Description

The present invention relates to an image forming apparatus and an auto-reset control method.

Generally, image forming devices (printers, copiers, facsimile machines, etc.) that utilize electrophotographic process technology create electrostatic latent images by irradiating (exposure) a charged photoreceptor with laser light based on image data. Form. Then, by supplying toner from a developing device to the photoconductor on which the electrostatic latent image is formed, the electrostatic latent image is visualized and a toner image is formed. Further, this toner image is transferred to a sheet of paper in a transfer nip, and the sheet onto which the toner image has been transferred is heated and pressurized to be fixed in a fixing nip, thereby forming a toner image on the sheet of paper.

In image forming devices, users can set various item values such as paper size, orientation, number of copies, magnification, density, etc. as the device's default values (standard settings) on the settings screen for copying, faxing, etc. . If the user copies, for example, with setting values different from the default values, the user changes the settings to the desired values and then copies.

The image forming apparatus displays an operation screen, and if a predetermined period of time has elapsed without any user interaction, the image forming apparatus has an automatic function that transitions from the operation screen to the default screen and resets the settings set on the operation screen to the default values. Equipped with a reset function. By executing this auto-reset function, it is possible to prevent other users from unintentionally making copies while the setting values remain changed from the default values.

As a technology related to the auto-reset function, an image forming apparatus has been proposed that can start up in a disabled mode in which the auto-reset function is disabled, when the user wants to start up with the auto-reset function disabled (for example, , see Patent Document 1).

Japanese Patent Application Publication No. 2008-139402

By the way, when a user sends a print job to an image forming apparatus from a personal computer, the job status screen may be opened in order to check when the print job sent by the user will be output on the operation screen of the image forming apparatus. .

In this case, when the user is checking the status of the print job, the user only looks at the status and does not perform any operations, so the auto-reset function is executed against the user's intention, and the screen returns to the default screen. There was a problem with this. At this time, the user needs to re-enter the job status screen in order to check the status of the print job, which is inconvenient.

Here, since the settings screen for copying, faxing, etc. is a screen that is operated by the user, the auto-reset function will not usually be reset by operation while the user is using it. On the other hand, since the status confirmation screen is primarily a screen for the user to confirm the status, the user often does not perform any operations on it for a long time.

Note that it is possible to solve the above problem by using the technique described in Patent Document 1 and starting the image forming apparatus in a disabled mode in which the auto-reset function is disabled. However, in this case, even if the settings screen is displayed and a predetermined period of time has elapsed without any user interaction, the auto-reset function is not executed, so the settings remain changed from the default values and other users may not be able to use them. Another problem arises in that there is a possibility of copying or the like.

The control unit 100 includes a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, and the like. The CPU 101 reads a program according to the processing content from the ROM 102, loads it into the RAM 103, and centrally controls the operation of each block of the image forming apparatus 1 in cooperation with the loaded program. At this time, various data such as an LUT (Look Up Table) stored in the storage unit 72 are referred to. The storage unit 72 is composed of, for example, a nonvolatile semiconductor memory (so-called flash memory) or a hard disk drive.

The control unit 100 transmits and receives various data to and from an external device (for example, a personal computer) connected to a communication network such as a LAN (Local Area Network) or a WAN (Wide Area Network) via the communication unit 71. conduct. For example, the control unit 100 receives image data transmitted from an external device, and forms an image on paper based on this image data (input image data). The communication unit 71 is composed of a communication control card such as a LAN card, for example.

The image reading unit 10 includes an automatic document feeding device 11 called an ADF (Auto Document Feeder), a document image scanning device (scanner) 12, and the like.

The automatic document feeder 11 uses a conveyance mechanism to convey the document D placed on the document tray and sends it to the document image scanning device 12 . The automatic document feeder 11 can continuously read images (including both sides) of a large number of documents D placed on a document tray at one time.

The document image scanning device 12 optically scans the document D conveyed onto the contact glass from the automatic document feeder 11 or the document D placed on the contact glass, and converts the reflected light from the document D into a CCD ( Charge Coupled Device) An image is formed on the light-receiving surface of the sensor 12a, and the original image is read. The image reading unit 10 generates input image data based on the reading result by the original image scanning device 12. This input image data is subjected to predetermined image processing in the image processing section 30.

