An automatic teller machine (ATM) validates checks presented to it by printing on the check. It is desirable that validation be printed in the same area on all checks to facilitate later manual processing. It is therefore desired to detect the orientation of the check prior to validation and return improperly oriented checks to the ATM user for re-insertion. The present embodiment performs this function by means of a pair of optical sensores which detect the presence of a specific field of the MICR characters on a properly-oriented check. Fig. 1 shows that check 1 is inscribed with magnetic characters on either line 2 or line 3. It is seen that as the check moves in the direction shown, it will pass infrared photodetectors 4 and 5 which are positioned to scan lines 2 and 3, respectively.
