Ink-jet type image forming device

Abstract

An ink-jet type forming device comprising a suction fan (11) for sucking from below a platen (12), a print medium (14) that is being conveyed on the platen (12), and a variable controller for variably controlling the suction force of the suction fan (11) under a predetermined condition. The variable controller that, in each scanning of a head, recognizes presence and absence of the head within a printing region ranging from the printing start position to the printing end position and that controls the suction fan such that the suction force is lower when the head is outside the printing region than when it is within the printing region, as the predetermined condition. Alternatively, it includes a detector that recognizes the kind of a print medium that has been set and that controls the suction force of the suction fan according to the recognized kind of print medium, as the predetermined condition. Adjustment of the suction force of the suction fan lowers the load on a conveyance motor and generally reduces power consumption and noise.
