Re: Ricoh mp 7502 please help

if I understand correctly, you mean to make a dump of firmware from a working unit?....if you succeed, you absolutely must let us know how you did it.

That's what I understood him to say also...AND I, too would like to know how to do it. About twenty or twenty-five years ago Ricoh allowed you to do this through their service mode. However, I have not seen a setting that enabled it for a very long time.

At one time one of the means of updating firmware was actually replacing the EEPROM. Even after the introduction of the PCMCIA cards for updates, the EEPROM was still socket mounted. There were also devices available that could write to and read from all types and sizes of ROM, PROM, EPROM and EEPROM devices. You could actually download an image file from Ricoh and use that to write to an EEPROM, erased EPROM or blank PROM.
