Depending on the cause of the problem, do one of the following:

Is the paper feed roller covered with paper dust?
  • Check the paper feed rollers of the LCT A3/A4, Multi Bypass Unit, and Cover Interposer Tray if they are installed.
  • 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. (Cleaning the Paper Feed Path)
Have you fanned the paper sufficiently to remove static cling?
  • Check the paper of the LCT A3/A4, Multi Bypass Unit, and Cover Interposer Tray if they are installed.
  • Double feeding may result if the paper is not ruffled properly.
  • Remove the paper, ruffle it, and reload it.
Is the Pickup Assist setting enabled?

This is for the LCT A3 only. 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.

If custom paper is used

In Advanced Settings for the custom paper in use, set Pickup Assist Setting to Off. (SP 1-977-001 to 100: LCT Pickup Assist ON/OFF Custom Paper 001 to 100)

If custom paper is not used

On the machine operation panel: Paper Feed/ Output group on the Adjustment Settings for Skilled Operators menu, set Pickup Assist Setting to Off. (SP 1-923-001 to 007: LCT Pickup Assist ON/OFF A3LCT Tray <number>)

Special or coated paper is used (LCT A3 only)
  • 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 in use, increase the value in Adjust Wide LCT Fan Level. (SP 1-975-001 to 100: LCT Tray Fan Duty Adjustment Custom Paper 001 to 100)

If custom paper is not used

On the machine operation panel: Adjustment Settings for Skilled Operators > Paper Feed/ Output > Adjust Wide LCT Fan Level > Increase the setting. (SP 1-920-001: LCT Tray Fan Duty Adjustment A3LCT Tray <number>)

  • Is the tab sheet holder attached?

Attach the tab sheet holder to prevent air from leaking at the trailing edge of the paper. This improves paper separation.

Special Paper
  • If the notch position adjustment of the PFU where double feeds are occurring is not set at the default position, you may have to adjust it again. Some types of paper may double-feed more often than others, requiring adjustment. (PFU Separation Roller Nip Adjustment)
