  • Patent number: 10421298
    Abstract: 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.

  • Patent number: 10406822
    Abstract: A quick release print head includes a heating block, a nozzle tube and a connecting tube. The nozzle tube is inserted in the heating block. One end of the nozzle tube has a nozzle and the other end is extended with an extension tube exposed to the heating block. The connecting tube is connected with the extension tube. Whereby, the extension tube extended from the nozzle tune is exposed to the heating block so that the nozzle tube disposed near the heating block cannot be disassembled. Thus, a process of replacing components by heating a nozzle can be bypassed, and advantages of quick disassembly and easy maintenance of the print head can be achieved.
