There ya go MP130 up and running again.How do you empty the waste ink absorber in the canon pixma mp130?
I've used 99% Isopropyl Alcohol in some. Is this a sponge or just a cup like absorber? For the sponge I usually remove it and soak it in alcohol and then, wearing rubber gloves, squeeze out the ink/alcohol mixture (multiple times if needed) for the cup type, I just use Q-tips to remove what I can and then clean the surface with Alcohol.
