4.2.3 Uploading and Downloading EEPROM Data
When the main control board is replaced, data from the old EEPROM must be loaded into the EEPROM on the new
board. Use EEPROM Operations in the option tab of the maintenance utility to download EEPROM data onto the new
main control board. (See Figure 4-4.)
Download EEPROM data onto the new main control board in the following procedures:
(1) Check that the printer and PC are connected by the parallel I/F, then run 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 (See Section 4.2.1 above)
- Setting the LED head dot count (See Section 4.2.2 above)
- Setting specifications (ODA/OEL/INT-A/INT-L)
