[0018] Figure 11 This is a diagram illustrating an example of operation in the third embodiment. Detailed Implementation

[0019] Generally, image forming apparatuses include sensors for image quality adjustment. Here, for example, in an image forming apparatus capable of cleaning sensor dirt through the opening and closing of a cover (door), it is known in the prior art, as soon as dirt is detected on the sensor, a message is issued requesting the user to open and close the cover to clean the sensor. For example, when the image forming apparatus detects dirt adhering to the sensor, it notifies the user by displaying a code indicating the dirt on the sensor, or an explanatory screen. The user then follows the notification to perform the cleaning steps shown in the manual or explanatory screen corresponding to the code (e.g., opening and closing the cover) to clean the sensor.

[0020] However, even when sensor contamination is detected based on the state of the image forming apparatus, there are situations where the aforementioned message cannot be output immediately. For example, during a copying job, if the engine output indication has been completed, the engine cannot be stopped until the output is finished. In this case, if a message is displayed to the user, there is a risk that the user might accidentally open the cover at an inappropriate time, such as during a copying job.

[0021] Furthermore, during the period before the image forming apparatus is in a state capable of issuing the aforementioned message, there is a possibility that the sensor may be unintentionally cleaned due to the need for opening and closing the cover for other reasons. Therefore, even when the image forming apparatus is in a state capable of issuing the aforementioned message, there is still a problem of determining whether to issue the aforementioned message.

[0022] Referring to the accompanying drawings, an image forming apparatus for solving such problems will be described in the following embodiments. Furthermore, the following embodiments are described using the claims as examples, and the scope of this disclosure is not limited to the embodiments described below.

[0023] [1. First Implementation Method] [1.1 Overall Composition] [1.1.1 Image forming apparatus] Figure 1 This is a diagram illustrating the overall configuration of the image forming apparatus 10.

[0024] The image forming apparatus 10 is, for example, a multifunction printer or an MFP (Multifunction Peripheral / Printer). For example, when the image forming apparatus 10 performs a job (printing job), it can form an image on paper or the like, which serves as a recording medium. As the job to be performed, the image forming apparatus 10 can perform multiple processes such as copying, faxing, scanning, and printing.

[0025] The image forming apparatus 10 has an openable and closable cover (cover component) 12 on its back side. Inside the cover 12, the image forming apparatus 10 has a cleaning mechanism for cleaning the sensor (sensor cleaning mechanism). The user can clean the sensor by sliding the cleaning mechanism, for example, by opening and closing the cover 12. Furthermore, when paper jams occur in the image forming apparatus 10, the user can clear the jam by opening the cover 12 and removing the jammed paper.

[0026] Furthermore, the image forming apparatus 10 includes a paper feeding unit 14. The paper feeding unit 14 includes, for example, a paper feeding tray, a manual tray, and a paper feeding roller for feeding paper to the image forming unit 160, which will be described later.

[0027] [1.1.2 Cleaning facilities] Next, refer to Figure 2 The cleaning mechanism of the image forming apparatus 10 is explained. Figure 2 This is a diagram showing an example of the cleaning mechanism of the image forming apparatus 10.

[0028] Figure 2 (a) is a perspective view illustrating an example of the image forming apparatus 10 viewed from the inside when the cover 12 is closed. Figure 2 As shown in (a), the image forming apparatus 10 has a cover 12, a sensor support unit 16, and a cleaning mechanism 18.

[0029] For example, the cover 12 is connected to the image forming apparatus 10 in an openable and closable state. The cover 12, for example, has a stop member 12a with a guiding function. Paper is fed from the paper feed section 14 to the image forming section 160 (from below to above) through the cover 12 and the sensor support unit 16.

[0030] For example, when a paper jam (paper blockage) occurs during copying, the user can remove the paper stuck between the cover 12 and the sensor support unit 16 by opening the cover 12.

[0031] The sensor support unit 16 has, for example, a sensor 16a and a sensor holding member (sensor support) 16b, and the sensor 16a is mounted on the sensor support unit 16 in an upward manner via the sensor holding member 16b.

[0032] Sensor 16a is one or more sensors provided for image quality adjustment. For example, it may be a registration control sensor, a process control sensor, or a sensor combining both functions that detects density or positional deviations in the images of each toner. Sensor 16a is protected, for example, by a cover glass.

