Abstract:
A liquid ejection apparatus including a liquid ejection head having a nozzle, a cleaning mechanism, and a controller. The controller includes a timer device, first memory section, second memory section, power supply, determining section, and tracked time correction section. If determination of the determining section is positive when the power supply is resumed, the tracked time correcting section reads out tracked time information from the second memory section and causes the timer device to start time tracking from the time indicated by the tracked time information that was stored when power supply to the liquid ejection apparatus was stopped. If the controller determines that the difference between the tracked time and the end time indicated by end time information stored in the first memory section is longer than or equal to a predetermined period, the controller operates the cleaning mechanism to carry out the cleaning.
