摘要： When a printing head is filled with an ink, a circulating pump is controlled so that an ink equal to or greater than the entire volume of a circulating path circulates from a feeding path hole to a returning path hole via a printing head (in a forward direction), and after that, the circulating pump is controlled so that the ink equal to or greater than the entire volume of the circulating path circulates from the returning path hole to the feeding path hole via the printing head (in a reverse direction). By doing so, gas (bubbles) in the circulating path may be more securely discharged to a sub tank.

摘要： A printer has a carriage on which a recording head and pumps are mounted. An air supply device and ink cartridges are provided in a frame of the printer. The pumps are connected to the air supply device with an air supply tube. Each pump is connected to corresponding one of the ink cartridges with an ink supply tube. Based on actuation of a drive mechanism of the air supply device, air is supplied from the air supply device to the pumps. Based on changes in the pressure of the air, each pump draws ink from the corresponding ink cartridge and supplies the ink to the recording head. This permits the carriage to reciprocate in a reliable manner.

摘要： A liquid ejection apparatus includes a liquid ejection head that ejects a liquid and a switching device. The switching device includes a first ON-OFF valve that selectively opens and closes a first supply passage at a position upstream from the joining point, and a second ON-OFF valve that selectively opens and closes a second supply passage at a position upstream from the joining point. When the first ON-OFF valve is open and the second ON-OFF valve is closed, the liquid guide portion divides the first liquid into a first liquid flow proceeding from the first supply passage directly to the head supply passage and a second liquid flow flowing from the first supply passage into the head supply passage after passing the vicinity of the second ON-OFF valve in the second supply passage. When the first ON-OFF valve is closed and the second ON-OFF valve is open, the liquid guide portion divides the second liquid into a third liquid flow proceeding from the second supply passage directly to the head supply passage and a fourth liquid flow flowing from the second supply passage into the head supply passage after passing the vicinity of the first ON-OFF valve in the first supply passage.

摘要： A liquid ejecting apparatus includes an array of nozzles and a light-emitting portion that emits ultraviolet light. A control portion alternately and repetitively transports a medium in a transporting direction relative to the nozzles. The control portion forms a dot group in the transporting direction on the medium by ejecting a liquid toward the medium from the nozzles. The control portion also performs a light-emitting operation every time the control portion forms a dot group. The light-emitting operation is performed by causing the light-emitting portion to emit the ultraviolet light toward the dot group to cure the dot group. During the light-emitting operation, at least one of two ends of the dot group in the transporting direction is exposed to the ultraviolet light at a time later than the time at which a midsection of the dot group in the transporting direction is exposed to the ultraviolet light.
