purpose, use the EEPROM operation on the Option of the Maintenance Utility. (See Fig.
4-4.) To copy follow the steps below.
(1) Be sure to confirm that the printer and the PC are connected with a centronics I/F cable.
Then execute the Maintenance Utility. (Note: Printer driver shall be deinstalled.)
(2) Select the Option on the Maintenance Utility.
(3) Click the "UPLOAD EEPROM" button on the "EEPROM Operations".
(4) The contents of the EEPROM data is displayed on the "DIALOG" of the Maintenance
Utility. The contents of the old EEPROM is now copied into the memory of the PC.
(5) Replace the controller P.C.B. with a new one while it displays the above "DIALOG".
(6) After the replacement, click "Download EEPROM" on the "EEPROM Operations".
EEPROM upload has been completed.
In case of troubles such as centronics I/F failure, etc. EEPROM data may not be uploaded
properly. In such case, it is necessary to adjust the following setitngs manually after the
replacement using the Maintenance Utility.
• LED driver time (See 4.3.1.)
• Factory setting (ODA/OEL/INT-A/INT-L)
