Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of image forming, and particularly relates to an image forming control method, an image forming device and a self-service terminal device.

BACKGROUND

[0002] Self-service terminals are used more and more widely in people's life, and people's life becomes more and more convenient. People can handle all kinds of things through self-service terminals. An image forming device is placed in the self-service terminal for printing an image on a print medium to form an output. An outlet of the image forming device is connected with an outlet of the self-service terminal. The output is discharged out of the self-service terminal, and the user can take the output. However, the self-service terminal is a closed machine. The user can only touch the discharged paper and an operation panel. If the size of the output along a paper discharge direction is less than the distance from the outlet of the image forming device to the outlet of the self-service terminal, the output cannot reach the outlet of the self-service terminal, and the user cannot take the output. If the distance from the outlet of the image forming device to the outlet of the self-service terminal is shortened, and the size of the output along the paper discharge direction is greater than the distance from the outlet of the image forming device to the outlet of the self-service terminal, the output can directly slide from the outlet of the self-service terminal to the ground, and the user's demand cannot be met.

[0003] Therefore, there is an urgent need for a scheme to make the output of the image forming device be discharged properly, and meet the user's demand of taking the output.

Detailed Implementation Methods

[0034] 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.

[0035] 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.

[0036] like Figure 1 , Figure 2 The image forming apparatus shown includes a housing 11, a front cover 103, and a paper outlet 104. The image forming apparatus 10 includes a frame 12 disposed within the housing 11. Various functional modules are installed on the frame 12, including a paper storage unit 13 located at the bottom of the frame 12 for storing paper to be printed, an image forming section 14 located in the middle of the frame 12 for forming images on the paper, and a paper discharge mechanism 15 located at the top of the frame 12 for discharging paper.

[0037] A paper conveying path 16 is formed inside the frame 12 for conveying paper. The paper is taken out of the paper storage unit 13 by a paper feeding mechanism 131 located above the paper storage unit 13, and is conveyed to the image forming section 14. After an image is formed by the image forming section 14, the paper is conveyed to the fixing mechanism 17, which fixes the image on the paper by high pressure and high heat. After being processed by the fixing mechanism 17, the paper is conveyed to the paper discharge mechanism 15, which has a paper discharge path 151 in communication with the paper conveying path 16. The paper on which the printing job is completed is placed in the paper discharge path 151. When the paper needs to be printed on both sides, the paper is conveyed in reverse into the inside of the image forming apparatus 10 before it has completely entered the paper discharge path 151, and enters the double-side printing path 18 from the image forming section 14, enters the conveying path 16 from the double-side printing path 18, and enters the image forming section 14 again, and is finally discharged from the paper discharge mechanism 15. The driving of the various functional modules and the conveying of the paper are driven by a main driving source (not shown), such as a driving motor, provided inside the image forming apparatus.

[0038] To facilitate user operation, the front cover 103, the paper discharge path 151, and the paper storage unit 13 are all provided on the front face of the image forming apparatus 10. When the developer inside the image forming section 14 is insufficient, the user can open the front cover 103 from the front face, and then take out the image forming section 14 from the frame 12 for replacement. When the number of papers in the paper storage unit 13 is insufficient, the user can pull out the paper storage unit 13 from the front face, and then put in papers, and then insert the paper storage unit 13 into the image forming apparatus 10. The front end of the paper can protrude from the paper outlet 104 through the paper discharge path 151, and the user can take out the paper from the front face of the image forming apparatus 10.

[0039] Specifically, a first opening 101 is provided at the lower part of the front face of the image forming apparatus 10, and the paper storage unit 13, which is configured in a box shape, can be detached from or installed in the image forming apparatus 10 through the first opening 101. The paper storage unit 13 is provided with a handle to facilitate user pulling. A second opening 102 is provided at the middle part of the front face of the image forming apparatus 10, through which the user can install or detach the image forming section 14 from the image forming apparatus 10 to facilitate replacement of the image forming section 14. Further, a front cover 103 is provided on the front face of the image forming apparatus 10 to shield or open the second opening 102. A paper outlet 104 is provided at the upper part of the front face of the image forming apparatus 10, which is in communication with the paper discharge path 151. The front end of the paper can protrude from the front face of the image forming apparatus 10 through the paper outlet 104, and the user can take out the paper from the front face of the image forming apparatus 10.

[0040] Figure 2As shown, the left side is the back of the image forming device 10, and the right side is the front of the image forming device 10, i.e. the side facing the customer operation. The paper conveying process in the conveying channel 16 is as follows: the paper output from the paper storage unit 13 is conveyed from the front to the back of the image forming device 10 by the paper feeding mechanism 131 and the first conveying wheel 161, enters the fixing mechanism 17 after passing through the image forming unit 14, and then is conveyed from the back to the front of the image forming device 10 by the second conveying wheel 162, and finally is discharged through the first discharge roller 152, enters the paper discharge channel 151.

