The EEPROM is attached onto the logic board by a socket which makes replacement relatively simple When replacing the EEPROM though do not bend or deform the EEPROM pins or subject the EEPROM to static electricity We recommend wearing wrist straps to discharge static electricity and using the ROM extractor to remove the EEPROM After you have replaced the logic board perform EEPROM list print refer to Part 3 3 4 2 Service mode page 3 24 to check the EEPROM data settings That is check that there is no major discrepancy between the waste ink level waste ink optimizer level device IDs information for detecting remaining ink level number of sheets fed and other printing data compared with the actual state of the absorbers and conditions of use 4 3 2 EEPROM replacement We recommend replacing the logic board if the printer is used frequently or you doubt the integrity of EEPROM data settings However in this case you must replace the waste ink absorbers refer to Part 5 4 4 Waste Ink Absorber page 5 10 and initialize the EEPROM For details see Part 3 3 4 2 Service mode page 3 24 After that perform EEPROM list print and confirm the contents of EEPROM data EEPROM Figure 5 9 EEPROM 5 9 Part 5 Maintenance BJC 8500 4 4 Waste Ink Absorber Replacement When the waste ink warning waste ink tank full error occurs and the waste ink absorbers waste ink optimizer absorber are replaced be sure to replace all ei
