Main logic circuit module 40 includes Communication Logic module 41 and arranges logic module 42, and chip in normal operation, uses Communication Logic module 41 and ink-jet printer to communicate. When needing ink box chip is configured, then passing through, the logic module 42 data to ink box chip are set and is configured. Generally, before ink box chip dispatches from the factory, the manufacturer of ink box chip requires over and arranges logic module 42 ink box chip is initialized, and as write initial data, and by arranging logic module 42, ink box chip is tested.
Memory module 44 includes communication data memory module 45 and preset data memory module 46, communication data memory module 45 storage has print cartridge and prints relevant data, such as the data such as the authentication data of residual ink amount, the serial number of print cartridge, print cartridge in the model of print cartridge, ink color and print cartridge.

Ink box chip first embodiment:
Referring to Fig. 6, the ink box chip of the present embodiment has main logic circuit module 60, memory module 64 and logic of propositions circuit module 70, main logic circuit module 60 includes Communication Logic module 61 and arranges logic module 62, memory module 64 includes ink headroom data memory module 65 and preset data memory module 66, and wherein preset data memory module 66 includes ink headroom data storage address 67, ink headroom data change condition 68 and ink headroom data preset value 69. Logic of propositions circuit module 70 have judge comparison module 71 and ink headroom data change module 72.
The storage of ink headroom data memory module 65 has the data of ink surplus, and usual ink headroom data is stored on the storage address that ink headroom data memory module 65 is specified, such as address 0x1B. When ink-jet printer communicates with ink box chip, if desired for the data reading ink surplus, sending to ink box chip and read the order of data on the 0x1B of address, the data of address 0x1B are sent to ink-jet printer by ink box chip. Further, after ink-jet printer prints every time, calculate the data of print cartridge inking water surplus, and the ink headroom data of renewal is written on the 0x1B of address.
The stored data in ink headroom data storage address 67 are the data of an address, and this address is exactly the storage address of ink headroom data, i.e. address 0x1B, and therefore the stored data in ink headroom data storage address 67 are address 0x1B.
Such as the print cartridge that print cartridge is normal capacity 90%, then impose a condition as "≤10% ", therefore the ink headroom data change stored content of condition 68 be less than or equal to (≤), ink headroom data preset value 69 is 0x0A, i.e. hexadecimal number 10. Judge that comparison module 71 reads the data of address 0x1B, and judge on the 0x1B of address whether stored data meet and impose a condition, namely≤10%, in this way, ink headroom data change module 72 performs the operation pre-set, and the data of 0x00 is written in the 0x1B of address. When ink-jet printer reads the data of address 0x1B next time, it is judged that in print cartridge, ink exhausts, no longer perform printing.
Ink box chip method of work embodiment:
The workflow of ink box chip is described below in conjunction with Fig. 7. First, ink box chip judges whether to be operated in communication pattern, namely performs step S1. When communicating with ink box chip due to ink-jet printer, sending specific order to ink box chip, ink box chip is by judging whether that receiving specific order judges whether to be operated in communication pattern. As ink box chip is operated in the pattern of setting, the order sent to ink box chip to the equipment of ink box chip write data is different from the order that ink-jet printer sends, or the signal sent to the signal voltage of ink box chip transmission, frequency etc. and ink-jet printer differs. Therefore ink box chip can by judging that order that received signal represents, voltage, frequency etc. judge whether to be operated in communication pattern and still arrange pattern.
As being operated in communication pattern, then perform step S4, otherwise, perform step S2, it may be judged whether be operated in the pattern of setting, as being operated in the pattern of setting, then perform step S3, according to outside order, the stored data of preset data memory module 66 are configured, such as write data or change data.
In step S4, judge that comparison module 71 reads the ink headroom data storage stored data of address 0x1B, and judge that whether the stored data of memory element of this address meet and impose a condition, namely≤10%, in this way, perform module and perform step S5, ink headroom data setting value is written in the 0x1B of address.Ink headroom data setting value is the ink headroom data after change, and in the present embodiment, these data are 0x00.
In step S4, as judged, the ink headroom data storage stored data of address 0x1B are unsatisfactory for imposing a condition, then perform step S6, the data of ink surplus are not modified, according to the command access stored data of ink headroom data memory module 65 that ink-jet printer sends.
