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", Preparation.
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 RT5120) does not have the Pickup Assist function.
<If custom paper is used>
In [Advanced Settings] for the custom paper you are using, set 1312: [Main/3-Tray LCIT/Bypass] to [Off].
<If custom paper is not used>
In the [Machine: Paper Feed/ Output] group on the [Adjustment Settings for 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, select 1311: [3-Tray LCIT], and then set [Fan Setting] to [On]
Increase the value in [Fan Level] of 1311: [3-Tray LCIT].
<If custom paper is not used>
In the [Machine: Paper Feed/ Output] group on the [Adjustment Settings for Operators] menu, set 0301: [3-Tray LCIT: Fan Setting] to [On].
Increase the value in 0302: [3-Tray LCIT: Fan Volume Setting].
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 "Preparation" supplied with the machine.
Two-tray wide LCT (Vacuum Feed LCIT RT5120) is used.
The factory-set airflow of the wide LCT may not be strong enough to separate the sheets.
Increase the airflow.
Remove the paper, ruffle it, and reload it.
For details about ruffling the paper, see "Fanning the Paper", Preparation.
If the problem persists, load the sheets the other way up.
If the problem persists, select 1301: [2-Tray LCIT: Paper Feed Mode] in [Advanced Settings] for the custom paper you are using, and then set [Paper Feed Mode:Fan Level] to [Prevent Double Feed (Weaker Blow)].
If the problem persists, set [Paper Feed Mode:Fan Level] to [Prevent Double Feed (Weakest Blow)]
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 RT5120) does not have paper feed rollers.
