To ensure machine quality and reduce rework and customer complaints, image forming devices are often tested to verify compliance with paper jam rates. Currently, this is done by manually sampling machines to verify compliance with paper jam rates.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings.

[0039] It should be understood that the embodiments described are only a portion of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0040] 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 the present invention. The singular forms "a", "an", "the" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0041] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0042] The present invention provides a paper jam processing method applied to an image forming device. Figure 1 The following is a block diagram of the structure of an image forming device. Figure 1 As shown, the image forming device includes a control unit, an engine unit, various detection units, and a display unit. The various detection units refer to sensors that detect whether a paper jam has occurred in the paper path and collect jam information when the image forming device is performing an operation. The engine unit is connected to all detection units to collect the jam information collected by each detection unit, classify and identify the collected jam information, generate and store various jam event descriptions and corresponding jam information. The control unit is connected to the engine unit to detect whether a user triggers a jam report event or triggers a jam report event at a specified period, and automatically collects the corresponding jam report data from the engine unit, generates a jam report, and displays it on the display unit. The display unit is connected to the engine unit and the control unit respectively, and is used to visually display the jam report and provide prompts to the user. The display unit can be the display screen of the image forming device or the display screen of a client connected to the image forming device, such as a PC. In this way, the engine unit and various detection units within the image forming device automatically count jam events and generate a jam event report for display to the user, eliminating the need for manual sampling, while improving the accuracy of jam rate identification and enhancing the user experience.

[0043] The paper jam processing method provided by the present invention is implemented by using an image forming device. Figure 2This is a flow chart of a paper jam handling method provided by one embodiment of the present invention, wherein each step is performed by an image forming device. The image forming device includes but is not limited to printers, scanners, copiers, fax machines, and multi-function printers (MFPs) that perform printing, copying, scanning, faxing, and other functions in a single device. Figure 2 As shown, the method includes:

[0044] Step 101: The engine unit obtains paper jam information detected by several detection units in the image forming device, wherein the paper jam information at least includes paper jam type information, medium length information, medium thickness information, paper jam occurrence time information, and on / off status information of the detection units.

[0045] Specifically, the image forming device is provided with various detection units distributed along the paper path corresponding to each job. When the detection unit detects that a paper jam has occurred in the image forming device, the detection unit sends the corresponding paper jam information to the engine unit, and the engine unit obtains the paper jam information. Optionally, the specific content of the paper jam information can be selected as needed or preset. Preferably, the paper jam information includes but is not limited to paper jam type information, medium length information, medium thickness information, paper jam occurrence time information, and the opening and closing status information of the detection unit. The paper jam type information is used to indicate the error information generated when a paper jam occurs in the current job and to provide data for the engine unit to analyze the cause of the paper jam, which includes a paper jam type code, a description of the occurrence of the paper jam, etc. The "medium" in the medium length information can be ordinary paper, thick paper, thin paper, film paper, envelope paper, label, document, etc., and the medium length information can be paper length information or paper width information. Therefore, in some devices that can only print on narrow paper, a preset paper width is used as a dividing point to distinguish between "large paper" (also known as long paper) and "small paper" (also known as narrow paper). Paper jams are more likely to occur when printing on media wider than the preset paper width. Therefore, paper jam length information is one of the factors that may cause paper jams. Media thickness information indicates the thickness of the media that caused the jam. Media thickness can be used to identify the media type, such as thick paper or thin paper. In other words, this media thickness information can also be used to indicate the media type, as described in the "media" example above. Furthermore, some image forming devices include a detection unit for detecting media thickness, such as using a weight sensor to detect media weight and identify the media thickness based on the media weight and the unit weight per page. Of course, in some embodiments, some image forming devices lack this detection unit for detecting media thickness. Alternatively, media size can be used to identify the current media thickness. Specifically, a pre-set correspondence between media size and media thickness can be used to determine the corresponding media thickness information by identifying the corresponding media size. The time of a paper jam includes, but is not limited to, the start time of the jam and the end time of the jam. The detection unit's opening and closing state information includes the detection unit's open state information and closed state information. In some embodiments, a paper jam may occur when the detection unit is actually closed when it should be in the open state. Therefore, the detection unit's opening and closing state information is also one of the factors causing the paper jam.

