摘要： A liquid-ejection-type image forming apparatus includes a recording head configured to print by ejecting ink liquid, and an electrostatic-absorption belt configured to convey printing paper. The liquid-ejection-type image forming apparatus performs a cockling-preventing mode operation which stops printing operation, separates the printing paper from the electrostatic-absorption belt, and restarts the printing operation after replacing the printing paper on the electrostatic-absorption belt.

摘要： An image forming apparatus includes a carriage carrying a recording head configured to discharge a droplet. A landing position error detecting pattern is formed on a pattern forming member. Based on a result of reading the landing position error detecting pattern, a landing position error of the droplet discharged by the recording head is corrected. Either a first pattern or a second pattern is selected as the landing position error detecting pattern, depending on a surface condition of the pattern forming member. The first pattern produces a relatively small amount of specular reflection compared with diffused reflection, while the second pattern produces a relatively large amount of specular reflection compared with diffused reflection, upon irradiation with light.

摘要： An image forming apparatus includes a recording head, a water-repellent transfer belt, a pattern formation controller, a read unit, and a detection unit. The recording head has a plurality of nozzles aligned in a given direction, and ejects droplets of a liquid therefrom. The pattern formation controller directs each of the plurality of nozzles to eject the liquid to form a detection pattern on the transfer belt. The detection pattern has multiple droplets ejected from each of the plurality of nozzles sequentially arranged and spaced apart from each other both in the given direction and in a direction orthogonal to the given direction. The read unit includes a light emitting element and a light receiving element, and reads the detection pattern to output a read result. The detection unit detects a defective nozzle according to the read result.

摘要： An image forming apparatus including a first carriage having a first recording head to eject black liquid droplets, a second carriage having a second recording head to eject color liquid droplets and separatably dockable with the first carriage, a position detector to detect a position of the second carriage relative to the first carriage in a state in which the first and second carriages are docked with each other, and a landing position corrector to correct landing positions of liquid droplets ejected from at least one of the first and second recording heads. The landing position corrector holds the position of the second carriage obtained by the position detector as a reference position and adjusts a correction amount for correcting the landing positions based on an amount of shift between the reference position and a present position of the second carriage docked with the first carriage.
