Detailed Implementation Methods

[0042] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0044] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0045] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0046] One embodiment of the present invention provides a control method. Figure 1 A flowchart of a control method provided in an embodiment of the present invention is shown below. Figure 1 As shown, the method includes:

[0047] Step 102: Set the initial fixing temperature according to the paper type and printing conditions.

[0048] In one embodiment of the present invention, each step is performed by an image forming apparatus. The image forming apparatus includes, but is not limited to, printers, copiers, fax machines, scanners, and multifunction printers that integrate printing, copying, faxing, and scanning functions into one unit, the function of which is to print images or text on an imaging medium.

[0049] In one embodiment of the present invention, the paper type includes paper size and / or paper thickness. Printing conditions include the number of pages to be printed, printing colors, and / or single / double-sided printing conditions.

[0050] In one embodiment of the present invention, the direction perpendicular to the paper feed direction is the paper width, and the paper feed direction is the paper length. Different paper widths are distinguished, and the fixing temperatures corresponding to different paper widths are different. Different initial fixing temperatures T0 can be set according to different paper widths. The paper size can include large paper, medium paper, small paper, or a custom-sized paper type. For example, the paper type can be distinguished as large paper or small paper according to the paper width. Large paper has a paper width greater than or equal to 250 mm, and small paper has a paper width less than 250 mm.

[0051] For example, the initial fixing temperature T0 for large-format paper is shown in Table 1 below.

[0052] Table 1

[0053]

[0054] As shown in Table 1 above, paper thickness can include thin paper, plain paper 1, plain paper 2, or other paper types. Printing colors can include color printing or black and white printing. When the paper thickness of a large-format paper is thin, the printing color is color, the linear speed is N, the fixing pressure mode is normal, and the number of pages is 1 to 20 with single-sided printing, the initial fixing temperature T0 for this large-format paper can be set to t1. t1 to t36 in Table 1 can be set according to actual conditions.

[0055] Step 104: Obtain the ambient temperature compensation value and the printing temperature consumption to calculate the fixing temperature compensation value.

[0056] Figure 2 A flowchart for obtaining ambient temperature compensation values ​​is provided in one embodiment of the present invention, as follows: Figure 2 As shown, step 104 includes:

[0057] Step 1042a: Obtain the current ambient temperature based on the ambient temperature sensor.

[0058] In one embodiment of the present invention, the current ambient temperature can be obtained based on an ambient temperature sensor before each print job is issued.

[0059] Step 1044a: Determine the current fixing temperature state based on the current ambient temperature and the set temperature.

[0060] In one embodiment of the present invention, the fixing temperature state includes low temperature, normal temperature, or high temperature. For example, when the current ambient temperature is less than a first temperature threshold, the current fixing temperature state is low temperature; when the current ambient temperature is greater than or equal to the first temperature threshold and less than a second temperature threshold, the current fixing temperature state is normal temperature; when the current ambient temperature is greater than or equal to the second temperature threshold, the current fixing temperature state is high temperature.

[0061] Step 1046a: Determine the ambient temperature compensation value corresponding to the fixing temperature and paper thickness based on the fixing temperature and paper thickness.

[0062] In one embodiment of the present invention, the ambient temperature compensation values ​​corresponding to the fixing temperature state and paper thickness are shown in Table 2 below.

[0063] Table 2

[0064]

[0065] As shown in Table 2 above, T1 is the set first temperature threshold, T2 is the set second temperature threshold, T3 is the set third temperature threshold, and T_E is the current ambient temperature. For example, when ordinary paper 1 is at a high fixing temperature, the ambient temperature compensation value is -T3.

[0066] Figure 3 A flowchart for obtaining printing temperature consumption is provided in one embodiment of the present invention, as follows: Figure 3 As shown, step 104 includes:

[0067] Step 1042b: Determine the printer status.

[0068] In one embodiment of the present invention, the printer state includes a hot state and a cold state.

[0069] In one embodiment of the present invention, TF represents the temperature detected by the front-end thermistor, and TR represents the temperature detected by the rear-end thermistor (if there are only two thermistors on the heating assembly, the temperature detected by the thermistor located away from the center is taken as the temperature). If either TF or TR is greater than or equal to the set temperature (e.g., 100°C), the printer is determined to be in a hot-running state.

[0070] In one embodiment of the present invention, when the temperatures of both the TF and TR are lower than the set temperature (e.g., 100°C), the printer is determined to be in a cold state.

[0071] Step 1044b: When the printer is in a cold state, set the printing temperature consumption to the first set value.

[0072] For example, when the printer is in a cold state, the printing temperature consumption is set to 0.

[0073] Step 1044c: When the printer is in a warm-up state, obtain the current ambient temperature based on the ambient temperature sensor.

[0074] Step 1046c: Determine the current fixing temperature status based on the current ambient temperature and the set temperature.

