Media storage bin and method

A method of controlling a media storage bin having a guide member arranged to direct inserted media items downward, a base plate mounted below the guide member to hold inserted media items, a motor coupled to move the base plate up and down, and a controller, comprising:

• providing signals to the motor via the controller to move the base plate to a predetermined home position adjacent to the guide member upon startup, and
• providing signals to the motor via the controller to move the base plate upward to compress deformed inserted media items on the base plate until an input feedback signal reaches a predetermined level;
• wherein the motor is driven by a pulse width modulation (PWM) signal via a proportional integral derivative (PID) motor driver circuit, and
• wherein the input feedback signal is a PID/PWM gain of the motor.

A media storage bin, comprising:

• a guide member arranged to direct inserted media items downward;
• a base plate mounted below the guide member, the base plate arranged to hold a stack of inserted media items on a top surface thereof;
• a motor coupled to move the base plate up and down within an enclosure;
• and
• a controller coupled to control movement of the motor, the controller configured to provide signals to the motor to move the base plate upward to compress deformed inserted media items on the base plate;
• wherein the controller is configured to provide signals to the motor to move the base plate upward to compress deformed inserted media items on the base plate until an input feedback signal reaches a predetermined level;
• wherein the motor is driven by a pulse width modulation (PWM) signal via a proportional integral derivative (PID) motor driver circuit, and
• wherein the input feedback signal is a PID/PWM gain of the motor.
