        Software Specifications

        image

        A software package consisting of the Android Firmware and the manufacturer’s own pre-installed applications is installed on the Smart Operation Panel.


        The following three types of software are installed on the Smart Operation Panel.

        1. Android Firmware (Android OS)

        2. Pre-installed applications

        3. Applications that can be installed additionally

          Android Firmware (Android OS)

          The Android Firmware (Android OS) consists of the following modules that are called “stacks”.

          • Linux kernel

          • Android Runtime

          • Library

          • Application Framework

            Pre-installed applications

            On the Smart Operation Panel, applications such as the GW applications (Copy/Printer/Document Server/Scanner/Fax), Control Panel Browser, the standard keyboard, Installer, Gallery, Self Check are pre-installed. Unlike those installed on the controller board of the MFP, GW applications that are installed on the Smart Operation Panel are for controlling operation and display of the Smart Operation Panel.

            Pre-installed applications are provided as part of the control panel firmware (Cheetah System) together with the Android firmware. When you update the control panel firmware using the recovery mode or another method, the pre-installed applications will also be updated.

            Applications that can be installed

            On the Smart Operation Panel, applications can be installed in addition to the pre-installed applications.

            Applications that can be installed include optional applications that customers can purchase, applications that are installed only on machines sold in specific regions, and custom-made applications.

            On an MFP, applications such as Simple UI applications (Quick Copy, Quick Fax, and Quick Scanner) and Scan to Me are installed.


            Communication specifications

            The Smart Operation Panel and the GW controller are connected by a USB 2.0 cable. They communicate with each other via the Android OS on the Smart Operation Panel, using protocols called “OCS Library” and “Flair-API (System/Application)”.

            System block diagram

            image

            Overview of Components


            Communication module/signal name


            Details


            OCS Library

            OSC stands for Operating Control Service. It is a module that controls the control panel. The set of signals used by this module to control the control panel are called the OCS Library. It is used during communication between the Legacy UI (system) module on the Smart Operation Panel and the GW module for the following processes.


            Flair-API (System/Application)

            Flair is the manufacturer's own communication interface between software modules. The interface uses a generic WebAPI.

            It is divided into two parts: a part that communicates directly with applications such as the application manager, Home, Authentication, Banner, Check Status, and Widgets, and a part that monitors applications. It communicates with the GW controller via the CATS module.


            CATS

            CATS stands for Cheetah Application Total System. It is a module in the GW controller.

            Because the Smart Operation Panel uses the Android OS, the contents and protocols of communication are not the same as those of the conventional control panel. CATS serves as an intermediary between the GW controller and the Smart Operation Panel.

            It also controls the power status of the control panel.

            CATS communicates with the Smart Operation Panel using the Flair-API, and communicates with the GW module using the GW-API.


            GW-IPC

            The name of the interface used among modules in the GW controller. The role is the same as that of the Flair-API.

            • Deciding on the display format suitable for a particular model of the control panel, so that the intended image data can be converted to actual image data.

            • Converting touch panel operations to commands.

            image


          • API stands for Application Programming Interface. An API is an interface that software modules use in order to communicate with each other.


        Application Specifications

        The pre-installed applications and applications that can be additionally installed on the Smart Operation Panel can be classified into the following 3 categories.

        • System applications

          Applications that operate in conjunction with multiple functions (operating regardless of the application)

        • Program applications

          Applications that provide a single additional function

      3. ELECTRICAL COMPONENTS


        image


        • The CPU board has a CPU, memory, and a flash drive.

        • The Microcomputer board has various interfaces, Wi-Fi module and other devices.


          Touch panel

          The touch panel of this machine uses a 4-wire resistive film method (low load resistive film analog 4-wire method). It can detect two points for flick/drag/pinch-in/pinch-out operations. Resistive touch panel has been adopted in order to allow operation with a prosthetic hand.

          Basic Structure

          An analog 4-wire resistive film touch panel has 2 layers. Two materials (mainly film or glass) with transparent conductive film (ITO) are attached such that the transparent conductive film layers face each other.

          When the film is pressed with a finger or a pen, the transparent conductive films contact each other and the touch panel operation is recognized.

          Insulators (spacing dots) secure space between the two transparent conductive film layers to prevent short-circuiting.

          Because the transparent conductive film has a uniform resistance characteristic, the resistance value reflects the distance of contact.

          Self-Check (multi-touch calibration) mechanism

          With the Multi-touch calibration in the self-check function, the touch panel is automatically calibrated using the results of touches to the top left and bottom right positions.

          The values of “EVR_X”, “EVR_Y”, “X_MAX”, and “Y_MAX” are used for internal processing. They do not indicate the positions or distance of the touched points. There is no problem unless there is a huge difference between the values of the first calibration and the second calibration.

    2. CONTROLLING THE POWER SUPPLY


      1. EXITING ENERGY SAVING MODES

        Because this model of Smart Operation Panel has no hardware keys, the MFP exits from energy saving mode when the user does one of the following:

        • Touches the display panel

        • Lifts the ADF

        • Sets an original in the ADF


      2. SCREEN STARTUP MODE


        Startup Modes

        There are two screen startup modes. The factory default setting is Normal.

        1. Normal

          This is the standard startup mode. When the main power of the MFP is turned ON, the control panel starts up using less power compared to Quick mode.

        2. Quick

          By preparing for the next startup when the machine shuts down, the control panel starts up faster than in Normal mode.


          Changing the Screen Startup Mode

          Screen Startup Mode can be changed in Screen Features.

          image

          Select [Screen Features] > [SYSTEM] > [Screen Device Settings] > [Screen Startup Mode], and then select [Normal] or [Quick].

          • In the following cases, the control panel starts up in Normal mode even if [Quick] is selected.

            • The power cord has been disconnected from the power outlet after the last shutdown.

            • The MFP is turned ON after being turned OFF due to reasons such as a power failure.

            • The MFP was not properly shut down the last time it was turned OFF.


              How the Control Panel Starts Up

              In Normal mode

              The startup screen is displayed on the display panel, followed by the startup animation.

              image

              In Quick mode

              The [Home] screen is displayed immediately after the main power of the MFP is turned ON. The startup screen displayed when starting in Normal mode is not displayed.

              How the Screen Shuts Down When Quick mode Is Selected

              When Quick mode is selected, the MFP prepares for the next startup when it shuts down The main power indicator flashes during preparation for the next startup. The indicator turns off when preparation is completed.


              image


              If the MFP is turned ON during shutdown, the preparation for the next startup continues. When preparation for the next startup is completed, the control panel starts up in Quick mode.

          • When Quick mode is selected, the control panel starts up faster than in Normal mode but shutdown takes longer than in Normal mode.

      3. SHUTDOWN FUNCTIONS

The shutdown functions and their uses are as follows.


Shutdown mode

Use

Operation


Normal Shutdown


Same as shutdown by users.

Turn the main power switch off.


Forced shutdown

When normal shutdown does not complete even though you waited a long time.


Hold the main power switch 6 seconds or longer.


Shutdown for parts replacement

  • When you have to disconnect the power cord from the power outlet, such as when replacing parts.

  • When you want to start the machine normally and then enter recovery mode, without changing the Startup mode in Screen Features. (For updating control panel firmware)


Turn the main power switch off while holding down [Stop].


Shutdown for software update

When you are going to turn on the MFP within 5 minutes for updating the MFP firmware or package.

(Use shutdown for parts replacement if you are updating the control panel firmware.)


Turn the main power switch off while holding down the [EX1] key.

Normal Shutdown

The MFP is equipped with a function to shut down safely in order to:
