Vacuum Feed LCIT
Like the paper feed units of offset printer systems, the Vacuum Feed Large Capacity Input Tray employs
the air-assist pick-up feature.
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 sheet 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.
• Return fan: Sucks air beneath the floating sheet in downward direction to prevent excessive suction
by the suction fan in upward direction that may cause double-feeds.
Each fan level is made adjustable to prevent non-feeds and double-feeds in 1301: [Main/2-Tray LCIT:
Paper Feed Mode].