[0046] Prior to step 101, the engine unit is pre-set with the paper jam parameter information required for jam cause analysis. Alternatively, the engine unit can proactively acquire relevant jam information when a jam occurs. In step 101, the detection unit collects information on the paper path in real time, or it can collect information at intervals. The engine unit then acquires the relevant jam information when a jam is confirmed.

[0047] Next, after the engine unit obtains the paper jam information, it can be processed using the engine calculation algorithm configured in the engine unit. The engine calculation algorithm determines and populates the paper jam information according to preset rules to form paper jam description information corresponding to the paper jam information. The engine calculation algorithm can be preset or default, or it can be adjusted after using the image forming device for a period of time. The paper jam description information is used to describe the cause of the paper jam. Optionally, the paper jam description information can be configured to be displayed on the paper jam report so that managers can intuitively see the cause of the paper jam.

[0048] After the engine unit obtains the detected paper jam information, it uses the engine addition algorithm configured in the engine unit to determine whether the paper jam information is repeated. Specifically, the engine addition algorithm configured in the engine unit can be configured as follows:

[0049] Based on the received paper jam type information and paper jam occurrence time information, it is determined whether the detection unit has repeatedly detected the same paper jam information within a continuous preset time. This setting is intended to avoid storing repeated identical paper jam information, thereby not only saving storage space, but also avoiding invalid processing of the engine addition algorithm in the engine unit, thereby improving processing efficiency. Since the cover is continuously opened and closed when a paper jam occurs in the device and the cause of the paper jam has not been eliminated, it will also cause repeated detection of the same paper jam type information, that is, the same paper jam code (JAM ID) will still be displayed on the display screen. Based on this setting in the engine unit, the relevant paper jam information will not be stored repeatedly, that is, the same paper jam type information corresponds to different paper jam occurrence times before it is detected that the cause of the paper jam has not been eliminated. In other words, only the relevant paper jam information corresponding to the initial paper jam occurrence time is stored before it is detected that the cause of the paper jam has not been eliminated.

[0050] It should be noted that, in this embodiment, multiple times refers to 2 times or more, and the preset time setting needs to ensure that the number of detections is at least 2 times.

[0051] Specifically, in the same job, such as a print job, if the same paper jam code information is detected repeatedly at least twice in a row, only the paper jam information corresponding to the initial moment of the paper jam is recorded and the corresponding paper jam description information is stored. That is, if the above determination result is no, the engine unit stores the paper jam information detected by the detection unit and the paper jam description information corresponding to the paper jam information; if the above determination result is yes, the engine unit only stores the same paper jam information detected repeatedly once and the corresponding paper jam description information. In a specific implementation, the engine unit can store the paper jam information and the paper jam description information corresponding to the paper jam information in the form of a paper jam table in a non-volatile memory (NVM), also known as a non-volatile memory. In some embodiments, the non-volatile memory can be a Flash memory.

[0052] Furthermore, before the engine unit stores the paper jam information detected by the detection unit and the paper jam description information corresponding to the paper jam information, the engine unit needs to determine whether the paper jam type information and the paper jam description information already exist in the paper jam table;

[0053] If so, only the number of paper jams in the paper jam table is updated. In this way, there is no need to repeatedly update the same paper jam type information and the paper jam description information corresponding to the paper jam information, which is beneficial for the engine unit to integrate the paper jam information.

[0054] If not, the paper jam information and paper jam description information sent by the control unit are obtained, stored in the paper jam table, and the paper jam count information is updated. In other words, if the paper jam information and the corresponding paper jam description information are not available in the paper jam table within the engine unit, they are stored and the paper jam count information is updated. The paper jam count information may include the number of paper jams, the number of paper jams that have occurred, and the time of the last paper jam.

