4.2.2 Uploading and Downloading EEPROM Data
When the main control board is replaced, EEPROM data must be reflected on a new main control
board. Use “EEPROM Operations” in the option tab of the maintenance utility to reflect EEPROM
data on the new main control board. (See Figure 4-4.)
Reflect EEPROM data on the new main control board in the following procedures:
(1) Check that the printer and PC are connected by the parallel I/F, then execute the
maintenance utility.
(2) Click the "Option" button in "Main Menu Dialog".
(3) Click the “Upload” button (Upload EEPROM Data) in “EEPROM Operations.” (EEPROM
data read is completed.)
(4) The read EEPROM data is displayed in “Dialog” of the maintenance driver.
(5) Leave the display of the maintenance driver as is and replace the main control board.
(6) Click the “Download” button (Download EEPROM Data) in “EEPROM Operations”. (EEPROM
data write is completed.)
Depending on the level of a main control board failure (parallel I/O failure, etc.), however,
EEPROM data may be unable to be uploaded.
In such a case, use the maintenance utility to perform the following adjustment after replacing the
main control board:
• Setting the LED head drive time (Section 4.2.1)
• Setting the LED head count (OKIPAGE 8
z only)
• Setting specifications (ODA/OEL/INT-A/INT-L)
