Description

Technical Field

[0001] The present application relates to the technical field of image forming devices, and in particular to a fixing control method, an image forming device and a storage medium. Background Art

[0002] Laser printers are a common image forming device that needs to go through multiple steps such as charging, exposure, development, transfer, fixing, and cleaning when printing. Among them, the fixing step is to heat and melt the toner on the paper through a heating roller, so that the resin in the toner is fixed on the paper and is not easy to fall off. The fixing temperature, that is, the temperature of the heating roller, will affect the final fixing effect. When the fixing temperature is too low, the toner is not completely melted and fixed on the paper, resulting in poor fixing. When the fixing temperature is too high, the paper will curl due to heat, resulting in paper jams. At present, image forming devices use a fixed fixing temperature to fix printed images of the same paper size. This method may cause poor fixing effects in areas with high printing rates in the printed image, and increase the energy consumption of fixing in areas with low printing rates. Summary of the invention

[0059] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0060] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0061] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0062] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0063] In order to solve the defects in the prior art of using a fixed fixing temperature for the same type of paper, which results in the inability to ensure the image quality effect in areas with a higher printing rate and the high fixing energy consumption in areas with a lower printing rate, the present invention provides a fixing control method that can perform fine fixing control on different areas of an image according to the printing rate. Figure 1 Flow chart of a fixing control method provided by an embodiment of the present invention. Figure 1 As shown in , the method includes:

[0064] Step 101, determining the page coverage of the printed image and the reference fixing temperature.

[0065] The page coverage refers to the ratio of the coverage area of ​​ink / toner on the paper to the total area of ​​the paper. The image forming device receives the print task sent by the print driver, and analyzes the print image corresponding to the print task through the data firmware to obtain the page coverage of the print image.

[0066] The reference fixing temperature can be determined based on the page coverage obtained above. Specifically, the image forming device first receives a print task issued by a user. Based on the print task, corresponding n print images are obtained, where n is a positive integer ≥ 1. Then, the n page coverages corresponding to the n print images are determined, and the n page coverages correspond one-to-one to the n print images. Then, the n reference fixing temperatures corresponding to the n page coverages are determined. The n reference fixing temperatures correspond one-to-one to the n page coverages. That is, each print image has a corresponding reference fixing temperature, and when the page coverages between the n print images are different, the reference fixing temperatures between the n print images are also different.

[0067] In some embodiments, it can also be implemented that multiple print images correspond to the same page coverage. Specifically, after receiving the print task, the image forming device obtains m print images based on the print task, where m is a positive integer ≥ 1. Then, the m page coverages corresponding to the m print images are determined. The m page coverages correspond one-to-one to the m print images. Finally, the common fixing temperature of the m print images is determined according to the m page coverages, and the common fixing temperature is used as the reference fixing temperature of the m print images. Optionally, the average value of the m page coverages can be calculated, and the reference fixing temperature corresponding to the value can be determined according to the average value of the page coverages as the common fixing temperature of the m print images. Alternatively, the median of the m page coverages is calculated, and the reference fixing temperature corresponding to the value can be determined according to the median of the page coverages as the common fixing temperature of the m print images. That is, the reference fixing temperatures of the m print images are the same.

[0068] A mapping relationship between different page coverages and different reference fixing temperatures (ie, the second mapping relationship described below) can be established in advance. Based on the mapping relationship and the page coverage of the printed image, the reference fixing temperature of the printed image can be obtained.

[0069] Table 1-1 shows part of the second mapping relationship between different page coverages and different reference fixing temperatures.

[0070] Page Coverage Reference fixing temperature (℃) (a-3)％ T1-15 (a-2)％ T1-10 (a-1)％ T1-5 a％ T1 (a+1)％ T1+5 (a+2)％ T1+10 (a+3)％ T1+15

[0071] Table 1-1

[0072] As shown in Table 1-1, as the page coverage increases, the corresponding reference fixing temperature also increases accordingly. For every 1% increase in the page coverage, the reference fixing temperature increases by 5°C. The mapping relationship between the page coverage and the reference fixing temperature is not limited to Table 1-1, and can be set according to different user needs and the performance adaptability of the image forming device.

