Description

Technical Field

[0001] The invention relates to the technical field of toner cartridge chip data processing, in particular to a toner cartridge chip identification system. Background Art

[0002] The toner cartridge chip is a chip integrated on the toner cartridge, which is used to identify and manage the relevant information of the toner cartridge. The toner cartridge chip is usually used in office equipment such as printers and copiers. It is designed to monitor the usage of the toner cartridge, the number of printed pages, the status of the toner cartridge and other information, and communicate with the printer to achieve effective cooperation and management between the printer and the toner cartridge.

[0003] Traditional toner cartridge chips monitor the remaining toner in the toner cartridge, usually issuing a warning when the toner inside the toner cartridge is close to being exhausted. If there is a specific printing requirement, such as requiring a printing device to print a large number of documents, the operator can only infer whether the remaining toner can meet the printing needs of a large number of documents by checking the remaining toner status of the toner cartridge identified by the toner cartridge chip in advance. This method is difficult to determine whether the remaining toner in the toner cartridge can meet the printing needs, which may cause the printing of a large number of documents to be interrupted, and the toner cartridge chip cannot effectively adjust and manage the printing settings according to the remaining toner in the toner cartridge and the printing volume.

[0004] To this end, the present invention provides a toner cartridge chip identification system. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a toner cartridge chip identification system, so that the toner cartridge chip can be used to identify the printing volume of the printing device and the remaining toner in the toner cartridge, and effectively adjust, remind and manage the remaining toner and printing volume to avoid the interruption of printing tasks.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a toner cartridge chip identification system, comprising:

[0007] A toner remaining amount identification module, wherein the toner remaining amount identification module includes a user inputting a pre-printing amount to a printing device, and after the toner cartridge chip receives the pre-printing amount, the toner cartridge chip obtains the remaining amount of toner in the toner cartridge before the printing job is performed, and after the printing job is started, when the number of pages currently printed reaches the identified page amount, the real-time toner remaining amount in the toner cartridge at this time is obtained, and the remaining amount of toner Fn in the toner cartridge before the printing job is subtracted from the real-time toner remaining amount Fs to obtain a primary toner consumption amount Hf=Fn-Fs, and then the primary toner consumption amount Hf is combined with the identified page amount Yn to obtain an estimated toner consumption per page , and the theoretical toner consumption Lh=Yh·Dn is obtained by the estimated toner consumption per page Yh and the pre-printing amount Dn input by the user to the printing device. If the theoretical toner consumption is less than or equal to the remaining amount of toner in the toner cartridge before the printing job, the estimated remaining amount of toner in the toner cartridge is sufficient to print all the pages of this printing volume; if the theoretical toner consumption is greater than the remaining amount of toner in the toner cartridge before the printing job, the estimated remaining amount of toner in the toner cartridge is not sufficient to print all the pages of this printing volume;

[0008] A light printing recognition module, wherein the light printing recognition module includes comparing the estimated printing volume with the printing volume qualification threshold when recognizing that the remaining toner in the toner cartridge cannot support printing all pages, and judging whether the light printing strategy can be implemented according to the comparison result; the specific method of obtaining the estimated printing volume is: when the system recognizes that the remaining toner in the toner cartridge cannot support printing all pages, the remaining amount of toner Fn in the toner cartridge before the printing job is divided by the estimated toner consumption per page Yh to obtain the estimated printing volume , and round the result; the specific judgment method of whether the light printing strategy can be implemented is as follows: if the estimated printing volume is greater than or equal to the qualified printing volume threshold, the system will execute the next light printing strategy; if the estimated printing volume is less than the qualified printing volume threshold, the system will directly feedback that the toner cartridge chip recognizes that the remaining toner in the toner cartridge is insufficient to support printing all pages, and prompt the operator to prepare to add toner in advance while continuing to execute the printing job normally;

[0009] A light printing estimation module, wherein the light printing estimation module includes an acceptable light printing threshold value set by a user, and a light printing strategy is used to judge the light printing degree required for the remaining toner in the cartridge to print all pages of the pre-printed amount; the light printing strategy includes, after the user selects a specific light printing threshold value, calculating the difference between the pre-printed amount input by the user to the printing device and the identified page amount to obtain the remaining print amount, dividing the real-time toner remaining amount Fs by the remaining print amount Sn to obtain the remaining consumable toner amount per page of printing paper Then, the light printing degree is obtained by combining the consumable powder amount Kx of each page of printing paper with the estimated powder consumption Yh of each page. ;

[0010] A result feedback module includes comparing the light printing threshold with the light printing degree. If the light printing degree is greater than or equal to the light printing threshold, the system will perform light printing; if the light printing degree is less than the light printing threshold, the system will prompt the operator to prepare to add toner in advance while continuing to execute the printing job normally. The toner cartridge chip will feed back the corresponding measures to the printing device by identifying the comparison results.

