* If non-feeds occur due to low air suction power, increase the power.

If double-feeds do not improve by setting 1301: [Main/2-Tray LCIT: Paper Feed Mode] to [Prevent Double Feed (Weakest Blow)], increase the airflow in steps of 10%.

If double-feeds occur with paper with high porosity such as air-laid non-woven paper, decrease the airflow in steps of 10%.
