Before replacement of the logic board ass'y, check the ink absorber counter value (by
service test print or EEPROM information print). If the counter value is 7% or more,
also replace the ink absorber kit when replacing the logic board ass'y. If the counter
value is less than 7%, register the current ink absorber counter value to the replaced new
logic board instead.