[0033] The cleaning mechanism 18 includes, for example, a sensor cleaning plate 18a, one or more cleaning pads 18b, and a sensor cleaning rod 18c. The sensor cleaning plate 18a is mounted on the sensor 16a in a state that allows it to slide along the long side direction (LR direction) of the sensor support unit 16. One or more small windows may also be provided on the sensor cleaning plate 18a, for example, in a manner that does not obstruct the operation of the sensor 16a.

[0034] The cleaning pad 18b is, for example, a scraper, and is disposed on the sensor cleaning plate 18a in such a way that it abuts against the end of the cover glass of the sensor 16a.

[0035] The sensor cleaning rod 18c is connected to the sensor cleaning plate 18a at one end (in the F direction). Furthermore, the sensor cleaning rod 18c is connected to the sensor support unit 16 in a rotatable state. The other end (in the B direction) of the sensor cleaning rod 18c is secured by being inserted into the guide-function stop member 12a when the cover 12 is closed.

[0036] Figure 2 (b) is a perspective view showing an example of the cover 12 being in an open state, observed from the inside of the image forming apparatus 10. Figure 2 As shown in (b), by opening the cover 12, the sensor cleaning rod 18c disengages from the stop member 12a with a guiding function. Consequently, the end of the sensor cleaning rod 18c disengaged from the stop member 12a (in the B direction) rotates outward (in the R direction) via an elastic member (not shown here). On the other hand, the other end of the sensor cleaning rod 18c connected to the sensor cleaning plate 18a rotates inward (in the L direction), and the sensor cleaning plate 18a slides on the sensor support unit 16 (from the R direction toward the L direction) in conjunction with this inward rotation.

[0037] As the sensor cleaning plate 18a slides, the cleaning pad 18b, which abuts against one end (R side) of the cover glass of the sensor 16a, also slides together with the sensor cleaning plate 18a to the other end (L side) of the cover glass of the sensor 16a, thereby scraping off the toner adhering to the cover glass of the sensor 16a and completing the cleaning of the sensor 16a.

[0038] Furthermore, although only one example of the cleaning mechanism 18 is shown in this embodiment, any configuration can be used as long as the sensor 16a can be cleaned by operating the cover 12. For example, the cover 12 can be provided not only on the back of the image forming apparatus 10, but also on the front, left, or right sides.

[0039] [1.2 Hardware Configuration] The hardware configuration of the image forming apparatus 10 will now be described with reference to the accompanying drawings. Figure 3 This is a diagram illustrating an example of the hardware configuration of the image forming apparatus 10.

[0040] like Figure 3 As shown, the image forming apparatus 10 includes a control unit 100, a memory 110 which serves as one or more storage devices (storage units), a ROM (Read Only Memory) 120 and a RAM (Random Access Memory) 130, a display unit 140, an operation unit 150, an image forming unit 160, an image reading unit 165 and a communication unit 170.

[0041] The control unit 100 controls the entire image forming apparatus 10. The control unit 100 performs various functions by reading and executing various programs stored in a storage device (e.g., memory 110, ROM 120). The control unit 100 can be implemented by one or more control / processing units (CPU (Central Processing Unit), SoC (System on a Chip). Alternatively, the control unit 100 can also be composed of one or more control circuits.

[0042] The memory 110 is a non-volatile storage device capable of storing programs and data. For example, it may be composed of one or more storage devices such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive). Alternatively, the memory 110 may be configured as an external device such as a USB storage device that can be connected to the image forming apparatus 10. Furthermore, the memory 110 may also be, for example, a storage area located in the cloud.

[0043] ROM120 is one or more non-volatile memories that can retain programs and data even when the power is off.

[0044] RAM130 is mainly the main memory used by the control unit 100 during processing. RAM130 is one or more rewritable memories used to temporarily store programs read from the storage unit 110 and ROM120, as well as data containing the results of execution.

[0045] Display unit 140 is a display device capable of displaying various information, executing various screens, and so on. Display unit 140 may be, for example, a liquid crystal display (LCD), an organic electroluminescence (OLED) display, an electrophoretic display, or other display devices. Furthermore, display unit 140 includes interfaces that display devices can connect to. For example, it may be configured with an external display device connected via HDMI (High-Definition Multimedia Interface), DVI (Digital Visual Interface), or a DisplayPort.

