Firmware

Serial Number of Your Fax Machine

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.

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.
