Disclosed are Power Encoder means for imprinting MICR characters on checks, with optical check-sensing means disposed along a check-transport path, including optical skew-sensor means.

Ribbon tracking technique with low-ribbon detection

Disclosed are Power Encoder means for imprinting MICR characters on checks, with optical check-sensing means disposed along a check-transport path, including optical skew-sensor means and a transport control arrangement for advancing checks past processing stations according to one or several 'velocity-profiles', depending upon the type and/or condition of the check.

Selectible transport-servo velocity profile for document transport

Document transport control including document velocity profiles

Disclosed are Power Encoder means for imprinting MICR characters on checks, with optical check-sensing means disposed along a check-transport path, including optical skew-sensor means including a pair of area-photo-sensor means, one on each side of the check whereby the differential output thereof indicates 'degree of skew'.
