The unattended low-resolution scanning station (14) generates a plurality of active image area signals indicative of the active image areas and borders in a plurality of light passing documents. The unattended high resolution line scanning station (18) includes a high resolution line scanner (20) that responds to the individual ones of said plurality of active image area signals. The high resolution scanning station (18) automatically focuses the high resolution line scanner (20) on only the active image area of said light passing documents.</p> |
