Detecting a black mark
<1D>H<53>H
• This command is valid only when a black mark is set in the
paper selection with DIP switch.
• Entering this command allows detection of a black mark.
• When a black mark is detected, the print paper is cut and
ejected.
• Also at the time of printer power on, a black mark is detected
and the print paper is cut and ejected. (Settable with DIP switch)
• If the 18-in. black mark cannot be detected, a mark detection
error occurs, causing BUSY and FAULT to be generated while
cutting and ejecting the print paper.
This command is ignored when normal thermal paper is set in
the paper selection with DIP switch.
