2.3.5 Pre-Last Original Detection

Pre-last original detection makes use of the pre-last original sensor (S8). Detection is ex-

ecuted on small-size originals only. The DADF is designed to send the second original to the

separation assembly after it has picked up the first original (small-side). At that time, if no

original covers the pre-last original sensor (S8), the dada will assume that no original will

follow, and communicates as such to the copier.

Small-size: A5, A4, B5, STMT, LTR
