INK JET TYPE IMAGE FORMING DEVICE
Document Type and Number:
WIPO Patent Application WO/2000/034049
Kind Code:
A1
Abstract:
An ink jet type image 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 control means for variably controlling the suction force of the suction fan (11) according to predetermined conditions. The variable control means has a means that, as a predetermined condition and in each scanning of a head, recognizes presence or absence of the head in a printing region ranging from the printing start position to the printing end position and that controls 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. Alternatively, it has a means that, as a predetermined condition, 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. Adjustment of the suction force of the suction fan lowers the load on a conveyance motor and generally reduces power consumption and noise.
