Side Fan Level
1302 [2-Tray LCIT: Fan/Shutter]
Function
Adjusts the amount of air blown from the side fans to separate the sheets.
When to use
If double-feeds do not improve by setting 1301: [2-Tray LCIT: Paper Feed Mode] to [Prevent
Double Feed (Weakest Blow)], decrease the airflow in [Updraft Fan Level] in steps of 10%.
If paper misfeeds persist even after changing the air flow in 1301 [2-Tray LCIT: Paper Feed Mode]
to [Prevent Non Feed (Strongest Blow)], try increasing the air flow in steps of 10% along with the
value for the updraft fan level.
Sheets do not separate well because air does
not flow in between the sheets. Also, the sheets
tend to float up and result in double-feeds.
Vacuum Fan Level
1302 [2-Tray LCIT: Fan/Shutter]
Function

* If non-feeds occur due to low air suction power, increase the power.
When to use
If double-feeds do not improve by setting 1301: [2-Tray LCIT: Paper Feed Mode] to [Prevent
Double Feed (Weakest Blow)], increase the airflow in steps of 10%.