[0073] Step 102, dividing the print image into a plurality of page areas according to the content of the print image.

[0074] The data firmware of the image forming device divides the print image along the paper feeding direction, and divides the print image into a plurality of page areas.

[0075] In a specific example, the data firmware of the image forming device analyzes the issued print task to perform area division. The image forming device can divide the print image into a header area, a footer area, and a text area according to the print parameters of the print task corresponding to the print image. The data firmware can obtain the positions of the header part and the footer part by analyzing the print parameters of the print task, and then determine the corresponding header area from the print image according to the position of the header part. And determine the corresponding footer area from the print image according to the position of the footer part. After that, the image forming device can determine the area other than the header area and the footer area in the print image as the text area. It should be noted that in some embodiments, the print image can include one or more combinations of the header area, the footer area, and the text area. That is, the print image can have only the text area, without the header area and the footer area. It can also have the header area and the text area, without the footer area. It can also have the footer area and the text area, without the header area. It can even have both the header area and the footer area and the text area.

[0076] The main text area can be further subdivided. Since the page coverage corresponding to the image content and the text content is quite different, the distribution information of the text and / or the image can be determined according to the printing parameters. Then, the main text area is divided into at least one sub-area according to the distribution information of the text and / or the image. The sub-area includes one or more combinations of the text area, the image area and the blank area. For example, by parsing the printing parameters, it is obtained that the printed image contains a picture, and then the main text area contains a picture area. The upper boundary of the picture area can be determined according to the upper edge of the picture. The lower boundary of the picture area can be determined according to the lower edge of the picture. For the blank part in the text area that has neither text nor picture, the part can be determined as the blank area in the text area. The part that only includes text is determined as the text area. The part that includes both pictures and text can also be determined as the picture area.

[0077] Figure 2A schematic diagram of page area division provided by an embodiment of the present invention. Figure 2 As shown in the figure, the printed image only has the main text part, without the header part and the footer part. Therefore, the main text part is divided. First, the part where the picture above the printed image is located is divided into the picture area (i.e. Figure 2 The text area (i.e. the area A shown in FIG. 1 ) is divided into the text area (i.e. the area A shown in FIG. 1 ). Figure 2 The blank area below is the blank area (i.e. Figure 2 The area shown in C).

[0078] Step 103: determining the actual printing rate corresponding to each page area.

[0079] The actual printing rate is determined by the actual coverage of the toner / ink that has been transferred to the paper. At this point, the print image has completed the transfer and is about to enter the fixing module for fixing. Before fixing, the actual printing rate of each page area is determined by detecting the actual coverage area of ​​the toner or ink on the paper.

[0080] Specifically, the image forming device can obtain the number of ink dots in each page area corresponding to each printed image and the actual area of ​​each ink dot. Then, the actual ink coverage area of ​​each page area is determined according to the number of ink dots in each page area and the actual area of ​​each ink dot. And, the theoretical ink coverage area of ​​each printed image is determined according to the total number of ink dots in each printed image and the unit ink dot area. Among them, the theoretical ink coverage area is different from the actual ink coverage area, which is the product of the total number of ink dots in the entire page printed image and the unit ink dot area. The unit ink dot area is the area occupied by a unit ink dot on the paper. Finally, according to the ratio of the actual ink coverage area of ​​each page area to the theoretical ink coverage area of ​​the printed image, the actual printing rate of each page area is determined. When the image forming device is fault-free, the sum of the actual ink coverage area of ​​each page area should be equal to the theoretical ink coverage area. The sum of the actual printing rates of each page area should be equal to 100%.

[0081] Step 104 , determining a temperature compensation value for each page area according to each actual printing rate corresponding to the plurality of page areas.

[0082] Before determining the temperature compensation value corresponding to each page area, a first mapping relationship between a reference printing rate and a reference temperature compensation value can be preset, and different reference printing rates are mapped to different reference temperature compensation values. Afterwards, the image forming device can obtain the first mapping relationship between the preset reference printing rate and the reference temperature compensation value when performing printing, and determine the temperature compensation values ​​corresponding to the actual printing rates based on the first mapping relationship and the actual printing rates. Among them, the reference printing rate corresponds to the page coverage rate one by one. Finally, the temperature compensation values ​​corresponding to the actual printing rates are used as the temperature compensation values ​​of the corresponding page areas. Table 1-2 is a first mapping relationship between a reference printing rate and a reference temperature compensation value provided in an embodiment of the present invention, which shows the mapping relationship between part of the reference printing rate and the reference temperature compensation value.

