Installation
• DSDK applications are installed via Type 1 or Type 2 SD cards into partitions and directories in the
MFP/LP HDD or SD card itself that are specifically allocated for DSDK applications.
• The SAS (SDK Application Service) in the MPF contains an installer for DSDK applications. When
the main power is turned ON, the SDK installer inside the SAS checks the pre-defined area in the
SD card for the necessary installation files and then performs the installation. For more details on
the authentication process performed at installation, see Authentication of SDK Applications at
Installation below.
• (MFP models only): Type 2 applications can be further divided into Xlet applications and Servelet
applications. Xlet applications have the capability of displaying their own screens on the MFP/LP
operation panel, whereas Servelet applications do not.
• (MFP models only): A maximum of three Type 1 applications can be installed on the MFP/LP at
one time, depending on the amount of virtual memory (VM) that the applications require. As
mentioned above, the GW system regards the CVM Java core itself as a single Type 1 application.
Therefore if one Xlet and one Servelet application are installed at the same time, the MFP/LP will
allow one additional Type 1 application to be installed (see Fig. 2 below).
• (MFP models only): A maximum of twenty applications can be installed on the MFP/LP at any one
time (total combination of Xlet and Servelet applications), depending on the total amount of VM that
the applications require.