[0041] The image forming device can include an inkjet printer, a laser printer, an LED (Light Emitting Diode) printer, a fax machine, a copier, a scanner, or a multifunctional peripheral (MFP), etc., without limitation, and an example of the image forming device is the image forming device 10 described above.

[0042] As shown in the accompanying drawings, Figure 3 The image forming device 10 described above can be installed in a self-service terminal device 20, which has a housing 21. Generally, the housing 21 can be provided with an operation panel 22, a display screen 23, a discharge port 24, etc. according to the needs of the actual application scene, and the control system 25 controls each module and the image forming device 10. The user operates from the outside of the self-service terminal device 20, and the paper outlet 104 of the image forming device 10 corresponds to the discharge port 24 of the housing 21. The paper is output from the paper discharge channel 151, and the front end of the paper protrudes from the discharge port 24. The user takes the paper from the discharge port 24.

[0043] In order to enable the paper to be smoothly output through the paper discharge channel 151, the paper outlet and the discharge port can be accurately matched. The paper discharge mechanism provided by the present application is described in detail below.

[0044] As shown in the accompanying drawings, Figure 4 , 5The figures shown are a top view and a side view of the paper discharge mechanism 15. From left to right, the paper discharge channel 151 is in the paper transport direction. A first paper tray 153 and a second paper tray 154 are arranged along this direction. A swingable paper conveyor 155 is arranged between the first paper tray 153 and the second paper tray 154. In the paper transport direction, a pair of first discharge rollers 152 are arranged upstream of the first paper tray 153. The paper conveyor 155 includes a swing frame 155a and a conveying wheel 155b rotatably mounted on the swing frame 155a. A drive shaft 155d is provided on the swing frame 155a. The drive shaft 155d is connected to the main drive source in the image forming apparatus 10 to drive the conveying wheel 155b to rotate. In the paper conveying direction, the drive shaft 155d is located downstream of the conveying wheel 155b to avoid excessive pressure on the swing frame 155a during operation. The second paper tray 154 is closer to the paper outlet 104 of the image forming apparatus 10 than the first paper tray 153. The first paper tray 153 carries the output components from the conveying channel 16 of the image forming apparatus 10. Specifically, the first paper tray 153 carrying the output components from the conveying channel 16 means that at least part of the output components from the conveying channel 16 are in contact with the first paper tray 153; this is not limited here. The second paper tray 154 carries the output components that have passed through the first paper tray 153, including those carried by the first paper tray 153.

[0045] The swing frame 155a can swing around the drive shaft 155d, so that the conveying wheel 155b can contact or separate from the second discharge roller 156 installed between the first paper tray 153 and the second paper tray 154. When the conveying wheel 155b contacts the second discharge roller 156, it can clamp and convey the paper. Therefore, by selectively swinging the paper conveyor 155, it can convey paper of different sizes, making it convenient for users to take away the paper.

[0046] Furthermore, when the paper conveyor 155 is in the paper conveying state, the conveying wheel 155b contacts the second row of paper rollers 156, and the output component of the image forming apparatus carried by the first row of paper trays 153 is conveyed to the second row of paper trays 154. When the paper conveyor 155 is in the non-paper conveying state, the conveying wheel 155b separates from the second row of paper rollers 156, and the output component of the conveying channel 16 is directly conveyed to the first row of paper trays 153.

[0047] Need to explain, in the embodiment of the application, the paper conveying can also be directly performed by the conveying wheel 155b, and the second paper discharge roller 156 does not need to be arranged, that is, when the paper conveying device 155 is in the paper conveying state, the conveying wheel 155b conveys the output part passing through the first paper discharge tray 153 to the second paper discharge tray 154, and when the paper conveying device 155 is in the non-paper conveying state, the conveying wheel 155b does not perform the conveying action of the output part.

[0048] Specifically, when the paper discharged by the image forming device 10 is long enough, so that the user can take out the paper from the discharge outlet 24 of the self-service terminal device 20 after the paper is discharged, the paper conveying device 155 is driven to swing upward, and the conveying wheel 155b is separated from the second discharge roller 156. Because the paper is long enough, when the paper is discharged from the first discharge roller 152, the tail end of the paper falls on the first paper discharge tray 153, and the front end can still extend from the discharge outlet 24, and the user can take the paper out of the self-service terminal device.

[0049] However, if the paper is short, when the paper is discharged from the first discharge roller 152, the front end of the paper cannot still extend from the discharge outlet 24, the paper conveying device 155 will be driven to swing downward, so that the conveying wheel 155b is in contact with the second discharge roller 156, and the conveying wheel 155b and the second discharge roller 156 further convey the paper to the second paper discharge tray 154, at this time, the front end of the paper can extend from the discharge outlet 24, and the user can take the paper out of the self-service terminal device.

