Abstract

A liquid ejecting apparatus includes a first carriage movement mode, in which a stop position of a carriage in movement of this time is determined to be at a given position in a width direction on the basis of a size in the width direction of a liquid-ejected medium, and a second carriage movement mode, in which the stop position of the carriage in the movement of this time is determined on the basis of at least one of the liquid ejection data in the movement of this time or the liquid ejection data in the movement of the next time, and liquid ejection is carried out with one of the first carriage movement mode and the second carriage movement mode selected in accordance with the type of liquid-ejected medium.

First claim

What is claimed is:

1. A liquid ejecting apparatus comprising:
a liquid ejecting head which has nozzles and ejects liquid from the nozzles onto a liquid-ejected medium on the basis of liquid ejection data;
a carriage which carries the liquid ejecting head and moves in the width direction of the liquid-ejected medium; and
a control section which has a first carriage movement mode which determines a stop position of the carriage in this movement where the nozzles and a side end in the width direction of the liquid-ejected medium do not face each other, and a second carriage movement mode which determines a stop position of the carriage in this movement including the position where the nozzles and a side end in the width direction of the liquid-ejected medium face each other,
wherein the control section selects the first carriage movement mode in a case where a first type of medium is selected as the liquid-ejected medium, and the control section selects the second carriage movement mode in a case where a second type of medium is selected as the liquid-ejected medium,
wherein in the second carriage movement mode, the stop position of the carriage is determined without regard to a size in a width direction of the liquid-ejected medium.

2. The liquid ejecting apparatus according to claim 1 ,
wherein a main constituent of a material of the first type of medium is pulp, and
a main constituent of a material of the second type of medium is resin.

3. The liquid ejecting apparatus of claim 1 , wherein the control section transports the liquid-ejected medium when the carriage stops at the stop position.

4. The liquid ejecting apparatus of claim 1 , wherein selection of a carriage movement mode by the control section is made without regard to liquid ejection data corresponding to a next movement of the carriage.

5. The liquid ejecting apparatus of claim 1 , wherein in the first carriage movement mode, the stop position of the carriage in a width direction of the liquid-ejected medium is based on a size in a width direction of the liquid-ejected medium regardless of liquid ejection data corresponding to a next movement of the carriage.

6. The liquid ejecting apparatus of claim 1 , wherein in the second carriage movement mode, the stop position of the carriage is based on at least one of liquid ejection data corresponding to a most recent movement of the carriage and liquid ejection data corresponding to a next movement of the carriage.

7. A liquid ejecting apparatus comprising:
a liquid ejecting head which has nozzles and ejects liquid from the nozzles onto a liquid ejected medium on the basis of liquid ejection data;
a carriage which carries the liquid ejecting head and moves in the width direction of the liquid-ejected medium; and
a control section which has a first carriage movement mode which determines a stop position of the carriage in this movement where the nozzles and a side end in the width direction of the liquid-ejected medium do not face each other, and a second carriage movement mode which determines a stop position of the carriage in this movement including the position where the nozzles and a side end in the width direction of the liquid-ejected medium face each other, and selects one of the first carriage movement mode or the second carriage movement mode regardless of a size in a width direction of the liquid-ejected medium.

8. The liquid ejecting apparatus of claim 7 , wherein the control section transports the liquid-ejected medium when the carriage stops at the stop position.

9. A liquid ejecting apparatus comprising:
a liquid ejecting head which has nozzles and ejects liquid from the nozzles onto a liquid-ejected medium on the basis of liquid ejection data;
a carriage which carries the liquid ejecting head and moves in the width direction of the liquid-ejected medium; and
a control section which has a first carriage movement mode which determines a stop position of the carriage in this movement where the nozzles and a side end in the width direction of the liquid-ejected medium do not face each other, and a second carriage movement mode which determines a stop position of the carriage in this movement including the position where the nozzles and a side end in the width direction of the liquid-ejected medium face each other,
wherein the control section selects the first carriage movement mode in a case where a first type of medium is selected as the liquid-ejected medium, and the control section selects the second carriage movement mode in a case where a second type of medium is selected as the liquid-ejected medium,
wherein selection of a carriage movement mode by the control section is made without regard to liquid ejection data corresponding to a next movement of the carriage.
