2. Printing Process

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].