The operation display unit 20 is configured with, for example, a liquid crystal display (LCD) with a touch panel, and functions as a display unit 21 and an operation unit 22. The display unit 21 displays various operation screens and the operating status of each function in accordance with display control signals input from the control unit 100. The operation unit 22 includes various operation keys such as a numeric keypad and a start key, receives various input operations from the user, and outputs operation signals to the control unit 100.

The image processing unit 30 includes a circuit and the like that performs digital image processing on input image data according to initial settings or user settings. For example, the image processing unit 30 performs gradation correction based on gradation correction data (gradation correction table) under the control of the control unit 100. The image processing unit 30 also performs various correction processes such as color correction and shading correction, compression processing, etc. in addition to gradation correction on the input image data. The image forming section 40 is controlled based on the image data subjected to these processes.

The image forming unit 40 includes image forming units 41Y, 41M, 41C, and 41K, and an intermediate transfer unit for forming images using colored toners of Y component, M component, C component, and K component based on input image data. 42 mag.

Image forming units 41Y, 41M, 41C, and 41K for Y component, M component, C component, and K component have similar configurations. For convenience of illustration and explanation, common components are indicated by the same reference numerals, and when distinguishing between them, Y, M, C, or K is added to the reference numerals. In FIG. 1, only the constituent elements of the image forming unit 41Y for the Y component are labeled, and the constituent elements of the other image forming units 41M, 41C, and 41K are omitted.

The image forming unit 41 includes an exposure device 411, a developing device 412, a photosensitive drum 413, a charging device 414, a drum cleaning device 415, and the like.

The photosensitive drum 413 includes, for example, an under coat layer (UCL), a charge generation layer (CGL), and a charge transport layer ( It is a photoreceptor that has photoconductivity and is constructed by sequentially laminating CTL (Charge Transport Layer). The photoconductor drum 413 is, for example, a negatively charged organic photoconductor (OPC).

The charging device 414 uniformly charges the surface of the photoconductive drum 413 to a negative polarity. The charging device 414 is a strocolon charger.

The exposure device 411 is composed of, for example, a semiconductor laser, and irradiates the photoreceptor drum 413 with laser light corresponding to an image of each color component. When positive charges are generated in the charge generation layer of the photoreceptor drum 413 by laser light irradiation and are transported to the surface of the charge transport layer, the surface charges (negative charges) of the photoreceptor drum 413 are neutralized. As a result, electrostatic latent images of each color component are formed on the surface of the photoreceptor drum 413 due to potential differences with the surroundings.

The developing device 412 stores developers of each color component (for example, a two-component developer consisting of a small particle diameter toner and a carrier (magnetic material)), and applies the toners of each color component to the surface of the photoreceptor drum 413. By adhering it, the electrostatic latent image is visualized to form a toner image. The developing roller in the developing device 412 includes a cylindrical developing sleeve 412A that is rotationally driven, and a cylindrical magnetic roller that is inserted into the developing sleeve 412A and fixed to the housing of the developing device 412 so as not to rotate. .

The magnetic roller has a plurality of magnets arranged along its circumferential direction, and the carrier is carried on the outer circumferential surface of the developing sleeve 412A by the magnetic force and is conveyed to a position facing the photoreceptor drum 413 (developing position). It stands up to form a magnetic brush. At the development position, the toner that has been electrostatically attracted to the carrier and transported moves toward the photoreceptor drum 413 due to the potential difference between the developing sleeve 412A and the photoreceptor drum 413, and the electrostatic latent formed on the circumferential surface of the toner moves toward the photoreceptor drum 413. The image is developed.

The drum cleaning device 415 has a drum cleaning blade that comes into sliding contact with the surface of the photoreceptor drum 413. Transfer residual toner remaining on the surface of the photoreceptor drum 413 after the primary transfer is scraped off and removed by a drum cleaning blade.

The intermediate transfer unit 42 includes an intermediate transfer belt 421, a primary transfer roller 422, a plurality of support rollers 423, a secondary transfer roller 424, a belt cleaning device 426, and the like.