[0050] The paper conveying device 155 is connected with the main driving source in the main body of the image forming device 10 to obtain driving force, and for this purpose, the application is provided with a pushing mechanism 157 for driving the swing frame 155a to swing, so as to selectively make the conveying wheel 155b in contact with or separated from the second discharge roller 156.

[0051] The paper conveying device 155 can be driven by a separate driving source, such as a driving motor, or can be connected with the main driving source in the main body of the image forming device 10 to obtain driving force, and for this purpose, the application is provided with a pushing mechanism 157 for driving the swing frame 155a to swing, so as to selectively make the conveying wheel 155b in contact with or separated from the second discharge roller 156.

[0052] As Figures 4-6As shown, the pushing mechanism 157 of the present application is provided with a swing arm 157a for pushing the swing frame 155a to swing, the swing frame 155a can be provided with a protrusion for cooperating with the swing arm 157a, and a cam 157b is further provided for pushing the swing arm 157a to swing, the swing arm 157a has a rotating shaft, and the two ends of the rotating shaft are provided with cantilever arms respectively contacting the cam 157b and the swing frame 155a, so as to transmit the rotation of the cam 157b to the swing frame 155a. In order to realize the intermittent swing of the driving cam 157b, the pushing mechanism 157 of the present application adopts the mode of double toothless gears cooperating with locking components, and the locking components can adopt an electromagnetic solenoid 157g.

[0053] Specifically, the above-mentioned double toothless gears include a first toothless gear 157c and a second toothless gear 157d, and the outer ring gear teeth have a toothless part T, which cooperates with a driving gear 157e from the body, further, according to the rotating distance of the cam 157b, two toothless parts T are respectively arranged on the first toothless gear 157c and the second toothless gear 157d, and the two toothless parts T are symmetrically arranged relative to the gear shaft. The above-mentioned cam 157b is arranged on the first toothless gear 157c and rotates together with it, and the cam 157b can also be integrally formed with the first toothless gear 157c. The outer end surface of the second toothless gear 157d is provided with a buckle 157f, which cooperates with a hook 157h on the electromagnetic solenoid 157g, and the position of the buckle 157f coincides with the position of the above-mentioned toothless part T, further, two buckles 157f symmetrically arranged relative to the gear shaft can be provided. A pushing spring 157i is further arranged between the first toothless gear 157c and the second toothless gear 157d to provide a pushing force to enable the two toothless gears to rotate relative to each other.

[0054] The working process of the pushing mechanism 157 of the present application is further described below.

[0055] When the cam 157b is in a static state, the toothless part T of the first toothless gear 157c and the second toothless gear 157d is opposite to the driving gear 157e, and the hook 157h on the electromagnetic solenoid 157g is clamped on the buckle 157f, preventing the second toothless gear 157d from rotating, the first toothless gear 157c and the cam 157b are pressed by the swing frame 155a and also cannot rotate, but the pushing spring 157i is in a state of accumulating elastic energy under the combined action force of the first toothless gear 157c and the second toothless gear 157d.

[0056] When the swing arm 155a needs to swing, the solenoid 157g is activated, separating the hook 157h from the latch 157f. The second toothed gear 157d rotates under the thrust of the push spring 157i, causing the toothed part of the second toothed gear 157d to mesh with the drive gear 157e. The drive gear 157e drives the second toothed gear 157d to rotate, which in turn drives the first toothed gear 157c to rotate, thereby driving the cam 157b to rotate. When the cam 157b contacts the swing arm 157a, it will cause the swing arm 157a to rise; conversely, when the cam 157b separates from the swing arm 157a, the swing arm 157a will descend due to its own weight or elastic force.

[0057] When the second toothed gear 157d rotates, the electromagnetic solenoid 157g immediately closes, causing the hook 157h to contact the second toothed gear 157d. After the second toothed gear 157d rotates half a turn, the hook 157h will engage with the buckle 157f again, and the cam 157b will contact or separate from the swing arm 157a again.

[0058] like Figure 2 As shown, in order to detect the position of the swing frame 155a, a first sensor 151a is set in the paper discharge channel 151. When the image forming device 10 is started, the system will activate the first sensor 151a to detect the position of the swing frame 155a. The first sensor 151a sends the detected signal to the image forming device 10. In conjunction with the printing command issued by the user, which includes the printing paper size, it is determined whether the electromagnetic solenoid 157g needs to be activated to change the position of the swing frame 155a.

