the chip selection input 0XE8 authentication command, the generic-chip state machine selection unit for laser printer section B model information, thereafter, even if the printer 0XE8 input multiple authentication command, generic chip Dimensioning the state machine remains in the unit for the laser printer section B model information, until the laser printer for common chip performs Read / Write operation, so that only common chip back to the IDLE state at once selection. 通用芯片进入IDLE后,若打印机对通用芯片输入0XE6的认证命令,状态机选型单元的选型为D款激光打印机型号信息,此时若激光打印机对通用芯片执行Read/Write 操作,则通用芯片回到IDLE状态,此后激光打印机对通用芯片执行的所有Read/Write操作都是此时通用芯片状态机选型单元所选定型号对应的D款激光打印机型号信息;如状态机选型单元当前选型为D款激光打印机型号,但又未进行过Read/Write操作,即使激光打印机多次输入0XE6的认证命令,通用芯片状态机选型单元的选型仍维持为D款激光打印机型号信息,若此时激光打印机输入0X8A的认证命令,此时通用芯片状态机选型单元的选型为E款型号信息,后续即使激光打印机再多次输入0X8A的认证命令,该通用芯片状态机选型单元的选型仍维持为E款激光打印机型号信息。 General-purpose chip into the IDLE, if the printer to enter an authentication command 0XE6 common chip, the state machine selection unit for selection of laser printer section D model information, at this time if a laser beam printer for performing general-purpose chip Read / Write operation, the universal chip back to the IDLE state after all of the laser printer for common chip performs a Read / Write operations are common chip at this time the state machine selection unit section D laser printer model information corresponding to the selected model; state machine currently selected selection means type D models of laser printer models, but have not been Read / Write operation, the laser printer even if multiple input 0XE6 authentication command, the state machine selection common chip selection unit remains to subsection D laser printer model information, if At this time, the laser printer input 0X8A authentication command, and the common chip selection state machine selection models of E units of information, even when the laser printer and enter a subsequent 0X8A authentication command repeatedly, the generic-chip state machine selection unit Selection of the E models remained laser printer model information. 进入IDLE后,若激光打印机输入0X8A 的认证命令,则通用芯片状态机选型单元的选型为A款激光打印机型号信息,此后激光打印机多次输入0X8A的认证命令,选型仍维持为A款激光打印机型号信息,直到激光打印机对通用芯片执行Read/Write操作,通用芯片回到IDLE状态时,才能进行下一次的选型。 After entering IDLE, if the laser printer selection input 0X8A authentication command, the generic-chip state machine selection unit for paragraph A laser printer model information, after laser printer input 0X8A authentication command repeatedly to selection remained subsection A laser printer model information, until the laser printer for general-purpose chip performs Read / Write operations, general-purpose chip Back IDLE state, in order to carry out the next selection. [0041] 由于大部分激光打印机对通用芯片执行操作时,一般先给通用芯片上电,然后再发密钥认证命令进行认证,如果通用芯片合法,则进行读通用芯片存储器操作或写芯片存储器操作以执行打印,从而起到碳粉盒使用过程的状态记录作用,因此,本发明通用芯片实施例采用在被激光打印机读写存储器操作时取当前状态机选型单元所确定的激光打印机型号,可以保证通用芯片正确地选择对应的型号。 [0041] Since most of the laser printer when performing general operation of the chip, generally give a general-purpose chip electrically, and then send the authentication key authentication command, if the general-purpose chip method, a general-purpose on-chip memory is a read or write operation of the memory chip to record the effect of the state printing is performed using the thus play process cartridge, and therefore, the present invention embodiment common chip take the current embodiment employs a state machine selection unit determines the laser printer models when the memory write operation of the laser printer, can be ensure universal chip correctly select the corresponding model. 上述状态机选型示例图只是本实施利的一种举例,其选型逻辑可以根据实际需要重新设定。 FIG selection state machine described above is only exemplary of the present embodiment example a benefit which the selection logic can be reset as required.

[0044] 作为本发明通用芯片实施例的又一种变换,用量检测单元检测已打印量的值可以根据实际情况预先设置,即可以是取值为2〜100中的任一整数或小数,该变换同样可以实现本发明的目的;因碳粉在打印过程中实际消耗往往与通用芯片有偏差,而对于实际碳粉量,激光打印机可以检测出其碳粉量接近消耗完称之为粉量低,也可检测出其碳粉消耗完称之为粉量尽,激光打印机一般也有提示粉量低和提示粉量尽的功能,且在通用芯片存储单元中记录,用量检测单元也可以通过检测粉量低或粉量尽信息来提供锁定信号给型号锁定单元进行型号锁定的依据,上述变换同样可以实现本发明的目的。 [0044] As a general embodiment of the present invention the chip still another embodiment of the conversion, an amount value detection unit detects the amount printed in advance may be set according to the actual situation, i.e. the value of may be any integer or decimal 2~100, the transformation can also achieve the object of the present invention; toner in the printing process because the actual consumption tends to General chip offset, and the actual amount of toner, the laser printer can detect the amount of toner which is consumed nearly called low amount of powder , which may also be referred to detect the amount of toner consumed to make powder, laser printers generally have a low amount of powder tips and tips to make the amount of functional powder, and recorded in the general-purpose chip memory unit, the detection unit may also be an amount detected by powder low or the amount of powder to make the information signal to provide a locking means for locking depending on the model type of lock, the above object of the present invention the same conversion can be achieved.

[0045] 作为本发明通用芯片实施例的又一种变换,该通用芯片还可以是应用于墨盒上的通用芯片,其存储单元中存储的是与墨盒及墨水相关的信息,该墨盒通用芯片可以通用于芯片中所存储类型所对应的喷墨打印机。 [0045] As a general embodiment of the present invention the chip still another embodiment of the conversion, the common chip may also be applied to a common chip on the ink cartridge, which is stored in the storage unit associated with the ink cartridges and the information, the universal cartridge chip may common to the chip corresponding to the type of ink jet printer memory.
