  • 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.
