Printer
A printer includes a first head including a first nozzle array including first nozzles arranged in a first direction and capable of ejecting a first liquid, a second head including a second nozzle array including second nozzles arranged in the first direction and capable of ejecting a second liquid on the first liquid, a first mover to relatively move the first head, the second head, and a medium in the first direction, and a second mover to move the first head and the second head in a second direction intersecting the first direction. An interval in the first direction between a range of use of the first nozzle array and a range of use of the second nozzle array is changed, while lengths of the range of use of the first nozzle array and the range of use of the second nozzle array in the first direction are respectively maintained.
1. A printer comprising:
a first head including a first nozzle array including a plurality of first nozzles arranged in a first direction and capable of ejecting a first liquid;
a second head including a second nozzle array including a plurality of second nozzles arranged in the first direction and capable of ejecting a second liquid that is to be ejected on the first liquid;
a first mover to relatively move the first head, the second head, and a medium in the first direction; and
a second mover to move the first head and the second head in a second direction intersecting the first direction; wherein
an interval in the first direction between a range of use of the first nozzle array and a range of use of the second nozzle array is changed, while lengths of the range of use of the first nozzle array and the range of use of the second nozzle array in the first direction are respectively maintained.
2. The printer according to claim 1 , wherein the first liquid is a processing liquid.
3. The printer according to claim 1 , further comprising a receiver to obtain information on at least one of temperature or humidity; wherein
the interval is changed based on the information.
4. The printer according to claim 3 , wherein the receiver includes a sensor to measure at least one of the temperature or the humidity.
5. The printer according to claim 3 , wherein the receiver is operable to obtain the information inputted by a user.
6. The printer according to claim 3 , wherein the receiver is operable to obtain a control signal to control a heater, to obtain the information.
7. The printer according to claim 3 , wherein the interval is reduced more as the temperature obtained by the receiver is higher or the humidity obtained by the receiver is lower.
8. The printer according to claim 3 , wherein the interval is increased more as the temperature obtained by the receiver is lower or the humidity obtained by the receiver is higher.
9. The printer according to claim 1 , wherein formation of dots to be formed in an area of the medium with a width corresponding to a single time of an amount of movement of a first moving operation by the first mover is completed by performing a plurality of times of a second moving operation by the second mover.
10. The printer according to claim 1 , wherein the interval is changed during printing.
11. The printer according to claim 10 , wherein when the interval is changed during printing, the length of the range of use of the first nozzle array in the first direction is temporarily changed, and then the length of the range of use of the first nozzle array in the first direction is returned to the length before the interval is changed.
12. The printer according to claim 1 , wherein the first nozzle array is located on an upstream side in the first direction with respect to the second nozzle array.
13. A printer comprising:
a first head including a first nozzle array including a plurality of first nozzles arranged in a first direction and being capable of ejecting a first liquid;
a second head including a second nozzle array including a plurality of second nozzles arranged in the first direction and capable of ejecting a second liquid that is to be ejected on the first liquid;
a first mover to relatively move the first head, the second head, and a medium in the first direction; and
a second mover to move the first head and the second head in a second direction intersecting the first direction; wherein
an interval in the first direction between a range of use of the first nozzle array and a range of use of the second nozzle array is changed, while an amount of movement when the first mover relatively moves the first head, the second head, and the medium in the first direction is maintained.
