During sliding movement of the print bar carriage, the first bearings travel within the guide slot and bear against opposite guide surfaces to constrain rotational movement of the print bar carriage. | 05-21-2015 |
20150290940 | CAP DEVICE AND LIQUID JETTING APPARATUS PROVIDED WITH THE SAME - There is provided a cap device including a cap unit which is tillable in a plane direction of fee jetting surface and which comes into close contact with the jetting surface of the liquid jetting head; a flexible discharge tube of which one end is connected to the cap unit, which communicates with an inner space defined by the cap unit and the jetting surface wider a condition that the cap unh comes into close contact with the jetting surface, and through which a liquid in the inner space is discharged; and a fixing mechanism which fixes a portion, of the discharge tube, other than the one end to the cap unit. | 10-15-2015 |
20150306878 | IMAGE FORMING APPARATUS - An image forming apparatus includes a liquid ejection head, a cap, and a dummy discharge controller. The liquid ejection head has plural nozzle rows in a nozzle formed face thereof. Each of the plural nozzle rows includes multiple nozzles through which droplets are discharged. The cap caps the nozzle formed face of the liquid ejection head. The dummy discharge controller controls a dummy discharge operation to discharge dummy discharge droplets not contributing to image formation from the nozzles with the nozzle formed face opposed to the cap. The dummy discharge controller controls the liquid ejection head to discharge the dummy discharge droplets at different timings between adjacent nozzle rows of the plural nozzle rows in the dummy discharge operation. | 10-29-2015 |
20150343784 | MUZZLE FOR PRINTHEAD ASSEMBLY - A muzzle cap for a printhead assembly including a main body comprising a side wall, a top wall and a bottom wall, a vent seal disposed within an opening in the top wall, a nozzle plate seal disposed within an opening in the bottom wall, and a nozzle plate seal retainer that holds the nozzle plate seal within the opening in the bottom wall. | 12-03-2015 |
20150360487 | PRINTER - A printer includes a feeding portion for feeding a print medium in a first direction, an ejection portion for ejecting liquid, a carriage, a guide shaft, a rail member, a first pressing portion, an eccentric member, a regulating portion, and a prohibition portion. The carriage includes the ejection portion and reciprocates in a second direction which is orthogonal to the first direction. The guide shaft extends in the second direction and supports the carriage. The rail member is disposed facing the guide shaft. The first pressing portion presses a first surface of the rail member. The eccentric member has a rotating shaft portion and an eccentric shaft portion that is eccentric with respect to the rotating shaft portion. The regulating portion comes into contact with a second surface of the rail member, and regulates movement of the carriage. The prohibition portion prohibits rotation of the rotating shaft portion. | 12-17-2015 |
