Abstract
An image forming apparatus including an image forming device, a sensor, and a processor. The image forming device is to form an image on recording medium. The sensor is to irradiate light to the recording medium and detect an amount of light transmitted through the recording medium and an amount of light reflected from the recording medium, resulting in a control of a printing operation of the image forming device based the amount of light transmitted through the printing medium and the amount of light reflected from the printing medium.
Claims13
An image forming apparatus comprising:
- an image forming device to form an image on a printing medium;
- and
- a sensor to,
- irradiate light to the printing medium,
- detect an amount of light transmitted through the printing medium, and
- detect an amount of light reflected from the printing medium, resulting in a control of a printing operation of the image forming device based the amount of light transmitted through the printing medium, the amount of light reflected from the printing medium, and a distance between a light emitting device and a light receiving sensor.
