Preventing Duplex Section Jam (J40)
he Trailing Edge Tapping Stopper controls the
movement of the Trailing Edge Tapping Guide.
Due to the material of the Stopper (sponge), the
Guide may bounce and cause the lead edge of
the paper to make contact with the Guide. As a
result, a paper jam may occur.
To prevent this problem, remove one Stopper
from each side of the Guide. One Stopper on
each side will remain. As a permanent measure,
the thickness of the Stopper will be changed
from 2mm to 3mm eliminating the need for two
stoppers on each side.
