Technical Field

[0002] When in an environment with high humidity and low temperature, such as rainy weather, the environment of the standby paper (printing paper) and the paper input box is very humid. When performing imaging tasks under such conditions, the standby paper is prone to curling and the adhesion of toner is reduced, which may cause problems such as blurred imaging images, affecting the quality of operation.

However, humidity detection is difficult to achieve high accuracy, and the heating time may be too long or too short, making it difficult for the heated paper to reach an ideal state.

[0051] For a better understanding of the technical solutions of this specification, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0052] It should be clear that the described embodiments are only a part of the embodiments of this specification, rather than all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by this specification.

[0053] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit this specification. The singular forms "a", "the" and "said" used in the embodiments of the present invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0054] In view of the problems that in a humid environment or a cold environment, the moisture of the paper is affected, the toner adhesion will decrease, resulting in paper jams and poor image quality, etc., the embodiments of the present invention provide an image forming device and a paper heating method. The image forming device can be a printer, a copier, a fax machine, a scanner, and a multifunctional all-in-one machine integrating functions such as printing, copying, faxing, and scanning. Its function is to print images or texts on an imaging medium.

[0055] Figure 1 A schematic structural diagram of an image forming device provided by an embodiment of the present invention. As Figure 1 shown, the device may include: a first detection device 110, a second detection device 120, a controller 130, a heating device 140, a paper feed roller 150, a paper feed cassette 160, and a main control panel 170.

[0056] The first detection device 110 may be composed of a humidity sensor and is arranged in the paper feed tray 160 to detect the ambient humidity value in the paper feed tray 160; the second detection device 120 may be composed of a gravity sensor and is arranged below the paper to be used in the paper feed tray 160 to detect the paper gravity value of the paper to be used in the paper feed tray 160; the controller 130 is respectively connected to the first detection device 110, the second detection device 120 and the heating device 140 to realize the control between the devices; the heating device 140 is arranged in the paper feed roller 150 to heat the paper to be used; an external main control panel 170 is arranged on the controller 130, and the main control panel 170 can display the ambient humidity value, the paper gravity value and the current humidity level, and can also realize the interaction with the user.

[0057] After the image forming apparatus is started, a user may send a job task to the controller 130 through the operation panel 170 or a host device connected to the image forming apparatus. The controller 130 cyclically activates the first detection device 110 within a predetermined time. For example, the controller controls the first detection device 110 to start at intervals of five minutes. After the first detection device 110 is activated, it obtains the ambient humidity value in the paper feed cassette 160 in real time and sends the ambient humidity value to the controller 130. The controller 130 may preset a first threshold and a second threshold, where the first threshold is greater than the second threshold. For example, the first humidity value is set to 55%, and the second humidity value is set to 30%. When the controller 130 detects that the ambient humidity value does not exceed the second threshold, it may determine that the humidity in the current paper feed cassette 160 is low and has little impact on the execution of the job task. The controller 130 does not make other responses, and "The environment of the paper feed cassette 160 is good" may be displayed on the operation panel 170. When the controller 130 detects that the ambient humidity value exceeds the second threshold and does not exceed the first threshold, it may determine that the humidity in the current paper feed cassette 160 can already have a certain impact on the execution of the job task. "High humidity" may be displayed on the operation panel 170, and the controller 130 controls the heating device 140 to start. In addition, in order to enable the heating device 140 to heat the standby paper at a suitable temperature, the controller 130 may determine the corresponding heating temperature according to the ambient humidity value, and the heating device 140 adjusts the power according to the heating temperature sent by the controller 130 and heats the standby paper at the heating temperature. When it is detected that the ambient humidity value exceeds the first threshold, "High humidity" may be displayed on the operation panel 170, and the controller 130 controls the second detection device 120 to start. The second detection device 120 obtains the paper gravity value of the standby paper in real time and sends the paper gravity value to the controller 130. The controller 130 will add the influencing factor of the paper gravity value on the basis of the original ambient humidity value and calculate the heating temperature according to the ambient humidity value and the paper gravity value together. It can be understood that the heating temperature of the heating device should be adapted to the humidity of the standby paper. The higher the humidity, the higher the heating temperature is required to remove the moisture of the standby paper within the same time. In an environment with low humidity, a high heating temperature will instead make the standby paper too dry and affect the imaging effect. Therefore, the more accurate the heating temperature is, the better the heating effect is. When the humidity of the standby paper is high, the weight of the paper itself will also increase. Compared with the heating temperature calculated only according to the ambient humidity value, the heating temperature calculated based on the paper gravity value and the ambient humidity value is more accurate and the heating effect is better. In addition, the controller 130 controls the second detection device 120 to start only when it detects that the ambient humidity value exceeds the first threshold, which can save power and the processing resources of the controller 130. If the ambient humidity value does not exceed the first threshold and the humidity of the standby paper is low, there is no need for a very high accuracy of the heating temperature, and the second detection device 120 may not be activated temporarily.