[0059] Specifically, when the first sensor 151a is triggered, the swing frame 155a is in the raised position, and the conveying wheel 155b is separated from the second discharge roller 156. If the user's print command includes a longer paper size, the solenoid 157g does not need to be activated. Once the internal functional modules of the image forming device 10 meet the printing conditions, the paper is fed directly for printing. However, if the user's print command includes a smaller paper size, the paper cannot be conveyed to the discharge port 24. Therefore, the system activates the solenoid 157g, causing the cam 157b to rotate downwards, and the swing frame 155a swings downwards under its own weight or elastic force.

[0060] When the first sensor 151a is not triggered, the swing frame 155a is in the lowered position, if the print paper size contained in the print command issued by the user is the longer size paper, the solenoid 157g is activated to rotate the cam 157b to the upper position, the swing frame 155a is lifted by the cam 157b, the conveying wheel 155b is separated from the second ejection roller 156, when the first sensor 151a detects the swing frame 155a, the image forming device enters the print mode, when the internal function module meets the print condition, the direct feeding printing is performed. If the print paper size contained in the print command issued by the user is the smaller size paper, the solenoid 157g is not activated, the image forming device can directly enter the print mode.

[0061] The above case is that according to the print command issued by the user, the state of the swing frame 155a is detected by the first sensor 151a, in the case that the swing frame 155a does not meet the paper ejection condition, the system activates the solenoid 157g, changes the position of the swing frame 155a by the swing of the missing tooth gear, the cam 157b and the swing arm 157a, so that the swing frame 155a meets the paper ejection condition. If the detection result of the first sensor 151a does not change after a predetermined time, the system will activate the solenoid 157g again, if the detection result of the first sensor 151a does not change after a predetermined time, the system will prompt the user that the swing of the swing frame 155a is abnormal, and the printing operation is suspended, the user needs to detect whether the solenoid 157g is faulty, whether the swing frame 155a and the cam 157b and the swing arm 157a are damaged.

[0062] In another case, the print paper size contained in the print command issued by the user is consistent with the paper size corresponding to the position of the swing frame 155a, but due to human error, the paper actually placed in the image forming device 10 is not the paper size required by the print command, and the general image forming device 10 cannot detect the size of the paper in advance, so it cannot remind the user of the paper type mismatch before printing starts. Then the image forming device 10 will perform the following operation.

[0063] After the user issues a print command, the paper is picked up by the paper feed mechanism 131 and enters the conveying channel 16, and then passes through the fourth sensor S4 arranged in the conveying channel 16. The fourth sensor S4 is pressed and activated by the paper, so that the system knows the position passed by the paper. Further, the system calculates the time from the activation to the deactivation of the fourth sensor S4, and according to the conveying speed of the paper, the actual length of the paper in the paper conveying direction can be obtained. If the actual length of the paper is consistent with the print paper size in the print command, normal printing is performed. If not, the system immediately switches the position of the swing frame 155a, so that the first output based on the print command is normally discharged, for example, when the print paper size contained in the print command is A4 size, and the actual size of the paper in the conveying channel 16 is A5 size. The swing frame 155a needs to be in the lowered position, so that the conveying wheel 155b is in contact with the second discharge roller 156, and the first output based on the print command can be discharged to the second paper discharge tray 154, but not to the first paper discharge tray 153, so that the user cannot take it out. The output will remain in the image forming device 10, which may cause information leakage. If the print paper size of the print job is A5 size, and the actual paper size is A4 size, the swing frame 155a needs to be in the raised position, so that the paper is discharged to the first paper discharge tray 153, but not to the outside of the self-service terminal device 20. Of course, after the first paper is discharged, the image forming device 10 outputs prompt information indicating that the paper size information contained in the print command does not match the actual paper size in the conveying channel 16 of the image forming device 10, and stops printing. The user needs to adjust the paper.

[0064] Further, in order to improve the quality of paper imaging and avoid paper tilt when entering the image forming part 14, a pair of correction rollers 163 is arranged in the conveying channel 16 at a position upstream of the paper conveying direction of the image forming part 14, and a fifth sensor S5 is arranged upstream of the correction rollers 163. The working principle of the fifth sensor S5 and the correction rollers 163 is that when the paper is output from the paper storage unit 13, the first conveying wheel 161 clamps and conveys the paper to press and trigger the fifth sensor S5. At this time, the correction rollers 163 are in a static state. Due to the continuous conveying of the first conveying wheel 161, the front end of the paper abuts against the correction rollers 163, so that the front end of the paper is axially parallel to the correction rollers 163, thereby correcting the tilt of the paper. When the fifth sensor S5 is triggered for more than a predetermined time, the system starts the rotation of the correction rollers 163, and the correction rollers 163 clamp and continue to convey the paper to move in the conveying channel 16.

