SCS (System Control Service) Manages the status of all internal operations performed on or by the
system as a whole, and controls the switching of the LCD screen as
well as the operational link between SP settings and machine
operations.
SRM (System Resource
Manager)
In addition to managing hardware resources, this module mediates
control of the printer engine, scanner engine and memory resources
during the image creation process.
DCS (Delivery Control Service) Controls all non-FAX transmission/reception of e-mail as well ass the
forwarding of image data to servers and folders.
MIRS (Machine Information
Report Service)
Controls the sending of machine configuration settings by e-mail
UCS (User Control Service) Manages the Address Book data.
CCS (Certification Control
Service)
Mediates communication between the principal machine function and
external charge device during the authentication process, as well as
the charge-related processing (e.g. counters).
NRS (New Remote Service) Controls remote correspondence with RC Gate (e.g. diagnostics,
firmware update, settings changes).
LCS (Log Control Service) Controls the MFP/LP’s access logs (e.g. Address Book, Document
Server, MFP/LP functions).
DESS (Data Encryption Security
Service)
Controls the encryption and decryption functions.
1-2-2 Principal Machine Functions
Copier Activates the scanning engine, which reads the original and then sends the data
on to the controller to be printed out from the printing engine. Secondary data,
such as that used for access control, is handled from the operation panel.
Printer Receives image data through the host interface, which then sends the data to the
controller. Also contains a printer language processing subsystem (e.g. RPCS)
that converts the printer language into image data, which is then printed out from
the printing engine. Secondary data is handled via the connection protocols
between the driver UI and the host I/F.
Scanner Activates the scanning engine, which reads the original and then sends the data
to a PC via the host I/F. Scanning can be initiated from both the operation panel
and from a PC via a TWAIN driver.
FAX Activates the scanning engine, which reads the original and then sends the data
to the FCU to be sent as a FAX via a telecommunications line. Also receives FAX
data and prints it out from the printing engine.
