Abstract (en)
A method of adjusting an ink suction amount in an ink jet printer includes the steps of: determining an ink suction amount according to a printing state; and sucking the ink from a head according to the determination. Therefore, since the ink is sucked by moving the piston as much as a predetermined distance according to the clogging state of the nozzle, unnecessary consumption of the ink can be prevented. Simultaneously, since the piston only moves to the predetermined position, a suction time can also be curtailed. Thus, the ink cartridge life can be extended, and work efficiency can be improved as a recovery time to a normal state from the clogged state is reduced. <IMAGE>
