Printing Eeprom Information - Canon BJC-820 Service Manual

Part 3: OPERATION

2.3 Printing EEPROM Information

The EEPROM stores such information as function settings, control ROM version, total
number of sheets passed, total waste ink absorbed, and records the last user-
unrecoverable error. The information stored in the EEPROM is printed out in the
EEPROM information print. The same data as written in the service test print is written
at the header. The EEPROM information is especially useful for determining how
heavily the printer has been used.
