Accessing Life Counters From Engine EEPROM
Life Counters Overview
This section of the Technical Manual is to instruct you on how to access the Life Counters found in the
Engine EEPROM. The data contained in the Life Counters can be very a useful troubleshooting tool.
Typically, when the printer display (LCD) shows an error message, the technician will take the appropriate
action to correct the discrepancy. However, if the technician suspects an erroneous error message, the
technician should collect the current data from the Life Counters, run the printer through several print
cycles, then check the Life Counters again to make sure that the MCU PWB is correctly collecting the data.
The improper collection of data would indicate a bad MCU PWB. The following Life Counters are included
in the Engine EEPROM:
1. OPC/Xerographic Cartridge
2. Yellow Toner Accumulative Dispense Time
3. MegentaToner Accumulative Dispense Time
4. Cyan Toner Accumulative Dispense Time

7. Fuser Unit Accumulative Images Processed
8. 2nd Bias Transfer Roller Assembly
