Abstract
A temperature control system for an ink jet printer has a plurality of head units each having a heater and a temperature sensor, and a fan for cooling the plurality of head units in which the fan has a heat transfer coefficient represented by a gradient of a first line connecting a maximum heat generated by heads corresponding to a sum of heat generated by the head units and heat generated by said heaters and a maximum operable temperature of said printer, and said heaters each has a heat transfer coefficient represented by a gradient of a second line connecting said maximum heat generated by the heads and a minimum operable temperature of the printer.
