When printing is needed, the information is stored in the first memory unit 304 for subsequent printing processing; when output to an external device is required, the scanned image is stored in the first storage section 303, and the user calls the scanned image from the first storage section 303 again when required and outputs the scanned image to the external device.
In addition, when a document is printed in color or in large volume, the first storage unit 303 may serve as a buffer, thereby relieving the pressure of the main control system 301, preventing printing pauses, and ensuring printing speed.
In a possible implementation manner, the main control system 301 may further include a unit module and the like related to performing other functional operations, for example, a power management unit may be included for power supply of the main control system 301 or power supply to the sub-control systems; also, for example, a temperature detection unit may be included for realizing that the main control system 301 obtains temperature information inside the image forming apparatus or environmental information outside the image forming apparatus.

The first memory unit 304 may be a DDR (Double Data Rate) SDRAM (synchronous dynamic random access memory), an SDRAM (synchronous dynamic random access memory), or the like. An external device connected to the image forming apparatus is connected through the interface unit 306, and the interface unit 306 may be a wired manner, for example: the wired mode includes but is not limited to Universal Serial Bus (USB) mode; as another alternative, the interface unit 306 may also be wireless, for example: wireless modes include, but are not limited to, Wireless Local Area Networks (WLAN), Bluetooth (BT), Near Field Communication (NFC), and Infrared (IR).
Referring to fig. 4, a functional unit diagram of a sub-control system of an image forming apparatus according to an embodiment of the present invention is shown. The sub-control system 401 includes a sub-control unit 402, a second storage unit 403, and a second memory unit 404.
The sub-control unit 402 controls the scan control unit to perform control of the scanning unit to perform an image scanning operation. Specifically, the image scanning operation is that the scanning control unit controls and starts the scanning motor according to the control instruction issued by the sub-control unit 402, and drives the scanning unit to read the original image. The scanning control unit also comprises position detection for controlling the position sensor to detect the position of the scanning unit, the width of paper, the cover opening detection, the ADF paper feeding detection and the like.
In a possible implementation manner, the sub-control system 401 may further include a unit module and the like for performing other functional operations, for example, a power management unit may be included for power supply of the sub-control system. Similarly, the sub-control system 401 may further include related unit modules for executing other functional operations, which are not described herein again, and the unit modules included in the sub-control system 401 are not limited in this embodiment of the present invention.
In one possible implementation, the second storage unit 403 may be a Solid-State memory (abbreviated eMMC, Embedded Multi Media Card), a Solid-State Hard Disk (abbreviated SSD, Solid State Disk or Solid State Drive), or a Hybrid Hard Disk (abbreviated HDD, HHD: Hybrid Hard Disk), etc. The first memory unit 404 may be a DDR (Double Data Rate SDRAM), an SDRAM (synchronous dynamic random access memory), or the like.
After the scanning unit reads the image, the image is sent to the second storage unit 403 of the sub-control system 401 for storage, and the second memory unit 404 is called for image processing. The image processed image is converted directly into a scan file that the main control system can recognize and print or output to an external device. Wherein the image processing comprises: image pixel enhancement, image pixel print data processing, front-end correction, image compression.
The sub-control system 401 has the second memory unit 404 and the memory bandwidth thereof, and performs image pre-processing on the scanned image through the sub-control system 401, and converts the image into a scanned file which can be recognized and printed or output to an external device by the main control system.
Referring to fig. 5, a schematic structural diagram of another image forming apparatus according to an embodiment of the present invention is shown. The image forming apparatus 500 further includes a print engine control unit 507, a print unit 508. The print engine control unit 507 is directly connected to the main control system 501 and is isolated from the sub control system 502 by the main control system 501, and when the sub control system 502 is powered off or damaged, the main control system 501 can continue to control the print engine control unit 507 to process image data to be printed. In other words, when the sub-control system 502 is powered off or damaged, the main control system 501 transmits print data to the print engine control unit 507, and the print engine control unit 507 controls the print unit 508 to perform a printing operation.
Specifically, as shown in fig. 5, the image forming apparatus 500 includes a main control system 501, a sub-control system 502, a scan control unit 503, a scan unit 504, a control panel 505, a print engine control unit 507, and a print unit 508. Among them, a main control System 501, for example, an SoC (System on Chip), is configured as a central processing unit of the image forming apparatus 500, and receives a panel operation instruction from the control panel 505 or a scan control command from an external input. The sub-control System 502, for example, a System on Chip (SoC), receives the scan start instruction transmitted from the main control System 501, and based on the scan start instruction, outputs a control instruction that controls the scan control unit 503 to be able to execute an operation of controlling the scan unit 504 to perform image scanning. Among other things, the sub-control system 502 also receives the scanned image output by the scanning unit 504 and converts the scanned image into a scanned file that the main control system 501 can recognize and print or output to the external device 506. When it is necessary to perform a printing operation on a scanned image, the main control system 501 transmits print data to the print engine control unit 507, and the print engine control unit 507 controls the print unit 508 to perform the printing operation. In addition, when the sub-control system 502 is powered off or damaged, since the print engine control unit 507 is isolated from the sub-control system 502 by the main control system 501, the main control system 501 can continue to control the print engine control unit 507 to process image data to be printed. In other words, when the sub-control system 502 is powered off or damaged, the printing operation of the user is not affected.
