摘要:
An image forming apparatus includes a recording head configured to have a nozzle face on which nozzles that discharge liquid droplets are formed; a cap configured to cap the nozzle face of the recording head; a discharge path configured to be connected to the cap; a suction pump configured to be provided in the discharge path and be made of a tube pump; and an atmosphere opening part configured to open an airtight space, created when the nozzle face is capped by the cap, to the atmosphere. The atmosphere opening part is configured to communicate with the inside of the cap at a position higher than a surface of liquid discharged into the cap, and a check valve configured to prevent a flow of the liquid toward the cap from the suction pump is provided in the discharge path.

An image forming apparatus includes a recording head, a cap, a suction unit, and a recovery device. The recording head has nozzles at a nozzle face to horizontally eject droplets of liquid. The cap caps the nozzle face of the recording head. The suction unit is connected to the cap. The recovery device drives the suction unit with the nozzle face capped with the cap to create a negative pressure in an internal space of the cap and suck the liquid from the recording head. The cap has a contact portion to contact the nozzle face and a suction port to communicate with the suction unit. The suction port is disposed away from the contact portion with a minute gap at a lowermost area of the cap in a vertical direction.

摘要:
An image forming apparatus includes an image forming unit forming an image on a recording medium; and a feeding unit feeding the recording medium in first and second directions opposite to each other relative to the image forming unit. Further when the recording medium is supplied from a first or second side of the feeding unit, while the feeding unit feeds the recording medium in the first or second feeding direction, the image forming unit forms an image on the recording medium, and the feeding unit further feeds the recording medium to the second or first side, respectively, of the feeding unit.
摘要:
An image forming apparatus includes an apparatus body, a recording head, a maintenance unit, a cover, and a controller. The recording head has a nozzle face and nozzles in the nozzle face to eject droplets of liquid. The maintenance unit has a cap to protect the nozzle face of the recording head. The cover opens an interior of the apparatus body to an outside of the apparatus body. The controller performs a normal control to cap the nozzle face of the recording head with the cap on opening of the cover and a special control to expose the nozzle face of the recording head to an area opened by the cover on receipt of an external instruction.
