● Mechanism
MEAP platform judges whether MEAP applications can be operated on it using on the 2
information below:
• Device Specification ID
• MEAP Specifications
Device Specification ID shows information such as the original functions of MFP (including
print, scan, and copy), and one that differs by model such as maximum copy number,
thus each model has a different ID. (It is easy to determine the IDs for this reason.) MEAP
application declares 1 or more Device Specification ID required for its execution. Declaration
of multiple Device Specification IDs means that the application is operable in all the models
declared. Upon installation of MEAP application in (using) SMS or MEAP Enterprise Service
Manager, matching of Device Specification ID is executed on the side of MEAP platform
machine. The machine which doesn't support the ID declared by the application rejects
installation of such an application.
Meanwhile, MEAP Specifications shows other information than defined by Device
Specification ID above, including network and security. Thus each model does not always
have the same version.
