Description

Technical Field

[0001] This application relates to the field of image forming technology, and particularly to a printing control method, apparatus and device. Background Art

[0002] In the standby stage, the fusing module of the image forming apparatus maintains at temperature T1. When a job task is received, the Laser Scanning Unit (LSU) first pre-starts at a preset speed V1. When the image forming apparatus finishes parsing the job task, the image forming apparatus enters the printing state. At this time, the LSU changes speed to the working speed V2 set by the current job task, and at the same time the fusing module (including the heating roller and the pressure roller) heats up to the printing target temperature T2. After the LSU changes speed to V2 and operates stably, the image forming apparatus then determines whether the fusing temperature (the surface temperature of the heating roller) reaches temperature T3 (T1 < T3 < T2). After reaching temperature T3, paper feeding is performed until the paper is discharged, thus completing the printing of the first page time. The time taken for the fusing module to heat from T1 to T2 is relatively long, resulting in a relatively long first page printing time each time a job task is processed, which affects the working efficiency of users.

[0046] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0047] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0048] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0049] 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.

[0050] The printing control method of this application embodiment is mainly applied to image forming apparatuses, including devices such as printers, copiers, scanners, and fax machines. The technical solution of this application embodiment is described below using a printer as an example.

[0051] like Figure 1 As shown, the main components of the printer may include: a photosensitive drum 11, a charging roller 12, a laser scanning unit 13, a developing roller 14, a paper tray 15, a transfer roller 16, a heating roller 17, a pressure roller 18, and a cleaning device 19.

[0052] The charging roller 12 is used to charge the photosensitive drum 11, covering a layer of negative charge on the surface of the photosensitive drum 11, and at the same time clearing (covering) the charge of the previous cycle. The laser scanning unit 13 is used to emit a laser beam to the photosensitive drum 11, and the area on the surface of the photosensitive drum 11 irradiated by the laser beam becomes positively charged. The developing roller 14 contacts the toner. When the control voltage of the developing roller 14 is set to a specific value, the developing roller 14 has magnetism and can attract the surrounding toner. As the developing roller 14 continues to rotate, the toner will contact the surface of the photosensitive drum 11, and the toner is negatively charged. The area of the photosensitive drum 11 irradiated by the laser beam is positively charged and can attract the toner, while the area not irradiated by the laser beam is negatively charged and cannot attract the toner. After development, an image will appear on the surface of the photosensitive drum 11. Printer paper is stored in the paper tray 15, and the printer paper is transported in the direction of the arrow and passes between the photosensitive drum 11 and the transfer roller 16. The transfer roller 16 carries a positive charge and can attract the toner with the formed image on the photosensitive drum 11 onto the printer paper, and an image appears on the printer paper. The printer paper passes through the heating roller 17 and the pressure roller 18, and the toner is melted and fixed on the printer paper by heating and extrusion. The cleaning device 19 removes the excess toner from the surface of the photosensitive drum 11 to prevent the excess toner from leaking onto the printer paper.

[0053] In the above device, the heating roller 17 and the pressure roller 18 can be regarded as a fixing module, which is used to heat and fix the toner on the printer paper. A heating device (such as a halogen lamp) is provided in the heating roller 17 to heat the fixing module. When the printer is in the standby state, the fixing module will maintain at the temperature T1. When receiving a job task, the printer enters the pre-start. During the pre-start process, the printer analyzes the job task, and the motor in the laser scanning unit 13 will run at the preset speed V1. When the job task analysis is completed, the printer enters the printing state. At this time, the motor of the laser scanning unit 13 will change speed to the printing speed V2 required by the job task, and at the same time the fixing module will heat at the printing target temperature T2. After the motor of the laser scanning unit 13 completes the speed change and runs stably at V2, the printer judges whether the fixing temperature, that is, the actual temperature of the fixing module, reaches T3. After confirming that it reaches T3, the paper feeding starts until the paper is discharged and the first page printing is completed.

