Ink-jet printing device

Abstract

The invention relates to an ink-jet printing device comprising a transmission unit, a tail end detection unit, a correction unit, a generation unit, an accumulation unit, an identification unit and a second calculation unit, wherein the transmission unit is used for transmitting a recording medium; the tail end detection unit is used for detecting a current position of a tail end in the transmission direction of the recording medium transmitted by the transmission unit; the correction unit is used for correcting the current position of the tail end into a tail-end correction position; the generation unit is used for generating a layout of images to be recorded; the accumulation unit is used for accumulating transmission capacity of the recording medium transmitted by the transmission unit during intermittent drive; the identification unit is used for identifying information of the recording medium; and the second calculation unit is used for calculating a calculation position of the tail end on the basis of the transmission capacity accumulated by the accumulation unit and the recording medium information identified by the identification unit. Through the ink-jet printing device disclosed by the invention, images are cut by detecting the tail end of printing paper according to the tail end of the printing paper, thus ink can be prevented from being attached on a belt; in addition, individual difference, such as sensor fluctuation and installation fluctuation can be overcome by working out the quantity influenced by the variable stroke of a filler.

Description

technical field [0001] The invention relates to a printing device, in particular to an inkjet printing device. Background technique [0002] In recent years, printer technology has advanced rapidly due to the development of personal computers. A printer prints an image on paper based on image information. The printing apparatus for printers that has attracted the most attention in recent years is the inkjet printing system. Inkjet printing systems that print images by ejecting ink from a printing head onto paper have become popular. The advantages of inkjet printing systems are that inkjet printing systems can print high-resolution images quickly and are better than other printing methods in different aspects, such as running costs and quietness. [0003] Some inkjet printers write images on the printed paper by using a charged belt to attract the paper and make sure the printed paper is flat. In this type of inkjet printer, it is necessary to prevent ink from adhering t...

Problems solved by technology

[0007] However, in these schemes, when the sensor performance degrades and the detection results are wrong, it is impossible to obtain accurate tail position

[0008] In addition, the above-mentioned solutions only provide detection of the tail position of the paper conveying direction, and fail to fully detect the printable area of ​​the paper