[0075] In one embodiment of the present invention, the fixing temperature state includes low temperature, normal temperature, or high temperature. For example, when the current ambient temperature is less than a first temperature threshold, the current fixing temperature state is low temperature; when the current ambient temperature is greater than or equal to the first temperature threshold and less than a second temperature threshold, the current fixing temperature state is normal temperature; when the current ambient temperature is greater than or equal to the second temperature threshold, the current fixing temperature state is high temperature.

[0076] Step 1048c: Determine the printing temperature consumption corresponding to the fixing temperature status and printing speed based on the fixing temperature status, printing speed, and number of pages printed.

[0077] In one embodiment of the present invention, the printing temperature consumption corresponding to the fixing temperature state and printing speed is shown in Table 3 below.

[0078] Table 3

[0079]

[0080]

[0081] As shown in Table 3 above, when the printing speed is constant, the fixing temperature is low, and pages 1-10 are printed, the printing temperature consumption is -b1. b1 to b6 can be set according to actual conditions.

[0082] Step 106: Generate the fixing target temperature based on the fixing initial temperature, ambient temperature compensation value, and printing temperature consumption calculated.

[0083] Specifically, the fixing temperature compensation value, calculated from the initial fixing temperature, ambient temperature compensation value, and printing temperature consumption, is used to generate the fixing target temperature through the formula T = T0 + a + b. Here, T is the fixing target temperature, T0 is the initial fixing temperature, a is the ambient temperature compensation value, and b is the printing temperature consumption (b = 0 in cold mode).

[0084] Step 108: Print the image forming device according to the target temperature of the fixing device.

[0085] Specifically, the printing process uses the central thermistor (a thermistor used to control the temperature of the fixing target) to control the temperature of the fixing target.

[0086] In related technologies, after the driver sends a command to the image forming apparatus and the Time of Date (TOD) image is transmitted, the fusing assembly begins to heat up to the preheating temperature. Upon triggering by the front-end sensor, the fusing assembly heats up to the target temperature for printing. However, the time between the TOD image transmission to the front-end sensor is relatively short, meaning the fusing assembly cannot store heat in advance while in a slightly heated state. When printing on thicker special paper types such as labels, thick paper, and envelopes using slow manual feed, the difference in heat between the slightly heated and fully heated states is significant. Furthermore, the same strategy is used for printing two pages in a slightly heated state and for printing over two hundred pages in a fully heated state. When printing over 200 pages continuously in a fully heated state, the fusing assembly uses the temperature strategy that works well in a slightly heated state, resulting in a large amount of stored heat and slow internal heat dissipation, leading to severe image ghosting.

[0087] Because of the different types of paper, the preheating time of the fuser assembly will also be different. By preheating the fuser assembly, the fuser will store heat in advance, reducing the temperature difference between the fuser assembly in the slightly heated state and the fully heated state, thereby solving the problem of ghosting.

[0088] In one embodiment of the present invention, Figure 4 A timing diagram of a heating fixing assembly provided in an embodiment of the present invention is shown below. Figure 4 As shown, the specific process of the heating and fixing assembly is as follows: A drive command is sent to the image forming device, paper is simultaneously inserted, and when the manual feed sensor is triggered, the fixing assembly begins heating. After heating to the specified temperature and continuing for a given time, the TOD image is sent, and the fixing assembly proceeds according to... Figure 4 The control method shown performs heating printing, and after printing is completed, the paper is ejected and the fuser motor is turned off after a delay.

[0089] In one embodiment of the present invention, for special paper types such as thick paper, label paper, and envelope paper, the fixing component is preheated to store heat in advance, reducing the overall temperature difference between the machine in a slightly warm state and a fully warm state. This ensures that the image will not exhibit ghosting or poor fixing when printing two pages in a slightly warm state or printing more than two hundred pages in a fully warm state.

[0090] Figure 5 A timing diagram of a heating fixing assembly provided in related technologies, such as Figure 5As shown, when the last page of the paper is not yet past the eject sensor when the printer receives the next page command, the printer determines it is continuous printing. The paper ejection engine stops and then immediately restarts, and the printer immediately begins processing the next page command. During this process, the fuser target temperature remains constant. If the next page takes a long time to reach the fuser inlet (NIP) after the previous page has been ejected, the excessive heat generated by the prolonged heating at the fuser target temperature leads to ghosting.

[0091] In one embodiment of the present invention, Figure 6 A timing diagram of another heating fixing assembly provided in an embodiment of the present invention, as shown below. Figure 6 As shown, when the last page of the paper has not yet passed the ejection sensor when the printer receives the next page command, the printer determines that it is printing continuously. After the paper is ejected, the fusing heating stops, and the heating start point is set to the paper head trigger sensor. After triggering, heating immediately begins to reach the fusing target temperature. Because the time to maintain the fusing target temperature is shortened, the overall heat is reduced, avoiding ghosting in this scenario.

