And the matching of A and B means that the similarity of A and B is greater than or equal to a preset threshold value.
As used herein, "if" may be interpreted as "at … …" or "when … …" or "in response to a determination" or "in response to a detection", depending on the context.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Referring to fig. 1, a schematic diagram of a printing system according to an embodiment of the present invention is shown. The consumable 12 shown in fig. 1 is, for example, an ink cartridge having a consumable chip 121, and the printer main body 11 consumes ink contained in the ink cartridge to perform a printing operation. After each printing operation is finished, the printer body 11 determines consumption data of the printing material in the printing operation according to the control information of the printing ink jet amount, and sends printing operation feedback information to the consumable chip 121, where the printing operation feedback information at least includes the consumption data corresponding to the printing operation. The consumable chip 121 calculates and updates a consumable remaining amount, for example, an ink remaining amount after a printing operation, when the printer main body 11 writes information.
Currently, the conventional method for calculating the remaining amount of consumable supplies is to subtract the consumption data sent by the printer from the current remaining amount and then subtract the amount of the consumed material, wherein the amount of the consumed material is usually matched with the consumable supplies of the original factory. The quality of genuine consumables is usually better or more suitable than the quality of compatible consumables of non-genuine factories, and the printing material utilization rate that genuine consumables held will also be higher. When the printer uses the original factory consumables to print, the waste powder/waste ink amount generated by the original factory consumables is a standard value; however, when the printer prints using compatible consumables of the same capacity but different factories, the compatible consumables generate more waste powder/waste ink. However, at present, most consumable chips compatible with consumables calculate the remaining amount of the accommodated printing material according to the waste powder/waste ink data of the consumable supplies of the original factory. Thus resulting in erroneous determination of the balance of compatible consumables. It may happen that the printing material in the compatible consumable is completely consumed, but the data related to the printing material remaining amount in the consumable chip still indicates that the printing material is remaining, thereby causing printing failure or unreliability.
Referring to fig. 2, which is a flowchart illustrating a method for determining a remaining amount of a consumable part according to an embodiment of the present invention, an execution subject of the method shown in fig. 2 may be a consumable remaining amount determining apparatus, which may be a software and/or hardware apparatus, for example, a consumable chip or a processor in the consumable chip, and the software apparatus may be a software module in the consumable chip. The method shown in fig. 2 includes steps S101 to S104, which are specifically as follows:
and S101, acquiring the stored consumable remaining amount, and consumption data and the number of printed pages corresponding to the printing operation.
It can be understood that the consumable chip stores the consumable allowance, when the first printing operation is performed, the printing material in the consumable is not used, the consumable allowance is the consumable capacity, and along with the increase of the number of times of the printing operation, the consumable allowance is continuously replaced, updated and reduced. The consumable balance can be a value of 0-100, or a percentage value of 0% -100%, and is not limited herein. The present step may be that the consumable supply remaining amount determining means acquires a pre-stored consumable supply remaining amount before the printing operation is performed.
In some embodiments, the print operation is, for example, an operation performed on a single user print job, and the number of print pages corresponding to one print operation is determined according to the number of pages of the print job. After finishing one-time printing operation, the printer main body detects the consumption data and the printing page number and sends the printing operation feedback information carrying the consumption data and the printing page number to the consumable chip. The consumable remaining amount determining device acquires consumption data and the number of printed pages corresponding to the printing operation from the printing operation feedback information sent by the printer main body.
And S102, determining a target coverage rate range according to the consumption data and the number of printed pages.
The coverage is an area ratio of a print pattern for printing one page in the whole page when the printer main body performs a printing operation. And the target coverage range is a preset range in which the coverage corresponding to the printing operation falls. Assume that at least 3 coverage ranges are set: low coverage range (e.g., coverage of 0% to 5%), medium coverage range (e.g., coverage of 6% to 20%), and high coverage range (e.g., coverage of 21% to 100%). In the preset information, each coverage rate range corresponds to a consumption range and a waste grading value of each page. In one embodiment, the preset correspondence relationship among the consumption range, the coverage range, and the waste classification value of each page may be, for example, the following proportional relationship example:
the consumption range of each page is preset to be 0-0.05, the consumption range corresponds to a low coverage rate range (for example, the coverage rate is 0% -5%), and the grading value of each page of corresponding waste is preset to be 0.02;
the consumption range of each page is preset to be 0.05-0.2, the corresponding coverage rate range (for example, the coverage rate is 5% -20%) is provided, and the grading value of each page of corresponding waste is preset to be 0.005;
the consumption range of each page is preset to be 0.2-1, the consumption range corresponds to a high coverage rate range (for example, the coverage rate is 20% -100%), and the grading value of each page of waste corresponding to the consumption range is preset to be 0.001.
