When documents are set on the document set tray in the auto selec-
tion mode of paper/copy magnification ratio, the document size is
detected and p aper and t he copy mag nificat ion ratio ar e automat ically
selected. When different sizes of documents are set, the max. size is
detected. Th e do cum ent wi dth is det ecte d by the doc ume nt w idth s ensors (W1, W2, W3), and the document length is detected by the document length s ensors (L1, L2 ) t o i dentify the docum ent size. Judg em ent
of the docume nt size is made in a certain t iming after detecting the
document with the document set sensor (W0).