[0011] In some embodiments, the light printing estimation module also includes an acceptable light printing threshold set by the user, and the user can freely choose whether to use light printing when the toner cartridge is low on toner. If the user does not accept the color of the printed document becoming lighter, the system will directly feedback that the toner cartridge chip has identified that the amount of remaining toner in the toner cartridge is insufficient to support printing of all pages, and while continuing to execute the print job normally, the operator will be prompted to prepare to add toner in advance; if the user is willing to choose to use light printing, a specific light printing threshold is selected within the set range.

[0012] In some embodiments, a retention value k is set, and the retention value k is used to sum with the specific fade threshold value set by the user to obtain a stable fade threshold value;

[0013] When the degree of light printing is greater than or equal to the light printing threshold but less than the stable light printing threshold, the system will perform the light printing operation, but at the same time it will display it on the display screen of the printing device or send a signal to the control device to feedback that there is a risk of the toner cartridge being short of toner while the printing device is performing light printing.

[0014] The present invention further provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and the computer program is executed by a processor to implement the above-mentioned toner cartridge chip identification system.

[0021] Figure 2 The present invention is a schematic diagram of the principle of a toner cartridge chip identification system. DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0024] See also Figure 1 and Figure 2 The present invention provides a toner chip identification system, which includes: a toner remaining amount identification module, a light printing identification module, a light printing estimation module and a result feedback module.

[0025] The toner remaining amount recognition module includes a user inputting a pre-printing amount to the printing device, after the toner cartridge chip receives and records the pre-printing amount information input by the user, monitoring the remaining amount of toner in the toner cartridge and updating the toner remaining amount data in real time, then the printing device starts to print, after the printed pages reach the preset recognition page amount, the toner cartridge chip recognizes the change in the remaining amount of toner in the toner cartridge, and estimates whether the remaining amount of toner is sufficient to print a specified number of pages, the specific estimation method is as follows:

[0026] The toner chip obtains the remaining amount of toner in the toner before the print job. After the print job starts, when the number of pages currently printed reaches the identified page quantity, the real-time remaining amount of toner in the toner is obtained. The remaining amount of toner in the toner before the print job Fn is subtracted from the real-time remaining amount of toner Fs to obtain the primary toner consumption Hf=Fn-Fs. The primary toner consumption Hf is then combined with the identified page quantity Yn to obtain the estimated toner consumption per page. , and obtain the theoretical powder consumption Lh=Yh·Dn through the estimated powder consumption per page Yh and the pre-printing amount Dn input by the user to the printing device. By comparing the theoretical powder consumption Lh with the remaining amount Fn of toner in the toner cartridge before the printing job, it is estimated whether the remaining amount of toner in the toner cartridge is sufficient to print a specified number of pages. Specifically, if the theoretical powder consumption is less than or equal to the remaining amount of toner in the toner cartridge before the printing job, then the estimated remaining amount of toner in the toner cartridge is sufficient to print all the pages of this printing volume; if the theoretical powder consumption is greater than the remaining amount of toner in the toner cartridge before the printing job, then the estimated remaining amount of toner in the toner cartridge is not sufficient to print all the pages of this printing volume.

[0027] For example, the user is set to input a pre-printed amount of 200 pages to the printing device, and the identified page amount is 1 / 10 of the pre-printed amount, that is, 20 pages. Before the printing device starts printing, the toner cartridge chip identifies that the remaining toner in the toner cartridge is 8g. When the number of pages printed by the printing device reaches 20 pages, the toner cartridge chip now identifies that the real-time toner remaining in the toner cartridge is 7g, so that the primary powder consumption can be obtained as 1g, and the estimated powder consumption per page is 0.05g. Combined with the pre-printed amount of 200 pages, the theoretical powder consumption can be obtained as 10g. Because the toner cartridge chip identifies that the remaining toner in the toner cartridge is 8g before the printing device starts printing, which is less than the estimated theoretical powder consumption of 10g, the system can estimate that the remaining toner in the toner cartridge is insufficient to support printing all pages.

