Abstract (en)

[origin: EP1156395A2] The roller (FR) is heated by a central heater (H1) and cooled by a fan (BL), air being directed to and from the roller by guides (AG1,AG2). With heater at maximum power the roller surface temperature is raised to a set value (Stand-by temperature). When a fixing operation is about to be performed the temperature is lowered by cooling with the fan at moderate output (preparation period) and finally reduced to the fixing temperature by raising the fan output.
