1. A base device to support a finisher comprising:
a base pan including a section being in a form of a protrusion which protrudes outward from a first side of the base pan;
a first plurality of casters coupled to the base pan to contact a surface while the base pan is level with respect to the surface, each of the first plurality of casters being beside a respective separate corner of the base pan and at least two of the first plurality of casters being beside the protrusion as the section of the base pan;
a second plurality of casters coupled to the protrusion as the section of the base pan, to be positioned above the surface while the base pan is level with respect to the surface and to contact the surface while the base pan is inclined to a first degree of tilt with respect to the surface, each of the second plurality of casters having a diameter smaller than a diameter of each of the first plurality of casters; and
a recess, between at least two of the second plurality of casters, to receive a tip foot, the tip foot arranged to:
contact the surface while the base pan is inclined to a second degree of tilt with respect to the surface, the second degree of tilt being different than the first degree of tilt; and
be positioned above the surface while the base pan is, with respect to the surface, level or inclined below the second degree of tilt.
