Summary:A maintenance device for a fluid ejection head has a small, compact switching mechanism that can appropriately switch drive force from a drive source and drive a suction pump and a wiper. A maintenance device 40 has caps 64 (1) to 65 (4) and wipers 75 (1) to 75 (4), a suction pump 94 that suctions waste ink from the caps 64 (1) to 65 (4), a cap drive transfer mechanism 80 that moves the caps 64 (1) to 65 (4) in a cap movement direction V, a wiper-pump drive transfer mechanism 90 that moves the wipers and drives the suction pump 94, and a drive switching mechanism 100 that switches driving by the wiper-pump drive transfer mechanism 90 to drive the suction pump 94 or move the wipers according to the position of cap movement.
