Description

Technical Field

[0001] This invention relates to the field of image forming, and more particularly to a method and apparatus for controlling the paper delivery interval in printing. Background Technology

[0002] Image forming equipment includes a paper feed roller and a transfer roller. The paper feed roller transports the printing paper from the paper tray to the transfer roller. When the beginning of the printing paper reaches the transfer roller, the paper feed roller pauses operation and resumes transporting the next sheet after a certain time interval. In some printing scenarios, the length of the printing paper is less than the distance between the paper feed roller and the transfer roller. When the end of the printing paper leaves the paper feed roller, the beginning of the paper has not yet reached the transfer roller, and the paper feed roller continues to operate, transporting the next sheet. When the printing paper reaches the transfer roller, the interval between two adjacent sheets is small, which can easily lead to paper jams. Summary of the Invention

[0060] Figure 4 This is a schematic diagram of the structure of an electronic device provided in an embodiment of the present invention. Detailed Implementation

[0061] To better understand the technical solutions in this specification, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0062] It should be understood that the described embodiments are merely some, not all, of the embodiments in this specification. All other embodiments obtained by those skilled in the art based on the embodiments in this specification without inventive effort are within the scope of protection of this specification.

[0063] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of this specification. 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.

[0064] In this embodiment of the invention, the structure of the image forming device (such as a printer or copier) can be as follows: Figure 1 As shown, the internal components include a paper feeding roller 101, a separating roller 102, a sensor 103, a first conveying roller 104, a sensor 105, and a second conveying roller 106. Figure 1 As shown, when the image forming apparatus performs a printing task, the printing paper passes sequentially through the feed roller 101, the separation roller 102, the sensor 103, the first conveyor roller 104, and the sensor 105, finally reaching the second conveyor roller 106. The second conveyor roller 106 (also called the correction roller) is used to convey and correct the printing paper. The image forming apparatus must ensure that the length of the printing paper is not less than the distance between the feed roller 101 and the second conveyor roller 106 to reduce the probability of paper jams.

[0065] Taking two adjacent sheets of paper (sheet A and sheet B) as an example, assuming the lengths of sheets A and B are equal to the distance between the feed roller 101 and the second conveyor roller 106, the image forming apparatus detects, via sensor 105, that the beginning of sheet A has reached the second conveyor roller 106. It then controls the feed roller 101 to stop operating, while the second conveyor roller 106 and the first conveyor roller 104 provide power to continue conveying sheet A. After a preset conveying interval, the end of sheet A has typically left the feed roller 101. The image forming apparatus then controls the feed roller 101 to continue operating, conveying sheet B. The beginning of sheet B and the end of sheet A will maintain a certain distance (e.g., Y mm) to prevent paper jams at the second conveyor roller 106. If the length of the printed paper (printed paper C and printed paper D) is less than the distance between the paper feed roller 101 and the second conveyor roller 106, when the tail of printed paper C leaves the paper feed roller 101, the head of printed paper C has not yet reached the second conveyor roller 106. The paper feed roller 101 will continue to transport printed paper D until the head of printed paper C reaches the second conveyor roller 106 and then stops. Assuming that when the paper feed roller 101 is paused, the head of printed paper D has been transported X mm. After a preset transport interval, the paper feed roller 101 continues to transport printed paper D. The distance between printed paper C and printed paper D is (YX) mm, which may be less than the safety distance, causing paper jams at the second conveyor roller 106.

[0066] To address the aforementioned problems, embodiments of the present invention provide a method for controlling the paper transport interval in printing. This method can be applied to image forming equipment, such as... Figure 2 As shown, the method may include:

[0067] Step 201: Obtain the paper length of the printing paper and the first distance between the paper feed roller and the transfer roller.

[0068] In this embodiment of the invention, after receiving a print job, the image forming apparatus can obtain the paper length from the print parameters. The first distance between the feed roller and the transfer roller is a known quantity and can be stored in advance in the storage space of the image forming apparatus.

[0069] In one embodiment, the image forming apparatus is equipped with a paper feed sensor. During the paper feeding process, the image forming apparatus can determine the paper length using the paper feed sensor. Specifically, the image forming apparatus multiplies the time required for the paper to pass through the paper feed sensor by the operating speed of the paper feed sensor to obtain the paper length. The paper length detected by the paper feed sensor is more accurate. In some cases, the specifications of the paper in the tissue box differ from the printing parameters, and obtaining the paper length through the printing parameters may result in errors.

[0070] Step 202: Determine whether the printing paper meets the paper jam condition based on the relationship between the paper length and the first distance.

[0071] If the length of the printed paper is less than a first distance, the distance between two adjacent sheets of printed paper may be less than the safe distance. Therefore, a paper length less than the first distance can be considered a paper jam condition. If the image forming device determines that the paper length is less than the first distance, it determines that the printed paper meets the paper jam condition; if it determines that the paper length is greater than or equal to the first distance, it determines that the printed paper does not meet the paper jam condition.

