  • Publication number: 20220009244
    Abstract: A print head includes a nozzle array comprising a plurality of nozzles, and a negative pressure generating portion configured to apply a negative pressure to the nozzle array. A tank includes a storage portion and an air communication port. A tube connects the print head and the tank and supply the liquid from the tank to the print head. A highest position of a liquid level in the tank in the vertical direction is higher than a position of the nozzle array, and an absolute value of a water head difference caused by a difference between the highest position of the liquid level in the tank and the position of the nozzle array is not larger than an absolute value of a negative pressure generated by the negative pressure generating portion.

  • Publication number: 20200039241
    Abstract: Provided is a technique that makes it possible to obtain positional information for determining a print position depending on the type of print medium. A determining unit determines a process for obtaining information on the position of the print medium by using a detecting unit, depending on the type of the print medium. An obtaining unit obtains the information on the position of the print medium by changing the relative position of the detecting unit with respect to the holding unit holding the print medium, based on the process determined by the determining unit. Then, a setting unit determines a print position for the print medium based on the information on the position of the print medium.