[0055] Furthermore, the engine addition algorithm program in the present application pre-configures the filled area and non-filled area (i.e., fixed area) in the paper jam description information. The filled area is used to indicate the value of the paper jam information where the paper jam occurred, such as the paper jam code value jam01, jam02, jam20, etc. The fixed area is used to indicate the paper jam description text, i.e., the parameter field involved in the cause of the paper jam, such as "occurred when the printing paper width is", "occurred when printing thin paper is", "occurred when printing thick paper is". In this way, modular management can be achieved without the need for manual statistics, and it also speeds up the efficiency of subsequent report generation. Furthermore, in some implementations, the filled area can be further divided into a displayed filled area and an implicit filled area. The displayed filled area refers to the information value that can be directly obtained without processing, while the implicit filled area refers to the information value that needs to be processed, such as identification processing, comparison processing, and filtering processing. For example, the paper jam description information display is: jam01 occurs when the printing paper width is ≤100mm. The fill areas are "jam01 (i.e., the paper jam code value)", "≤ (i.e., the result of the comparison with the preset paper jam threshold)", and "100mm (i.e., the preset paper jam threshold)". "jam01 (i.e., the paper jam code value)" and "100mm (i.e., the preset paper jam threshold)" are explicit fill areas, while "≤ (i.e., the result of the comparison with the preset paper jam threshold)" is implicit. The non-fill area is "occurs within the paper width".

[0056] Therefore, the engine addition algorithm program also configures a corresponding processing program for the implicit fill area based on the actual paper jam description information. As shown in the example above, in this embodiment, the engine addition algorithm program also includes various comparison programs, such as a printing paper width comparison program and a printing thickness comparison program. In the printing paper width comparison program, the media length information in the paper jam information is compared with a pre-set media length threshold to obtain a size comparison result, and the size comparison result value is then filled into the corresponding fill area. Of course, the comparison program in this embodiment can be executed by a comparator or a software program.

[0057] Step S102: When the control unit detects a paper jam report event, it sends a report request command to the engine unit, wherein the report request command carries target parameter information and target model identification information to be collected; the target parameter information includes at least paper jam type information, medium length information, medium thickness information, and number of paper jams information.

[0058] In an embodiment of the present application, parameter information stored in the engine unit is pre-set in the image forming device. The parameter information is the initial information obtained by the engine unit from each detection unit, and also includes the processed initial information. Further, the parameter number information at least includes the target parameter information that needs to be collected by the controller (such as data firmware, etc.) to generate a report. Among them, the parameter information includes but is not limited to device information (such as device model, device serial number, device parameter number, i.e., device parameter ID, total number of pages that can be printed by the device), job paper width information, paper jam type code, paper jam parameter statistics time, report time (time to generate the report, time to display on the terminal, etc.), power-on time (such as the first power-on time of the device), each sensor detection information (paper jam detection information, switch status information, paper jam time), whether the device is saved when it loses power, and other information.

[0059] Furthermore, the target parameter information is used to indicate data required to generate a paper jam report. In some embodiments, the target parameter information may be derived from parameter information stored in the engine unit or from parameter information processed from acquired parameter information. The target parameter information includes at least information on paper jam type, media length, media thickness, and number of paper jams.

[0060] When the control unit detects a paper jam report event in step 102, it sends a report request command to the engine unit. The paper jam report event is used to indicate whether the generation of a paper jam report is triggered. If the paper jam report event is not triggered, there is no need to generate a paper jam report. In this embodiment, the paper jam report event includes but is not limited to detecting that the "User Improvement Plan" option is checked, detecting that the image forming device is turned on or switched from sleep mode to standby mode, detecting that the "Paper Jam Information Feedback" option is checked, detecting that a configuration page print job is triggered, and detecting that a maintenance page print job is triggered. In other words, when a user or maintenance personnel needs to obtain the paper jam situation and gain an in-depth understanding of the cause of the paper jam, they can choose to trigger a paper jam report event by checking the "User Improvement Plan" option.

[0061] For example, Figure 3 As shown, the control unit checks whether a paper jam report event has been triggered, such as whether the "User Improvement Program" option is checked. If not, it checks whether the "Paper Jam Information Feedback" option is checked. If so, a paper jam report event is triggered and a report request command is issued. If the "Paper Jam Information Feedback" option is not checked, it determines whether a configuration page print job has been detected. If so, a paper jam report event is triggered. If not, it determines whether a maintenance page print job has been detected. If the "Paper Jam Information Feedback" option is checked, a paper jam report event is triggered. If a maintenance page print job is detected, a paper jam report event is triggered.

[0062] Optionally, the medium length information in the target parameter information can be divided into greater than 182 mm and less than or equal to 182 mm. Optionally, in other embodiments, the medium length information is processed in segments, and the medium length information is divided into the following four dimensions: less than 148 mm, greater than or equal to 148 mm and less than 182 mm, greater than or equal to 182 mm and less than 250 mm, and greater than or equal to 250 mm. Among them, the medium is too thick or too thin and it will easily cause paper jams, so the medium thickness information is also one of the possible causes of paper jams. The medium thickness information can be divided into two categories. One is that the medium thickness information is less than 70 g / m 2 , the media thickness information is greater than 100g / m 2 In other embodiments, the media thickness information is divided into the following four dimensions: less than 70g / m 2 , greater than or equal to 70g / m 2 And less than 100g / m 2 , greater than or equal to 100g / m 2 And less than 150g / m 2 , greater than 150g / m 2 .

[0063] Optionally, the target parameter information may also include device information or whether the device is saved after power failure. Device information includes, but is not limited to, the device model, device serial number, device parameter number, and device parameter storage value range. The device parameter storage value range can be set to 0 to 99999999. Jam type information and device parameter numbers can be numbered with numbers or letters, for example, JAM CODE 01 and EC-10000-001.

[0064] Step S103: The engine unit responds to the report request command, obtains target data corresponding to the target parameter information according to the target model identification information, and sends the target data to the control unit.

[0065] In an embodiment of the present application, the target model identification information can be used to identify the corresponding device model of each image forming device, and target parameter information corresponding to the device model is obtained based on the device model. The target data can be a paper jam report element presented to a user or maintenance personnel. In other words, the engine unit obtains the required content of the paper jam report and sends it to the control unit.

[0066] Among them, the target data may include but is not limited to the following aspects: device model, device parameter number, paper jam type information, media length information, media thickness information, paper jam number information, total number of printed pages, paper jam detection information, whether power off is saved, report generation time and the first power-on time of the device, etc.

[0067] Step S104 : The control unit processes the target data, generates a paper jam report, and displays the report on the image forming device and / or sends the report to a client or server connected to the image forming device.

[0068] Specifically, the control unit integrates target data into a paper jam report in a preset report format according to established requirements, and optionally displays the paper jam report on a display unit of the image forming device or sends it to a client or server connected to the image forming device.

[0069] Optionally, the content of the paper jam report can be expanded or deleted based on actual conditions. Optionally, if the total number of pages in a single print run exceeds 3,000, an email can be immediately sent to the client. The control unit can also be set to send paper jam reports to the client or server at regular intervals, such as weekly or monthly.

[0070] It can also be set on the control unit: if the total number of paper jams of a device exceeds a certain threshold, the paper jam situation of this device will no longer be counted.

[0071] Furthermore, the control unit processes the target data and generates a paper jam report, including:

[0072] S1041, obtaining a preset screening condition for the paper jam report;

[0073] In practice, a preset filter condition can be set to only count paper jams on a device if the total number of paper jams reaches a preset value. For example, if a device has not experienced 5 or 10 paper jams, the corresponding paper jam information will not be counted and will not appear in the paper jam report. This can be achieved by setting filter conditions for paper jam reports, especially for low-end devices or in applications where only one page of report is required.

[0074] S1042, filtering out report data that meets preset filtering conditions from the target data;

[0075] In the specific implementation, when the total number of paper jams of the device reaches a preset value, screening is performed, where the target data includes device model, device parameter number, paper jam type information, media length information, media thickness information, number of paper jams information, total number of printed pages, report generation time and first power-on time; the report data comes from the target data.