[0054] Among them, T1 < T3 < T2. The paper feeding starts when the actual temperature of the fixing module reaches T3. When the printer paper is transported to the fixing module, the actual temperature of the fixing module usually reaches T2, and the fixing operation can be normally performed. V2 mainly includes the speed values of slow printing and normal speed printing. The time taken for the motor of the laser scanning unit 13 to change speed from 0 to V2 is longer than the time taken to change speed from V1 to V2. For example, when slow printing, the speed value of V2 is 3 (ignoring the unit), and when normal speed printing, the speed value of V2 is 5, then the speed value of V1 can be set to 4. Compared with changing speed from 0 to 3 or 5, changing speed from 4 to 3 or 5 is faster, which can shorten the printing preparation work.

[0055] Figure 2 This example illustrates the first page printing process for a printer. The user submits a job assignment via an electronic device (such as a mobile phone or computer) with a printer driver installed. When the printer's firmware recognizes the job assignment, it sends a pre-start command to the engine and begins parsing the job. Upon receiving the pre-start command, the engine controls the LSU motor to pre-start at speed V1. After parsing the job, the firmware sends a print command and a paper feed command to the engine. Upon receiving the print command, the engine controls the LSU motor to change speed to V2 and simultaneously controls the heating device to heat the fuser module at the target temperature T2℃. The time required for the LSU motor to stabilize at V2 speed is time 1. After time 3, the fuser module reaches the printer motor's operating temperature. At this temperature, the printer motor starts, driving the fuser module to rotate, ensuring even heating. After time 4, the fuser module reaches T3℃ and begins paper feeding. After time 5, the fuser module reaches T2℃, and the first sheet of paper has typically been transferred to the fuser module, which then performs the fusing operation. The time required from the start of paper feeding to the end of first page printing is duration 6. The time required from the data firmware sending the print pre-start command to the end of first page printing is the sum of durations 1, 3, 4, and 6. The times spent in each stage are only illustrative examples; in other embodiments, the time spent printing the first page may be other values.

[0056] Considering the working nature of the fuser module, its heating device usually has power limitations, which causes the fuser module to take too long to heat from T1 to T2 temperature, resulting in a longer first page printing time and affecting the user experience.

[0057] To address the aforementioned issues, this application provides a printing control method in which the printer pre-activates the heating device of the fuser module when parsing the job task, and determines the heating power of the heating device by comprehensively considering the difference between the actual temperature and the target temperature of the fuser module and the ambient temperature, thereby enabling the fuser module to heat up rapidly and shortening the first page printing time.

[0058] Figure 3 This is a flowchart illustrating a printing control method provided in an embodiment of this application. The method can be applied to printers, such as... Figure 3 As shown, the method may include:

[0059] Step 301: During the parsing operation of the job task issued by the user, the first heating power is determined based on the first target temperature and the actual temperature of the fixing module, and the heating device is controlled to heat the fixing module with the first heating power.

[0060] Step 302: When the job task is parsed, the second heating power is determined based on the second target temperature and the actual temperature of the fixing module, and the heating device is controlled to heat the fixing module with the second heating power so that the heated fixing module can print the job task.

[0061] Users can send job tasks to the printer via the print driver. Upon receiving the job task, the printer pre-parses it to identify it as a printable task. When the printer recognizes the job task as printable, it parses it. Simultaneously, the printer's firmware sends a pre-start command to the engine to immediately activate the LSU motor and heating unit, allowing the heating unit to preheat the fuser module. During the job task parsing process, the printer controls the heating unit to heat the fuser module at a first heating power. This first heating power is determined by a first target temperature and the actual temperature of the fuser module. The first target temperature is a temperature reference value. The heating unit continues to heat the fuser module until the actual temperature reaches the first target temperature, at which point it stops heating. The first target temperature can be set to the same as T3 mentioned above, or it can be set to other reasonable values, such as temperatures lower than T3. When the printer finishes parsing the job, the firmware sends a print command to the engine. Upon receiving the print command, the printer enters printing mode. The printer continues heating the fuser module, targeting the second target temperature. When the actual temperature of the fuser module reaches the third target temperature, the printer starts feeding paper. When the actual temperature of the fuser module reaches the second target temperature, the print job begins, and the first page is output. The first target temperature is lower than the third target temperature, and the third target temperature is lower than the second target temperature. The second target temperature is the temperature required for printing.

