Note! When the EEPROM (engine control PCB) has been replaced, the service life information
of the belt, toner, IDs, etc., is necessarily cleared. Therefore, be aware that the service
life management is likely to suffer errors until the next time units are replaced. The
counts that are cleared when the EEPROM is replaced are those indicated below.
Since the counts, except for Total Sheets Fed, are cleared when the respective units
are replaced, the errors will be resolved at that point in time.
When the SPI/TBH PCB is replaced, it is necessary for the new replacement PCB to take over the
user-settings that the user has been using to that point, as well as the font install information. For
this, copy the EEPROM by the Maintenance Utility, and set up the CU Serial No. However, if
SERVICE CALL 40 is issued and the old EEPROM cannot be used, use the new PCB, and set the
CU Serial No.(See "Setup of CU Serial Number" ) and check the setup of destination (See "Setup
of destination" ).
Meanwhile, in the case of the TBH PCB, the EEPROM can be swapped directly
setup are not required.