[0083] Reference printing rate Reference temperature compensation value (℃) (b-3)％ △T-6 (b-2)％ △T-4 (b-1)％ △T-2 b％ △T (b+1)％ △T+2 (b+2)％ △T+4 (b+3)％ △T+6

[0084] Table 1-2

[0085] As shown in Table 1-2, the reference temperature compensation value increases with the increase of the reference printing rate. If the reference printing rate changes by 1%, the reference temperature compensation value increases or decreases by 2°C. Of course, the mapping relationship between the reference temperature compensation value and the reference printing rate can be set according to user requirements or image forming device performance.

[0086] Step 105 , determining the actual fixing temperature of each page area according to the reference fixing temperature and the temperature compensation value of each page area.

[0087] Among them, based on the first mapping relationship between the reference printing rate and the reference temperature compensation value in step 104 and the one-to-one correspondence between the reference printing rate and the page coverage, and the second mapping relationship between the page coverage and the reference fixing temperature, the reference fixing temperature corresponding to each actual printing rate can be obtained. Then the algebraic sum between each temperature compensation value and the corresponding reference fixing temperature is determined. The algebraic sum between each temperature compensation value and the corresponding reference fixing temperature is determined as the actual fixing temperature of each page area. Specifically, the actual fixing temperature can be calculated by the formula T=A+B. Among them, T is the actual fixing temperature of the page area, A is the reference fixing temperature of the printed image, and B is the temperature compensation value of the page area. For different printed images with the same page coverage, due to different text distribution and different image distribution, the page areas after area division are not necessarily the same, the actual printing rates are not necessarily the same, and the final actual fixing temperatures are not necessarily the same.

[0088] In a specific scenario, the printing task includes multiple printing images. Each printing image corresponds to a separate reference fixing temperature. The actual fixing temperature of the page area is the algebraic sum of the temperature compensation value corresponding to the page area and the reference fixing temperature corresponding to the printing image where the page area is located. For example, the printing task includes three printing images, and the page coverage of the three printing images is a, b, and c. The reference fixing temperatures corresponding to a, b, and c are A1, A2, and A3, respectively. The reference fixing temperatures of the three printing images are A1, A2, and A3, respectively. For the page area in the first printing image, its actual fixing temperature is A1+B. For the page area in the second printing image, its actual fixing temperature is A2+B. For the page area in the third printing image, its actual fixing temperature is A3+B. Among them, B is the temperature compensation value corresponding to the page area, and the compensation value is determined according to the actual printing rate of the page area.

[0089] In another specific scenario, the printing task includes multiple printing images. All the printing images correspond to a common reference fixing temperature. Then the actual fixing temperature of the page area in each printing image is the algebraic sum of the temperature compensation value corresponding to the page area and the common reference fixing temperature. For example, the printing task includes three printing images, and the page coverage of the three printing images is a, b, and c. Calculate the average value of a, b, and c, recorded as d. Then determine the reference fixing temperature A corresponding to d. Then the reference fixing temperature of the three printing images is A. For the page area in the three printing images, the actual fixing temperature is A+B, where B is the temperature compensation value corresponding to the page area, and the compensation value is determined according to the actual printing rate of the page area.

[0090] Step 106 , performing a fixing process on the printed image according to the actual fixing temperature corresponding to each page area.

