<P>PROBLEM TO BE SOLVED: To suitably cool a unit which greatly rises in temperature without increasing fan capacity by distributing air preferentially to a laser unit and a power unit during one-surface printing and to both-sided conveyance paper and CRG units during both-surface printing. <P>SOLUTION: A flapper for air capacity distribution is provided behind an air course of a fan, and its angle is changed in synchronism with both-surface unit conveyance timing by using a solenoid performing both-surface conveyance. <P>COPYRIGHT: (C)2008,JPO&INPIT |
