Ink-jet printer, electronic apparatus including it and method for controlling them.

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. <IMAGE>
