Abstract

A liquid discharge apparatus includes a liquid discharge head, a second medium, and a cleaner. The liquid discharge head discharges a liquid on the first medium. The second medium is different from the first medium. The liquid discharge head is dischargeable the liquid onto the second medium to form a test pattern. The cleaner cleans the second medium to remove the test pattern from the second medium.

First claim

The invention claimed is:

1 . A liquid discharge apparatus comprising:
a liquid discharge head configured to discharge a liquid on a first medium; a second medium different from the first medium, the second medium onto which the liquid discharge head is dischargeable the liquid to form a test pattern; a cleaner configured to clean the second medium to remove the test pattern from the second medium; and a mover configured to move the second medium between
a discharge position at which the liquid discharge head discharges the liquid onto the second medium; and
a cleaning position at which the cleaner cleans the second medium,
wherein the cleaner includes a cleaning nozzle configured to spray a cleaning liquid to the second medium to clean the second medium, the cleaning nozzle laterally fixed in a position above the second medium, and wherein the mover includes a linear motion power cylinder configured to linearly move the second medium between the discharge position and the cleaning position.

2 . The liquid discharge apparatus according to claim 1 , further comprising a dryer configured to dry the second medium cleaned by the cleaner.

3 . The liquid discharge apparatus according to claim 2 ,
wherein the dryer includes an air nozzle configured to blow air onto a surface of the second medium.

4 . The liquid discharge apparatus according to claim 2 ,
wherein the dryer includes an absorber configured to contact the second medium and absorb the cleaning liquid on the second medium.

5 . The liquid discharge apparatus according to claim 1 ,
wherein the cleaner includes an impregnated component impregnated with the cleaning liquid, and the cleaner causes the impregnated component to contact a surface of the second medium.

6 . The liquid discharge apparatus according to claim 5 , further comprising the mover configured to move the second medium,
wherein the impregnated component is stationary, and the mover is configured to move the second medium to cause the second medium to contact the impregnated component.

7 . The liquid discharge apparatus according to claim 1 ,
wherein the cleaner includes:
the cleaning nozzle being a fluid nozzle;
a supply path configured to supply the cleaning liquid to the fluid nozzle;
an air supply path configured to supply air to the fluid nozzle; and
a switch configured to switch to connect the fluid nozzle with one of the supply path and the air supply path.

8 . The liquid discharge apparatus according to claim 1 , further comprising a drain path configured to drain the cleaning liquid from the second medium.

9 . The liquid discharge apparatus according to claim 1 , further comprising a head cleaner configured to maintain and recover the liquid discharge head.

10 . The liquid discharge apparatus according to claim 9 ,
wherein the cleaner configured to clean the second medium includes:
an air nozzle configured to blow air onto a surface of the second medium;
a supply path configured to supply the cleaning liquid to the cleaning nozzle;
a drain path configured to drain the cleaning liquid from the second medium; and
an air supply path configured to supply the air to the air nozzle, and
the cleaner configured to clean the second medium and the head cleaner share at least one of the cleaning nozzle, the air nozzle, the supply path, the drain path, or the air supply path to clean both of the liquid discharge head and the second medium.

11 . The liquid discharge apparatus according to claim 1 , further comprising:
a detector configured to detect the test pattern formed on the second medium; and circuitry configured to drive the liquid discharge head to discharge the liquid onto the first medium in accordance with the test pattern on the second medium detected by the detector.

12 . The liquid discharge apparatus according to claim 11 ,
wherein the detector includes a camera sensor configured to capture an image indicating a moving state, a cleaning state, or a drying state of the second medium.

13 . The liquid discharge apparatus according to claim 1 , further comprising a detector configured to detect the test pattern formed on the second medium,
wherein the mover further is configured to move the second medium to a detection position at which the detector detects the test pattern on the second medium, and the detection position is between the discharge position and the cleaning position.

14 . A liquid discharge apparatus comprising:
a liquid discharge head configured to discharge a liquid on a first medium; a second medium different from the first medium, the second medium onto which the liquid discharge head is dischargeable the liquid to form a test pattern; a cleaner configured to clean the second medium to remove the test pattern from the second medium; and a mover configured to move the second medium between
a discharge position at which the liquid discharge head discharges the liquid onto the second medium; and
a cleaning position at which the cleaner cleans the second medium,
wherein the cleaner includes a cleaning nozzle configured to spray a cleaning liquid to the second medium to clean the second medium, the cleaning nozzle laterally fixed in a position above the second medium, and wherein the mover includes a robot arm.

15 . A liquid discharge apparatus comprising:
a liquid discharge head configured to discharge a liquid on a first medium; a second medium different from the first medium, the second medium onto which the liquid discharge head is dischargeable the liquid to form a test pattern, the liquid discharge head including a detector configured to detect a moving state of the second medium; a cleaner configured to clean the second medium to remove the test pattern from the second medium; a mover configured to move the second medium between:
a discharge position at which the liquid discharge head discharges the liquid onto the second medium, and
a cleaning position at which the cleaner cleans the second medium; and
a controller configured to control the liquid discharge head, the cleaner, and the mover based on a detection result of the detector.
