Abstract

PURPOSE:To prevent mixing of waste liquid of cleaning into ink by a method wherein the switchings of respective three-way solenoid valves for supplying and retrieving of an ink circulating system and a cleaning liquid circulating system are controlled by providing a timer circuit. CONSTITUTION:In the ink jet printer 1, there are provided the ink circulating system and the cleaning liqud circulating system, and the three-way solenoid valve 17 switching ink and cleaning liquid is provided at a nozzle 3 side while the three-way solenoid valve 18 fractionating and retrieving the ink and the cleaning liquid by switching is provided at the side arresting unnecessary ink particles by a gutter 10. The timer circuit for delaying the timing of the switching command of the three-way solenoid valve 18 for the retrieving side with respect to the switching command of the three-way solenoid valve 17 for the supplying side is provided. According to this constitution, since the solenoid valve 18 is switched after retrieving waste liquid of cleaing, which is remaining in a retrieving liquid circulating path, into a waste liquid tank 13 in case of switching from the cleaning process to an ink jet process, mixing of the waste liquid of cleaning into an ink tank 11 may be prevented.
