A printing apparatus includes: a printer that performs printing on a printing medium; and a sensor that outputs a detection signal while the printing apparatus moves relative to the printing medium. The printing apparatus determines whether the sensor is above a first surface or above a second surface of the printing medium, based on the detection signal output from the sensor, the first surface being a surface on which a moving amount of the printing apparatus with respect to the printing medium is acquired, and the second surface being a surface on which the moving amount is not acquired, and if the sensor is determined to be above the second surface, controls printing on the printing medium by the printer according to an estimated value of the moving amount with respect to the printing medium.

A print bar for a for a multi-pass printer, the print bar comprising a static part configured to extend across a print area of a print target and a moveable part comprising a print bar beam and printer comprising such a print bar.

In an image forming apparatus, a carriage mounts a recording head for discharging droplets, and moves in a main scan direction. A guide member slidably guides the carriage. An encoder scale is arranged along the main scan direction. An encoder sensor reads the encoder scale. The carriage includes a head mounting part for mounting the recording head, and a sensor attaching part for attaching the encoder sensor. The sensor attaching part is provided so as to be extended from the head mounting part. The encoder scale is arranged at a location which the encoder sensor can read. A partition member is provided to separate the head mounting part from the sensor attaching part in the carriage. The head mounting part is arranged in a first space, and the sensor attaching part and the encoder scale are arranged in a second space separated from the first space by the partition member.

A printing apparatus includes a carriage mounted with a printing unit configured to perform printing on a print medium, a first motor used to move the carriage, a second motor used together with the first motor to move the carriage, and a control unit configured to control the first motor and the second motor. When moving the carriage, the control unit controls the first motor with a first control amount and controls the second motor with a second control amount. The first control amount and the second control amount are different from each other, and a ratio therebetween is a predetermined ratio.

An inkjet printer has a printing head, a sheet conveying mechanism, a carriage mounting a printing head and configured to be reciprocally movable in a printing area and non-printing area. A cap is provided to be movable between a capping position an uncap position. A controller of the inkjet printer is configured to execute a printing process, a standby process, and a capping process in which the controller causes the carriage to move to the non-printing area and moves the cap from the uncap position to the capping position. The controller causes the carriage to move into the printing area when the next printing command is received after the standby process is finished and before the carriage moving process has been completed.

In an image forming apparatus, a carriage mounts a recording head for discharging droplets, and moves in a main scan direction. A guide member slidably guides the carriage. An encoder scale is arranged along the main scan direction. An encoder sensor reads the encoder scale. The carriage includes a head mounting part for mounting the recording head, and a sensor attaching part for attaching the encoder sensor. The sensor attaching part is provided so as to be extended from the head mounting part. The encoder scale is arranged at a location which the encoder sensor can read. A partition member is provided to separate the head mounting part from the sensor attaching part in the carriage. The head mounting part is arranged in a first space, and the sensor attaching part and the encoder scale are arranged in a second space separated from the first apace by the partition member.

A recording apparatus includes a carriage which includes a recording head that performs recording on a medium and is movable in a predetermined direction; and a power supply unit that supplies power for driving drive targets including the carriage, wherein the power supply unit is located at a position in a movement area of the carriage. The power supply unit is disposed on an apparatus front side with respect to the movement area of the carriage in an apparatus depth direction, which is a direction intersecting the movement direction of the carriage. The power supply unit is disposed on an upper side of a medium transportation path in the vertical direction.

The disclosure discloses a printer includes a controller. The controller performs a first feed control process, a temperature-difference calculation process, and a first printing speed determination process. In the first feed control process, in a state where an energizing device does not perform energization to the heating element, the driving device is controlled to perform non-energization feeding while causing a thermal head to contact a print-receiving medium. In the temperature-difference calculation process, during execution of the non-energization feeding, a first deviation between two of the head temperatures which are respectively detected by the first temperature detecting device at different timings is calculated. In the first printing speed determination process, the printing speed is determined on the basis of the first deviation.

A printer includes: a processor; a print head configured to perform printing in accordance with input print data; and a scanner configured to acquire an image of a material to be printed. The processor is configured to detect at least one line extending in a first direction on the material to be printed from the image acquired by the scanner when moving of the printer in a moving direction in which the scanner is on the front side of the print head, and set a print area along the first direction based on the line on the material to be printed, and the print head prints in the print area.

A device includes a head to perform an operation on a conveyed object; a head moving device to move the head in a width direction orthogonal to a conveyance direction of the conveyed object; a position detector to detect a position of the conveyed object in the width direction; a speed detector to detect a moving speed of the conveyed object in the width direction; a position predictor to obtain a predicted width position of the conveyed object after a predetermined period, based on a detected position of the conveyed object and a detected moving speed of the conveyed object; a speed calculator to calculate a travel speed of the head; and a head travel controller to control the head moving device to move the head at the calculated travel speed. With the calculated travel speed, the head arrives at the predicted width position after the predetermined period.