The consumption per page range is a consumption amount range in which consumption data of one printing operation is divided into each page on average. The preset coverage rate ranges comprise a first coverage rate range corresponding to a first range consumed by each page, wherein the maximum value in the first range consumed by each page is the quotient of the rated consumable material capacity and the rated printed page number. For example, the consumption range of each page is 0-0.05, which is a preset first-class consumption range of each page, and can be calculated according to the rated consumable capacity 100 of the consumable chip of the original factory and a preset rated number of printed pages of 2000 pages: 100 ÷ 2000 ÷ 0.05. The preset rated printed page number refers to the maximum printable page number of the consumable material of the original factory. It should be understood that each page of the consumption first-class range is a first-class value preset according to the original plant consumables, and the corresponding coverage rate range and each page of the waste grading value are the first-class range and the value corresponding to the original plant consumables. For compatible consumables of non-original plants, the average consumption of each page may exceed the first-class consumption range of each page and fall into other preset ranges, so that corresponding grading values of each page of waste can be inquired and obtained, and the waste amount is calculated.
It should be understood that the preset correspondence relationship among the consumption range, the coverage range and the scrap grade value of each page has the characteristics of equal proportion change and inverse proportion change, and is only used as an optional correspondence relationship. In practical application, the coverage rate range can be arbitrarily divided according to actual requirements, and the consumption range and waste grading value of each page corresponding to each coverage rate range are set, and the setting can be non-equal proportion change and non-inverse proportion change, which is not limited herein. The first consumption range per page is a first value preset according to consumable materials of the original factory, but may also be a preset standard value, for example, a lower consumption range per page specified by the industry, and the embodiment is not limited thereto. Similarly, the first coverage range and the classification value of each page of waste corresponding to the first coverage range are not limited to be set according to the original plant consumable material characteristics.
The above embodiment only takes 3 coverage ranges as an example, but actually, the coverage ranges may be divided into more subdivided coverage ranges of 2, 4, 5 or more, and are not limited herein.
In step S102 (determining the target coverage range according to the consumption data and the number of printed pages), an average consumption per page may be determined according to the consumption data and the number of printed pages. The average consumption per page is obtained by dividing the consumption data by the number of printed pages. And then, determining a target coverage rate range in a plurality of preset coverage rate ranges according to the average consumption per page, wherein the average consumption per page is included in the consumption per page range corresponding to the target coverage rate range. For example, if 100 pages are printed using the consumable material for the first time, 1% of the printing material is consumed, and the consumption data is 1. To calculate the remaining amount of consumables in this printing operation, the average consumption per page is first calculated: consumption data 1 of this printing divided by 100 pages printed in this printing operation is an average consumption per page of 0.01. The consumption range of 0.01 included in each page is preset to 0-0.05, which corresponds to the low coverage range (coverage of 0% -5%) and the classification value of the waste material of each page is preset to 0.02 according to the corresponding relationship in the above embodiments. The corresponding relationship may be realized by means of table lookup and the like, and is not limited herein.
In some implementations of the aforementioned embodiments, the preset plurality of coverage ranges further includes at least one coverage range of the second type. And the ratio of the maximum value in each second coverage rate range to the maximum value in the first coverage rate range is consistent with the ratio of the maximum value of each page consumption range corresponding to the second coverage rate range to the maximum value of each page consumption first coverage rate range. Assuming that the first-class consumption range of each page is preset to be 0-0.05, the first-class coverage range is 0% -5%, and the grading value of each page of waste corresponding to the first-class coverage range is 0.02. Then, for the consumption range of each page preset to be 0.05-0.2, the medium coverage range (such as the coverage rate is 5% -20%), and the classification value of each page waste preset to be 0.005, 20%: and 5% ═ 0.2: 0.05. for another example, the consumption range per page is preset to be 0.2-1, the coverage rate range is high (for example, the coverage rate is 20% -100%), and the classification value per page of waste is preset to be 0.001, 100%: and 5% ═ 1: 0.05.
in some implementations of the aforementioned embodiments, the plurality of coverage ranges also includes at least one coverage range of a second type. And the ratio of the maximum value in each second-class coverage rate range to the maximum value in the first-class coverage rate range is the reciprocal of the ratio of each waste grading value corresponding to the second-class coverage rate range to each waste grading value corresponding to the first-class coverage rate range. Continuously assuming that the first-class consumption range of each page is preset to be 0-0.05, the first-class coverage range is 0% -5%, and the grading value of each page of waste corresponding to the first-class coverage range is 0.02. Then, for the consumption range of each page preset to be 0.05-0.2, the medium coverage range (such as the coverage rate is 5% -20%), and the classification value of each page waste preset to be 0.005, 20%: 5% is 0.005: reciprocal of 0.02. For another example, the consumption range per page is preset to be 0.2-1, the coverage rate range is high (for example, the coverage rate is 20% -100%), and the classification value per page of waste is preset to be 0.001, 100%: 5% is 0.001: reciprocal of 0.02.
In an actual printing operation, for single-page printing, there is obviously a rule that: when the coverage rate is low, the higher the grading value of each page of waste material which represents the waste material amount is; conversely, when the coverage rate is high, the lower the grade value of each page of waste material representing the amount of waste material.
S103, determining the waste amount corresponding to the printing operation according to the printing page number and the waste grading value of each page corresponding to the target coverage rate range.
