Print media beam strength sensor

摘要

Beam strength and curl characteristics of sheets of print media change based not only on paper weight, but also on environmental conditions, such as humidity. Printers herein include a printing engine positioned to receive sheets of print media from a storage container. Sheet transport elements are positioned to transport the sheets from the storage through the printing engine. A sensor contacts one of the sheets, and the sensor detects a beam strength and curl characteristics signature profile of the sheet tested. Then, a processor (that is electrically connected to the sensor and the sheet transport elements) adjusts how the sheet transport elements contact the sheets (adjusts the angle, speed of, and force applied by, the sheet transport elements) based on the beam strength and curl characteristics signature profile.

主权项

1. A printer comprising:
a storage container shaped to store sheets of print media; sheet transport elements positioned to transport said sheets from said storage container; a sensor detecting forces while contacting one of said sheets; and a processor electrically connected to said sensor and said sheet transport elements, said processor determining a beam strength and curl characteristics signature profile of said one of said sheets based on said forces detected by said sensor, and said processor adjusts how said sheet transport elements contact said sheets based on said beam strength and curl characteristics signature profile.