[0028] The light printing recognition module includes setting a qualified printing volume threshold. When the system recognizes that the remaining toner in the toner cartridge cannot support printing all pages, the remaining toner Fn in the toner cartridge before the print job is divided by the estimated toner consumption per page Yh to obtain the estimated printing volume. , and round the result, then compare the estimated print volume with the print volume qualified threshold, and judge whether the light printing strategy can be implemented according to the comparison result: if the estimated print volume is greater than or equal to the print volume qualified threshold, the system will execute the next light printing strategy; if the estimated print volume is less than the print volume qualified threshold, the system will directly feedback that the toner cartridge chip recognizes that the remaining toner in the toner cartridge is insufficient to support printing all pages, and prompt the operator to prepare to add toner in advance while continuing to execute the print job normally. At the same time, the setting of the print volume qualified threshold needs to be determined according to the specific number of pages of the pre-print volume input by the user to the printing device. For example, the user inputs a pre-print volume of 200 pages to the printing device, and the print volume qualified threshold can be taken as 2 / 3 of 200 pages, and the rounded result is 133 pages. Combined with the above embodiment, the estimated print volume is 160 pages obtained by dividing the remaining toner in the toner cartridge 8g identified by the toner cartridge chip before starting printing by the estimated toner consumption per page 0.05g. Since the estimated print volume of 160 pages is greater than the print volume qualified threshold of 133 pages, the system executes the next light printing strategy.

[0029] The light printing estimation module includes an acceptable light printing threshold set by the user, and uses a light printing strategy to judge the light printing degree required for the remaining toner in the toner cartridge to print all the pages of the pre-printed quantity. The user can freely choose whether to use light printing when the toner in the toner cartridge is low. If the user requires the best print quality for the document printed, and cannot accept the color of the printed document to be lighter, the system will directly feedback that the toner cartridge chip recognizes that the remaining toner in the toner cartridge is insufficient to support printing of all pages, and prompt the operator to prepare to add toner in advance while continuing to execute the print job normally. If the user is willing to choose to use light printing, he can select a specific light printing threshold within the set range.

[0030] The light printing strategy includes: after the user selects a specific light printing threshold, the remaining printing amount is obtained by calculating the difference between the pre-printed amount input by the user to the printing device and the recognized page amount, and the real-time toner remaining amount Fs is divided by the remaining printing amount Sn to obtain the remaining consumable toner per page of printing paper. Then, the light printing degree is obtained by combining the consumable powder amount Kx of each page of printing paper with the estimated powder consumption Yh of each page. , and convert the calculation result into a percentage value. In combination with the above-mentioned embodiment, the real-time remaining toner is set to 7g. Since the pre-printed amount input by the user to the printing device is 200 pages, and the identified page amount is 20 pages, that is, the remaining printing amount is 180 pages, it can be concluded that the consumable toner for each remaining page of printing paper is 0.39g. Then, the consumable toner for each page of 0.39g is divided by the estimated toner consumption per page of 0.05g to obtain a light printing degree of 78%. This means that when each remaining page of printing paper is subsequently printed, compared with the toner output of the normal toner cartridge, at most 78% of the actual toner output can be used, and the content on the printing paper will also fade with the reduction of toner output, but it can still meet most reading and use needs.

[0031] As for the specific method of controlling the amount of toner output from the toner drum, in the existing printing device, the surface of the toner drum is charge-regulated through a charge control system to ensure that the carbon powder can be properly adsorbed onto the surface of the toner drum, thereby forming clear printed content. This charge control system plays a key role in the printing process and can accurately control the charge distribution on the toner drum to achieve print output. When the system needs to perform light printing, the charge control system in the printing device can be used to adjust the charge distribution on the toner drum, thereby affecting the amount of toner output from the toner drum. This technology already exists and has been widely used. It is also a common method in existing printing technology. The purpose of lightening the printed content can be achieved by adjusting the charge distribution. And the use of this method of controlling the amount of toner output from the toner drum has the following advantages:

[0032] Precise adjustment: The charge distribution on the toner cartridge is precisely adjusted through the charge control system to achieve precise control of the toner output of the toner cartridge, ensuring the accuracy and consistency of the faded printing effect;

[0033] Flexibility: By adjusting the charge control system, the system can flexibly control the toner output of the toner cartridge as needed, achieve different degrees of faded printing, and meet users' diverse needs for printing effects;

[0034] Efficiency: The system uses charge control to control the toner output of the toner cartridge quickly and efficiently, and can make real-time adjustments during the printing process to ensure smooth and efficient completion of the printing job.

