Recording device and method for controlling the recording device

Abstract

To solve such a problem that there is a risk that a user may have to confirm an image recorded on a medium by a recording head to perform maintenance of the recording head and correction of a conveyance amount.SOLUTION: A recording device 11 comprises: an upstream-side conveying roller pair 35 that can convey a medium M1; a recording head 22 that records an image P on the medium M1 conveyed by a predetermined conveyance amount FA toward a downstream side in a D1 direction by the upstream-side conveying roller pair 35, by discharging ink at a predetermined timing, while moving in a Y-axis direction crossing the D1 direction; a photographing part 90 that can read out the image P recorded on the medium M1 by the recording head 22; and a control part 58. The control part 58 performs any of maintenance of discharge defect of ink, correction of the conveyance amount FA and correction of a timing of discharging ink, on the basis of a read-out result of the image P read out by the photographing part 90.SELECTED DRAWING: Figure 3

Claims

1. A transport unit capable of transporting media, A recording head that records an image by discharging liquid at a predetermined timing while moving in a scanning direction intersecting the transport direction onto the medium that has been transported by the transport unit by a predetermined amount downstream in the transport direction, A reading unit capable of reading the image recorded on the medium by the recording head, A detection unit is provided between the transport unit and the recording head to detect the leading edge of the medium in the transport direction, Control unit and Equipped with, The reading unit is provided within the recording unit, which includes the transport unit and the recording head. The reading unit is provided upstream of the transport unit in the transport direction, The control unit controls the transport unit and the recording head to record a confirmation pattern on the medium being transported downstream in the transport direction, which includes a pattern for confirming the liquid discharge state, a pattern for confirming the transport amount, and a pattern for confirming the liquid discharge timing. When the control unit causes the confirmation pattern to be recorded on the medium, it causes the confirmation pattern to be recorded on the upstream end of the medium in the transport direction, The control unit controls the transport unit and the reading unit to transport the medium on which the verification pattern is recorded upstream in the transport direction, and then causes the reading unit to read the verification pattern. The control unit performs maintenance for the liquid discharge failure, corrects the transport volume, and corrects the discharge timing based on the reading result of the verification pattern read by the reading unit. A recording device characterized by the following features.

2. The verification pattern is recorded on the medium by the recording head discharging the liquid while moving back and forth once in the scanning direction. The recording device according to feature 1.

3. The reading unit is an image sensor capable of capturing images of the medium across the width direction of the medium, which is a direction intersecting the transport direction. The recording device according to claim 2.

4. The pattern for confirming the discharge timing is recorded in the center of the medium in the scanning direction. The recording device according to feature 2 or 3.

5. If the control unit determines from the reading results obtained by the reading unit that maintenance is required for the discharge malfunction, it will not perform the correction even if it determines that either the correction of the transport amount or the correction of the discharge timing is required. A recording device according to any one of claims 1 to 4.

6. Based on the reading results obtained by the reading unit, the control unit confirms with the user whether or not to perform any of the following actions before executing: maintenance for the discharge defect, correction of the transport amount, or correction of the discharge timing. A recording device according to any one of claims 1 to 5, characterized by the features described above.

7. A discharge and transport unit is provided on the downstream side of the recording head in the transport direction for discharging the medium from within the recording unit. Before ejecting the medium from the recording unit, the control unit causes the reading unit to read the image recorded on the medium. A recording device according to any one of claims 1 to 6.

8. A control method for a recording device comprising: a transport unit capable of transporting a medium; a recording head that records an image on the medium by discharging liquid onto the medium being transported downstream in the transport direction by the transport unit; a housing that houses the transport unit and the recording head; a reading unit provided upstream of the transport unit in the transport direction and capable of reading the image recorded on the medium by the recording head; a detection unit provided between the transport unit and the recording head and detecting the leading edge of the medium in the transport direction; and a discharge transport unit located downstream of the recording head in the transport direction for discharging the medium from the housing, wherein By controlling the transport unit and the recording head, a confirmation pattern is recorded on the upstream end of the medium being transported downstream in the transport direction, relative to the center in the transport direction. This pattern includes a pattern for confirming the liquid discharge state, a pattern for confirming the transport amount, and a pattern for confirming the liquid discharge timing. By controlling the transport unit and the reading unit, the medium on which the verification pattern is recorded is transported upstream in the transport direction, and then the reading unit is made to read the verification pattern. Based on the reading result of the verification pattern read by the reading unit, maintenance for the liquid discharge failure, correction of the transport amount, and correction of the discharge timing are performed. A method for controlling a recording device.
