and peripheral equipment. The architecture is based on Java (J2ME, i.e., Java 2 Platform Micro Edition), and is designed to enable the execution of Java

applications.

A MEAP application behaves independently from its host printer's system software, and may be installed or uninstalled using SMS (Service Management

Service), which is an interface that runs as part of the browser on a PC. As long as the device supports MEAP, most MEAP applications may be added to

the device in the field.

11.1.2 MEAP Counter

In addition to the commonly found print counters, a device that supports MEAP is equipped with a counter mechanism used to keep track of which

functions are used as well as how often they are used for individual MEAP applications that are installed. The MEAP counter readings may be checked by

making the following selections on the device control panel: Counter Check Key>MEAP Counter Check. A device may possess the following MEAP

counters, and which counter to use and, therefore, to display all depend on the application in question.

A counter reading may be of a type that is forced to increase as a job is expected or of a type that is increased when the application sends instructions; or,

it may be of a type that increases independently of the host device, thus increasing solely in response to the application being run; specifics are as follows:

Type

forced

in response to instructions from application

application-independent

MEMO:

forced: the device forces the counter to increase its reading in response to execution of a job.

in response to instructions from application: the counter increases its reading only in response to instructions from the application.

application independent: the counter operates according to the specifications of the application.

11.1.3 Construction of the MEAP Platform

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
