摘要

An ink jet device including a head having a nozzle surface formed with a nozzle through which ink droplets are ejected; a carriage on which the head is mounted; a cap for covering the nozzles of the head; a suction pump for generating pressure within the cap; a sheet feed mechanism for transporting a recording medium; a line feed motor for supplying a drive force; a switching mechanism for switching transmission of the drive force of the line feed motor from the sheet feed mechanism to the suction pump when the carriage enters a predetermined movement range and from the suction pump to the sheet feed mechanism when the carriage leaves the predetermined movement range; and cap movement mechanism moving the cap against the nozzle surface of the head while the carriage is at a position within the predetermined movement range and further moving the cap out of abutment with the nozzle surface of the head while the carriage is at another position within the predetermined movement range.
