Application Framework
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
main 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.
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 2.0/3.0 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)”.