[0065] It should be noted that in the above scheme, the first output generated based on the print command can be directly discharged to the second paper tray 154, or the paper tray of the first output can be directly determined based on the actual paper size in the conveying channel 16 of the image forming device 10. The sensor detects the position of the swing frame 155a to accurately determine the position of the swing frame 155a, and changes the position of the swing frame 155a in time according to the size of the paper to be printed, so as to avoid inconvenience to the user.

[0066] Further, in order to detect the position of the paper in the paper discharge channel 151, a second sensor S2 and a third sensor S3 are arranged in the paper discharge channel 151. When the paper is conveyed in the paper discharge channel 151, it will push the second and third sensors, and the sensors will be activated, and then a signal will be sent to the image forming device 10.

[0067] The second sensor S2 is located upstream of the paper discharge direction of the first discharge roller 152. When the activation time of the second sensor S2 exceeds the predetermined time, the system will prompt the user that the paper is jammed in the paper discharge channel 151 and needs to be removed. The user can remove the paper by opening the guide cover plate above the paper discharge channel 151. However, when the image forming device 10 needs to perform double-sided printing, the time when the second sensor S2 is pressed by the paper will exceed the predetermined time. However, since it is in double-sided printing mode, the triggering time of the second sensor S2 is set to be longer, so the image forming device will not prompt the jamming condition. Further, in order to prevent the paper from retreating to the inside of the image forming device 10 when pressing the second sensor S2, increasing the friction, causing damage to the second sensor S2 or scratching the paper, a guide wheel can be arranged at the end of the second sensor S2, so that the friction between the paper and the second sensor S2 becomes rolling friction.

[0068] The third sensor S3 is arranged on the second paper tray 154. When the paper is discharged from the first discharge roller 152, it will press on the third sensor S3. The system determines whether there is paper on the second paper tray 154 through the signal of the third sensor S3. When a print job is completed or before the next print job starts, the system will prompt the user to remove the paper.

[0069] In the double-sided printing mode, in order to control the time of paper reversal, a sixth sensor S6 is arranged downstream of the paper discharge direction of the fixing mechanism 17. When the paper passes through the sixth sensor S6, the sixth sensor S6 is triggered to inform the system that the paper has been output from the fixing mechanism 17. After the paper leaves the sixth sensor S6 for a predetermined time, the driving mechanism of the image forming device 10 is controlled to reverse rotation. When the sixth sensor S6 is triggered for more than a predetermined time, the system will issue a jam signal to prompt the user to remove the jam.

[0070] Preferably, in order to ensure that the swing frame 155a can swing downwardly and provide a certain pressure so that the conveying wheels 155b and the second discharge roller 156 can clamp and convey the paper, a pressing spring 155c is arranged in the paper discharge channel 151 to provide a continuous downward pressing force to the swing frame 155a. A torsion spring 157j or a spring can also be arranged on the swing arm 157a to apply a downward pressure to the swing arm 157a, so that the swing arm 157a can normally press on the cam 157b and can keep the positions of the cam 157b and the first missing tooth gear 157c, and when the electromagnetic solenoid 157g is activated, the first missing tooth gear 157c and the second missing tooth gear 157d can normally rotate relative to each other, thereby ensuring that the swing frame 155a can normally switch positions.

[0071] The image forming apparatus 10 of the present application outputs a blank paper when it is powered on and before it receives a print command from a user. When the paper passes through the fourth sensor S4, the fourth sensor S4 is triggered, and the image forming apparatus 10 knows that there is paper to be conveyed. Then the system activates the first sensor 151a to detect the position of the swing frame 155a. If the swing frame 155a is in the lowered position, the electromagnetic solenoid 157g is not activated, and the paper is normally discharged. If the swing frame 155a is in the raised position, the system activates the electromagnetic solenoid 157g to switch the position of the swing frame 155a, so that the conveying wheels 155b and the second discharge roller 156 can clamp and convey the paper.

[0072] The image forming apparatus 10 of the present application is provided with a paper storage unit 13 for placing paper. In addition, according to the actual needs of a user, an additional paper storage unit 13a can be added below the image forming apparatus 10, as shown in the attached Figure 7 The paper storage unit 13a is a detachable accessory of the image forming apparatus 10 and can be electrically connected and communicate with the image forming apparatus 10 through a connector. A driving motor can be separately arranged or connected to the image forming apparatus 10 through a gear to obtain driving force. A paper feeding mechanism is arranged in the paper storage unit 13a to feed paper. The paper path in the paper storage unit 13a is connected to the paper conveying channel 16 of the image forming apparatus 10. The paper output from the paper storage unit 13a enters the image forming apparatus 10, sequentially passes through the image forming unit 14 and the fixing mechanism 17 for imaging and fixing operations, and is finally output to the paper discharge mechanism 15.

