What to do if READY and MEDIA lamps blink simultaneously on Postek C168/200s Barcode Reader?

  Mary GutierrezAug 5, 2025
  If the READY and MEDIA lamps are blinking simultaneously on your Postek Barcode Reader, it could be due to several reasons: * The media sensor may not be detecting labels because the media hasn't been loaded correctly. Check the media loading. * The media sensor position may be incorrect and unable to detect the media gap or black line. Check the sensor position and calibrate it. If using continuous media, ensure the correct Media Type settings are chosen in the label software. * The media roll guides may not be firmly positioned against the media or have not been installed. Install the Media Roll Guides correctly and press them firmly against the media. * The media roll may have run out, so load a new roll of media. * The media may be jammed, so clear the jam.

  If only the READY lamp is blinking on your Postek Barcode Reader, it could indicate a serial I/O error. Check the DIP switches for the baud rate settings. Alternatively, it could be due to memory overflow, in which case you should restart or reset the printer.
