MEASURES CARRIED OUT TO PREVENT COPY PAPER
JAMS AND DOUBLE FEEDING IN THE CENTER TRAY.
This action was previously reported and explained in T/R DTE-230. A claim was
received, however, to the effect that the explanation concerning the measure carried out
to prevent copy paper jams in the center tray was difficult to understand, and the action
is hereby once again reported and explained.
No. : DTE-278
1.Model Name: SD-2060/3062
2.General: There were reports of some problems of folded corners on the leading edge of the copy
paper and copy paper jams which occurred in the center tray in cases of large copy
paper curls during back side copy operations. There were also reports of some
problems of double feeding of copy paper due to the effects of static electricity. As a
measure to alleviate these problems, the action described below has been carried out.
3.Description: (1) As described in figure-1 shown below, the end portion of the blow duct is positioned
so that the air is split on the paper guide from behind. When upward curling copy paper
is fed, however, the copy paper sometimes gets caught on the blow duct causing folded
corners on the leading edge of the copy paper which results in copy paper jams. As a
measure to alleviate the problem described above, a change in the shape of the blow
duct has been carried out so that the copy paper does not become caught on it. In
accordance with the change in shape that was carried out on the blow duct, a change
has also been carried out on the shape of the blow duct mylar sheet.
Figure-1: The performance of the machine concerning upward curling copy paper has
been improved by enlarging the taper on the bottom portion of the blow duct.

• A change has been carried out in the contact angle of the discharge brush and the
copy paper. As an effect of this change the discharge of static electricity is facilitated,
which results in the alleviation of problems of copy paper double feeding.
• A change in the method of attaching the discharge brush will result in the hairs of the
brush coming in contact with the FN and RN of the rear end sheet. A change in the
attachment method of the FN and RN of the rear end sheet has therefore been carried
out.
• A s a result of the change in the method of attachment of the FN and RN of the rear
end sheet, the ground cannot be reached between the frame and the FN and RN of the
rear end sheet. As a measure carried out to alleviate this problem, a change has been
carried out in the shape of the FN and RN of the rear end sheet so that it can be
tightened simultaneously with the discharge brush, which allows the ground between
the frame and the FN and RN of the rear end sheet to be reached.
(The FN and RN of the rear end sheet is an electrically conductive mylar sheet.)

• A discharge sheet fixing plate and a lift bearing discharge sheet has been added to
the F/R section of the lift slide plate. This change has been carried out as a measure to
diminish the charge of static electricity on the copy paper.