[0073] Different paper storage units can store paper of different sizes, and the paper types stored in each paper storage unit can be pre-set in the system of the image forming device 10 or by a user. When the user issues a print job, the system will automatically select which paper storage unit to output paper from according to the print paper size included in the print command. Of course, the user can also manually select which paper storage unit to output paper from before issuing the print command.

[0074] Based on the above image forming device 10, the above self-service terminal device 20, and the above paper ejection mechanism, an embodiment of the present application provides an image forming control method, which specifically includes the following steps:

[0075] S101: Obtain paper information and / or preset paper size information on a conveying channel of the image forming device 10;

[0076] S102: Control the paper conveyer 155 state of the image forming device 10 based on the paper information and / or preset paper size information on the conveying channel of the image forming device 10, wherein the rear part of the image forming device 10 extends to the front part of the paper ejection channel 151, the first paper ejection tray 153 and the second paper ejection tray 154 are arranged on the paper ejection channel 151, the paper conveyer 155 is arranged between the first paper ejection tray 153 and the second paper ejection tray 154, when the paper conveyer 155 is in a paper conveying state, the paper conveyer 155 is used to convey the output from the conveying channel 16 of the image forming device through the first paper ejection tray 153 to the second paper ejection tray 154, and when the paper conveyer 155 is in a non-paper conveying state, the output from the conveying channel 16 is directly conveyed to the first paper ejection tray 153.

[0077] The execution subject of the above method can be an image forming control device, specifically a control unit included in the image forming device 10.

[0078] The conveying channel includes at least one of the conveying channel 16 and the paper ejection channel 151.

[0079] The paper information on the conveying channel can be the size information of the paper existing on the conveying channel 16, or the paper presence information of whether there is paper on the conveying channel 16 and / or the paper ejection channel 151, or a preset jam event occurring on the conveying channel 16 and / or the paper ejection channel 151, which is not limited here.

[0080] The preset paper size information can be a preset threshold of the paper size, or a user-set expected use of the print paper size, i.e., the paper size information included in the print command, or can include the paper size information included in the print command and the preset threshold, which is not limited here.

[0081] For details on obtaining the paper information and / or preset paper size information on the transport channel of the aforementioned image forming apparatus, please refer to the following description.

[0082] The output component of the conveying channel 16 can be a discharge component output from the image forming apparatus 10 via the conveying channel 16, and can be a blank output component or a printout with an image printed on it; there is no limitation on this.

[0083] Specifically, controlling the state of the paper conveyor 155 of the image forming apparatus 10 includes: controlling the paper conveyor 155 to enter a non-paper conveying state, in which case the action of conveying the output component passing through the first paper tray 153 to the second tray 154 is not performed, and the output component output from the conveying channel 16 of the image forming apparatus 10 is directly conveyed to the first paper tray 153; or controlling the paper conveyor 155 to enter a paper conveying state, thereby performing the action of conveying the output component passing through the first paper tray 153 to the second paper tray 154, so that the output component output from the conveying channel 16 of the image forming apparatus 10 is conveyed to the second paper tray 154.

[0084] Specifically, the control unit determines the current state of the paper conveyor 155 by judging the detection result of the sensor 151a. If the current state of the paper conveyor 155 meets the preset requirements, the state of the paper conveyor 155 is maintained. If the current state of the paper conveyor 155 does not meet the preset requirements, the state of the paper conveyor 155 is adjusted to the desired state.

[0085] Furthermore, the method of determining the current state of the paper conveyor 155 based on the detection results of the sensor 151a, and then adjusting or maintaining the state of the paper conveyor 155, is described in the foregoing and will not be repeated here.

[0086] In this embodiment, by controlling the state of the paper conveyor 155, the output of the image forming device 10 is output to one of the first paper tray 153 and the second paper tray 154, so that the output of the image forming device 10 can be taken by the user, bringing convenience to the user.

[0087] The following is in conjunction with the appendix Figures 8-10 The specific implementation of S102 will be explained in detail.

[0088] like Figure 7 As shown, the paper information on the conveying channel can specifically refer to whether there is paper on the output conveying channel. In S102 above, based on the paper information on the conveying channel of the image forming apparatus 10 and / or preset paper size information, the state of the paper conveyor 155 of the image forming apparatus 10 is controlled, specifically including the following steps:

[0089] S701: When the image forming apparatus 10 is powered on, it is determined whether there is paper on the output conveying path of the image forming apparatus 10. If yes, go to S702.

[0090] S702: Control the paper conveyer 155 of the image forming apparatus 10 to be in the paper conveying state.

[0091] Specifically, in S701, when the image forming apparatus 10 is powered on, it specifically refers to the scenario that the image forming apparatus 10 is powered on but has not received a print command.