[0062] During the preheating phase of the fuser module, the printer determines the first heating power based on the temperature difference between the actual temperature of the fuser module and the first target temperature. The first heating power is positively correlated with this temperature difference; the larger the temperature difference, the greater the first heating power. During the heating process of the fuser module, the printer acquires the actual temperature of the fuser module in real time and adjusts the value of the first heating power accordingly, achieving stepped heating of the fuser module. The closer the actual temperature of the fuser module is to the first target temperature, the lower the power of the heating device.

[0063] When the printer finishes analyzing the job, it can determine the second heating power based on the second target temperature and the actual temperature of the fuser module, and control the heating device to heat the fuser module at the second heating power. The second target temperature can be considered as T2 mentioned above, and the first target temperature is lower than the second target temperature. During the process of the printer controlling the heating device to heat the fuser module at the second heating power, when the actual temperature of the fuser module reaches the third target temperature (which can be considered as T3 mentioned above), paper feeding begins. When the actual temperature of the fuser module reaches the second target temperature, the job is printed. Because the fuser module has been preheated, the time it takes for the fuser module to heat to the third target temperature and the second target temperature is shortened, thus shortening the first page printing time. Furthermore, starting paper feeding at the third target temperature ensures that when the paper reaches the fuser module, the actual temperature of the fuser module has reached the second target temperature, thereby ensuring print quality during the job printing and reducing printing problems such as ghosting and blurring.

[0064] In one optional embodiment, in addition to determining the first heating power based on the temperature difference, the printer can also consider the influence of ambient temperature on heating efficiency. Therefore, the first heating power can be determined comprehensively based on the first target temperature, the ambient temperature, and the actual temperature of the fusing module. Specifically, the printer first determines a heating power strategy table based on the ambient temperature, which contains a mapping relationship between temperature difference and heating power. Then, the printer determines the temperature difference between the actual temperature of the fusing module and the first target temperature, and then determines the corresponding heating power in the heating power strategy table based on this temperature difference, which is used as the first heating power.

[0065] When determining the corresponding heating power in the heating power strategy table based on the temperature difference, the heating power percentage can be determined first based on the temperature difference between the actual temperature of the fixing module and the first target temperature. Then, the heating power percentage is multiplied by the total power to determine the corresponding heating power.

[0066] Generally, the higher the ambient temperature, the higher the heating efficiency of the heating device, and the faster the temperature of the fuser module rises. Conversely, the lower the ambient temperature, the slower the temperature of the fuser module rises. The heating power determined by the same temperature difference in a high-temperature environment is usually lower than the heating power determined in a low-temperature environment. The printer can preset multiple temperature ranges and configure corresponding heating power strategy tables for different temperature ranges. Optionally, the temperature range may include a high-temperature range, a normal-temperature range, and a low-temperature range. (1) When the ambient temperature is in the high-temperature range, the printer can determine the heating power based on the first heating power strategy table. (2) When the ambient temperature is in the normal-temperature range, the printer can determine the heating power based on the second heating power strategy table. (3) When the ambient temperature is in the low-temperature range, the printer can determine the heating power based on the third heating power strategy table. Among them, the temperature range covered by the high-temperature range is higher than that of the normal-temperature range, and the temperature range covered by the normal-temperature range is higher than that of the low-temperature range.

