ABSTRACT:
A paper feed controlling device for a printer includes a feeding apparatus for feeding recording paper along a predetermined path. The size of the image to be printed with toner particles is determined. A detector determines the size of the paper as it travels along a predetermined path. The image size and the detected paper size can be compared. A controller can control the feeding apparatus prior to the completion of the detection of the size of the paper so as to prohibit the initiation of a subsequent feeding of recording paper and when it is determined that the image size is inappropriate. Toner particles can be cleaned from a photosensitive drum in preparation for a subsequent printing operation.
