Abstract
An ink-jet printer including a conveyor, a carriage, a recording head, a power supply, an ink receiver, a command receiver, and a controller, is provided. The controller executes the steps of: determining a discharge ink amount that should be discharged to the ink receiver; raising a drive voltage to a first voltage when the discharge ink amount is less than a first threshold value, and raising the drive voltage to a second voltage when the discharge ink amount is the first threshold value or more; performing a flushing process; based on the flushing process after having raised the drive voltage to the second voltage having finished in the case of having raised the drive voltage to the second voltage, stepping down the drive voltage from the second voltage to the first voltage; and based on the flushing process having finished and on the drive voltage being the first voltage, performing a printing process.