[0067] The following description uses specific embodiments, and the first heating power strategy table is shown in Table 1:

[0068]

[0069] Table 1

[0070] Under the first heating power strategy table, when the temperature difference Diff > 3K℃, the heating device uses full power. When 3K℃ >= Diff > 2K℃, the heating device uses 67% of its full power. When 2K℃ >= Diff > 1K℃, the heating device uses 50% of its full power. When 1K℃ >= Diff > 0℃, the heating device uses 33% of its full power. When Diff <= 0℃, the heating device uses 0% of its full power (i.e., heating stops). Here, K is a unit value; in practical scenarios, K can take the values ​​of 1, 2, or other reasonable values ​​without restriction. Table 1 is only an exemplary description of the first heating power strategy table. In other embodiments, the temperature difference and heating power in the first heating power strategy table may adopt other mapping relationships.

[0071] The second heating power strategy table is shown in Table 2:

[0072]

[0073] Table 2

[0074] Under the second heating power strategy table, when the temperature difference Diff > 2K℃, the heating device uses full power. When 2K℃ >= Diff > 1K℃, the heating device uses 67% of its full power. When 1K℃ >= Diff > 0℃, the heating device uses 50% of its full power. When Diff <= 0℃, the heating device uses 0% of its full power. In the third heating power strategy, each temperature difference corresponds to full power heating.

[0075] It is understandable that when the ambient temperature is in the high-temperature range, the heating efficiency of the heating device is high, and the heating power does not need to be too high. After the printer determines the temperature difference, it can look up the corresponding heating power in Table 1. When the ambient temperature is in the normal-temperature range, the heating efficiency of the heating device is low, and the heating power should be appropriately increased. After the printer determines the temperature difference, it can look up the corresponding heating power in Table 2. When the ambient temperature is in the low-temperature range, the heating efficiency of the heating device is the lowest, and the printer uses full-power heating.

[0076] In this embodiment, the printer first determines the heating power strategy table matching the current ambient temperature, and then determines the heating power in the heating power strategy table based on the temperature difference between the first target temperature and the actual temperature of the fusing module. This can further improve the heating efficiency of the fusing module and thus shorten the first page printing time.

[0077] In one optional embodiment, when the printer determines the heating power strategy table, it considers not only the ambient temperature but also the actual temperature of the fusing module (also known as the fusing temperature). Specifically, when the fusing temperature does not reach the first target temperature, the printer can continue to determine the first heating power based on the ambient temperature and temperature difference. When the fusing temperature reaches the first target temperature, the printer will uniformly use the first heating power strategy table thereafter. The specific operation is as follows: (1) When the ambient temperature is in the low temperature range and the fusing temperature does not reach the first target temperature, the printer uses the full power in the third heating power strategy table for heating. When the fusing temperature reaches the first target temperature, the printer will switch to using the first heating power strategy table (i.e., the example in Table 1 above). (2) When the ambient temperature is in the normal temperature range and the fusing temperature does not reach the first target temperature, the printer uses the second heating power strategy table (i.e., the example in Table 2 above). When the fusing temperature reaches the first target temperature, the printer will switch to using the first heating power strategy table. (3) When the ambient temperature is in the high temperature range, the printer will use the first heating power strategy table throughout. It's understandable that once the fixing temperature reaches the first target temperature, subsequent fixing temperatures will fluctuate around that temperature. When the fixing temperature exceeds the first target temperature, the heating device stops heating; when the fixing temperature cools down below the first target temperature, the heating device restarts heating. During this process, even if the printer is in a low-temperature environment, the heating device does not need to use high heating power. Furthermore, due to the proximity to the paper feed, the fixing module should not use high heating power to avoid temperature overshoot.

[0078] In one optional embodiment, after the actual temperature of the fusing module reaches the first target temperature, when the printer has finished parsing the job task, a second heating power can be determined based on the second target temperature, the actual temperature of the fusing module, and the first heating power strategy table. The first heating power strategy table contains a mapping relationship between temperature differences and heating power. Specifically, the corresponding heating power can be found in the first heating power strategy table based on the temperature difference between the actual temperature of the fusing module and the second target temperature, and used as the second heating power.