[0092] Figure 7 A timing diagram of another heating fixing assembly provided in the related art, such as Figure 7 As shown, after the engine starts, the ceramic plate begins to heat up. Due to the rapid temperature rise of the ceramic plate, the temperature reaches the target temperature in a short time. However, the paper has not yet reached the fusing assembly. Driven by the fusing motor, the fusing unit continues to idle and heat up. If the image forming device has been working for a long time and the printer is hot, the fusing unit will cause a large amount of heat to accumulate after idling at the target temperature for 4-6 seconds, resulting in ghosting in the image.

[0093] In one embodiment of the present invention, Figure 8 A timing diagram of another heating fixing assembly provided in an embodiment of the present invention, as shown below. Figure 8 As shown, after the engine starts, the ceramic plate begins to heat up to the target temperature -x℃. When the paper reaches the tip sensor, it is then heated to the target temperature. This avoids prolonged heating at the target temperature when the printer is hot, reducing heat accumulation and preventing ghosting.

[0094] In related technologies, the target fixing temperature = initial fixing temperature + environmental compensation temperature. The initial fixing temperature varies for different types of paper, while the environmental compensation temperature is the same for all types of paper. Table 4 shows the environmental compensation temperature for related technologies.

[0095] Table 4

[0096]

[0097] As shown in Table 4 above, due to the wide variety of paper types, the different materials, thicknesses, and heating times during printing, there are differences in the temperature difference between the cold and hot printing pages of different papers.

[0098] For example, 120g plain paper (base temperature 190℃) is relatively thin compared to other thicker papers. It requires less heat in a cold state, and the temperature difference between the fixing temperature when printing the first page in a cold state and the fixing temperature when printing the first page in a hot state is small. In Table 4, the fixing temperature of the first page printed when the image forming device is in a normal temperature environment, printing at low speed and in a cold state (≤A℃) is 200℃, and the fixing temperature of the first page printed in a hot state (>A℃) is 195℃. The temperature difference between the fixing temperatures in the cold and hot states is 5℃, which can meet the target fixing temperature for plain paper.

[0099] For example, label paper (base temperature 190℃) is relatively thick compared to other papers, requiring more heat in cold conditions. The temperature difference between the fixing temperature of the first page printed in cold conditions and the fixing temperature of the first page printed in hot conditions is large. In Table 4, the fixing temperature of the first page printed when the image forming device is in a normal temperature environment, printing at low speed and in cold conditions (≤A℃) is 200℃, and the fixing temperature of the first page printed in hot conditions (>A℃) is 195℃. The temperature difference between the fixing temperatures of cold and hot conditions is 5℃, which is not enough to meet the target fixing temperature of the label paper. The fixing temperature of the first page printed in cold conditions should be appropriately increased.

[0100] Since both of these paper types collect values ​​from a list of low-speed environmental compensation temperatures, the temperature control compatibility of the above scheme is poor and cannot meet the requirements of all paper types.

[0101] In this application, a fixing target temperature can be generated based on the fixing temperature compensation value calculated from the initial fixing temperature, the ambient temperature compensation value, and the printing temperature consumption. Different types of paper have different initial fixing temperatures, all papers have the same ambient temperature compensation, but different papers have different fixing temperature compensation values. Table 4 shows the ambient temperature compensation table for embodiments of this invention, as shown in Table 5 below.

[0102] Table 5

[0103]

[0104] As shown in Table 5 above, for example, the thickness of 120g plain paper (base temperature 190℃) is relatively thin compared to other thicker papers. It requires less heat in the cold state, and the temperature difference between the fixing temperature when printing the first page in the cold state and the fixing temperature when printing the first page in the hot state is small. In Table 4, when the image forming device is in a normal temperature environment, printing at low speed and in the cold state (≤A℃), the fixing temperature of the first page is 200℃, and the fixing temperature of the first page in the hot state (>A℃) is 195℃. The fixing temperature compensation value of plain paper is 0, and the temperature difference between the fixing temperature in the cold and hot states is 5℃, which can meet the fixing target temperature of plain paper.

[0105] In the technical solution provided by this invention, an initial fixing temperature is set according to the paper type and printing conditions; an ambient temperature compensation value and printing temperature consumption are obtained to calculate a fixing temperature compensation value; a fixing target temperature is generated based on the fixing temperature calculated from the initial fixing temperature, the ambient temperature compensation value, and the printing temperature consumption; and the image forming apparatus is controlled to print according to the fixing target temperature. This technical solution allows for switching between suitable fixing target temperatures based on different paper types and printing conditions, enabling the setting of appropriate fixing temperatures for the image forming apparatus under different paper types and printing conditions, thereby improving image forming quality.
