Reliable paper handling and a durable design are the hallmarks of the Panasonic KV-S4065CL Sheetfed Scanner. The ToughFeed paper feed mechanism and the Stapled Document Detection virtually eliminates stapled documents from being fed. The double-feed prevention system employs an ultrasonic sensor that detects the double feeding or originals during scanning and the Load Detection circuit allows the document hopper to automatically adjust its position to ensure reliable paper feeding. This innovative design has been proven effective even when the documents being scanned contain a mix of paper of different weights or thickness. Thanks to ToughFeed, optimum reliability is assured even when scanning high-volume documents. A 30,000 page per day scanning duty cycle and a compact desktop design make the Panasonic KV-S4065CL Sheetfed Scanner an excellent choice for businesses doing high-volume scanning.
