With reference to figure 1, show the flow chart of the method embodiment 1 that a kind of control data of the present invention writes, can may further comprise the steps:
Step 101: obtain the revised target data information that imaging device sends to imaging box chip.
In embodiments of the present invention, describe with the example of printer as imaging device.When printer detects the property abnormality of some assembly; For example the magnitude of voltage of powder feeding roller or developer roll is unusual; Or made printer receive that the data (for example sequence number or check bit etc.) of chip transmission have deviation owing to disturbing in the process of printer and chip communication; Printer will take in the imaging box does not have consumptive material or chip not to match, and printer will be rewritten some data in the chip, for example consumptive material use amount, sequence number or check bit etc.This moment, printer sent revised target data information to imaging box chip.For example, when needs were rewritten the consumptive material use amount, revised target data information was promptly represented the revised numerical value of consumptive material use amount.
Step 102: judge whether said target data information is illegal, if then get into step 103, if not, then get into step 104.
When imaging box chip detection when target data information is arranged, first and whether illegally judge this target data information.If this target data information is illegal; Explain that it is maloperation that printer sends target data information; Need not receive the rewriting numerical value shown in this target data information indication this moment; Could solve like this at printer owing to disturbed or flase drop measures under the situation of property abnormality of assembly, the product resource waste problem that is caused.
Step 103: refusal writes said target data information.
Promptly be the operation that said target data information refusal is write by imaging box chip in this step, for example, the initial data that keeps in the imaging box chip is constant, does not perhaps preserve said target data information etc.; Thereby the non-print machine writes any data toward the memory cell of imaging box chip.
With reference to shown in Figure 2, said step 103 specifically can may further comprise the steps in the process of implementation:
Step 201: said target data information is saved in the volatile memory.
When the target data information of judging printer be written as illegal operation the time; Target data information that then can a printer receives; But need to stop it revised target data information to be write the memory cell of chip; The data that perhaps, can only need write printer exist in the cache register.
Concrete, the memory cell of this chip can be made up of volatile memory and nonvolatile memory.Wherein volatile memory can comprise RAM (Random Access Memor; Random access memory); Nonvolatile memory can comprise EEPROM (Electrically Erasable Programmable Read-Only Memory; EEPROM), when the target data information of judging printer when being illegal, then memory cell can only be temporarily stored in target data information in the volatile memory.
Step 202: stop said target data information unloading to nonvolatile memory.
And memory cell need stop target data information to dump to the nonvolatile memory from volatile memory, like this, can guarantee the normal storage of printer and imaging box chip, can guarantee that again the continuation of chip is used.
Step 104: carry out data rewriting operation to said imaging box chip according to target data information.
When obtaining said target data information when legal, then directly normally write said target data, promptly be to carry out data rewriting operation to said imaging box chip according to target data information.
In the present embodiment; Through judging whether imaging device is illegal to the target data information that sends in the imaging box chip; And when this target data information was illegal, the refusal imaging device covered the initial data in the imaging box chip, and perhaps refusal is preserved said target data information; Thereby can be when printer be unusual to the Performance Detection of assembly; Also can keep the operate as normal of imaging device and imaging box chip, imaging device writes the problem of data to the imaging box chip mistake in the prior art thereby solved, and then can practice thrift product resource.

Step 301: obtain the revised target data information that imaging device sends to imaging box chip.
The execution of this step by the agency of in embodiment 1 repeats no more at this.
Step 302: when the consumptive material use amount was revised in said target data information indication, whether judgment formula Δ TL＞(Δ PC/ standard life-span * 20) set up, if; Then get into step 303, if not, then get into step 304; Wherein, Said Δ TL is the consumptive material use amount, and said Δ PC is the number of pages of current printing, and the said standard life-span is the imaging spendable life-span of box under 5% the coverage rate.
