Image forming apparatus including recovery device to recover droplet discharge head
An image forming apparatus includes a recovery device to recover a droplet discharge head. The recovery device includes a slider and a suction unit. The slider contacts a nozzle formation face of the droplet discharge head and moves along a nozzle row of the droplet discharge head. The slider includes two portions spaced away from each other in a direction traversing a movement direction of the slider. The suction unit opposes nozzles of the droplet discharge head and moves without contacting the nozzle formation face. The suction unit is disposed at a position between the two portions of the slider and downstream from the two portions of the slider in the movement direction of the slider. The slider collects droplets adhered to an area outside the nozzle row of the nozzle formation face.
1. An image forming apparatus comprising:
a droplet discharge head including a nozzle formation face and one or more rows of nozzles on said nozzle formation face; and
a recovery device for recovering the droplet discharge head, the recovery device including a droplet absorber to oppose the nozzle formation face of the droplet discharge head; and
a suction unit to contain the droplet absorber and move along a nozzle row of the droplet discharge head to suction liquid from the nozzle formation face,
the droplet absorber including an opposing face to oppose the nozzle formation face, the opposing face including
a first portion to oppose the nozzles of the nozzle formation face, and a second portion to oppose an area of the nozzle formation face outside the nozzles, the second portion being disposed to have a space between the second portion and
the nozzle formation face during a suction operation of the suction unit, and
the first portion being disposed relatively farther from the nozzle formation face than the second portion, and
inner corners formed between the first portion and the second portion and disposed close to but not in contact with the nozzle row to contact droplets on the nozzle row during a suction operation of the suction unit.
2. The image forming apparatus according to claim 1 , wherein the droplet absorber opposes an area in vicinity of the nozzle row and moves droplets on the nozzle row to the second portion to remove the droplets.
3. The image forming apparatus according to claim 1 , wherein the droplet absorber is positioned to cover two areas in vicinity of the nozzle row in a direction traversing a movement direction of the droplet absorber, and moves droplets on the nozzle row in the two areas to the second portion to remove the droplets.
4. The image forming apparatus according to claim 1 , further comprising a cover disposed on the first portion.
5. The image forming apparatus according to claim 1 , further comprising an extension attached to the nozzle formation face to maintain a negative pressure acting on the droplet absorber.
6. A device for recovering a droplet discharge head, the recovery device comprising:
a droplet absorber to oppose a nozzle formation face of the droplet discharge head; and
a suction unit to contain the droplet absorber and move along a nozzle row of the droplet discharge head to suction liquid from the nozzle formation face,
the droplet absorber including an opposing face to oppose the nozzle formation face, the opposing face including
a first portion to oppose nozzles of the nozzle formation face, and a second portion to oppose an area of the nozzle formation face outside the nozzles, the second portion being disposed to have a space between the second portion and
the nozzle formation face during a suction operation of the suction unit, and
the first portion being disposed relatively farther from the nozzle formation face than the second portion, and
inner corners formed between the first portion and the second portion and disposed close to but not in contact with the nozzle row to contact droplets on the nozzle row during a suction operation of the suction unit.
