Abstract
A method is disclosed for raising a base having media thereon. In an example embodiment, the method includes first raising a base having media thereon, ceasing the raising the base upon detecting the media, detecting an absence of the media, and second raising the base upon the detecting the absence of the media.
Claims26
A method, comprising:
- first raising a base having media thereon;
- ceasing the raising the base upon detecting the media;
- detecting an absence of the media;
- second raising the base upon the detecting the absence of the media.
A method, comprising:
- applying a first torque at a motor configured to move a base;
- detecting an object disposed on the base after the applying the first torque;
- applying a second torque at the motor in response to the detecting the object;
- detecting an absence of the object;
- applying the first torque upon detecting the absence of the object.
An image forming device, comprising:
- a print engine;
- a media handling device to advance media to the print engine;
- a controller for controlling the media handling device, the controller configured to apply a first duty cycle to the media handling device until detecting the media and to apply a second duty cycle to the media handling device upon detecting a presence of the media, the controller further configured to reapply the first duty cycle after applying the second duty cycle upon detecting an absence of the media.
A computer-readable medium having executable instructions for performing a method comprising:
- first raising a base having media thereon;
- ceasing the raising the base upon detecting the media;
- detecting an absence of the media;
- second raising the base upon the detecting the absence of the media.
A computer-readable medium having executable instructions for performing a method comprising:
- applying a first torque at a motor configured to move a base;
- detecting an object disposed on the base after the applying the first torque;
- applying a second torque at the motor in response to the detecting the object;
- detecting an absence of the object;
- applying the first torque upon detecting the absence of the object.
An image forming device, comprising
- a sensor for detecting presence or absence of media;
- means for controlling a media input tray based on output from the sensor.
An image forming device, comprising:
- a base configured to support media thereon;
- a sensor for detecting presence or absence of the media;
- a mechanism for raising and lowering the base in response to output from the sensor.
