<p><P>PROBLEM TO BE SOLVED: To prevent erroneous notification. <P>SOLUTION: A one-bin stack paper sensor 34 detects existence of a recording paper sheet on a one-bin stack portion. A remaining paper sheet LED 54 is lit while the existence of the recording paper sheet on the one-bin stack portion is detected. In a case where double-sided printing is set to a printing format, by ejecting a part of recording paper sheets of which one side surfaces are printed onto the one-bin stack portion and by subsequently causing a one-bin paper ejecting roller to perform switch back for pulling the recording paper sheets thereinto, a conveyance controller 58 reverses surfaces to be printed to other side surfaces of the recording paper sheets. In the case where the double-sided printing is set to the printing format, the remaining paper sheet LED 54 is not lit even when the switch back is performed in a state that the existence of the recording paper sheet on the one-bin stack portion is not detected. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
