Provided is an apparatus for stimulating cells using a 3D clinostat and ultrasonic waves in experiment equipment for studying adverse influences on a human body under microgravity and taking a countermeasure against the influences. Further, provided is a method of stimulating cells using a 3D clinostat and ultrasonic waves to study adverse influences on a human body under microgravity and to take a countermeasure against the influences.

Apparatus and method of stimulating cells using 3D clinostat and ultrasonic wave

A color image forming apparatus and a control method thereof, in which a transfer start position of a transfer belt is determined based on electric signals that correspond to a width of a position indicator provided on a transfer belt and are detectable during one rotation of the transfer belt even when noise occurs in output, thereby reducing the overall printing time.

Color image forming apparatus and control method thereof to determine whether to transfer toner image to a transfer belt

When the density of a toner image of a leading end of a printing sheet is no less than a predetermined reference density, a printing start time is delayed or printing data is deleted so that printing data is not printed in the leading end of the sheet. When the printing is performed in a state where a cover used for copying is opened, a printing start time is delayed or the printing data of the leading end of the printing sheet is deleted. Therefore, it is possible to prevent a fixing unit from being contaminated due to the toner image transferred to the leading end of the printing sheet.

Apparatus to prevent contamination of fixing unit in image forming apparatus and method of using such

A fuser cleaning apparatus and method of operating a fuser cleaning apparatus for use with an image forming device. Heat is efficiently transferred to a guide member of a fuser, thereby allowing for relatively easy performance of a cleaning operation of the fuser, since a heating roller of the fuser is heated by a heater while the heating roller is not in motion. It is also possible to prevent melted toner remnants from contaminating the heating roller since a sheet of paper which has waited at an entrance of the fuser is conveyed and passed between the heating and pressure rollers of the fuser after the heating roller is heated while it is not in motion.
