4.1.20. Software Download (Function 12)
Instead of replacing EPROMs to update the machine’s software, use this pro-
cedure to update the software in the machine’s Flash ROM.
This procedure copies software from an external medium to the Flash ROM
on the machine’s MFCE. The external medium for the new software can be
an MFCE or an EPROM board.
1. Turn off the machine.
2. Insert the Flash/SRAM Copy Tool [A] into the lower IC card slot [B], then
connect the MFCE [C] or EPROM board [D] with new software to the op-
posite side of the tool.

CAUTION
If the machine has an optional Function Upgrade card or an optional
Fax On Demand card, follow the instructions in section 4.1.23.
Otherwise, the programmed data in the IC card may all be erased.
Note:
The switch [E] on the tool [A] must be at the ON position.
The EPROM board uses four 4Mbit EPROMs. Each EPROM must meet the following
specifications.
Size: 4 Mbits
Data width: 8 bits
Number of pins: 32
Access speed: Faster than 150 ns
Socket 1: ROM0, D15 - D8 Socket 2: ROM1, D15 - D8
Socket 3: ROM0, D7 - D0 Socket 4, ROM1, D7 - D0
