4. Special Notes at Maintenance Service
4.1. Main Board
4.1.1. EEPROM
-When replacing the Main Board
Be sure to remove the EEPROM (IC18) from the socket of the old
Main Board and re-install it on the new one.
-When replacing the EEPROM
If customers have downloaded commercial fonts, some of them cannot be
downloaded again to a replaced new EEPROM (*1).
In those cases, a new master disk of the fonts or a new installation disk
of the fonts is required.
If no commercial fonts are downloaded, the EEPROM can be replaced for
use without any special requirement.
<Information stored in EEPROM>
- Parameters and values used by the PostScript system
- ID number (*1) used at downloading of fonts
No method is available to see, to back up or to recover those information.
*1:
At the first initialization of machine, Adobe PostScript system writes to the EEPROM a value unique to each
machine, based on random numbers, as ID number. Some downloadable commercial fonts use this ID
number to protect downloading to other machines, by recording the ID number in the font installation disk at
the first downloading and by matching it with the one in the EEPROM at every downloading thereafter.