[0035] At the same time, the light printing threshold can be set in the range of 70% to 90%, and the light printing threshold selected by the user is set to 75%. The result feedback module includes comparing the light printing threshold with the light printing degree. If the light printing degree is greater than or equal to the light printing threshold, it means that even if the toner cartridge chip recognizes that the remaining amount of toner in the toner cartridge is not enough for subsequent printing and needs to be printed with faded content, the degree of fading is still within the user's acceptable range. The system will perform faded printing to complete all printing tasks without pausing the printing job; if the light printing degree is less than the light printing threshold, it means that the toner cartridge chip recognizes that the remaining amount of toner in the toner cartridge is not enough for subsequent printing, and even if the content is printed with a faded quality acceptable to the user, it still cannot meet the pre-printed page number requirement. The system will feedback that the toner cartridge chip recognizes that the remaining amount of toner in the toner cartridge is insufficient to support printing all pages, and prompt the operator to prepare to add toner in advance while continuing to perform the printing job normally.

[0036] According to the above preferred embodiment, the light printing degree is set to 78%, and the light printing threshold selected by the user is set to 75%. Since the light printing degree is greater than the light printing threshold, the system will reduce the toner output of the subsequent printed pages so that the actual toner output is equal to 75% of the light printing threshold, thereby achieving light printing. By reducing the actual toner output to 75% of the light printing threshold, the system achieves light processing of subsequent printed pages, thereby ensuring the continuity of the print job. Even if the toner in the toner is insufficient, the system can still complete all printing tasks without suspending the print job. In addition, by reducing the toner output of the toner, the system can effectively extend the service life of the toner, save toner resources while ensuring the continuous output of printing, thereby reducing the frequency and cost of adding toner and replacing the toner, thereby reducing the frequency and cost of adding toner and replacing the toner.

[0037] In addition, in another embodiment, the system may set a retention value k, and the retention value k is used to sum with the specific light printing threshold after the user sets it, to obtain a stable fade threshold. For example, the retention value is set to 5%. When the user sets the specific light printing threshold to 75%, it can be concluded that the stable fade threshold is 80%, and the stable fade threshold is used to compare the light printing degree. If the light printing degree is greater than or equal to the stable light printing threshold, the system performs fade printing normally. If the light printing degree is less than the stable light printing threshold, when the system prints with 75% of the actual powder output, it will feedback that there is a risk of insufficient toner in the toner cartridge, and the operator is prompted to prepare to add toner in advance. This is because although the system has estimated whether the remaining toner is sufficient to print a specified number of pages, in actual printing jobs, even for the same batch of print jobs, it is difficult to ensure that the specific content of each page (content density, color depth, etc.) remains completely consistent. The stable fade threshold is set to increase the requirements for the remaining toner for printing the remaining pages. Therefore, when the light printing degree is greater than or equal to the light printing threshold but less than the stable fade threshold, the system will perform the fade printing operation, but will simultaneously display the display on the printing device or send a signal to the control device to feedback that there is a risk of insufficient toner in the toner cartridge while the printing device is performing fade printing. When the light printing degree is greater than or equal to the light printing threshold but less than the stable fade threshold, the system can identify the risk of insufficient toner in the toner cartridge and notify the operator through the display or signal to prepare to add toner in advance, reducing the risk of printing interruption caused by insufficient toner in the toner cartridge and ensuring the smooth progress of the printing job.

[0038] In summary, the present invention aims to design a toner cartridge chip identification system, which uses the toner cartridge chip to receive the printing volume of the printing device and the real-time identified changes in the amount of toner in the toner cartridge, and solves the problem of insufficient toner in the toner cartridge based on the information identified by the chip. Specifically, it estimates whether the remaining toner is sufficient to print a specified number of pages, and when it is estimated that the remaining toner in the toner cartridge is not sufficient to print all the pages of this printing volume, the system will reduce the toner output of the subsequent toner cartridges, so that the content on the printed page fades, thereby ensuring that the remaining toner in the toner cartridge can complete all printing tasks, thereby achieving the purpose of managing printing jobs, avoiding printing interruptions and frequent toner cartridge replacements caused by insufficient toner, and improving work efficiency; users can flexibly adjust whether to perform faded printing, and the degree of faded printing can also be freely set, thereby improving the flexibility and intelligence of printing jobs. The system can also monitor the remaining amount of toner in the toner cartridge in real time, and make judgments based on preset thresholds and the degree of light printing, promptly reminding users whether the toner in the toner cartridge is sufficient to support printing of all pages, ensuring that users can understand the usage of the toner cartridge at any time during the printing process. Through the effective reminder function, users can manage the usage of the toner cartridge more conveniently, improving user experience and printing efficiency.