[0092] In some scenarios, when the image forming apparatus 10 is powered on, the paper feed mechanism 131 of the image forming apparatus 10 will automatically feed a blank paper to make the blank paper enter the conveying path 16. When the blank paper passes through one or more of the fourth sensor S4, the second sensor S2, the fifth sensor S5, and the sixth sensor S6 in the conveying path 16, one or more of the fourth sensor S4, the second sensor S2, the fifth sensor S5, and the sixth sensor S6 will be pressed by the paper and activated, and the control unit determines that the blank paper exists in the conveying path 16.

[0093] When the image forming apparatus 10 is powered on and the conveying path has the blank paper, the control unit controls the state of the paper conveyer 155 to be in the paper conveying state, and performs conveying the blank paper output from the conveying path 16 through the first paper discharge tray 153 to the second paper discharge tray 154, which specifically includes that when the control unit determines that the conveying path has the blank paper, the control unit queries the detection result of the sensor 151a to determine the current state of the paper conveyer 155. If the paper conveyer 155 is currently in the non-paper conveying state, the state of the paper conveyer 155 is adjusted to the paper conveying state, so that the blank paper is conveyed to the second paper discharge tray 154. If the paper conveyer 155 is currently in the paper conveying state, the state of the paper conveyer 155 is maintained unchanged, and the blank paper is conveyed to the second paper discharge tray 154.

[0094] In the above scheme provided by the embodiment of the present application, when the image forming apparatus is powered on and has not received a print command, if it is detected that there is paper in the conveying path, when the size information of the paper in the conveying path cannot be known, the paper conveyer 155 is controlled to be in the paper conveying state to make the output of the conveying path 16 of the image forming apparatus to be discharged to the second paper discharge tray 154, and it is determined that the output of the conveying path 16 of the image forming apparatus is conveyed to the second paper discharge tray 154, which effectively avoids the technical problem that when the size of the paper in the conveying path is small, the blank paper is directly output to the first paper discharge tray 153 and stays in the self-service terminal and cannot be taken away by the user, and brings convenience to the user.

[0095] As Figure 8As shown, when the paper information on the conveying path is specifically the size information of the paper on the conveying path 16, and the preset paper size information is the paper size information contained in the print command, the control of the paper conveyer 155 state of the image forming device 10 based on the paper information on the conveying path of the image forming device 10 and / or the preset paper size information in the above S102 specifically includes the following steps:

[0096] S801: Obtain the print paper size information contained in the print command.

[0097] S802: Obtain the size information of the paper existing in the conveying path 16.

[0098] After the image forming device 10 receives the print command, the paper is picked up by the paper feed mechanism 131 and enters the conveying path 16, and then passes through the fourth sensor S4 arranged in the conveying path 16. The fourth sensor S4 will be pressed and started by the paper, so that the system knows the position passed by the paper. Further, the system will calculate the time from the start to the close of the fourth sensor S4, and according to the paper conveying speed, the size information of the paper in the conveying path 16 along the paper conveying direction can be obtained.

[0099] S803: Determine whether the size information of the paper existing in the conveying path 16 matches the print paper size information contained in the print command? If yes, execute S804, if not, execute S805.

[0100] S804: Determine the state of the paper conveyer based on the size information of the paper existing in the conveying path, so that one output generated based on the print command is discharged to one of the first paper tray 153 and the second paper tray 154;

[0101] S805: Control the paper conveyer 155 to be in the paper conveying state, so that one output generated based on the print command is discharged to the second paper tray 154, or determine the state of the paper conveyer 155 based on the size information of the paper existing in the conveying path 16, so that one output generated based on the print command is discharged to one of the first paper tray 153 and the second paper tray 154.

[0102] Wherein, the determination of whether the size information of the paper existing in the conveying path 16 matches the print paper size information contained in the print command is specifically by comparing whether the length of the print paper size information contained in the print command along the paper conveying direction is same as the length of the paper existing in the conveying path 16 along the paper conveying direction, if same, the above comparison result is matching, if different, the above comparison result is not matching.

[0103] Further, when determining whether the size information of the paper present in the conveying path 16 matches the print paper size information contained in the print command, specifically, the type of paper present in the conveying path 16 can be directly compared with the type of paper contained in the print command. If they are consistent, the comparison result is matched. If they are different, the comparison result is not matched. The type of paper can be, for example, A4, A5, etc.

[0104] After determining whether the size information of the paper present in the conveying path 16 matches the print paper size information contained in the print command, if they are not matched, a first output generated based on the print command is still generated, and the paper conveyer 155 is controlled to be in the paper conveying state, so that the first output generated based on the print command is output to the second paper ejection tray 154, the printing operation is stopped, and prompt information indicating that the print paper size contained in the print command does not match the size of the paper actually present in the conveying path 16 of the image forming apparatus 10 is prompted. The paper ejection tray of the first output generated based on the print command can also be determined based on the size of the paper actually present in the conveying path 16 of the image forming apparatus 10.

