Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a comestible loader with flatteners that pivot and translate. One of the methods includes receiving, by a comestible loader, a comestible through an opening defined in a loader frame of the comestible loader and onto a surface; and pivoting and translating a first flattener and a second flattener to a pre-press position to permit the first flattener and the second flattener to position the comestible approximately at a target position on the surface.
