The LCIT employs the air-assist pickup, similarly to the paper feed units of offset printers.
In addition to the air blown from the right/left sides, sucking air to pick up the top most sheet of the stack enables smooth feeding without double-feeds and non-feeds even with coated stocks and super smooth surfaced stocks that tend to stick together, providing good feed performance.
Functions of each of the fans are as follows:
Updraft fan: Blows air to the leading edge to float up the sheet.
Separation fan: Blows air in between the top most and second sheet for separation.
Side fan: Blows air from the right/left sides to fan the paper.
Suction fan: Sucks air to adhere the sheet to the suction belt for feeding.
Each fan level is made adjustable to prevent non-feeds and double-feeds in 1301: [2-Tray LCIT: Paper Feed Mode].
