Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink jet printer capable of removing ink adhered to an ink discharge port forming surface of a recording head for discharging ink to a recording medium.

[0002]

2. Description of the Related Art In an ink jet printer having a recording head having an ink discharge port forming surface on which a plurality of ink discharge ports for discharging ink to a recording surface of a recording medium is formed, after the recording operation is completed, the ink of the recording head is A recovery process is performed to always maintain normal ejection. The recovery process is, for example, to cause the recording head to perform preliminary ejection of ink. At that time, the ink adhering to the ink ejection port forming surface of the recording head causes the non-ejection of the ink and the ink landing position on the recording surface of the recording medium from the regular position when the recording operation is restarted. Therefore, it is necessary to remove the attached ink and maintain the ink discharge port forming surface in a clean state.

Therefore, in the ink jet printer, after the preliminary ejection of the ink is completed, the ink is discharged for a predetermined period of time, and the ink of each ink ejection port is ejected based on the head difference according to the negative pressure in the ink tank attached to the recording head. After being drawn into the flow path leading to the outlet, for example, a cleaning member made of a rubber material is slid in contact with the ink discharge port forming surface of the recording head and wiped off, so that the attached ink is removed.

[0004]

However, as described above, if the ink of each ink ejection port is left for a predetermined period until it is drawn into the flow path, the recovery process starts and ends. Time will be expended relatively much. Also, when ink is drawn into the flow path,
Dust and the like adhering to the ink discharge port forming surface may be drawn into the flow path together, which may cause a non-discharge of the ink.

In order to avoid such a situation, it is not necessary to leave the ink in each of the ink discharge ports for a predetermined period until the ink is drawn into the flow path. When the forming surface is wiped, when the one end of the bent cleaning member slidably contacting the ink discharge port forming surface is separated from the ink discharge port forming surface, the cleaning member returns to the original state, and thus adheres to the cleaning member. The scattered ink may scatter and contaminate the inside of the apparatus.

[0006] Further, in a case where the ink is not left for a predetermined period until the ink of each ink ejection port is drawn into the flow path, and the ink adhered by a porous material, for example, urethane foam, is removed, the urethane is used. Maintaining a predetermined distance between the surface facing the ink discharge port forming surface and the ink discharge port forming surface of the foam has a limit in the processing accuracy of the urethane foam, so the urethane foam can be formed without varying the distance. It is not easy to control the relative position between the end surface of the ink and the ink ejection port forming surface.

In view of the above problems, the present invention relates to an ink jet printer capable of removing ink adhering to an ink ejection port forming surface of a recording head for ejecting ink to a recording medium. And the dust and the like adhering to the ink ejection port forming surface are not drawn into the flow path together,
Moreover, an object of the present invention is to provide an ink jet printer that can easily control an appropriate relative position between an end surface of an ink removing member and an ink ejection port forming surface.

[0008]

In order to achieve the above object, an ink jet printer according to the present invention is provided with a recording head having an ink discharge port forming surface on which an ink discharge port for discharging ink is formed. An ink removing member having a plurality of plate-shaped portions which are disposed so as to be movable in a movable manner, and which adhere and remove the ink attached to the ink discharge port forming surface by capillary action, and provided in association with the ink removing member. An interval regulating member whose one end is in contact with the ink ejection port forming surface and regulates a predetermined distance between the ink ejection port forming surface and one end of the plate portion of the ink removing member; And a drive unit for moving the ink removing member and the interval regulating member relative to the recording head in order to remove the ink attached to the ink discharge port forming surface.
