@Remote
Overview of @Remote Operations
• “@Remote” refers to a remote machine management service that manages and monitors the
MFP/LP status from a remote location called the @Remote Center. Information and commands are
exchanged directly between the MFP/LP and @Remote Center, or between these two points via an
intermediary device called RC Gate, which is connected to the MFP/LP in the same LAN.
• When communicating as a “client”, the MFP/LP continually monitors its own status and informs RC
Gate or @Remote Center when action is required, such as when parts have reached their periodic
replacement limit or an abnormal machine condition is detected. When communicating as a
“server”, the MFP/LP receives requests from RC Gate or @Remote Center for status information
such as the amount of toner remaining in the MFP, after which it provides this information to
whichever device has requested it.
• @Remote communication to and from the MFP/LP is only possible when the relevant SP mode
switch has been turned ON. It is therefore possible to prohibit communication with RC Gate or
@Remote Center by turning this switch OFF.
Data Flow
• The communication protocol used is different depending on whether the MFP/LP is communicating
with the @Remote center directly, or via the RC Gate. The NRS module controls all primary
@Remote functions inside the MFP/LP.
Communicating with the @Remote Center via RC Gate
When the MFP/LP communicates with RC Gate as a client (e.g. notifying the center of a
malfunction)
When the SCS detects an abnormal condition in the MFP/LP or other status-related notification, it
will notify the NRS module. After this, the NRS module obtains more detailed information via the
SCS and then converts it into a special format for transmission to the @Remote Center. Finally,
the data is sent to RC Gate via the NCS module, and then on to the @Remote Center.
