A printing device printing on a medium while being manually moved in relation to the medium is provided. The printing device includes: a speed detection unit detecting a speed of movement at which the printing device is moved; and a stop control unit stopping the printing when the speed of movement exceeds a threshold.

An ink-jet printing apparatus includes: a conveying part that conveys a print medium; a plurality of discharge heads that is arranged along a direction of conveying the print medium, and discharges ink onto the print medium to perform printing an the print medium; a moving part that moves the discharge heads such that distances between the print medium and the discharge heads are changed from a set distance; and a hardware processor that controls printing on the print medium, wherein the hardware processor corrects a print distance such that the print distance is changed from a predetermined value in response to the discharge heads being moved in such a way as to change the distances between the print medium and the discharge heads, the print distance being a conveying distance of the print medium to be conveyed while printing on the print medium is performed by the discharge heads.

An adjusting mechanism includes an adjusting plate and a screw type adjuster. The adjusting plate is provided in at least one end of an interlocking shaft that interlocks a pair of driving belts provided in a second direction and is attached to an end of the interlocking shaft. The screw type adjuster is configured to be capable of adjusting a position of a moving body engaged to the pair of driving belts by being rotated to move the adjusting plate along a first direction different from the second direction.

A liquid discharging apparatus, having a head with nozzles, a scanning assembly, a conveyer, and a controller, is provided. The controller is configured to determine whether the nozzles are to be flushed in a moving action which accompanies a discharging action, if the controller determines the nozzles are not to be flushed in the moving action, conduct the moving action to move the head at a first acceleration rate; if the controller determines the nozzles are to be flushed in the moving action, determine whether a distance between a flushing range and a discharging range is greater than or equal to a predetermined distance; and if the controller determines the distance is greater than or equal to the predetermined distance, conduct the moving action to move the head at a second acceleration rate and control the head to discharge liquid for flushing the nozzles.

There is disclosed a device, method and program, wherein the method comprises detecting a power increase, during which power usage increases by at least a threshold amount over an expected power usage during movement of a printer carriage over a print medium along a scan axis. The increase method further comprises detecting a location of the printer carriage at a time of the detected power usage increase and determining, based on the detected location of the printer carriage, whether the print medium is damaged.

A printing apparatus includes: a head portion that discharges droplets toward a printing medium while reciprocating on the printing medium; and a controller that controls movement of the head portion during a printing operation such that a movement stop time of the head portion when a movement direction of the head portion is reversed at an endmost portion of a range in which the head portion moves is longer than the movement stop time of the head portion when the movement direction of the head portion is reversed on the printing medium.

A printing apparatus includes an apparatus body, a carriage, an encoder, a detection target member, a detector, and circuitry. The encoder detects an amount of movement of the carriage in a main scanning direction. The target member on the carriage has a cutout portion halfway in the main scanning direction. The detector on the body detects the target member. The circuitry controls a position setting operation for setting a home position of the carriage based on a detection result of detection or non-detection of the target member. The circuitry measures an output pulse of the encoder from when the detection result changes from detection to non-detection until when the detection result changes from non-detection to detection, and determines whether a measured value of the output pulse is equal to or greater than a predetermined value set based on a width of the cutout portion in the main scanning direction.

The printing apparatus includes a carriage having a print head mounted thereon, a carriage guide configured to guide movement of the carriage and to support the carriage, an optical scale member having an optical scale, an optical sensor mounting member having an optical sensor mounted thereon to read the optical scale, the optical sensor mounting member being fixed to a support surface of a support wall of the carriage, and a head portion of the fixing screw configured to be switched between a fixed state in which the optical sensor mounting member is fixed to the carriage and a release state in which the fixed state is released. The head of the fixing screw is located on a side opposite to the support surface with respect to the support wall when the optical sensor mounting member is in the fixed state.

The disclosure relates to a rendering apparatus, method and non-transitory machine-readable storage medium for determining a speed of a carriage during rendering of an image. A plurality of swaths of rendering fluid are deposited on a print target using a set of printheads moving across the print target. A temperature of a curing module is measured at a respective time of depositing each respective swath. An arrival time for each deposited swath to respectively arrive at the curing module is predicted. The speed of the carriage during depositing the plurality of swaths is determined based on the measured temperature of the curing module and predicted arrival time for each respective swath.

There is provided a liquid discharge apparatus including a conveyer, a carriage, a head and a controller. In a case of recording an image on a recording medium, the controller executes: obtaining information regarding a supply state of liquid from a liquid tank to the head in a case of executing each of recording passes; determining a moving velocity of the carriage with respect to each of the recording passes, based on the obtained information regarding the supply state; and adjusting a conveyance amount, by which the recording medium is conveyed in each of conveying operations, depending on moving velocities of the carriage determined with respect to two continuous recording passes, respectively, included in the recording passes, so as to adjust length in the conveyance direction of an overlap area in which recording areas by the two continuous recording passes overlap with each other.
