Abstract:
The present subject matter describes determination of amount of print media present in an input tray of a printing system. In an example implementation of the present subject matter, a current operating torque of a motor that moves a pick arm for drawing print media from the input tray is monitored. The current operating torque is monitored while the pick arm is moved between a rest position and a pick-ready position. Based on the monitored operating torque, it is determined whether amount of print media present in the input tray is one of below and above a predefined amount of print media.
