● Procedure for reinstalling MEAP applications after replacing the PCB
The following shows the procedure when replacing the PCB.
1) Preparation before replacement
The following work needs to be done before replacing the PCB.
• Some MEAP applications have a function to back up or export the data to be used. If such
a MEAP application is installed, back up or export the data in advance.
• In order to reinstall the applications, copy the licenses (special licenses, reusable licenses,
etc.) of all the MEAP applications to the laptop PC.
2) Replacing the drive
Prepare the necessary service parts, and replace the drive.
3) Reinstalling the MEAP application
When the device has started normally, obtain the jar files of the MEAP applications from the
user, and install them using the license files for reinstallation.
Installation method is the same as normal installation.
4) Importing user information
As necessary, make login service selections and import user information.
Note:
When you replace the PCB without uninstalling MEAP applications, make sure to
reinstall the previously installed applications. Unless reinstalling them, MEAP counter
will not be released and the message "The number of applications that can be installed
has exceeded the limit. Try to install this application after uninstalling other applications."
is displayed so that the installation of new applications may not be accepted. If you
want to install new applications in this case, once reinstall the applications in-stalled
before formatting and uninstall unnecessary applications.
WARNING:
• Do not install a Main PCB of another device and conduct operation check in order
to check whether an error has occurred in the Main PCB. If the PCB is replaced and
the system is started, the data on the installed PCB will be initialized.
• If an application was installed using a license other than reusable licenses and
then installed using a special license for reinstallation, the moved MEAP counter
information is migrated to the application.
• If the serial number is changed due to device replacement, a transfer license needs
to be obtained and installed by a service technician as is the case with iR devices.

■ Actions to be taken when E616 is displayed.

● Overview
When E602 is displayed and then the device is restarted as a remedy, E616 may be
displayed in some cases.
This is a symptom that occurs when the power is cut off without shutdown (such as
disconnecting the plug of the device). The error code is displayed when the file system of the
MEAP storage area is in an abnormal status.
When the device is started, it checks the file system. If the device detects an error, it displays
the error code E602, disables the MEAP function, and then starts.
When the device is restarted according to the remedy for E602, the file system is recovered
automatically in the system. If the recovery procedure succeeds, the device starts normally
with the MEAP function enabled.
However, if the file system could not be recovered by auto recovery, E616 is displayed.
Since the system is automatically formatted when E616 is displayed, the installed MEAP
applications will disappear and the device's MEAP function itself will also be disabled.
For this reason, it is necessary to enable the MEAP function and then reinstall the MEAP
applications.
● Work procedure
Perform the following procedure when E616 is displayed.
1) Start the device in service mode.
2) Select [ Setup ] > [ SERVICE MODE ] > [ FUNCTION GR. ] > [ MEAP FUNCTION ] > On to
enable the MEAP function.
3) Restart the device to start the MEAP function.
4) Access SMS, and then use a reusable license or special license for reinstallation to install
the MEAP application.
Note:
As for MEAP applications that were installed using reusable licenses, the reusable
licenses can be used to reinstall the applications. For other MEAP applications without
reusable licenses, use special license files to reinstall them, in the same as way as
handling a storage drive failure.
For information on how to obtain a special license for reinstallation, see "Special license
for reinstallation" in this chapter. Then contact the support department of the sales
company to have the license issued before starting the work.
5) Start the MEAP application.