After the target coverage range is determined, for the same number of printed pages, according to the preset corresponding relation, the larger the maximum value of the target coverage range is, the smaller the waste amount is, and the smaller the maximum value of the target coverage range is, the larger the waste amount is. The amount of waste can be obtained in combination with the number of printed pages and the target coverage range.
In some embodiments, the amount of waste corresponding to the printing operation may be determined according to the waste classification value of each page corresponding to the number of printed pages and the target coverage range. For example, in the embodiment where the average consumption per page calculated as above is 0.01, 0.01 is included in the consumption per page range preset to 0 to 0.05, which corresponds to a low coverage range (coverage of 0% to 5%) and a classification value of waste per page is preset to 0.02. Thus, the amount of waste for printing 100 pages, i.e., the waste classification value 0.02 × the number of printed pages 100 pages per page, is calculated again as the amount of waste 2 corresponding to the printing operation.
And S104, determining the current consumable material allowance after the printing operation is executed according to the pre-stored consumable material allowance, the consumption data and the waste material amount.
Specifically, the difference value obtained by subtracting the sum of the consumption data and the amount of waste from the pre-stored consumable remaining amount may be used as the current consumable remaining amount after the printing operation is performed. For example, in the embodiment where the consumption data is 1 and the amount of waste corresponding to the printing operation is 2, if printing is performed for the first time, the pre-stored remaining amount of the consumable material is 100, and the current remaining amount of the consumable material after the printing operation is 100-1-97. Store 97 as consumable balance, cover original 100. For another example, if 10 pages are printed again using the consumable material, and 3% of the printing material is consumed, the consumption data is 3. The average consumption per page is calculated, and the consumption data of the printing operation of this time is 3 ÷ 10 pages printed, which is 0.3. Then find the consumption range per page to which 0.3 belongs. Referring to the correspondence relationship of the above examples, the classification value of each page of waste corresponding to high coverage (20% to 100%) is 0.001. Then, the amount of waste for printing 10 pages is calculated, that is, the classification value of waste per page is preset to 0.001 × number of printed pages 10 — the amount of waste 0.01. The current remaining amount of consumable after the printing operation is the pre-stored remaining amount of consumable 97-consumption data 3-waste amount 0.01 is 93.99.
Then, the pre-stored consumable amount may be updated with the current consumable remaining amount after the printing operation is performed. A specific update is, for example, data overwriting storage, replacing old values with new values. For example, 97 is stored as a consumable supply allowance, and the original 100 is overwritten. 93.99 is stored as consumable allowance to cover the original 97.
In the method for determining the remaining amount of consumable items provided by this embodiment, a pre-stored remaining amount of consumable items, consumption data corresponding to a printing operation, and a number of printed pages are obtained; determining a target coverage rate range according to the consumption data and the number of printed pages; determining the waste amount corresponding to the printing operation according to the printing page number and the waste grading value of each page corresponding to the target coverage rate range; and determining the current consumable balance after the printing operation is executed according to the pre-stored consumable balance, the consumption data and the waste amount, introducing correlation calculation with the original factory consumable data in the determination of the waste amount, and improving the accuracy of determining the waste amount and further improving the accuracy and reliability of updating the consumable balance.
In other embodiments, the printing operation may also be a virtual printing operation (also referred to as a calibration operation), for example. The method further comprises the following steps: receiving virtual printing operation feedback information excluding the number of printed pages from the printer main body; acquiring consumption data of virtual printing according to the virtual printing operation feedback information; and taking the difference obtained by subtracting the consumption data of the virtual printing from the pre-stored consumable material allowance as the current consumable material allowance after the virtual printing operation is executed. The virtual printing operation is to calibrate the custom color, consumption data and other data stored in the consumable chip, so that the printer main body can provide better printing quality. The printer body automatically triggers execution of a dummy print operation when it detects that a new consumable (having a new consumable chip) is installed in the printing apparatus, or when it detects that the printer is powered on, or when a threshold value for accumulating the number of printed pages (for example, 500 pages are printed cumulatively) is printed using the consumable. The printer main body performs a dummy printing operation, which consumes a printing material as in the real printing operation, except that a transfer medium (e.g., printing paper) is not used in the dummy printing operation, and thus the consumed printing material is entirely used as waste. Also, the consumption data or the amount of waste per virtual printing operation is the same fixed value (e.g., 0.05). In order to avoid repeatedly subtracting the consumption data (0.05) and the waste amount (0.05), the accuracy of the consumable supply allowance of the virtual printing operation is improved, and the current consumable supply allowance after the printing operation of the virtual printing operation is equal to the pre-stored consumable supply allowance 93.99-the consumption data 0.05 is equal to 93.94. Then, the current remaining consumable amount 93.94 after the virtual printing operation is stored as a remaining consumable amount, which covers the original 93.99.
Referring to fig. 3, which is a schematic structural diagram of a consumable quantity determining apparatus according to an embodiment of the present invention, the consumable quantity determining apparatus 30 shown in fig. 3 can be understood as a software program in a consumable chip for executing the method steps shown in fig. 2.