[0058] In one implementation, the second detection device 120 is disposed below the paper to be used, and can obtain the first gravity value of all the papers to be used in the paper feed cassette 160. During the execution of the operation task, when a paper to be used is conveyed to the image forming apparatus, the second detection device 120 can obtain the second gravity value of the remaining papers to be used in the paper feed cassette 160. Subtracting the second gravity value from the first gravity value can obtain the paper gravity value of each paper to be used. In an actual scenario, when a paper to be used reaches the paper feed roller 150, the controller 130 has completed the calculation of the paper gravity value of the paper to be used, so as to determine the heating temperature, and corresponding heating temperature can be realized for each paper to be used, improving the heating effect.

[0059] In one embodiment, the heating device 140 can be disposed inside the paper feed roller 150. When the heating device is not started, the paper feed roller 150 only serves as a conveying device for the paper to be used, and conveys the paper to be used from the paper feed cassette 160 to the image forming apparatus. As Figure 1 shown, the direction indicated by the arrow above the paper to be used is the conveying direction of the paper to be used. When the heating device 140 is heating, the paper feed roller 150 and the heating device 140 can form a heating roller, which not only has the function of conveying paper, but also can heat the paper to be used during the process of conveying the paper to be used from the paper feed cassette 160 to the image forming apparatus. Here, the heating device 140 can be realized by a heating resistor. During the execution of the operation task, as long as the controller 130 detects that the current ambient humidity value exceeds the second threshold, the heating device 140 will be continuously turned on to ensure that each paper to be used has its moisture removed when it is conveyed to the image forming apparatus, and will not affect the imaging.

[0060] In one embodiment, in addition to being disposed inside the paper feed roller 150, the heating device 140 may also be disposed inside the paper feed cassette 160. When the controller 130 detects that the ambient humidity value exceeds the second threshold, the heating device is activated to heat the entire paper feed cassette 160 and the standby paper in the paper feed cassette 160. Here, the heating device can be implemented using an existing drying device or a blowing device. If the heating device 140 is disposed inside the paper feed cassette 160, the controller 130 can set the heating time point before the execution of the operation task. For example, when the controller 130 detects that the ambient humidity value exceeds the second threshold, the execution of the operation task is paused, and the preheating mode is entered. The heating device 140 is controlled to preheat the paper feed cassette 160 and the standby paper in the paper feed cassette 160. When it is detected that the ambient humidity value drops below the second threshold, the preheating ends, and the main control panel 170 displays "Good environment", and the controller 130 controls the resumption of the execution of the operation task. In another embodiment, the controller 130 can also periodically detect the ambient humidity value in the paper feed cassette 160, and when it detects that the ambient humidity value exceeds the second threshold, control the heating device 140 to preheat the paper feed cassette 160 and the standby paper in the paper feed cassette 160 until the ambient humidity value drops below the second threshold. Through intermittent detection and heating, the standby paper in the paper feed cassette 160 can be prevented from being affected by moisture, and electric energy can be saved. The preheating mode is suitable for scenarios with a large printing task volume. If a certain operation task only uses a small number of standby papers, it is preferred to use a heating roller for heating.

