Recording device and method of controlling recording device

A recording device comprising:

• a recording section that discharges a liquid to a medium for recording purposes;
• a maintenance unit that abuts the recording section and performs maintenance of the recording section;
• a moving section that causes one of the recording section and the maintenance unit to abut another of the recording section and the maintenance unit and separates the one of the recording section and the maintenance unit from the another of the recording section and the maintenance unit;
• a restricting section provided on at least one of the recording section and the maintenance unit and configured to suppress movement of the one of the recording section and the maintenance unit toward the another of the recording section and the maintenance unit by contacting with the one or the another of the recording section and the maintenance unit after the recording section and the maintenance unit mutually abut;
• and
• a controller that controls the moving section, wherein
• the moving section has
• a driving source, and
• a worm gear that transmits power of the driving source,
• the driving source drives in a first direction with a first driving force so that the one of the recording section and the maintenance unit abuts the another of the recording section and the maintenance unit, and drives in a second direction opposite to the first direction with a second driving force and with which so that the one of the recording section and the maintenance unit separates from the another of the recording section and the maintenance unit,
• the controller sets the first force with which the driving source causes the one of the recording section and the maintenance unit to abut the another of the recording section and the maintenance unit so as to be smaller than the second force with which the driving source separates the one of the recording section and the maintenance unit from the another of the recording section and the maintenance unit,
• the controller moves the one of the recording section and the maintenance unit in a direction toward the another of the recording section and the maintenance unit until a load of the driving source reaches a predetermined value,
• the controller sets
• a first position of the one of the recording section and the maintenance unit at a time when the load of the driving source reaches the predetermined value, as a contact position, and
• a second position the one of the recording section and the maintenance unit away from the contact position and toward the another of the recording section and the maintenance unit by a first predetermined distance, as a target position, and
• when the one of the recording section and the maintenance unit is not able to move to a confirmation position, which is away from the target position by a second predetermined distance and toward the another of the recording section and the maintenance unit, with the first driving force but is able to move to the confirmation position by use of a third driving force of the driving source, which is greater than the first driving force, the controller sets, as the third driving force, the force with which the one of the recording section and the maintenance unit abuts the another of the recording section and the maintenance unit.