The intermediate transfer belt 421 is an endless belt, and is stretched around a plurality of support rollers 423 in a loop shape. At least one of the plurality of support rollers 423 is configured as a driving roller, and the others are configured as driven rollers. For example, it is preferable that a roller 423A disposed downstream of the primary transfer roller 422 for the K component in the belt running direction is a driving roller. This makes it easier to maintain a constant running speed of the belt in the primary transfer section. As the drive roller 423A rotates, the intermediate transfer belt 421 runs in the direction of arrow A at a constant speed.

The intermediate transfer belt 421 is a conductive and elastic belt, and has a high resistance layer on its surface. Intermediate transfer belt 421 is rotationally driven by a control signal from control section 100.

The primary transfer roller 422 is arranged on the inner peripheral surface side of the intermediate transfer belt 421, facing the photosensitive drum 413 of each color component. By pressing the primary transfer roller 422 against the photoreceptor drum 413 with the intermediate transfer belt 421 in between, a primary transfer nip for transferring the toner image from the photoreceptor drum 413 to the intermediate transfer belt 421 is formed.

The secondary transfer roller 424 is arranged on the outer peripheral surface side of the intermediate transfer belt 421, facing the backup roller 423B, which is arranged downstream of the drive roller 423A in the belt running direction. By pressing the secondary transfer roller 424 against the backup roller 423B with the intermediate transfer belt 421 in between, a secondary transfer nip for transferring the toner image from the intermediate transfer belt 421 to the paper S is formed.

When the intermediate transfer belt 421 passes through the primary transfer nip, the toner images on the photoreceptor drum 413 are primary transferred onto the intermediate transfer belt 421 in a sequentially overlapping manner. Specifically, by applying a primary transfer bias to the primary transfer roller 422 and applying an electric charge of opposite polarity to the toner to the back side of the intermediate transfer belt 421, that is, the side that contacts the primary transfer roller 422, the toner image is The image is electrostatically transferred to the intermediate transfer belt 421.

Thereafter, when the paper S passes through the secondary transfer nip, the toner image on the intermediate transfer belt 421 is secondarily transferred to the paper S. Specifically, by applying a secondary transfer bias to the secondary transfer roller 424 and applying an electric charge of opposite polarity to the toner to the back side of the paper S, that is, the side that comes into contact with the secondary transfer roller 424, the toner image is is electrostatically transferred to the paper S. The paper S onto which the toner image has been transferred is conveyed toward the fixing section 60.

The belt cleaning device 426 removes transfer residual toner remaining on the surface of the intermediate transfer belt 421 after the secondary transfer.

The fixing section 60 includes an upper fixing section 60A having a fixing surface side member disposed on the fixing surface of the paper S, that is, the surface on which the toner image is formed, and an upper fixing section 60A disposed on the back surface of the paper S, that is, the surface opposite to the fixing surface. The fixing unit 60B includes a lower fixing section 60B having a back side support member, a heat source, and the like. By pressing the back side support member against the fixing side member, a fixing nip is formed that nip and convey the paper S.

The fixing unit 60 fixes the toner image onto the paper S by heating and pressurizing the paper S to which the toner image has been secondarily transferred and being conveyed using a fixing nip. The fixing section 60 is arranged within the fixing device F as a unit.

The upper fixing section 60A includes an endless fixing belt 61, a heating roller 62, and a fixing roller 63, which are members on the fixing surface side. The fixing belt 61 is stretched between a heating roller 62 and a fixing roller 63.

The lower fixing section 60B has a pressure roller 64 that is a back side support member. The pressure roller 64 and the fixing belt 61 form a fixing nip in which the paper S is conveyed while being held therebetween.

The paper transport section 50 includes a paper feed section 51, a paper discharge section 52, a transport path section 53, and the like. The three paper feed tray units 51a to 51c constituting the paper feed section 51 accommodate sheets S (standard paper, special paper) that are identified based on basis weight, size, etc., according to preset types. .

The sheets S stored in the paper feed tray units 51a to 51c are fed out one by one from the top and conveyed to the image forming section 40 by a conveyance mechanism equipped with a plurality of conveyance rollers such as registration rollers 53a. At this time, the inclination of the fed sheet S is corrected and the conveyance timing is adjusted by the registration section provided with the registration rollers 53a. Then, in the image forming section 40, the toner image on the intermediate transfer belt 421 is transferred onto one side of the paper S, and a fixing process is performed in the fixing section 60. The paper S, on which the toner image has been fixed in the fixing process, is discharged to the outside of the image forming apparatus 1 by a paper discharge section 52 that includes a paper discharge roller 52a.

