Firmware

Firmware is a category of memory chips that hold their
content without electrical power and include ROM, PROM,
EPROM and EEPROM technologies. Firmware becomes
“hard software” when holding program code.

This “hard software” is kept in semi-permanent memory. It
will not be forgotten when the power is shut off. Firmware
programs can be altered, and are frequently revised.

An EPROM is typically erased by using intense ultraviolet
light.

Identifying Your Current Firmware Version

You may be asked for the firmware version number if you call
for service. Your Authorized OKIDATA Service Dealer will
work with you to identify the firmware version of your fax
machine.

Upgrading Your Firmware

Consult the store location where you purchased your fax
machine, or call 1-800-654-3282 (1-800-OKIDATA) for the
location of the nearest Authorized OKIDATA Service Dealer.

Serial Number of Your Fax Machine

The serial number of your fax machine is on a label on the
side or back of your fax machine.

The label will say “S/N”.

An example serial number is: 401A0154693.