[0046] The operation unit 150 is an operating device capable of receiving operation input from the user. For example, it may be a hardware key such as a software key or operation button displayed on a touch panel integrated with the display unit 140. Alternatively, the operation unit 150 may also be an operating device such as a keyboard or mouse. Furthermore, the operation unit 150 may include an interface (e.g., USB) for connecting operating devices. For example, the image forming apparatus 10 may also connect to different operating devices (keyboard, mouse, etc.) via the interface.

[0047] The image forming unit 160 forms an image, for example, on recording paper. The image forming unit 160 includes, for example, an image carrier, on which a toner image is formed, and then the toner image on the image carrier is transferred to the recording paper to form an image. The image forming unit 160 can also be configured as an image forming apparatus such as a printer. Furthermore, the image forming unit 160 can also form an image electronically as an image file. Additionally, the image forming unit 160 can also electronically generate an image file from an image.

[0048] The image reading unit 165 reads the original document (original image) and outputs it as image data. The image reading unit 165 may be, for example, a scanner, or a reading device that utilizes a CCD (Charge Coupled Device), CIS (Contact Image Sensor), or CMOS (Complementary Metal-Oxide-Semiconductor) image sensor.

[0049] The communication unit 170 is a communication interface for communicating with other devices. For example, it may be a network interface that can provide wired or wireless connections. In this embodiment, it can communicate with other devices via a network (NW).

[0050] [1.3 Software Composition] Reference Figure 4 The configuration of the main software in the image forming apparatus 10 will be explained. Furthermore, Figure 4 The software configuration shown mainly describes the configuration required in this embodiment, and other configurations are omitted.

[0051] For example, the control unit 100 can realize the stain detection unit 1010 and the operation execution unit 1020 by reading and executing the program stored in the storage unit (memory 110, ROM 120).

[0052] The stain detection unit 1010 detects stains on the sensor, such as stains like toner adhering to the cover glass of the sensor 16a. For example, the stain detection unit 1010 measures a reference indicator, and detects stains on the sensor when the measured value is below a predetermined threshold. When the stain detection unit 1010 detects stains on the sensor 16a, it can, for example, set the sensor cleaning flag in the flag information storage area 1110 to ON and store the information. Here, if the number of times the sensor is detected for stains exceeds a predetermined number, the sensor cleaning flag in the flag information storage area 1110 can be left off, and an error message indicating that the sensor cannot be cleaned can be sent.

[0053] The job execution unit 1020 performs various jobs. For example, depending on the type of job being executed, the job execution unit 1020 causes the image forming apparatus 10 to perform various actions. Here, job type refers to different types of jobs such as copying, scanning, printing, faxing, and faxing. For example, if it is a copying, printing, or faxing job, the paper feed unit 14 is activated; if it is a scanning job, the paper feed unit 14 is not activated. The job execution unit 1020 can store information about the actions performed by the image forming apparatus 10 through the execution of a job as flag information in the flag information storage area 1110.

[0054] The memory 110 ensures the storage of the marking information in the marking information storage area 1110. The marking information can also store information about the state of the image forming apparatus 10, such as whether cleaning is required from the sensor 16a, information about job-based actions such as whether the paper feed unit 14 is operating, and information about where a paper jam has occurred in the image forming apparatus 10. Here, see... Figure 5 An example of the marking information stored in the marking information storage area 1110 will be described. The marking information stores items of various states of the image forming apparatus 10 (e.g., "paper jam occurred") and values ​​corresponding to the items (e.g., "off"). Here, as values, "ON" and "OFF" can be stored. For example, if a paper jam occurs, "ON" can indicate that a paper jam is occurring, and "OFF" can indicate that a paper jam has not occurred.

[0055] [1.4 Processing Flow] The following is for reference Figure 6 The processing flow in this embodiment will be explained. Furthermore, although the following processing is described as being performed by the control unit 100 of the image forming apparatus 10, Figure 3 or Figure 4 Each component described herein can also perform its own processing steps.

[0056] First, the control unit 100 determines whether a stain on the sensor 16a is detected (S102). If the control unit 100 determines that a stain on the sensor is detected, it sets the sensor cleaning flag in the flag information storage area 1110 to ON and stores it (S102; Yes → S104). If the control unit 100 determines that no stain on the sensor is detected, it continues to determine whether a stain on the sensor is detected until a stain is detected (S102; No).

[0057] Next, the control unit 100 determines whether the image forming apparatus 10 has performed a paper feeding operation accompanied by the paper feeding unit 14 (S106). As a method for determining whether a paper feeding operation accompanied by the paper feeding unit 14 has been performed, the following method is considered.

