When copying, the AE (Auto Exposure) Copy feature automatically optimizes reproduction quality based on the type of original you're duplicating. The convenient Photo/Film buttons allow you to make reprints of your photos and 35mm film without using your computer. And now, scanning: The unit's higher-resolution CCD technology enables you to produce exceptional 2400-dpi scans, with vibrant 48-bit color depth. You can simultaneously scan up to 6 frames of 35mm film (negatives or positives), or up to 4 mounted slides. Plus, advanced paper handling features are built in - such as two paper trays and 2 sided printing.
