What is Toughfeed?
ToughFeed is a name given to a group of functions that are featured on Panasonic scanners to ensure a smooth supply of paper into the scanner for efficient scanning always.*
ToughFeed helps to prevent the unnecessary interruption of scanning work due to an equipment malfunction or double feeding that can otherwise result in un-scanned sheets, thus ensuring high work efficiency.
* Available on select models only.
Stapled document detection
Preventing damage to the scanning glass - Multiple sensors are used to detect various types of stapled documents, and to immediately stop the scanner when stapling is detected. This minimizes damage to both the document and the optical glass.

Ultrasonic double-feed detection
Ultrasonic sensors detect double feeds. Certain models* have 3 or more ultrasonic sensors to cover a larger area of the document for versatile detection of things like sticky notes or small documents mixed among regular-sized documents
* 5 Sensors: KV-S8147, 3 Sensors: KV-S8127, KV-S4085CW.
Intelligent feed control
Multiple sensors check the paper feed condition and automatically adjust the roller pressure to ensure that documents of various thicknesses are accurately fed. This makes it more reliable and accurate than conventional methods that use only the feed mechanism.
Superior roller mechanisms
The paper feed rollers separate from the paper each time a sheet is fed, so the tendency to double-feed caused by the paper feed roller pressure is reduced, even when feeding paper of different thicknesses. Any paper sliding is also detected and the double feed prevention roller pressure is adjusted to prevent the paper from slipping and jamming.
