摘要:
An ink-jet printer having an on-demand type ink-jet head (2) equipped with plural nozzles that eject ink droplets in response to pressure pulses generated by corresponding pressure generating elements and an electronic apparatus including the printer are disclosed to have timer means (34) that measures a prescribed time period, and recovery processing means (40) which performs recovery processing of said nozzles by causing ink ejection from the nozzles, wherein said recovery processing means (40) executes recovery processing at prescribed time intervals during non-operation of the ink-jet head based on said timer means 4. Also, said recovery processing means (40) performs initial recovery processing when the power supply is switched on. Further, an automatic power cut-off means operates when the number of consecutive recovery processes according to said timer means reaches a prescribed number.
摘要:
A print-medium transport unit including discharge rollers, a paper guide, and a lock member. The discharge rollers transport post-printed paper toward an outlet and can hold the leading end of the paper. The paper guide is placed upstream from the discharge rollers, and guides the leading end of the paper into the discharge rollers. The paper guide is rotatably supported so that the upstream side thereof opens a transport path of the paper, whereby when the leading end of the paper is held by the discharge rollers, the transport path allows the paper to be curved like a loop. The lock member locks the rotation of the paper guide when the leading end of the paper is guided into the paper guide. When the leading end of the paper reaches a predetermined position, the locking of the lock member is released.
