Maintenance device, liquid ejecting device, and maintenance method for liquid ejecting device

A maintenance method for a liquid ejecting device including a liquid ejecting portion configured to eject liquid from a nozzle, a supply flow path configured to supply the liquid to the liquid ejecting portion, a cap configured to contact the liquid ejecting portion to form a closed space at which the nozzle is open, a cap moving portion configured to vertically move the cap, a suction portion, a switching portion configured to switch a coupling destination of the suction portion to the cap or the supply flow path, and a drive transmission unit for driving the cap moving portion and the switching portion,

• the drive transmission unit including
• a drive source,
• a first transmission mechanism that transmits drive force of the drive source from the drive source to the cap moving portion, and
• a second transmission mechanism that transmits the drive force of the drive source from the drive source to the switching portion,
• the first transmission mechanism including a first drive delay unit that does not transmit driving of the drive source even when the drive source drives by a certain amount when the drive source performs switching of the switching portion via the second transmission mechanism,
• the second transmission mechanism including a second drive delay unit that does not transmit driving of the drive source even when the drive source drives by a certain amount when the drive source performs moving of the cap moving portion via the first transmission mechanism, wherein
• the switching by the switching portion is performed in a section in which driving is not transmitted to the cap moving portion by the first drive delay unit,
• the first transmission mechanism includes a first friction clutch,
• the first friction clutch includes
• a first gear coupled to the first drive delay unit and
• a first intermittent gear that rotates by friction with the first gear, and
• the first intermittent gear is coupled to the cap moving portion,
• the maintenance method comprising:
• forming the closed space by the cap by moving the cap moving portion in a section in which the driving is not transmitted to the switching portion by the second drive delay unit;
• switching the coupling destination of the suction portion by the switching portion in a section in which the driving is not transmitted to the cap moving portion by the first drive delay unit;
• and
• suctioning by the suction portion.
