2 How the iR-M1 Operates
The iR-M1 enables the customer to access the copier through the network and use it to
print files using advanced spooling and job control functions. Users can print to the iR-M1
from networked PCs, Mac OS computers, and UNIX workstations running TCP/IP. In addi-
tion, the iR-M1 parallel port can be used to print directly from a connected PC.
The iR-M1 custom-designed boards and system software are responsible for efficient im-
age processing and printing controls. The main functions of iR-M1 components and soft-
ware are described below.
The iR-M1 uses a specialized motherboard to process image data for printing images. The
motherboard includes a Intel Mobile Pentium III 500MHz CPU. The PostScript Interpreter
interprets the page description file. The RipChip ™ on the motherboard controls data man-
agement and other system functions, freeing up the CPU for efficient image data processing.
High-speed DIMMs (dual in-line memory modules) on the motherboard hold the image
data during printing. The iR-M1 is originally configured for a minimum of 128MB of
memory.