[0058] As a first method, for example, when the control unit 100 performs a copying job, printing job, faxing job, or other operation that involves feeding paper from the paper supply unit 14 to the image forming unit 160, it determines that a paper feeding operation is in progress. As a second method, for example, when the control unit 100 is operating the paper supply unit 14, it determines that a paper feeding operation is in progress. As a third method, for example, when the control unit 100 determines that a paper feeding operation is in progress when the flag information stored in the flag information storage area 1110 indicates that the operation of the paper supply unit 14 caused by the execution of a job is in progress.

[0059] Here, if the control unit 100 determines that it is not in a paper feeding operation, it displays a notification requesting the cleaning of sensor 16a on the display unit 140 via a cover opening / closing request screen (display screen) (S106; No → S108). Furthermore, the cover opening / closing request screen can also be displayed as a cleaning dialog box, for example. On the other hand, when the control unit 100 is in a paper feeding operation, it continuously determines whether it is in a paper feeding operation until it determines that it is not in a paper feeding operation (S106; Yes).

[0060] Next, the control unit 100, assuming a cover that allows the cleaning mechanism to fold with the opening and closing of the cover, determines whether the cover 12 has been operated. For example, if it is determined that at least the cover 12 has been opened, the sensor cleaning flag in the flag information storage area 1110 is set to OFF and stored. The cover opening / closing request screen can be canceled (the display of the cover opening / closing request screen ends), and a notification requesting the cover to be closed is re-displayed on the display unit 140 (S110; Yes → S112). On the other hand, the control unit 100 may, for example, continue to display the cover opening / closing request screen on the display unit 140 until it is determined that at least the cover 12 has been opened (S110; No).

[0061] [1.5 Action Examples] Figure 7Figure (a) shows an example of a display screen W100 displayed on the display unit 140. The display screen W100 is, for example, an example of a display screen showing the settings for a copy job. In area R100 of the display screen W100, as selectable icons for setting the copy job, there are icons for selecting the original size, selecting the original type / density, and setting the sorting method (sorting / grouping) of the output paper.

[0062] Furthermore, here, "icon" refers to an icon displayed on the screen that represents various data and processing functions as patterns, graphic text, symbols, or text. By selecting an icon, the control unit 100 can execute the processing set by the icon.

[0063] Furthermore, the display screen W100 shows the monochrome copy execution button B100 and the color copy execution button B102. Here, if the control unit 100 detects dirt on the sensor during the display screen W100's display, the control unit 100 will display... Figure 7 The display screen W104 (c) serves as a cover opening / closing request screen. Here, in the display screen W100, for example, when the user selects the monochrome copy execution button B100 or the color copy execution button B102, the control unit 100 executes the monochrome or color copy operation respectively and displays... Figure 7 The display screen (b) is W102.

[0064] Figure 7 Figure (b) shows an example of a display screen W102 displayed on the display unit 140. The display screen W102 is, for example, an example of a display screen during a copying operation accompanied by a paper feeding action. In area R102 of the display screen W102, and... Figure 7 (a) The various icons in area R100 are displayed in a light color as they are not selectable. Furthermore, display screen W102 shows the copy stop button B104. Here, if the copy job has ended, and the control unit 100 detects stains on the sensor during the copy job execution, the control unit 100 displays... Figure 7 The display screen W104 of (c) serves as the cover opening / closing request screen.

[0065] Furthermore, if the user selects, for example, the copy stop button B104, the control unit 100 displays the following after stopping the ongoing operation: Figure 7 The display screen W100 (a) shows the following. Here, similar to the case when the copying job is completed, when the control unit 100 detects stains on the sensor, the control unit 100 displays... Figure 7The display screen (c) W104 serves as a cover opening / closing request screen. Thus, unlike the display screen W100, in the display screen W102, even if the control unit 100 detects dirt on the sensor and a copying operation accompanied by paper feeding is in progress (paper feeding in progress), the control unit 100 suppresses the display of the cover opening / closing request screen.

[0066] Furthermore, in situations where a task without paper feeding is performed, such as a scanning task, the paper feeding unit 14 does not operate. In this case, when the control unit 100 detects dirt on the sensor, the control unit 100 displays... Figure 7 The display screen W104 of (c) serves as the cover opening / closing request screen.