[0076] S1043: Process the report data according to a predetermined report format to generate a paper jam report.

[0077] Specifically, the device model, device parameter number, and total number of printed pages in the paper jam report data can be stored in the engine unit. Information on paper jam type, media length, media thickness, and number of paper jams can be retrieved in real time based on the device parameter number. The report generation time and the first power-on time should be determined based on the system clock or network time. If the time accuracy cannot be guaranteed, these two items can be ignored.

[0078] The optional first power-on time is divided into two categories: the first time for market devices (i.e., devices currently in circulation) is the first time the device is powered on after purchase; the second time for devices under development is the first time a prototype device is powered on after arriving at a testing area or department. The device model corresponding to each device is typically provided on the configuration or maintenance page. Whether it's a market device or a prototype, maintenance personnel and R&D personnel can intuitively see paper jam conditions for that device.

[0079] Specifically, each step is performed by an image forming device, including but not limited to printers, scanners, copiers, fax machines, and multi-function printers (MFPs) that perform printing, copying, scanning, faxing, and other functions in a single device.

[0080] Figure 31 illustrates a structural block diagram of an image forming device according to an embodiment of the present invention. Figure 3 As shown, the image forming device includes a control unit, an engine unit, and various detection units and a display unit. Among them, the various detection units refer to various sensors that detect whether a paper jam occurs in the paper path and collect paper jam information when the image forming device performs a job. The engine unit is connected to all the detection units to collect the paper jam information collected by each detection unit, and classifies and identifies the collected paper jam information, generates various event descriptions of paper jams and corresponding paper jam information, and stores them. The control unit is connected to the engine unit to detect whether the user triggers a paper jam report event or triggers a paper jam report event at a specified period, so as to automatically collect corresponding paper jam report data from the engine unit, generate a paper jam report, and display it on the display unit. The display unit is connected to the engine unit and the control unit respectively, and is used to visually display the paper jam report and prompt the user. The display unit includes a display screen of the image forming device, and can also be a display screen of a client connected to the image forming device, such as a PC.

[0081] The engine unit includes a non-volatile memory, which includes a paper jam table. The engine unit stores the paper jam information detected by the detection unit and the paper jam description information corresponding to the paper jam information.

[0082] Figure 4 Schematically shows each detection unit in the image forming device. Figure 4 As shown in the figure, as an example of various detection units within an image forming apparatus, the sensors include an input sensor for detecting paper input, an output sensor for detecting paper output, and a detection sensor. The paper feed direction is sequentially divided into the input sensor, the detection sensor, and the output sensor. Each sensor is used to detect the position and direction of the media. When a paper jam is detected by each sensor, the jam information is transmitted to the engine unit.

[0086] Figure 5 The structure of the paper jam handling system is shown schematically. Figure 5 As shown, the paper jam handling system includes: an image forming device, and a client and a server respectively connected to the image forming device, wherein the image forming device is the image forming device described above. The image forming device is configured to generate a paper jam report based on a paper jam event and send it to the client or server.

[0087] It can be understood that in the embodiment of the present invention, various detection sensors on a paper path of an image forming device detect whether a paper jam has occurred. When a paper jam is detected, a paper jam event is triggered, and information corresponding to the paper jam is sent to an engine unit. After obtaining the information, the engine unit generates paper jam description information corresponding to the paper jam information using an engine addition algorithm set in the engine unit according to preset rules. When the paper jam event is triggered and conditions are met, a paper jam report event is triggered. When the control unit detects the paper jam report event, it sends a report request command to the engine unit. The engine unit receives and responds to the report request command, and simultaneously obtains target data corresponding to target parameter information based on target model identification information, and sends the target data to the control unit. The target model identification information is the unique and specific model corresponding to the target device. The control unit processes the target data, generates a paper jam report according to a preset report format, and displays it on the image forming device and / or sends it to a client or server connected to the image forming device. The above-mentioned paper jam handling method can avoid inaccurate paper jam cause data caused by inaccurate manual sampling and limited sampling, which makes it difficult to deeply understand the cause of the paper jam.