[0079] In this embodiment, the printer determines the heating power based on a combination of the fixing temperature and the ambient temperature. This improves the heating efficiency of the fixing module, avoids resource waste caused by high-power heating, and prevents temperature overshoot during the fixing process.

[0080] In one optional embodiment, the printer may pre-parse the job task before parsing it to assess the estimated parsing time of the current job task. When the estimated parsing time is less than a preset threshold time, the heating power retrieved from the heating power strategy table is increased, and the increased heating power is determined as the first heating power. It is understood that if the job task parsing time is short, the heating time of the fixing module will also be short, and the heating device should increase the heating power on top of the original heating power to allow the fixing temperature to reach the first target temperature more quickly. Optionally, the increase in heating power can be determined based on the difference or ratio between the estimated parsing time and the preset threshold time. When the estimated parsing time is less than the preset threshold time, the larger the difference in time, the larger the increase in heating power; the smaller the difference in time, the smaller the increase in heating power.

[0081] After applying the printing control method of the embodiments of this application, the first page printing process can be referred to Figure 4 Example. When the printer's firmware issues a print pre-start command, the LSU motor pre-starts at speed V1, while the heating element heats at the target temperature T4℃, which can be considered the first target temperature mentioned above. After the printer parses the job, it issues a print command, the LSU motor changes speed to V2, and the heating element heats at the target temperature T2℃. Due to the pre-heating of the fuser module, after the LSU motor stabilizes, it reaches T3℃ after time 4, and after time 5, the fuser module reaches T2℃, and printing begins. The time required from issuing the print pre-start command to the end of the first page printing is the sum of time 1, time 4, and time 6. Figure 4 Each duration and Figure 2 The duration is the same for all parts. Compared to Figure 2 First page printing time in the text Figure 4 The first page printing time has been shortened by 3.

[0082] Figure 5 This is a flowchart illustrating another printing control method provided in an embodiment of this application. Figure 5 As shown, the method may include:

[0083] Step 501: The image forming apparatus is in standby mode, and the fixing temperature is maintained at T1℃.

[0084] In standby mode, the image forming apparatus maintains a temperature of T1. When the user sends a job task using a terminal (or computer), the image forming apparatus will recognize and begin to parse the job. At this time, the device is still in a ready state. After receiving the job signal, the data firmware sends a print pre-start command to the engine.

[0085] In step 502, the image forming apparatus recognizes the job task and pre-starts the LSU at speed V1, while the fixing module preheats at T4°C and the first heating power.

[0086] When the engine receives a print pre-start command, it only controls the LSU and fuser modules. The LSU pre-starts at speed V1, and the fuser module pre-starts at the target temperature T4 and the first heating power. The engine adjusts the first heating power in real time based on the ambient temperature and the fuser temperature to perform the first stage of heating. T4℃ is the aforementioned first target temperature.

[0087] Step 503: Determine whether the job task has been parsed. If yes, proceed to step 504; otherwise, continue with the original operation.

[0088] Step 504: The LSU speed is changed to V2, and the fixing module heats at T2℃ and the second heating power.

[0089] At this point, the LSU enters speed change V2, while the fixing module continues heating with T2 (the aforementioned second target temperature) as the target; that is, the fixing module enters the second stage of heating. After the LSU enters speed change V2, it is necessary to wait for the LSU motor to stabilize before imaging and printing can begin.

[0090] Step 505: Check if the LSU motor is stable and if the fixing temperature has reached T3℃. If yes, proceed to step 506; otherwise, continue the check.

[0091] Step 506: Start paper feeding and execute the task.

[0092] Paper feeding begins only after temperature T3 is reached. The image forming device prints the job when the fixing module reaches temperature T2, completing the first page printing.

[0093] For other details, please refer to Figure 1 Description of the process.
