Ink-jet printer

An ink-jet printer, comprising:

• a conveyor configured to convey a sheet in a conveyance direction;
• a carriage being movable in a main scanning direction along a sheet facing area, the main scanning direction intersecting the conveyance direction, and the sheet facing area facing the sheet conveyed by the conveyor;
• a recording head mounted on the carriage to discharge ink from a nozzle;
• a power supply configured to supply a drive voltage to the recording head;
• an ink receiver facing the recording head in a case that the carriage is positioned in a first position which is more to an outside in the main scanning direction than the sheet facing area;
• a command receiver;
• and
• a controller configured to control the conveyor, the carriage, the recording head, and the power supply to execute:
• determining a discharge ink amount that the recording head is to discharge toward the ink receiver;
• raising the drive voltage to a first voltage in a case that the determined discharge ink amount is less than a first threshold value, and raising the drive voltage to a second voltage higher than the first voltage in a case that the determined discharge ink amount is not less than the first threshold value;
• performing a flushing process in an area facing the ink receiver, the flushing process causing ink of the determined discharge ink amount to be discharged from the recording head toward the ink receiver, under a condition that the command receiver receives a recording command which is an instruction to record an image on the sheet and that the raising the drive voltage has finished;
• lowering the drive voltage from the second voltage to the first voltage, under a condition that the flushing process after raising the drive voltage to the second voltage has finished;
• and
• performing a printing process, under a condition that the flushing process has finished and that the drive voltage becomes the first voltage.
