Depending on the cause of the problem, do one of the following:
Have you ruffled the paper sufficiently?
Double feeding may result if the paper is not ruffled properly.
Remove the paper, ruffle it, and reload it.
For details about ruffling the paper, see "Fanning the Paper", About This Machine.
The edges of the sheets are rough.
Turn the sheets the other way up or smooth the edges before loading.
Is the Pickup Assist setting enabled?
If the Pickup Assist function operates too much, it may cause double feeding with coated paper.
By disabling the Pickup Assist setting, you can prevent double feeding.
The two-tray wide LCT (Vacuum Feed LCIT RT5100) does not have the Pickup Assist function.
<If custom paper is used>
In [Advanced Settings] for the custom paper you are using, set 110: [Pickup Assist Setting] to [Off].
<If custom paper is not used>
In the [Machine: Paper Feed/ Output] group on the [Adjustment Settings for Skilled Operators] menu, set 0303: [Pickup Assist Setting] to [Off].
Three-tray wide LCT (LCIT RT5090) is used.
Is the airflow strong enough?
The factory-set airflow of the wide LCT may not be strong enough to separate the sheets.
Increase the airflow.
<If custom paper is used>
In [Advanced Settings] for the custom paper you are using, set 108: [Wide LCT Fan Setting] to [On]
Increase the value in 109: [Adjust Wide LCT Fan Level].
<If custom paper is not used>
In the [Machine: Paper Feed/ Output] group on the [Adjustment Settings for Skilled Operators] menu, increase the value in 0301: [Adjust Wide LCT Fan Level].
Is the tab sheet holder attached?
By attaching the tab sheet holder, you can prevent air from leaking at the trailing edge of the paper and improve separation.
For details about attaching the tab sheet holder, see "About This Machine" supplied with the machine.
Two-tray wide LCT (Vacuum Feed LCIT RT5100) is used.
The factory-set airflow of the wide LCT may not be strong enough to separate the sheets.
Increase the airflow.
In [Advanced Settings] for the custom paper you are using, set 118: [Paper Feed Mode (Adjust Fan Level)] to [Modrate Dble Fd Red. (Lower)].
If the problem persists, set 118: [Paper Feed Mode (Adjust Fan Level)] to [Max Dble Fd Reduc. (Lowest)].
If the problem persists, increase the value in 112: [Blower Fan] by 10%.
If the problem persists, increase the value an additional 10% in 112: [Blower Fan].
If the problem persists, set 117: [Switch Paper Load Upper Limit] to [Low].
Is the paper feed roller covered with paper dust?
Paper dust may decrease the traction of the paper feed roller and result in double feeding due to paper slippage or insufficient separation.
Cleaning the paper feed roller will restore traction and so prevent double feeding.
For details about cleaning the paper feed roller, see Cleaning the Paper Feed Path.
For details about removing the paper feed roller, see the Replacement Guide.
The two-tray wide LCT (Vacuum Feed LCIT RT5100) does not have paper feed rollers.