[0091] For example, fix the toner of a printed image in the A4 size. The data firmware analyzes that the page coverage rate is 40%. The printed image is divided into four page areas, namely area A, area B, area C, and area D according to the content of the printed image. The actual printing rate of area A is a, the actual printing rate of area B is b, the actual printing rate of area C is c, and the actual printing rate of area D is d. The image forming apparatus determines that the actual fixing temperature of area A is T1, the actual fixing temperature of area B is T2, the actual fixing temperature of area C is T3, and the actual fixing temperature of area D is T4 according to the actual printing rate. The actual printing rates from low to high are d < c < b < a. Then the actual fixing temperatures of the four page areas from low to high are: T4 < T3 < T2 < T1. The fixing device uses different fixing temperatures for page areas with different actual printing rates for fixing. The higher the actual printing rate, the higher the actual fixing temperature. The lower the actual printing rate, the lower the actual fixing temperature. Through the above fixing control method, the fixing temperature of the local area segment of the printed image is finely controlled, improving the quality of the printed image while reducing power consumption.

[0092] Figure 3 The figure is a schematic diagram of a fixing principle provided by an embodiment of the present invention. As Figure 3 shown in the figure, it includes a heating roller 301 located above, a halogen lamp 302 inside the heating roller 301, and a pressure roller 303 below. The paper 304 passes through between the heating roller 301 and the pressure roller 303 in the arrow direction. Taking Figure 2 the printed image shown in the figure as an example, the actual fixing temperatures corresponding to area A, area B, and area C are T1, T2, and T3 respectively. Area A, area B, and area C pass through the heating roller 301 in sequence. When the part of area A passes through the heating roller 301, control the halogen lamp 302 to heat the heating roller 301 to the temperature T1. Then, when the part of area B passes through the heating roller 301, control the halogen lamp 302 to heat the heating roller 301 to the temperature T2. Then, when the part of area C passes through the heating roller 301, control the halogen lamp 302 to heat the heating roller 301 to the temperature T3.

[0093] In some embodiments, for the same original document, since the sizes of the printing media selected by the user are different, the page areas after regional division thereof are not necessarily the same. At this time, the data firmware can divide the page areas according to the paper size. For continuous multi-page printing tasks, when there are cases where the page coverage rate is almost 0 or blank pages, the fixing device can be controlled to perform fixing at a lower fixing temperature or control the fixing device not to heat additionally, and use the remaining heat of the heating roller to fix the page.

[0094] In some embodiments, after the print image is divided into multiple page areas according to the content of the print image, adjacent page areas with similar actual printing rates can be merged to reduce the number of divided page areas, reduce the amount of data firmware calculation, reduce the variable temperature compensation control, and improve the control efficiency of the fixing device. Specifically, the difference in the actual printing rates of several adjacent page areas in the multiple page areas corresponding to each print image can be determined first. Several adjacent page areas whose difference is less than the first threshold are merged, and the sum of the actual printing rates of several adjacent page areas is used as the actual printing rate corresponding to the merged page area. Optionally, adjacent page areas with an actual printing rate difference of less than 0.5% can be combined. For example, the actual printing rates of two adjacent page areas are 19.4% and 19.6% respectively. The actual printing rate difference is 0.2%, which is less than the first threshold such as 0.5%, so the two adjacent page areas are merged to obtain a merged page area, and the actual printing rate of the merged page area is 19.4%+19.6%=39%.

[0095] It is also possible to identify whether the paper has a large dirty area by the actual printing rate. Specifically, the algebraic sum of the actual printing rates of all page areas corresponding to each printed image can be determined first. If the algebraic sum of the actual printing rates of all page areas of a printed image is greater than 100%, it can be determined that the paper is heavily dirty, and a prompt message indicating that the printed image is dirty can be issued. The dirt may be caused by leakage of toner in the ink cartridge or local damage on the surface of the photosensitive roller.

[0096] For example, a printing task includes two printing images. The first printing image is divided into four page areas. The second printing image is divided into three page areas. Among them, the actual printing rates of the four page areas of the first printing image are 10%, 30%, 50% and 10% respectively. Then the algebraic sum of the actual printing rates of the four page areas of the first printing image is 10% + 30% + 50% + 10% = 100%. There is no significant dirt on the first printing image. The actual printing rates of the three page areas of the second printing image are 30%, 40% and 35% respectively. Then the algebraic sum of the actual printing rates of the three page areas of the second printing image is 30% + 40% + 35% = 105%, which shows that the algebraic sum of the actual printing rates of the page areas of the second printing image is greater than 100%. Therefore, a prompt message is issued that the second printing image is dirty.
