摘要： A printer includes a conveyor to convey a tape having a plurality of marks in a conveyance direction, the marks including a first mark, and a second mark formed downstream of the first mark in the conveyance direction, a print head to print an image on the tape, a reflection sensor to detect the marks on the tape by emitting light toward the tape and receiving reflected light from the tape, and output a detection signal according to the reflected light when detecting the marks, and a controller. The controller is configured to set a threshold to be variable based on a level of the detection signal when the reflection sensor detects the second mark, and identify a position of the first mark based on a result of comparison between the threshold and a level of the detection signal when the reflection sensor detects the first mark.

摘要： A printing apparatus includes: a conveyor configured to convey a web print medium with holes arranged at a predetermined pitch in a conveyance direction; a printer configured to perform printing on the web print medium conveyed by the conveyor; a detector configured to detect the holes; and a controller. The controller is configured to drive the printer to start printing on the web print medium based on a timing at which a count value of the holes detected by the detector from start of conveyance of the web print medium by the conveyor reaches a setting value of a number of the holes located from the detector to a print start reference position on the web print medium at the start of conveyance of the web print medium by the conveyor.

摘要： Scan printing systems and methods for reducing banding artefacts of an image printed on a substrate, including a substrate feeder assembly, a printhead adapted to print an encoder pattern on the substrate, a sensor, and a controller. The controller performs a feedback cycle of positioning the substrate relative to the printhead and instructs the printhead to print a band of the image when the encoder pattern has reached a target position. The controller repeats the feedback cycle of positioning the substrate relative to the printhead and instructs the printhead to print a subsequent band of the image until the entire image is printed on the substrate.

摘要： Technology enabling accurately detected marks on a print medium according to the type of print medium is provided. A printer 1 has a media type identifier 110 that determines the type of medium; a mark sensor 76 that projects light and detects a mark on the medium; and an emittance controller 111 that sets the emittance level of the light the mark sensor 76 projects. The printer 1 can change the operating mode according to the type of medium M identified by the media type identifier 110. In the white medium mode, the mark sensor 76 detects a mark MR with the emittance level set to a white medium emittance level. In the non-white medium mode, the mark sensor 76 detects a mark MR with the emittance level set to a non-white medium emittance level, which is higher than the white medium emittance level.

摘要： In one example in accordance with the present disclosure, a printing system is described. The printing system includes multiple print engines to form printed marks on a substrate. Each print engine prints non-sequential pages of a print job. A sensor of the printing system detects, for each page, a trailing edge gap size and a leading edge gap size. A controller of the printing system, based on a difference between trailing edge gap sizes and leading edge gap sizes for a set of pages of a print job, adjusts a printing operation to equalize subsequent trailing edge gap sizes and leading edge gap sizes.

摘要： An image forming apparatus includes a conveyor to convey a recording medium; an image forming device including a recording head to form a test pattern including a first mark and a pair of second marks; an imaging device; and a processor. The processor includes a pattern forming unit to cause the image forming device to form one of the first and second marks and form the other after the conveyor conveys the recording medium by a predetermined conveyance amount, a position detector to detect positions of the first and second marks in the captured image, a ratio calculator to calculate a ratio between a distance between the second marks and deviation of the first mark in the captured image, and a distance calculator to calculate an actual distance of the deviation based on a theoretical distance between the second marks and the ratio.