By the way, in the image forming apparatus 1, the user can set various item values such as the size and orientation of the paper S, the number of copies, magnification, density, etc. as the default values (standard setting values) of the apparatus on the setting screen for copying, faxing, etc. can do. If the user performs copying, for example, with setting values different from the default values, the user changes the setting values to the desired values before copying.

An operation screen is displayed on the image forming apparatus 1, and if a predetermined period of time has elapsed without any user operation, the operation screen is transitioned to a default screen, and the setting values set on the operation screen are reset to default values. Equipped with an auto-reset function. By executing this auto-reset function, it is possible to prevent other users from unintentionally making copies while the setting values remain changed from the default values.

Here, open the job status screen to send the print job from the personal computer to the image forming apparatus 1 and check on the operation screen of the image forming apparatus 1 when the print job sent by the user will be output. There are cases.

In this case, when the user is checking the status of the print job, the user only looks at the status and does not perform any operations, so the auto-reset function is executed against the user's intention, and the screen returns to the default screen. There was a problem with this. At this time, the user needs to re-enter the job status screen in order to check the status of the print job, which is inconvenient.

Since the setting screen for copying, faxing, etc. is a screen that is operated by the user, the auto-reset function will not normally be reset by the user's operation while the screen is being used. On the other hand, since the status confirmation screen is primarily a screen for the user to confirm the status, the user often does not perform any operations on it for a long time.

Therefore, in the present embodiment, when the first screen is displayed and a first predetermined period of time has elapsed without any user operation, the control unit 100 changes the screen from the first screen to the second screen (for example, the default screen). ) and controls to change whether or not to execute an auto-reset function that resets the setting values set on the first screen to default values, depending on the type of the first screen.

Specifically, when the first screen is a settings screen (for example, a print settings screen) where the user makes settings for the image forming apparatus 1, the control unit 100 causes the auto-reset function to be executed. On the other hand, when the first screen is a status display screen that displays the status of the image forming apparatus 1, the control unit 100 does not cause the auto-reset function to be executed.

Status display screens include a job status screen that displays the execution status of print jobs instructed by the user, a counter screen that displays the number of executions of copy/print/scan, etc., and a consumables check that displays the status of consumables. Examples include an apparatus information display screen that displays the IP address, serial number, etc. of the image forming apparatus 1, and an information screen that displays, for example, a message indicating the time to replace the toner cartridge as warning information.

FIG. 3 is a flowchart showing an example of the operation of the image forming apparatus 1 in this embodiment. Note that the process shown in FIG. 3 is executed every time a predetermined time (for example, 1 second) passes when the operation screen is displayed on the display unit 21.

First, the control unit 100 determines whether the operation screen (first screen) displayed on the display unit 21 is a setting screen (step S100). As a result of the determination, if the operation screen is a settings screen (step S100, YES), the control unit 100 determines whether or not the settings screen is displayed and a first predetermined period of time has elapsed without any user operation. (Step S120).

As a result of the determination, if the first predetermined time has not elapsed (step S120, NO), the image forming apparatus 1 ends the process in FIG. 3. On the other hand, if the first predetermined time has elapsed (step S120, YES), the setting screen is transitioned to a default screen (second screen), and the setting values set on the setting screen are reset to default values. The auto-reset function is executed (step S140). Upon completion of the process in step S140, the image forming apparatus 1 ends the process in FIG. 3.

Returning to the process of step S100, if the operation screen is not a settings screen, that is, if it is a status display screen (for example, a job status screen that displays the execution status of a print job instructed to be executed by the user) (step S100, NO ), the control unit 100 determines whether or not the status display screen has been displayed for a second predetermined time period that is longer than the first predetermined time period (step S160). The second predetermined time is set, for example, to a time that allows the user to sufficiently check the execution status of the print job.

As a result of the determination, if the second predetermined time has not elapsed (step S160, NO), the image forming apparatus 1 ends the process in FIG. 3. On the other hand, if the second predetermined time has elapsed (step S160, YES), the control unit 100 determines whether a user (for example, a user who has instructed execution of a print job) is present near the image forming apparatus 1. It is determined whether (step S180).

