Features Multiple Methods for Document Feeding ● Scan multipage documents at up to 20 pages per minute (for singlesided documents) using the built-in feeder. The scanner can detect documents that are loaded into the feeder and begin scanning automatically using the auto-start function. ● Use the flatbed to scan documents that cannot be scanned through the feeder (thin documents, documents that do not feed smoothly, magazines and thicker documents, etc.). ● Feed and scan up to 15 business cards at a time using the built-in business card feeder. Easy Scanning with Job Functions Start scan procedures using the buttons on the operation panel without having to open an application program. Wide Range of Black and White and Full Color Scanning ● Scan documents in 24-bit color or 256-level grayscale. ● Scanning in black-and-white (binary) is also possible. Use the advanced text enhancement modes to clarify text when scanning documents with dark backgrounds or faint text. ● Use the color smoothing mode to reduce the occurrence of moiré patterns when scanning color images from a magazine, for example. Prescan Function At the start of scanning, this function prescans the first page of a document and pauses so that you can use the first image to adjust the brightness and contrast before scanning resumes. Energy Efficient Design This scanner conforms to international Energy Star program standards, and enters a sleep mode when it is not scanning. Variety of Image Processing Options ● Auto Paper Size Detection Detect the document page size while scanning. This also removes the blank space that surrounds an image when a document of a non-standard size is scanned. Standard-Sized Document Scanning Auto Size Detection Scanning ● Text Orientation Recognition Detect the text orientation on each document page, and rotate the scanned image in 90-degree increments as necessary for normalization. (This function may not work properly depending on the document type.) Landscape Document (Scanned Vertically) Image after Text Orientation Recognition ● Deskew Detect whether a document has been fed askew image, and straighten the image as necessary.
