Specific screw location (photos are from the MG5200 series):
When the paper separation slope is removed as well as the printer unit from the bottom case, ink
absorbers can be replaced. Some of the ink absorbers are under the paper separation slope.
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.]