In the present embodiment, when a mobile terminal (for example, a smartphone) used by a user and the image forming apparatus 1 are located within a predetermined distance, the control unit 100 controls the It is confirmed whether short-range communication such as Bluetooth (registered trademark) LE has been established (that is, whether user authentication has been successful). If the control unit 100 confirms that the user authentication has been successful, it determines that the user is present near the image forming apparatus 1 . On the other hand, if the control unit 100 does not confirm that the user authentication has been successful, it determines that there is no user near the image forming apparatus 1.

In step S180, if there is a user near the image forming apparatus 1 (YES), the status display screen continues to be displayed, and the image forming apparatus 1 ends the process in FIG. 3. On the other hand, if there is no user near the image forming apparatus 1 (step S180, NO), the control unit 100 causes a transition from the status display screen to the default screen (step S200). Upon completion of the process in step S200, the image forming apparatus 1 ends the process in FIG. 3.

As described in detail above, in the present embodiment, when the first screen is displayed and the first predetermined period of time has elapsed without any user operation, the image forming apparatus 1 switches from the first screen to the second screen. an auto-reset unit (control unit 100) that executes an auto-reset function that transitions to the screen (default screen) and resets the setting values set on the first screen to the default values; Accordingly, the control unit (control unit 100) controls the auto-reset unit to change whether or not to execute the auto-reset function.

According to this embodiment configured in this way, whether or not to execute the auto-reset function is changed depending on the type of the first screen. Specifically, when the first screen is a setting screen where the user makes settings for the image forming apparatus 1, the auto-reset function is executed. On the other hand, when the first screen is a status display screen that displays the status regarding image forming apparatus 1, the auto-reset function is not executed. Therefore, when a user is checking the status of a print job on the job status screen (status display screen), the auto-reset function may be activated against the user's intention, even if the user only looks at the status and does not perform any operations. It will no longer be executed. That is, the user does not need to re-enter the job status screen to check the status of the print job. Therefore, according to the image forming apparatus 1, the auto-reset function can be executed according to the user's intention.

Further, in the present embodiment, when the first screen is a status display screen, when the status display screen is displayed for a second predetermined time period that is longer than the first predetermined time period, the control unit 100 , to transition from the status display screen to the second screen. With this configuration, for example, it is possible to prevent the status display screen from continuing to be displayed unnecessarily until after the time (second predetermined time) that allows the user to sufficiently check the execution status of the print job has elapsed. can.

Furthermore, in the present embodiment, if it is determined that there is no user near the image forming apparatus 1, the control unit 100 causes the status display screen to change to the second screen when the second predetermined time period has elapsed. On the other hand, if it is determined that a user is present near the image forming apparatus 1, the status display screen is not transitioned to the second screen when the second predetermined time period has elapsed. With this configuration, even after the time period (second predetermined time period) in which the user can sufficiently check the execution status of the print job has elapsed, if the user is present near the image forming apparatus 1 (the user cannot confirm the execution status of the print job). If it is presumed that the user intends to continue checking the execution status of the user), the status display screen can be continued to be displayed without transitioning to the second screen according to the user's intention.

In addition, although the said embodiment demonstrated the example where the 2nd predetermined time is longer than the 1st predetermined time, this invention is not limited to this. For example, the second predetermined time may be less than or equal to the first predetermined time.

In the above embodiment, when the setting value is set on the setting screen and the setting screen is changed to the status display screen (returning), the control unit 100 controls the setting screen before changing to the setting screen. It is desirable to reset the configured setting values to default values. For example, setting values are reset to default values when transitioning from a settings screen to a status display screen or when transitioning from a status display screen to a settings screen. With such a configuration, for example, if a user checks the status of a print job after setting a fax destination (setting value) and then leaves the vicinity of the image forming apparatus 1, another user can change the setting value. Unintentional fax transmission (erroneous transmission) can be avoided.

Further, the above embodiments are merely examples of implementation of the present invention, and the technical scope of the present invention should not be construed as limited by these embodiments. That is, the present invention can be implemented in various forms without departing from its gist or main features.
