Zusammenfassung:	The method involves timing reflex light box (8) outside the alignment zone of the guide sheet (3) and before the transfer and/or reception of the sheet (6) from the corresponding cylinder (1) or drum (2). When a sheet is present, the light beam of the transmitter is reflected from the sheet. It brings up the receiver, signalling a valid sheet. If there is no sheet present, the light beam is diverted by the corresponding cylinder or drum so that no reflection falls on the receiver, and the problem is thus detected.
