Abstract
A printer has one or more fans in the vicinity of a fixing device to blow air directly onto a continuous form when printing is stopped and when rollers in the fixing device are separated. The fan or fans can be provided on a pressure roller side of the continuous form, in which case the continuous form shields a heat roller from the air flow of the fans. In the alternative, the fan or fans can be on the heat roller side, in which case a shield extending along the circumference of the heat roller, duct, or both is used to protect the heat roller from the air flow and/or the continuous form from direct heat radiation. A pair of rollers are disposed downstream of the fixing device and are rotated while the continuous form is stopped so as to maintain tension on the continuous form.
