Previous
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.
The paper is curled.
Double feeding may occur if the paper is curled.
Type of curl
Face curl: The set paper is warped upward.
Back curl: The set paper is warped downward.
Measurement of curl
Load one sheet of paper on a flat surface, apply the scale to the leading edge of the paper, and
measure the curl at the four edges. The maximum value is the curl value.
Curl standard
Acceptable curl amount varies depending on the basic weight of the paper.
Paper weight | Curl amount |
|---|---|
Paper Weight 0 - 6 | Face curl: 10 mm Back curl: 10 mm |
Paper Weight 7 | Face curl: 10 mm Back curl: 5 mm |
Paper Weight 8 | Face curl: 10 mm Back curl: 3 mm |
Paper Weight 9 | Face curl: 10 mm Back curl: 0 mm |
Correcting curl
Place the curled surface down on a flat surface.
Hold the end of the paper and straighten it in the opposite direction to the curl direction so that the paper is rounded.
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.
Adjust the airflow.
To adjust the following settings, pre-register the type of paper in use as a custom paper. For details about registering custom papers, see "Specifying a Custom Paper", Preparation.
If the jam code J099 appears more than three times, in [Advanced Settings] for the custom paper, select 1301: [Main/2-Tray LCIT: Paper Feed Mode], and then set [Paper Feed Mode:Fan Level] to [Prevent Double Feed (Weaker 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.
