Construction Of The Meap Platform - Canon iR4570 Series Service Manual

11.3 Construction of the MEAP Platform

iR2270 / iR2870 / iR3570 / iR4570
In addition to the installation of the system software, language file, and RUI, a printer equipped with MEAP functions
calls for the installation of MEAP content, which offers functions (system services) needed to run MEAP
applications and class libraries needed by the MEAP applications to control the device.
It is important that the version of the system software be fully compatible with the version of the MEAP content,
calling for special care. (In the case of a mismatch, the device will not be able to run the MEAP application.) For
version information, refer to the Service Information bulletin that is released in conjunction with the system software.
