A printer includes a carriage, a carriage moving mechanism including a motor, a motor driver that controls the motor, a stop instruction device, and an interlock device. The stop instruction device transmits a stop signal for the carriage or stops a driving permission signal for the carriage when a predetermined stop condition is satisfied. The interlock device is interposed between the motor and the motor driver and shuts off the motor from the motor driver after a lapse of a predetermined delay time of transmitting the stop signal or stopping the driving permission signal. The motor driver controls the motor to decelerate the carriage in at least a portion of a period before the delay time has elapsed.

A roll-fed printing apparatus for printing at least a first and a second image on a recording medium, a method for controlling such a printing apparatus and a software medium are disclosed. According to the method, each swath is printed by a print head that reciprocates in a scanning direction, the print head being controlled to apply marking material to the recording medium in accordance with a first set of image lines for each swath to be printed; the first set of image lines being provided to the print head from a swath buffer; wherein the first set of image lines are transmitted to the swath buffer out of a second set of image lines stored in a line buffer to be printed without interruption; wherein, when the line buffer comprises the final image lines of a first bitmap representing the first image while there are still empty data storage sections within the line buffer starting image lines of a second bitmap representing the second image are transferred to the empty data storage section of the line buffer.

A liquid discharging apparatus including a fixed section; a movable section that is mounted to be displaceable with respect to the fixed section; a rail section which has a planar portion, in which a plane is formed in a reference direction, and in which the planar portion is fixed to the movable section; and a carriage on which a head that is able to discharge a liquid is mounted and which is mounted on the rail section to be movable in the reference direction, in which the movable section is displaced with respect to the fixed section so as to rotate the rail section about an axis extending in the reference direction.

A recording apparatus includes an ink tank, a carriage, a recording head mounted on the carriage, a carriage control unit, and a supply tube connected to the recording head and the ink tank and including a bent portion that moves with carriage movement. The carriage control unit moves the carriage in predetermined directions to record on a recording medium. Assuming that, of an acceleration/deceleration area of a carriage moving area, an area in which pressure changes to decrease negative pressure in the recording head is a first area, and an area in which the pressure changes to increase the negative pressure in the recording head is a second area, the carriage control unit moves the carriage so that an absolute value of acceleration or deceleration of the carriage in the first area is less than an absolute value of acceleration or deceleration of the carriage in the second area.

A printing apparatus includes a discharging unit configured to discharge ink on a medium; a drive circuit configured to drive the discharging unit; a carriage configured to reciprocate in a scanning direction X while supporting the discharging unit and the drive circuit; and a blowing unit capable of blowing air toward the drive circuit supported on the carriage. The carriage includes a shielding member that partitions a discharging unit housing room from a drive circuit housing room. The discharging unit is disposed in the discharging unit housing room, and the drive circuit is disposed in the drive circuit housing room.

A liquid ejecting apparatus which ejects liquid onto a medium includes a carriage which includes a control substrate configuring at least a part of a control unit which controls driving of the entire liquid ejecting apparatus, an ejecting unit which ejects the liquid, and a driving substrate which is connected to the control substrate and the ejecting unit, and drives the ejecting unit, in which the carriage is provided with a fixing unit which fixes a position of the driving substrate with respect to a position of the ejecting unit. By adopting the liquid ejecting apparatus with such a configuration, it is possible to prevent a load from being applied to the ejecting unit from the driving substrate side.

A printing assembly includes: a print chassis having a fixed sleeve and a print module slidably and releasably mounted in a respective sleeve. The print module has a supply module and replaceable printhead cartidge, the printhead cartridge being slidably and releasably mounted to the supply module. The printhead cartridge is removable from the print module only when the print module is released from the fixed sleeve.

The present invention provides a mechanism that improves accuracy for positioning a head relative to a carriage, and easily performs positional adjustment for the head. A carriage unit includes a first carriage structure and a second carriage structure. The first carriage structure includes a first sliding face that can slide along a guide shaft, and a head can be mounted on the first carriage structure. The second carriage structure includes a second sliding face that can slide along the guide shaft, and can hold the first carriage structure to allow positional adjustment for the first carriage structure in a predetermined direction in which a position where the first sliding face contacts the guide shaft is to be shifted.

A printer includes: a media support defining a media feed path; and a pagewide printing unit for printing onto media fed along the media feed path. The printing unit includes: a maintenance chassis fixedly positioned over the media feed path, the maintenance chassis having a maintenance module fixedly mounted thereto; a print bar chassis movably mounted on the maintenance chassis, the print bar chassis including a print module having a printhead; and a lift mechanism for raising and lowering the print bar chassis relative to the maintenance chassis between a maintenance position a printing position. The printhead extends and retracts through a space defined by the maintenance module in the printing and maintenance positions, respectively.

A carriage includes: a base plate; a liquid jet head including a support plate attached to the base plate; a first engagement portion formed on one end in a Y direction of the support plate; a fixing tool for positioning and fixing the support plate with respect to the base plate, the fixing tool being fixed to the base plate slidably in an X direction by screws and engaged with the first engagement portion; and a flat spring portion that presses the fixing tool toward the base plate. The fixing tool allows movement in the Y direction of the first engagement portion with respect to the fixing tool, and restricts movement in the X direction of the first engagement portion and movement in a thickness direction of the base plate of the first engagement portion with respect to the fixing tool.
