Abstract: The cleaning device includes a cleaning unit. The cleaning unit includes a cleaning part having a contact surface brought into contact with a surface of a conveyance roller to clean the surface of the conveyance roller, and a housing that supports the cleaning part. The cleaning part includes a web of a strip shape, the web forming the contact surface that comes in contact with the conveyance roller, a pressing roller that presses the web against the conveyance roller, a feed-out roller that feeds out the web so as to cause a part of the web that comes in contact with the conveyance roller to shift, and a take-up roller that takes up the web. The housing has an opening that receives foreign matter dropping from the vicinity of a nip portion formed between the pressing roller and the conveyance roller.

Abstract: A first storage portion stores, in advance, first reference voltage values respectively for ink ejection portions, the first reference voltage values corresponding to a predetermined first image density value. A second storage portion stores, in advance, voltage values that are different from each other, and measurement values that indicate image densities respectively corresponding to the voltage values. A voltage value calculating portion, at a predetermined change timing for changing image density, calculates second reference voltage values respectively for the ink ejection portions based on the voltage values and the measurement values, the second reference voltage values corresponding to a second image density value that is different from the first image density value. A voltage switching portion switches driving voltages that are applied to the ink ejection portions, from driving voltages having the first reference voltage values to driving voltages having the second reference voltage values.

Abstract: A recording head is provided with an ink ejection surface and a cleaning liquid supply surface. The ink ejection surface includes a nozzle region in which a plurality of ink ejection nozzles for ejecting ink onto a recording medium are open. The cleaning liquid supply surface is provided, with respect to the nozzle region, on an upstream side in a wiping direction in which a wiper wipes the ink ejection surface, and a plurality of cleaning liquid supply ports for supplying a cleaning liquid are open through the cleaning liquid supply surface. On the cleaning liquid supply surface, at least in a region including the cleaning liquid supply ports, a hydrophilic region having wettability with respect to water higher than that of the ink ejection surface is formed substantially evenly across an entire region in a width direction thereof orthogonal to the wiping direction.

Abstract: A recording head recovery mechanism has a wiper, a drive mechanism, and a controller. The controller can perform recording head recovery operation including a residual ink sticking step of letting residual ink at the tip of the wiper stick to a first position, and a wiping step of, after the residual ink sticking step, moving the wiper across an ink ejection surface from a second position, which is a position opposite from the nozzle region with respect to the first position, in a first direction toward the nozzle region to wipe off the residual ink along with purged ink.

Abstract: A conveyor device includes a support portion in which a through hole is formed and which is configured to support a to-be-conveyed medium; a negative pressure chamber configured to cause negative pressure to act on the to-be-conveyed medium through the through hole to suck the to-be-conveyed medium to the support portion; and a conveyance section configured to convey the to-be-conveyed medium sucked to the support portion. The negative pressure chamber includes a wall in which a communication hole to communicate the negative pressure chamber with the air is formed. The conveyor device further includes a shutter configured to slide on the wall of the negative pressure chamber to open/close the communication hole.