[0072] In one embodiment, although a paper length shorter than a first distance may cause a paper jam, if the paper length is very close to the first distance, the distance between two adjacent sheets of paper is likely to be greater than a safe distance, preventing a paper jam. Therefore, the image forming device can also determine the difference between the paper length and the first distance. If the paper length is determined to be shorter than the first distance, and the absolute value of the difference is greater than a first threshold, then the paper is determined to meet the conditions for a paper jam; otherwise, the paper is determined not to meet the conditions for a paper jam. It can be understood that the difference between the paper length and the first distance determines X; the larger the absolute value of the difference, the larger X, and the smaller the distance (YX) between two adjacent sheets of paper. If (YX) is less than a safe distance, a paper jam is very likely to occur. The first threshold can be reasonably set based on actual conditions.

[0073] Step 203: If it is determined that the printing paper meets the paper jam condition, then extend the transfer interval between adjacent printing papers.

[0074] In this embodiment of the invention, the conveying interval is the time interval between the pause and restart of the self-feeding roller. When the image forming equipment detects that the end of the printing paper has reached the conveying roller, it controls the paper feeding roller to pause, and after the conveying interval, it controls the paper feeding roller to restart. If the image forming equipment determines that the printing paper meets the paper jam condition, it needs to extend the conveying interval to increase the distance between adjacent printing papers.

[0075] In one embodiment, the image forming apparatus determines a first transport interval based on the difference between the length of the printed paper and a first distance, and then replaces a preset original transport interval with the first transport interval. For example, if the original transport interval is 2 seconds, and the image forming apparatus determines a first transport interval of 3 seconds based on the difference between the paper length and the first distance, then the paper feed roller pauses operation and resumes operation after 3 seconds. The larger the absolute value of the difference between the paper length and the first distance, the larger the first transport interval calculated by the image forming apparatus.

[0076] Step 204: Transfer the printing paper based on the extended transfer interval.

[0077] Taking printing paper A and printing paper B as an example, if the distance between the beginning of printing paper B and the end of printing paper A is too close when the beginning of printing paper B reaches the conveyor roller, a paper jam may occur. In this embodiment of the invention, when the image forming device detects that the beginning of printing paper A has reached the conveyor roller, it controls the paper feeding roller to pause operation, while the conveyor roller continues to operate to transport printing paper A. After a first conveying interval, the paper feeding roller resumes operation to transport printing paper B. Because the first conveying interval is relatively large, the distance between the end of printing paper A and the beginning of printing paper B is relatively large, and a paper jam will not occur when the beginning of printing paper B reaches the conveyor roller.

[0078] In this embodiment of the invention, the image forming apparatus determines the transmission interval between printing papers by the relationship between the paper length and the distance between the paper feed roller and the conveying roller, which can effectively prevent paper jams during the transmission of printing papers.

[0079] Figure 3 This is a schematic diagram of a printing paper transport interval control device provided in an embodiment of the present invention. This device can be deployed in an image forming apparatus to implement the printing paper transport interval control method provided in this embodiment of the present invention, such as… Figure 3 As shown, the device may include: an acquisition module 310, a judgment module 320, a processing module 330, and a control module 340.

[0080] The acquisition module 310 is used to acquire the paper length of the printing paper and the first distance between the paper feed roller and the conveying roller.

[0081] The judgment module 320 is used to determine whether the printing paper meets the paper jam condition based on the relationship between the paper length and the first distance.

[0082] The processing module 330 is used to extend the transfer interval between adjacent printing papers if it is determined that the printing paper meets the paper jam condition.

[0083] Control module 340 is used to convey printing paper based on the extended conveying interval.

[0084] In one embodiment, the acquisition module 310 may obtain the paper length of the printing paper from the printing parameters of the job to be printed. Alternatively, the acquisition module 310 may obtain the transmission time required for the printing paper to pass through the paper feed sensor, and then determine the paper length based on the transmission time and the transmission speed of the paper feed sensor.

[0085] In one embodiment, the determination module 320 can determine whether the paper length is less than a first distance. If the paper length is determined to be less than the first distance, the printing paper is determined to meet the paper jam condition. If the paper length is determined to be greater than or equal to the first distance, the printing paper is determined to not meet the paper jam condition.

[0086] In one embodiment, the determination module 320 can determine the difference between the paper length and the first distance; if it is determined that the paper length is less than the first distance and the absolute value of the difference between the paper length and the first distance is greater than a first threshold, then it is determined that the printing paper meets the paper jam condition; otherwise, it is determined that the printing paper does not meet the paper jam condition.

[0087] In one embodiment, the processing module 330 can determine a first conveying interval based on the difference between the paper length and a first distance, and then replace the preset original conveying interval with the first conveying interval.

[0088] In one embodiment, when the control module 340 detects that the end of the currently conveyed printing paper has reached the conveying roller, it controls the paper feeding roller to pause operation; after the duration of the first conveying interval, it controls the paper feeding roller to resume operation to convey the next printing paper.
