Ink Absorber Life Estimation; Power Supply Unit And Modular Board Replacement - Canon PIXMA MX870 Service Manual

(6) Ink absorber life estimation

For your reference in servicing, the estimated number of months until the ink absorber will become full is given in EEPROM
information print.
Sample: DF = 00049 (It indicates that there will be 49 months before the ink absorber becomes full.)
Note 1: In the following cases, estimatino of the ink absorber life will not be properly given:
- The printer is not connected to a computer.
- The time is not properly set in the computer.
- The ink absorber counter has been reset (to zero) before.
Reason: The ink absorber life is calculated using data of the printer installation date and the current ink
counter value. Data of the printer installation date is updated when the printer is connected to a
computer.
Note 2: The ink absorber life is calculated based on the user's usage (frequency of printing, printed items, etc.)
before EEPROM information print (i.e. before repair servicing). It will vary according to the user's usage
after EEPROM information print (i.e. after repair servicing).
