Printing Equipment

Sense presence of various printing forms


  • ・For various printing forms, sense that the printing paper is in the predetermined position

Issues & Requests

  • ・Want to stably detect various types of printing papers.
  • ・Need a sensor detecting no background objects.

There are various types of printing papers available, for example, transparent or variously colors. If using a general sensor, sensitivity adjustment may be needed for each different colored form or it may detect the background when sensing a transparent sheet.


  • ・Adopted model:
    Light convergent reflective sensor B5W-LB2112-1
  • ・This sensor is optically designed to detect objects with low reflectivity, such as transparent plastic and black. This is useful for detecting various types of printing paper (glossy, non-glossy, transparent, etc.).
  • ・This sensor contributes to the downsizing of the equipment because there is no influence from background objects in the predetermined non-sensing range.

For details, refer to B5W-LB Series: Light Convergent Reflective Sensor User’s Manual.

  • Distance Characteristics for
    Various Reflective Objects
  • Receiver Output-Sensing Distance Characteristics

*The possibility of detecting the object varies depending on the sensing object or how to install the sensor.
Be sure to conduct sufficient evaluation using the actual devices before staring practical use.
