CHAPTER 3 ARRANGEMENT AND FUNCTIONS OF ELECTRICAL PARTS
I. Upgrading
The machine may be upgraded in either of the following two ways:
•
By replacing the DIMM on the image processor PCB.
•
By updating the DIMM contents through downloading from a computer.
1. Replacing the DIMM
The DIMM (flash ROM) used in the machine comes in two types; both types are mounted on
the image processor PCB. Figure 3-12 shows a view in which the IP small cover has been removed:
•
DIMM for the IP-CPU
4 MB: bottom of 2-layer slot
1 MB: top of 2-layer slot
•
DC-CPU DIMM (1 MB)