In practical application, it is to calculate according to 5% coverage rate that general printer calculates the consumptive material use amount, and coverage rate is meant that the document black print that printer prints goes out accounts for white edition percentage.For example, if the user has printed 1 page, the scope of the consumptive material use amount that normal printer calculates is: greater than the employed consumable quantity of 5% coverage rate less than the employed consumable quantity of 100% coverage rate.If printer exceeds this scope to the rewriting of the consumptive material use amount in the imaging box chip after the user has printed 1 page, can think that then this rewriting operation is undesired.
Use Δ TL＞(Δ PC/ standard life-span * 20) formula to judge in the present embodiment; Wherein, Δ TL is consumptive material use amount (%); Δ PC is the number of pages (%) of this printing, and the standard life-span is the imaging spendable life-span of box under 5% the coverage rate, and then (Δ PC/ standard life-span) * 20 expression coverage rates are the number of pages of this printing under 100% the situation.If the consumptive material use amount that this printer writes chip, thinks then that the target data information of this printer is illegal greater than the employed consumptive material use amount of the number of pages of this printing under 100% coverage rate.For example, this number of print pages is 20 pages, and the standard life-span of imaging box is 4000 pages; Then 20 pages consume (20/4000) * 20 at most; Promptly 10% consumptive material use amount as if consumptive material use amount＞10% that printer will write, can think that then this target data information is illegal.
Step 303: refusal writes said target data information.
During to the target data information of consumptive material use amount, need refusal write said target data information at printer.
Step 304: carry out data rewriting operation to said imaging box chip according to target data information.
When printer is legal to the target data information of consumptive material use amount, need normally carry out the rewriting operation of consumptive material use amount according to the represented numerical value of target data information.
In the present embodiment; Through judging whether imaging device is illegal to the target data information of the consumptive material use amount in the imaging box chip; And when this target data information is illegal; The refusal imaging device is rewritten the consumptive material use amount in the imaging box chip, thereby can when printer is unusual to the unusual Performance Detection of the magnitude of voltage of powder feeding roller or developer roll, also can keep the operate as normal of imaging device and imaging box chip; Imaging device writes the problem of data to the imaging box chip mistake in the prior art thereby solved, and then can practice thrift product resource.
With reference to figure 4, show the flow chart of the method embodiment 3 that a kind of control data of the present invention writes, present embodiment can may further comprise the steps:
Step 401: be predisposed to machine used or read-write number of times as the box chip.
In the present embodiment, need in imaging box chip, to be provided with in advance available on machine number of times or read-write number of times, for machine number of times in total use of this imaging box chip or read and write number of times.
Step 402: obtain the revised target data information that imaging device sends to imaging box chip.
Step 403: judge that in fact whether machine or read-write number of times are less than using machine or read-write number of times, if then get into step 404, if not, then get into step 405.
In the present embodiment, specifically can realize the implementation of this step through a data comparator, specifically promptly be that the in fact machine number of times of this imaging box chip that gets access to or the machine used or the read-write number of times of read-write number of times and setting are in advance compared.To rewrite information such as the sequence number of imaging box chip or check bit at printer; Imaging box chip no longer is applicable under the situation of printer; Can go up the judgement of machine number of times or read-write number of times by data comparator; If in fact machine number of times or read-write number of times are less than using machine number of times or read-write number of times, so obviously this time printer target data information that imaging box chip is sent for illegal.Otherwise, if in fact the machine number of times or the read-write number of times be not less than can use the machine number of times or the read-write number of times, explain that then the target data information that printer sends imaging box chip is legal.
Step 404: refusal writes said target data information.
Step 405: carry out data rewriting operation to said imaging box chip according to target data information.
In the present embodiment; Through judging whether imaging device is illegal to the target data information of sequence number in the imaging box chip or check bit; And when this target data information is illegal; The refusal imaging device is rewritten sequence number in the imaging box chip or check bit, thereby can be in the process of printer and chip communication is made data (for example sequence number or check bit etc.) that printer receives the chip transmission when deviation is arranged owing to disturbing, and also can keep the operate as normal of imaging device and imaging box chip; Imaging device writes the problem of data to the imaging box chip mistake in the prior art thereby solved, and then can practice thrift product resource.
