Preventive Replacement Of Ink Absorber - Canon MX882 Service Manual

(5) Ink absorber counter setting
Before replacement of the logic board, check the ink absorber counter value, and register it to the replaced new
logic board. (The value can be set in 10% increments.)
In addition, according to the "Guideline for Preventive Replacement of Ink Absorber," replace the ink absorber.
When the ink absorber is replaced, reset the applicable ink absorber counter (to 0%). See
Settings in Service Mode.

(6) Preventive replacement of ink absorber

Replace the ink absorber in accordance with the "Guideline for Preventive Replacement of Ink Absorber" even
when the ink absorber is not full. (Related Service Information #Q-12E/J-0188)
< Guideline for preventive replacement of ink absorber >
Replace the ink absorber when it falls in either Criteria 1 or Criteria 2.
Criteria
Criteria 1:
*
The ink absorber life
or less.
Criteria 2:
The ink absorber counter value is
80% or more.
* The estimated number of months until the ink absorber will become full
< How to judge >
Print the EEPROM information, and check the "D" (ink absorber counter) and "DF" (ink absorber life) values.
Step 1: Is "D" 80% or more?
Yes (80% or more) -> Replace the ink absorber.
No (less than 80%) -> Proceed to Step 2.
Step 2: Is "DF" 24 or more?
No (less than 24 months) -> Replace the ink absorber.
Yes (24 months or more) -> No need to replace the ink absorber.
Note: - If the "ST" (installation date) value is 2010/06/30 or earlier, the "DF" (ink absorber life) value
may not be correct. Skip Step 2
- The ink absorber life is an estimated value calculated based on the user's machine usage.