[0067] Figure 7 Figure (c) shows an example of a display screen W104 displayed on the display unit 140. Display screen W104 is, for example, an example of a cover opening / closing request screen. The display screen W104 displays the message M100: "The sensor needs cleaning. Please open and close the back cover. Cleaning is performed by opening and closing the cover." Here, for example, when the user opens the cover 12, the control unit 100 displays on the display unit 140. Figure 7 The display screen of (d) is W106.

[0068] Figure 7 Figure (d) shows an example of a display screen W106 displayed on the display unit 140. Display screen W106 is, for example, an example of a display screen displayed on the display unit 140 when the cover 12 is open. The display screen W106 displays the message M102: "Please close the back cover." Here, for example, when the user closes the cover 12, the control unit 100 displays on the display unit 140. Figure 7 The display screen (a) is W100.

[0069] In addition, in this embodiment, a cover opening / closing request screen is displayed when a cover opening / closing request is made. However, the control unit 100 may display images, graphics, or text related to the cover opening / closing request on the display screen W100, or it may notify the user by sound instead of displaying the image. Alternatively, the control unit 100 may also display a cover opening / closing request screen or other notifications related to the cover opening / closing request on the display screen of another device, such as an information processing device like a terminal device, via the communication unit 170.

[0070] In this way, when the control unit 100 detects dirt on the sensor, it controls the display of a notification message to the user based on the state of the image forming apparatus. When the control unit 100 detects dirt on the sensor, it determines whether the cover is in an openable / closable state based on the state of the image forming apparatus. If the cover is in an openable / closable state, it notifies the user of an operation request (cover opening / closing request).

[0071] When the control unit 100 detects stains on the sensor and the cover 12 is in a state where it cannot be opened or closed during a copying operation, such as when the user is performing a paper feeding action (e.g., "copying in progress"), it does not display and suppresses the sensor cleaning operation request to prevent the user from accidentally opening the cover 12. Furthermore, since the control unit 100 can display the sensor cleaning operation request when it detects stains on the sensor and the cover 12 is openable or closed during a copying operation where paper feeding has stopped, the user can perform sensor cleaning without hindering the execution of the operation accompanying the paper feeding action.

[0072] [1.6 Effects, etc.] Users can clean the sensor by a simple operation (opening and closing the cover) at the appropriate time when the paper feeding action stops (when the cover can be opened and closed), without accidentally opening the cover when it is not openable and the paper feeding action is in progress, such as during a copying job.

[0073] [2. Second Implementation] The second embodiment will now be described. The second embodiment is as follows: the sensor is cleaned by closing the cover 12 after the paper jam is cleared, and the opening and closing request screen for the sensor cleaning cover 12 is not displayed.

[0074] The second embodiment omits descriptions of the hardware and software components that are the same as those in the first embodiment, and focuses on the differences from the first embodiment.

[0075] [2.1 Processing flow] The following is for reference Figure 8 The processing flow of this embodiment will be explained. Figure 8 It is a replacement for the first embodiment. Figure 6 The image. Figure 6 Between S106 and S108, S202 to S206 are executed.

[0076] If the control unit 100 determines that it is not in the process of feeding paper, for example, it determines whether a paper jam (paper blockage) has occurred (S106; No → S202). If a paper jam occurs, the control unit 100 displays a display screen (paper jam warning dialog box) (S202; Yes → S204).

[0077] Next, when the control unit 100 performs the operation to clear a paper jam, it determines, for example, whether the cover 12 has been operated to remove the paper jam. If it determines that the cover 12 has been operated, it executes process S112 (S206; Yes → S112). If it determines that the cover 12 has not been operated, it displays a cover opening / closing request screen (S206; No → S108). Here, a case where the cover 12 is not operated when performing the operation to clear a paper jam can be exemplified by a paper jam occurring in a document feeding device such as an ADF (Automatic Document Feeder).

[0078] Furthermore, the above-described operation flow is just one example, and some different processes can also be performed. In this embodiment, if it is determined that the paper feeding operation is not in progress, it is determined whether a paper jam has occurred. However, for example, it is also possible to determine whether the paper feeding unit 14 is out of paper before S202. If the paper feeding unit 14 is not out of paper, the process is transferred to S202. If the paper feeding unit 14 is out of paper, an opening / closing request screen is displayed (process S110 is executed). After the cover 12 is operated, the process of displaying that the paper is out of paper is executed.

