There are free journals that are financed by an academic association or institution, as well as a government information center. The paid open access Scientific Journal Online needs payment on the behalf of the author. Typically money comes from the author, but it also can normally come from the author's research funding. Journals that take publication fees take some steps to ensure editors who achieve peer review aren't alert of whether the author has requested charge waivers or has been granted, or it is required to ensure every single paper is approved through an editor who has no financial stake within the journal.
