Abstract: The invention enables even further improvement in quality of a recording image. A recording method for recording on a recording paper comprises the steps of: carrying the recording paper for a predetermined amount, based on a first carrying amount for which the recording paper is to be carried; executing recording on the recording paper that has been carried for the predetermined amount; executing an addition process of adding an amount obtained by subtracting the predetermined amount from the first carrying amount to a second carrying amount for which the recording paper is to be carried; and carrying the recording paper based on the second carrying amount to which the addition process has been executed.

Abstract: The present invention is a liquid ejecting apparatus including: a head member having a nozzle and a liquid-ejecting unit that ejects liquid in the nozzle; a main controlling part that drives the liquid-ejecting unit based on ejecting data; and a capping member relatively movable between a position away from the head member and a position in contact with the head member. A suction way is communicated with an inside of the capping member, and a built-in slide-rotator type of positive displacement pump is provided in the suction way. A release mechanism can release the inside of the capping member to an atmosphere even when the capping member is in contact with the head member.

Abstract: When ink is sucked from the nozzles during a cleaning process, a rubber cap having a plural number of small spaces independently operable for ink suction is applied to a print head, and only the small space associated with a clogged nozzle of those nozzles of the print head is connected to a suction pump. A user looks up in advance the number and location of a clogged nozzle, judges the cause of the clogging of the nozzle on the basis of the number and location of the clogged nozzle, and selects a suitable type of cleaning process, a selective cleaning (based on the specified-nozzle suction) or a conventional cleaning (based on the all-nozzle suction). A valve unit is arranged in an ink supply path located between an ink cartridge and a recording head. The valve unit controls the opening and closing of the ink supply paths between the ink cartridge and the nozzle openings during the cleaning operation of the recording head. For example, air bubbles entered into the recording head when the ink cartridge is replaced, can be discharged by opening the valve unit. By closing valve units disposed on the other recording head that does not receive a new ink cartridge, unnecessary ink suction discharging ink equally through all nozzle openings can be avoided. Therefore, an ink jet recording apparatus capable of reducing the running costs is provided.

A state-quantity recognizing part recognizes a state quantity related to a dry state in an inside of the positive displacement pump. A judging part judges whether the inside of the positive displacement pump is dry, by comparing the state quantity with a standard state quantity. A preliminary-operation carrying-out part carries out a preliminary operation for wetting the inside of the positive displacement pump, when the inside of the positive displacement pump is dry.

Abstract: A sucking device having a fixed material transportation surface including plural sucking holes, a decompression chamber connecting to the plural sucking holes, and a sucking device sucking air in the decompression chamber is set at discharging side of the fixed material. The fixed material is fed on the fixed material transportation surface of the sucking device by the delivering device, and is stuck on the fixed material transportation surface through the sucking holes by the sucking device. The fixed material is fixed by a fixing head at the state being stuck and is transported gradually to a downstream side from an upstream side by the delivering device on the fixed material transportation surface. After that, when fixing is finished, the fixed material separates from surface of the fixed material transportation surface and rises slightly by blowing air from the sucking holes by a blowing device so as to move to discharging direction, that is, the downstream side by an auxiliary transporting device. Thus, since the fixed material is discharge smoothly, the prior discharging serrated roller is unnecessary so that spur mark run over caused by the discharging serrated roller does not remain on the fixed material at discharging.
