No. There are purely physical, "physiophysical", processes and psychophysical processes, the latter of which are as causally potent as the former. Experiences are psychophysical organismic processes, which have both a subjective and an objective aspect. They are causes, but not in virtue of their mental properties but in virtue of their physical properties. Qualia do not equip experiences with additional nonphysical powers.

This is an example of a conscious activity (reading a manual), that is used to support the idea that conscious activities are epiphenomenal. It is therefor not a valid example since it is begging the question ("conscious activities are epiphenomenal, because this conscious activity is epiphenomenal").
I'm not saying that conscious activities are epiphenomenal but that their nonepiphenomenality is solely due to the physical powers involved, because phenomenal qualities, in short qualia, are causally powerless.
So, strictly speaking, it's not the felt painfulness of a pain that makes me cry, but the corresponding physiological intensity of the pain experience.