[0061] In one embodiment, when the image forming apparatus is in a cold environment, the adhesion degree of the toner decreases, which also affects the clarity of the imaging picture. Based on the above influencing factors, the image forming apparatus may also be provided with a temperature sensor for detecting the current ambient temperature value and sending the ambient temperature value to the controller 130. When the controller 130 detects that the ambient temperature value is lower than a certain preset threshold, the heating device 140 is turned on to heat the standby paper. The heating temperature can be calculated only based on the ambient temperature value, or can be determined by adding the ambient humidity value and the paper gravity value.

[0062] In one embodiment, when the image forming apparatus is operating in a specific month, the standby paper usually has a relatively high humidity value. For example, during the plum rain season from April to June in the south, it is usually rainy continuously, and the average humidity is above 77%. Compared with other months, the humidity increases significantly. Considering the above influencing factors, the user can set the humid time in advance through the main control panel 170. When the controller 130 detects that the current time is within the humid time range, it can increase the frequency of periodically turning on the first detection device 110 and the second detection device 120. Moreover, the controller 130 can omit the step of determining whether the ambient humidity value exceeds the first threshold or the second threshold, directly control the first detection device 110 and the second detection device 120 to start, and determine the heating temperature according to the first detection device and the second detection device, and control the heating device 140 to heat the standby paper at this heating temperature. Setting the humid time can optimize the heating process of the image forming apparatus, enabling the heating device 140 to be turned on more promptly and determining a suitable heating temperature more quickly.

[0063] In one embodiment, considering that each startup of the heating device 140 consumes a relatively large amount of electrical energy, the controller 130 can also determine the execution frequency of the job task. If the execution frequency is high, the usage times of the heating device 140 are increased; if the execution frequency is low, the usage times of the heating device 140 are decreased. For example, the controller 130 can determine the number of times the job task has been executed in the past period. If the number of times of executing the job task is greater than the preset threshold, then after receiving the job task, the controller 130 executes the relevant heating process, that is, turns on the first detection device 110 to detect the ambient humidity value and a series of subsequent operations. If the number of times of executing the job task does not exceed the preset threshold, then after receiving the job task, the controller 130 does not execute the relevant heating process. In addition to the above method, the controller 130 can also adjust the second threshold or the first threshold according to the number of times the job task has been executed in the past period. For example, if the execution times are high, the second threshold is decreased, and it is easier for the ambient humidity value to exceed the second threshold, and the heating device 140 is turned on more frequently. If the execution times are low, the second threshold is increased, and the number of times the heating device 140 is turned on will be reduced. Determining the startup frequency of the heating device 140 based on the execution frequency of the job task can make the use of the heating device 140 more economical and improve the user experience.

[0064] In another embodiment, when the controller 130 detects that the number of job tasks executed within the past first time period exceeds a preset threshold, the controller 130 may further increase the heating temperature or heating frequency of the heating device 140. It will be appreciated that a higher number of job tasks executed within the past first time period indicates that the image forming apparatus is currently being used more frequently. To reduce the energy consumption caused by frequently activating the heating device 140, the heating efficiency of the heating device 140 may be increased (by increasing the heating temperature or heating frequency) when heating conditions are met, thereby reducing the number of times the heating device 140 is used without affecting the ambient humidity in the paper feed tray 160. Furthermore, frequently turning the heating device 140 on and off may shorten its service life, hindering the user experience.

[0065] In an embodiment of the present invention, the image forming device can more accurately calculate the appropriate heating temperature based on the ambient humidity value and the paper gravity value, so that the quality of the heated paper to be used is better, and the clarity of the imaging picture is effectively improved; by setting the humidity time, the heating process can be optimized, so that the heating device can be started more promptly; by adjusting the heating temperature or heating time or heating power or usage frequency of the heating device according to the number of executions of the job task, it can effectively save electricity and improve user experience.

[0066] Figure 2 This is a flow chart of a paper heating method provided by an embodiment of the present invention. This method can be applied to Figure 1 A controller for an image forming device such as Figure 2 As shown, this may include:

[0067] Step 201: Periodically start the first detection device and obtain the ambient humidity value in the paper feed box.

