1. A dyeing system that dyes a resin body, the dyeing system comprising:
a conveyance device configured to convey a conveyance unit receiving the resin body;
a reader configured to read information relating to the conveyance unit;
a dye transfer device including a heater;
a dye fixing device including a laser beam source that is configured to emit a laser beam and a scanning unit that is configured to scan the resin body with the laser beam emitted by the laser beam source; and
a controller configured to perform a dye transfer process and a dye fixing process, wherein
during the dye transfer process, the controller is configured to control the dye transfer device to transfer, onto a surface of the resin body, a dye on a substrate that faces the resin body by heating the dye on the substrate using the heater; and
during the dye fixing process, the controller is configured to:
acquire, based on the information read by the reader, a parameter set for the resin body in accordance with characteristics of the resin body, and
control the dye fixing device to fix the transferred dye into the surface of the resin body by heating the surface of the resin body using the laser beam source and the scanning unit; and
during the dye fixing process, the controller is further configured to control the scanning unit to scan the surface of the resin body with the laser beam emitted from the laser beam source in accordance with the acquired parameter.
