Abstract:
An inkjet printer includes: a pressurized space and a depressurized space for circulation of ink along a circulation path; a main connection path and an adjustment path connecting the pressurized space and the depressurized space to each other; an air pump configured to send air from the depressurized space to the pressurized space though the main connection path or the adjustment path; a changeover device configured to change over between the main connection path and the adjustment path; and a controller. The controller drives the air pump with the main connection path being set to generate preset pressures respectively in the pressurized space and the depressurized space and then controls the air pump with the adjustment path being changed over to maintain pressures in the pressurized space and the depressurized space respectively at the preset pressures.

Claim (Index 1):
An inkjet printer comprising:\n a print unit configured to eject ink from a nozzle of an inkjet head while circulating the ink along a circulation path; a pressurized space configured to be pressurized for circulation of the ink along the circulation path; a depressurized space configured to be depressurized for the circulation of the ink along the circulation path; a main connection path connecting the pressurized space and the depressurized space to each other; an adjustment path connecting the pressurized space and the depressurized space to each other, the adjustment path formed by a portion of the main connection path and a path having an air passage narrower than an air passage of the main connection path; an air pump arranged in the portion of the main connection path and configured to send air from the depressurized space to the pressurized space; a changeover device configured to change over a usage path from the main connection path to the adjustment path and vice versa, the usage path being a path used as an air passage between the pressurized space and the depressurized space in drive of the air pump; and a controller configured to drive the air pump with the main connection path set as the usage path by the changeover device to generate preset pressures respectively in the pressurized space and the depressurized space and then control the drive of the air pump with the usage path changed over to the adjustment path by the changeover device to maintain pressures in the pressurized space and the depressurized space respectively at the preset pressures.