[0105] In S804, the state of the paper conveyer 155 is determined based on the print paper size contained in the print command or the size of the paper actually present in the conveying path 16, so that the output generated based on the print command is ejected to one of the first paper ejection tray 153 and the second paper ejection tray 154. In S805, the state of the paper conveyer 155 is controlled based on the size of the paper actually present in the conveying path 16, so that the output generated based on the print command is ejected to one of the first paper ejection tray 153 and the second paper ejection tray 154, i.e., the state of the paper conveyer 155 is controlled based on the size of the paper, so that the output generated based on the print command is ejected to one of the first paper ejection tray 153 and the second paper ejection tray 154. The specific implementation is as shown in the following steps. Figure 9

[0106] S901: Determine the size relationship between the paper size information and the preset threshold value. If the paper size information is smaller than the preset threshold value, proceed to S902. If not, proceed to S903.

[0107] If yes, proceed to S902. If not, proceed to S903.

[0108] S902: Control the paper conveyer 155 to be in the paper conveying state, so that the output generated based on the print command is ejected to the second paper ejection tray 154.

[0109] S903: Control the paper conveyer 155 to be in the non-paper conveying state, so that the output generated based on the print command is ejected to the first paper ejection tray 153.

[0110] ​The preset threshold value can be pre-stored in a storage unit of the image forming device 10 or directly set in a computer program included in a control unit of the image forming device 10, which is not limited herein.

[0111] The paper size information can be length information of the paper along a paper conveying direction or paper type information such as A4, A5, etc. Specifically, when the paper size information is the length information of the paper along the conveying direction, the preset threshold value is a value or a value range representing the length information of the paper, which is not limited herein. When the paper size information is the paper type information, the preset threshold value is a specific paper type, which can include multiple paper types, which is not limited herein.

[0112] The above scheme provided by the embodiment of the present application can output the first output generated based on the print command even if the paper actually existing in the conveying channel 16 does not match the print paper size expected to be used by the user, avoid information leakage caused by the first output with data remaining in the self-service terminal, and bring good experience to the user.

[0113] Further, when the paper actually existing in the conveying channel 16 matches the print paper size expected to be used by the user, the paper tray of the output generated by the image forming device is determined based on the size information of the paper, so that the output of the image forming device can be taken away by the user, bringing good experience to the user.

[0114] Further, when the paper actually existing in the conveying channel 16 does not match the print size expected to be used by the user, the paper tray of the output generated by the image forming device is determined based on the paper actually existing in the conveying channel 16, or the output generated by the image forming device is directly output to the second paper tray 154, so that the output of the image forming device can be taken away by the user, bringing good experience to the user.

[0115] Further, the preset paper size information in S101 can be the paper size information included in the print command and the preset threshold value, and the determination of the paper tray of the output of the image forming device 10 is referred to S901-902, which is not repeated herein, wherein the paper size information in S901 is specifically the paper size information included in the print command.

[0116] The above scheme provided by the embodiment of the present application determines the paper tray of the output generated by the image forming device based on the size information of the paper, so that the output of the image forming device 10 can be taken away by the user, avoids information leakage caused by the output with data remaining in the self-service terminal, and brings good experience to the user.

[0117] Further, when the image forming apparatus 10 detects a preset paper jam event occurring in the conveying path 16 and / or the paper discharge path 151, the image forming apparatus 10 continues to convey the paper and controls the paper conveyer 155 to be in the paper conveying state, so that the paper existing in the conveying path 16 and / or the paper discharge path 151 is discharged to the second paper discharge tray 154.

[0118] In the above scheme, after the image forming apparatus 10 receives a print command, the paper feed mechanism 131 of the image forming apparatus 10 feeds the paper to enter the conveying path 16 and the paper discharge path 151, and when the paper passes through one or more of the fourth sensor S4 and the fifth sensor S5 arranged in the conveying path 16 or the second sensor S2 arranged in the paper discharge path 151, one or more of the second sensor S2, the fourth sensor S4 and the fifth sensor S5 is pressed by the paper and is triggered, and when the fourth sensor S4 and / or the fifth sensor S5 and / or the second sensor S3 is not released after being triggered for more than a preset time, it is determined that the preset paper jam event occurs.

[0119] In the scheme provided by the embodiments of the present application, when the preset paper jam event occurs, the image forming apparatus 10 continues to convey the paper and discharges the paper to the second paper discharge tray 154 closer to the paper outlet 104 for the user to take the paper, thereby avoiding the information security problem caused by the paper staying in the self-service terminal device and bringing convenience to the user.
