A system for detecting the level of a media supply in a printer has a frame having a support for seating the printer thereon. A first light source is positioned on the support and is energizable to direct a first beam of light into the printer. A first detector is positioned on the support and provides an analog signal in response to reflection of the first beam of light from within the printer. A control logic processor is in signal communication with the first detector and compares the analog signal to a stored/predetermined value and reports a low media condition according to the comparison.

It is one object of the present invention to provide a thermal history estimation apparatus, a thermal history estimation method and a thermal history estimation program that can estimate variation in thermal history within a plane of a sheet heated by a heating apparatus. The thermal history estimation apparatus includes a first acquisition unit that acquires color information on a sheet plane heated by the heating apparatus, and a first estimation unit that estimates information on variation in thermal history on the sheet plane based on the acquired color information.

A sheet conveying device, which is included in an image forming apparatus, includes a pair of rollers configured to convey a sheet in a sheet conveyance passage, a detector configured to optically detect an attitude of the sheet, one of a rotation device to rotate the pair of rollers in a direction parallel to a plane of the sheet and a moving device to move the pair of rollers in a width direction, and a controller configured to correct the attitude of the pair of rollers at a time interval, based on a detection result obtained by the detector. The controller performs the correcting operation by setting, according to reflectance of the sheet, at least one of a light emission time of the detector, the time interval of the correcting operation, light emission intensity of the detector and a conveying speed of the sheet.