[0068] Step 202: If the ambient humidity value exceeds the first threshold, the second detection device is turned on to obtain the paper gravity value of the paper to be used in the paper feed box.

[0069] Step 203 : controlling the heating device to start according to the acquired environmental humidity value and paper weight value, and instructing the heating device to heat the paper to be used in the paper feed box.

[0070] In one embodiment, if the heating device is disposed in the paper feed roller, when the controller detects that the ambient humidity exceeds a first threshold, the controller may determine a first heating temperature based on the ambient humidity and the paper weight, then control the heating device to activate and instruct the heating device to heat the paper at the first heating temperature while the paper is being conveyed from the paper feed tray to the image forming apparatus. If the heating device is disposed in the paper feed tray, when the controller detects that the ambient humidity exceeds the first threshold, the controller may determine a second heating temperature based on the ambient humidity and the paper weight, then control the heating device to activate and instruct the heating device to heat the paper feed tray and the paper in the paper feed tray at the second heating temperature.

[0071] In one embodiment, if the heating device is disposed in the paper feed roller, when the controller detects that the ambient humidity value exceeds the second threshold and does not exceed the first threshold, the third heating temperature can be determined according to the ambient humidity value and the paper gravity value, and then the heating device is controlled to start, and it is indicated that the heating device heats the standby paper at the third heating temperature during the process of the standby paper being conveyed from the paper cassette to the image forming apparatus. If the heating device is disposed in the paper cassette, when the controller detects that the ambient humidity value exceeds the first threshold, the fourth heating temperature can be determined according to the ambient humidity value and the paper gravity value, and then the heating device is controlled to start, and it is indicated that the heating device heats the paper cassette and the standby paper in the paper cassette at the fourth heating temperature. The first threshold and the second threshold can be set in advance by the user according to actual needs.

[0072] In one embodiment, the user can preset the humid time. If the controller determines that the current time is within the humid time range, the frequency of periodically turning on the first detection device and the second detection device increases, and the ambient humidity value in the paper cassette and the paper gravity value in the paper cassette are acquired.

[0073] In one embodiment, the controller can also adjust the usage frequency of the heating device according to the execution frequency of the job task. The specific steps can include: determining the number of times the job task is executed in the past first time period with the current time as the end time. If the number of times the job task is executed is greater than the preset threshold, the heating temperature or the heating frequency of the heating device is increased.

[0074] Figure 3 This is a flowchart of another paper heating method provided by an embodiment of the present invention. As Figure 3 shown, the method can include:

[0075] Step 301, detecting the ambient humidity value.

[0076] The image forming apparatus can periodically detect the ambient humidity value in the paper cassette or detect the ambient humidity value when receiving a job task.

[0077] Step 302, determining whether the ambient humidity value is greater than the second threshold.

[0078] If the ambient humidity value is greater than the second threshold, go to step 303 for the next detection. If the ambient humidity value does not exceed the second threshold, go to step 308 to directly convey the standby paper.

[0079] Step 303, determining whether the ambient humidity value is greater than the first threshold.

[0080] If the ambient humidity value is greater than the first threshold, go to step 304 to detect the paper gravity value. If the ambient humidity value does not exceed the first threshold, go to step 306.

[0081] Step 304: Detect the paper weight.

[0082] Step 305: Determine the heating temperature based on the ambient humidity value and the paper weight value.

[0083] When the ambient humidity value exceeds a first threshold, the heating temperature is calculated according to the ambient humidity value and the paper weight value.

[0084] Step 306: Determine the heating temperature based on the ambient humidity value.

[0085] When the ambient humidity value does not exceed the first threshold, the heating temperature is determined only according to the ambient humidity value.

[0086] Step 307: heating the paper to be used based on the heating temperature.

[0087] Step 308: The waiting paper is delivered.

[0088] Through the above process, moisture can be removed from the paper to be used, ensuring that the image is clear and visible.
