Double Feeding
Take the appropriate action according to the cause of the problem.
There is paper dust on the paper feed roller.
Check the paper feed rollers of the A3/A4 LCTs, the multi bypass unit, and the cover interposer
tray.
Paper dust weakens the traction of the paper feed roller, causing paper slipping or insufficient
separation.
Cleaning the paper feed roller to maintain traction and prevent double feeding. (
Paper is not fanned sufficiently.
Check the paper in the A3/A4 LCTs, the multi bypass unit, and the cover interposer tray.
Double feeding may result if the paper is not ruffled properly.
Remove the paper, ruffle it, and reload it.
Pickup Assist Function may cause double feeding (A3 LCT only)
With the A3 LCT, the Pickup Assist function may cause double feeding of coated paper. You can avoid
double feeding by disabling this function.

Is the tab sheet holder attached?

paper separation.

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. (For details, refer to "PFU Separation Roller
