Special Notes On Servicing; Ink Absorber Counter Setting; Preventive Replacement Of Ink Absorber - Canon G1000 Series Service Manual

3-5. Special Notes on Servicing

(1) Ink absorber counter setting

Before replacement of the main PCB ass'y, set the ink absorber counter again.
Check the ink absorber counter value using the "D" value in the EEPROM information, and register it to the
replaced new main PCB ass'y. (The value can be set in 10% increments.)
When the ink absorber is replaced, set the ink absorber counter to 0% for whole replacement, or 30% for
partial replacement. For details, see 3-3, (4) Ink Absorber Counter Setting

(2) Preventive replacement of ink absorber

To maintain a proper replacement frequency and avoid possible accidents such as ink leakage during
returning a printer to its owner, perform the following and replace the ink absorber even before ink
absorber becomes full:
How to judge:
Print the EEPROM information, and check the "D" (ink absorber counter) and the calculated ink absorber
life or the "DL" (ink absorber life) values.
Step 1: Is "D" 80% or more? (to avoid coming-back-to repair due to ink full in a short period of time)
Step 2: Is the ink absorber life 24 or more? (to avoid ink leakage during returning the repaired printer to
its owner)
How to know the ink absorber life:
Use the "DL" value in the EEPROM information.
Note: The ink absorber life is an estimated value calculated based on the user's printer usage.
How to read the EEPROM information print:
Ink absorber counter value (%)
Ink absorber life (months)
Yes (80% or more) ->
No (less than 80%) ->
No (less than 24 months) ->
Yes (24 months or more)
Replace the ink absorber.
Proceed to Step 2.
Replace the ink absorber.
-> No need to replace the ink absorber.