Owing to imposing a condition of ink headroom data change is not fixing, but ink headroom data preset value 69 is written in preset data memory module 66, as ink box chip is installed on the print cartridge of normal capacity print cartridge 80%, then passing through, logic module 62 is set ink headroom data preset value 69 is modified as 0x14, judging that comparison module 71 is when judging the ink headroom data storage stored data of address 0x1B less than or equal to 0x14, the data change on the 0x1B of address is become 0x00 by ink headroom data change module 72.
And for example, the data of ink surplus are not exist on the 0x1B of address, and are stored on other address, now without changing logic of propositions circuit module 70, only write new ink headroom data storage address to ink headroom data preset address 67. So, ink box chip can be applied on the print cartridge of dissimilar, different capabilities, and the versatility of ink box chip is good.
Ink box chip the second embodiment:
Referring to Fig. 8, the present embodiment has main logic circuit module 80, memory module 84 and logic of propositions circuit module 90, main logic circuit module 80 includes Communication Logic module 81 and default main logic circuit module 82, memory module 84 has serial number memory module 85 and preset data memory module 86, preset data memory module 86 storage has sequence number detection address 87, presets the data opened new serial number condition 88, preset unlatching value 89, and logic of propositions circuit module 90 includes judging comparison module 91 and choosing new serial number module 92.
Serial number data is organized in serial number memory module 85 storage more, when ink-jet printer communicates with ink box chip, ink box chip exports one group of serial number data by Communication Logic module 81 to ink-jet printer, and ink-jet printer will record the numerical value of ink surplus corresponding to this group serial number data. The data of ink surplus as corresponding in a certain group of serial number data are zero, and ink-jet printer will no longer allow print cartridge corresponding to this group serial number data to be continued to print. Now, ink box chip needs change serial number data one group new and read by ink-jet printer.
Further, once the data of print cartridge surplus are after zero, ink-jet printer is to the special address of ink box chip, as address 0x37 writes the data of a non-zero xFF, therefore, whether it is 0xFF by detecting the data on the 0x37 of address, namely can decide whether to need renewal sequence number. In the present embodiment, the stored data in sequence number detection address 87 are address 0x37, preset open new serial number condition 88 for being not equal to (≠), presetting unlatching, to be worth 89 be 0xFF.
During ink box chip work, it is judged that comparison module 91 judges in the memory element that address 0x37 is corresponding, whether stored data are 0xFF, in this way, represent that ink headroom data is not zero, it is not necessary to change the serial number data to ink-jet printer output. As judged, comparison module 91 judges that in memory element corresponding to address 0x37, stored data are not as 0xFF, represent that ink headroom data is zero, choose new serial number module 92 and from serial number memory module 85, choose serial number data one group new and export to ink-jet printer when ink-jet printer accesses ink box chip.So, ink-jet printer will receive new serial number data, it is ensured that ink-jet printer normal operation.
Once sequence number detection address modification, namely not in use by address 0x37 as sequence number detection address, now have only to write to sequence number detection address 87 data of new sequence number detection address by arranging logic module 82. Or, the default unlatching value that ink-jet printer writes to sequence number detection address is not 0xFF, but other data, can also passing through, logic module 82 is set and writes new data to default unlatching value 89, namely the change of logical judgment condition can be realized, it is not necessary to logic of propositions circuit module 90 is modified.
Ink box chip the 3rd embodiment:
The present embodiment has main logic circuit module 100, memory module 104 and logic of propositions circuit module 110, main logic circuit module 100 includes Communication Logic module 101 and arranges application of logic circuit module 102, memory module 104 has communication data memory module 105 and preset data memory module 106, preset data memory module 106 storage has authentication checks address 107, certification unlocking condition 108, certification unlatching value 109, and logic of propositions circuit module 110 includes judging that comparison module 111 and certification are opened and performs module 112.
Communication data memory module 105 internal memory contains authentication data, part ink-jet printer sends authentication signal to ink box chip when accessing ink box chip, under normal mode of operation, ink box chip needs to ink-jet printer return authentication data, authentication data such as ink-jet printer reception is incorrect or does not receive authentication data, then affect the work of ink-jet printer. Certainly, as ink-jet printer works in a special mode, even if ink box chip receives authentication signal, it is not required that to ink-jet printer return authentication data.
