Upgrading; Replacing The Dimm - Canon GP335 Service Manual

VII. 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.
A. 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 14-701 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)
