Flushing method for fluid ejecting apparatus

摘要

A flushing method is performed in a fluid ejecting apparatus (10). The flushing method includes: repeatedly performing first flushing with a first period; and repeatedly performing second flushing with a second period. The first and second flushing include: generating a negative pressure in a pressure chamber (13) in such a manner that the pressure generating element (16) is driven to cause the pressure chamber to expand into an expanded state (fig 5A); keeping the expanded state (fig 5B); and discharging the fluid from a nozzle (15) by causing the pressure chamber to contract from the expanded state (fig 5C). The amount of the second flushing is larger than that of the first flushing.
