Depending on the cause of the problem, do one the following:
Paper with high paper-to-paper adhesion is used.
Paper with high paper-to-paper adhesion may be wrongly detected as double feeding.
Ruffle the paper well before use.
For details about ruffling paper, see "Fanning the paper", Preparation.
An envelope is being used.
The seams of envelopes may cause double feeds to be erroneously detected.
Disable the double feed detection.
<If custom paper is used>
Select [Machine: Paper Feed / Output] in [Advanced Settings] for the custom paper in use, select 1341: [Jam Detection] and set [Double Feed Detection] to [Off].
<If custom paper is not used>
In the [Main Unit: Paper Feed/ Output] group on the [Adjustment Settings for Operators] menu, set 0301: [Double Feed Detection] to [Off].
In cases other than those described above, the double feed detection sensor may be soiled with paper dust or other fragments and erroneously detecting double feeding. Contact your service representative.
Disabling double feed detection may reduce print image quality or cause blank sheets to be delivered.