As ink box chip need not to ink-jet printer return authentication data, then write mark data on specific address, such as write data 0x00 on the address 0XFF in communication memory module, as ink box chip needs to ink-jet printer return authentication data, then on the address 0xFF in communication memory module, write data is not 0x00, as long as namely the data of the address 0xFF storage therefore judged in the communication memory module corresponding to authentication checks address can decide whether to need to ink-jet printer return authentication data.
Therefore, in the present embodiment, authentication checks address 107 storage data be exactly address 0xFF, the stored data of certification unlocking condition 108 for equal to (=), it is 0x00 that certification unlatching is worth 109 stored data. During ink box chip work, as received the authentication signal that ink-jet printer sends, judge that comparison module 111 judges whether the stored data of address 0XFF in communication memory module corresponding to authentication checks address 0xFF meet and imposes a condition, namely equal to 0x00, in this way, perform module 112 to send stored for communication data memory module 105 authentication data to ink-jet printer, otherwise, authentication data is not sent to ink-jet printer.
Once authentication checks address or certification unlatching value change, it is only necessary to by arranging interface 102, the stored preset data of preset data memory module 106 is modified, it is not necessary to change logic of propositions circuit module 110, the versatility of ink box chip is good.
Ink box chip the 4th embodiment:
The present embodiment has main logic circuit module 120, memory module 124 and logic of propositions circuit module 130, main logic circuit module 120 includes Communication Logic module 121 and arranges application of logic circuit module 122, memory module 124 has communication data memory module 125 and preset data memory module 126, preset data memory module 126 storage has preset address 127, pre-conditioned 128, preset value 129 and pre-conditioned keying data 135, and logic of propositions circuit module 130 includes judging comparison module 131 and execution module 132.
During ink box chip normal operation, ink-jet printer accesses communication data memory module 125 by Communication Logic module 121, when the stored data of preset data memory module 126 are configured by needs, then passing through, the logic module 122 data to preset data memory module 126 are set and is configured.
Communication data memory module 125 storage has the data of ink surplus, many group serial number data and authentication datas etc., preset address 127 includes multiple address, as ink headroom data stores address, sequence number detection address, authentication checks address etc., pre-conditioned 128 is multiple different verification condition, as more than (>), more than or equal to (>=), less than (<), less than or equal to (≤), equal to (=), be not equal to (≠) etc. different conditions, preset value 129 includes ink headroom data preset value, serial number presets unlatching value, certification unlatching value etc.
Due to preset address 127, pre-conditioned 128 and preset value 129 all include multiple different data, this just constitutes multiple different imposing a condition, each imposes a condition corresponding to the specific function of one, as change ink headroom data, choose new serial number, authentication data transmission whether etc.
During ink box chip work, judge that comparison module 131 reads the stored data of preset address 127 corresponding to the corresponding stored data of memory element of communication data memory module 126, and judge that whether the stored data of this memory element meet and impose a condition, perform module 132 judge these data meet impose a condition after perform corresponding operation, as change ink surplus data, choose new serial number etc. Visible, ink box chip can realize above-mentioned several functions simultaneously.
But, not all of ink box chip all needs to realize above-mentioned several functions, and part ink box chip only needs to realize above-mentioned partial function. Therefore, in the present embodiment, pre-conditioned keying data 135 are the data with multiple byte, and the data of each byte are for representing being turned on and off of a kind of function. The open and close of corresponding function are levied by arranging the numerical value game clock of each byte, such as, when the data of first character joint are 0x00, represent and need change ink headroom data, when the data of first character joint are 0x01, expression need not change ink headroom data, when second byte is 0x00, represents and open the function choosing new serial number, when second byte is 0x01, represent and close the function choosing new serial number, and so on.
Certainly, pre-conditioned keying data 135 can also use a bit binary data to represent the open and close of a kind of function, as used binary number " 0 " to represent the unlatching of a kind of function, uses binary number " 1 " to represent the closedown of a kind of function. So, pre-conditioned keying data 135 only use a byte (8) or two bytes (16) namely can characterize the open and close of multiple difference in functionality.
Owing to pre-conditioned keying data 135 are also stored in preset data memory module 126, therefore can passing through, module 122 is set pre-conditioned keying data 135 are modified, thus controlling the keying of one or more functions.