[0079] [2.2 Action Examples] Figure 9 This diagram shows an example of a display screen W200 displayed on the display unit 140. The display screen W200 is, for example, an example of a display screen displayed on the display unit 140 when a work being performed is interrupted due to a paper jam. The display screen W200 displays instructions for clearing the paper jam. Here, for example, when the user opens the cover 12, the control unit 100 displays on the display unit 140. Figure 7 The display screen of (d) is W106.

[0080] In this embodiment, even if the control unit 100 detects dirt on the sensor or a paper jam occurs, it displays a warning dialog box indicating a paper jam on the display screen. However, for example, it may also display an image, graphic, or text display related to the opening and closing request of the cover on the display screen W200, or it may notify the user by sound instead of displaying the image. Alternatively, the control unit 100 may also display a cover opening and closing request screen or other notifications related to the opening and closing request of the cover on the display screen of another device, such as an information processing device like a terminal device, via the communication unit 170.

[0081] [2.3 Effects, etc.] In the image forming apparatus 10 with a sensor cleaning mechanism, if the user opens and closes the cover 12 for a purpose different from cleaning the sensor, such as removing a paper jam, and thus completes the sensor cleaning, the operation request for cleaning the sensor (the opening and closing request of the cover 12) is not notified again. In this way, the user can complete the sensor cleaning without having to perform the opening and closing operation of the cover 12 again just to clean the sensor.

[0082] [3. Third Implementation Method] The third embodiment will now be described. The third embodiment is as follows: when the control unit 100 detects a stain on the sensor, but the cover 12 cannot be opened or closed during a copying operation accompanied by paper feeding, an icon indicating that a stain on the sensor has been detected is displayed.

[0083] In the third embodiment, the description of the parts that are the same as those in the first embodiment in terms of hardware and software configuration is omitted, and the description focuses on the differences from the first embodiment.

[0084] [3.1 Processing Flow] The following is for reference Figure 10 The processing flow in this embodiment will be explained. Figure 10 It is a replacement for the first embodiment. Figure 6 The image. Figure 6 S106 is followed by S302.

[0085] When the control unit 100 determines that a stain has been detected on the sensor but is in the process of feeding paper, it may, for example, issue a notification related to the detection of the stain on the sensor (S106; Yes → S302). Here, as a method of issuing a notification related to the detection of the stain on the sensor, the control unit 100 may also display a stain detection icon. The stain detection icon may be, for example, an image display, a graphic display, or a text display; it may be used to notify (inform) the user only, or the user may select the icon.

[0086] [3.2 Action Examples] Figure 11 This is a diagram showing an example of a display screen W300 displayed on the display unit 140. The display screen W300 is, for example, an example of a display screen showing a copying operation. On the display screen W300, similar to area R102 in FIG7(b), various icons are displayed in a light color with no selectable options. Furthermore, a stain detection icon is displayed in area R300 of the display screen W300. Here, for example, when a copying operation accompanied by paper feeding has ended, and the control unit 100 determines that the sensor needs cleaning, the control unit 100 may also display... Figure 7The display screen W104 of (c) serves as the cover opening / closing request screen.

[0087] In this embodiment, the control unit 100 displays a stain detection icon on the display unit 140 during job execution to notify the user that stains have been detected on the sensor. However, for example, the user can also select the stain detection icon to display a cleaning method for the sensor 16a. As an example, if the user selects the stain detection icon during job execution, the control unit 100, for example, performs a process to temporarily interrupt the copying job. Then, the control unit 100 can, for example, display a cover opening / closing request screen on the display unit 140 when the copying job has stopped and the cover 12 is in an openable / closable state. Alternatively, the control unit 100 can also perform a process without temporarily interrupting the copying job. If the user selects the stain detection icon during job execution, for example, the control unit 100 displays a display screen on the display unit 140 and displays a message such as "The sensor needs cleaning. Please open and close the back cover after printing. Clean by opening and closing the cover."

[0088] In this way, even if the control unit 100 determines that the sensor needs cleaning, and the cover 12 is in a state that cannot be opened or closed during the execution of the copying operation, the control unit 100 will suppress the display of the cover opening / closing request screen, and instead overlay a contamination detection icon different from the cover opening / closing request screen on the display screen. By displaying the contamination detection icon even when the cover 12 can be opened or closed, the user can be made aware that the sensor 16a needs cleaning without interfering with the execution of the operation.
