Abstract
A recording media smoothness detector includes a sensor and a calculator. The sensor includes a light source to emit light toward a recording medium and a light detector to detect an amount of light reflected by the recording medium. The calculator includes a first memory to store an initial output value of the sensor and a second memory to store a decreased output percentage of the sensor relative to the initial output value per number of recording media detected. The calculator is configured to calculate a decreased output amount of the sensor from the decreased output percentage of the sensor per number of recording media detected, according to a number of recording media detected by the sensor, to adjust a luminosity of the light source based on the calculated decreased output amount of the sensor and determine a type of the recording medium based on an output of the sensor after the adjustment of the luminosity of the light source and based on the number of recording media detected by the sensor.
