Canon iX6500 Series Service Manual page 22

When the printer unit is separated from the bottom case, ink absorbers can be replaced.
When the ink absorbers are replaced, confirm that the replaced new absorbers fit in place
securely, and they do not lift.
After replacement of the ink absorbers, reset the ink absorber counter value to zero in the
service mode. [See 3-3. Adjustment and Settings in Service Mode, for details.]