In a possible implementation manner, the main control system 501 sends the print data to the print engine control unit 507 and stores the print data in the storage unit of the main control system 501, and when copying copy by copy or copying page by page, the main control system performs the printing operation while performing the scanning operation, so that the image forming speed time can be shortened, and the multifunctional all-in-one printer is beneficial to processing high-speed printing and scanning transactions in parallel.
Referring to fig. 6, a schematic view of a processing flow for determining power failure or damage of a sub-control system according to an embodiment of the present invention is shown. The judgment processing flow of the power failure or damage of the sub-control system is as follows: step S601, the main control system judges whether the sub-control system is powered off or damaged according to the feedback information provided by the sub-control system. In step S602, if the sub-control system is powered off or damaged, the main control system notifies the operation panel or the external device to prompt the user of "scan system failure without affecting the printing operation", or prompts the scan system failure in other forms, but may also perform the printing operation, for example, the image forming apparatus without the operation panel may indicate one or more of lighting, lights with different colors, the number of times or the time duration of the lights flashing, and the like. In step S603, the print engine control unit processes the data to be printed according to the user instruction. The user command is a printing control command, and the data to be printed may be the data to be printed which is already stored in the first storage unit, or may be a print task newly issued to the main control system by the user. In step S604, if the sub-control system is not powered off or damaged, the sub-control system can perform a scanning operation normally. In step S605, the scan control unit scans the document image according to a user instruction. In step S606, when the user issues an operation instruction for copying or an operation instruction for printing the stored scanned document image, the process proceeds to step S603. In step S603, the print engine control unit processes the data to be printed according to the user instruction. If the user does not issue an operation instruction for copying or an operation instruction for printing the stored scanned document image, the flow is ended.
Referring to fig. 7, a schematic structural diagram of another image forming apparatus 700 according to an embodiment of the present invention is shown. The image forming apparatus 700 may include at least two sub-control systems. The sub-control systems may be specifically socs (System on Chip), and the two sub-control systems may be the same or different. The first sub-control system 702 controls the first scanning unit 704 to execute a first image scanning operation through the first scanning control unit 703, the second sub-control system 707 controls the second scanning unit 709 to execute a second image scanning operation through the second scanning control unit 708, the first sub-control system 702 and the second sub-control system 707 are respectively electrically connected with the main control system 701, the first scanning control unit 703 is connected with the first sub-control system 702, and the second scanning control unit 708 is connected with the second sub-control system 707.
The first scan control unit 703 is a first scan engine control unit that reads a first side of the document image in accordance with a control instruction of an image scanning operation to obtain a first scanned image. The second scan control unit 708 is a second scan engine control unit that reads the second side of the original image in accordance with the control instruction of the image scanning operation to obtain a second scanned image.
In one possible implementation, the first sub-control system 702 controls the first scan control unit 703 to perform a first image scanning operation; meanwhile, the second sub-control system 707 controls the second scan control unit 708 to perform a second image scanning operation.
Specifically, when a user issues a panel operation instruction or a control command for double-sided scanning or double-sided copying from the control panel 705 or through the external device 706, the main control system 701 controls the first sub-control system 702 and the second sub-control system 707 to perform an image scanning operation at the same time. The first sub-control system 702 controls the first scanning unit 704 to read the first side of the document image in accordance with a control instruction of the image scanning operation through the first scan engine control unit 703. Meanwhile, the second sub-control system 707 is controlled to control the second scanning unit 709 to read the second side of the original image according to a control instruction of the image scanning operation through the second scan engine control unit 708. After the scanning is completed, the first sub-control system 702 receives the first side of the document image, that is, the first scanned image, and the first sub-control system 702 performs image processing on the first scanned image. Meanwhile, the second sub-control system 707 receives the second side of the original image, i.e., the second scanned image, and the second sub-control system 707 performs image processing on the second scanned image. Then, the first sub-control system 702 transmits the first scanned image to the main control system 701, and at the same time, the second sub-control system 707 transmits the second scanned image to the main control system 701. The main control system 701 performs front-back sequencing on the received first scanned image and second scanned image to form a scanned file or sends the scanned file to a print engine control unit for printing operation.
In addition, when single-side scanning is required, that is, when a user issues a single-side scanning or single-side copying panel operation instruction or control command from the control panel 705 or through the external device 706, the main control system 701 may control only one of the sub-control systems to perform an image scanning operation, such as: only the first sub-control system 702 is controlled to control the first scanning unit 704 to read a single-sided image of the original through the first scan engine control unit 703 according to a control instruction of the image scanning operation; or only the second sub-control system 707 controls the second scanning unit 709 to read the single-sided image of the original in accordance with a control instruction of the image scanning operation through the second scan engine control unit 708.
