Abstract
Example implementations relate to adjusting print medium retrieval. For example, a system may include a printing device that may have a pick roller attached to a pick arm and a servomotor to apply torque to the pick roller. The system may further include a controller associated with the servomotor to determine a measured position of the servomotor relative to an intended position of the servomotor in a particular time frame during the print medium retrieval. The controller may further determine adjustment of the print medium retrieval based on comparison of a pulse width modulation (PWM) magnitude in adjacent time frames.
