MEASURE TO ALLEVIATE PROBLEMS OF JAMS IN THE
FUSING SECTION WHICH OCCUR DURING DOUBLE-SIDE
COPY OPERATIONS.
1.Model Name: SF-2116/1016/2118/1018/2020/1020/2216/1116
2.General: There have been problems of jams occurring in the fusing section during double-side
copy operations due to factors such as the quality of the copy paper and the humidity.
The following information concerning the action that has been carried out to alleviate
this problem is hereby reported.
Note:
Double-side copy operations carried out on the models listed above from the copy
paper cassette are not included in the specifications. As a result, even if the action
described in this Technical Report is carried out it does not mean that a change has
been carried out in the specifications (in other words, it does not mean that the
machines will be changed so that the function of double-side copy operations using the
copy paper cassette feed will have been made possible). As a result, when double-side
copy operations are carried out, it will be necessary to carry them out using manual
copy paper feed after correcting any curling of the copy paper, and it will therefore be
necessary to exercise caution to insure that there are no misunderstandings with the
customers.
<Symptoms>
There have been problems of jams occurring in front of the fusing section during
double-side copy operations.
<Cause>
When single side copies are made, curling sometimes occurs in the copy paper as due
to paper quality and humidity factors. If double-side copy operations are carried out
without correcting the curling of the copy paper, there is a possibility of jams occurring
in front of the fusing section.

<Action>
The addition of the following parts listed below has been carried out. This action has
been carried out as a measure to improve the transport performance of the copy paper
in front of the fusing section.
<Parts name> <Parts code> <Q'ty>
Fusing front sheet A PSHEP4620FCZZ 1
Fusing front sheet B PSHEP4621FCZZ 1

<Attachment procedures>
<1> Disengage the fusing section from the machine.
<2> Remove the fixing screws (XHBSD30P06000) of the fusing unit and then remove
the fusing cover (PCOVQ1278FCZZ).
<3> Carry out attachment procedures of the new parts to the fusing cover.
Caution:
Please refer to the figure shown below for details concerning the attachment
standards. When attaching the new parts to the fusing cover the attachment
surfaces of the fusing cover should be carefully wiped with alcohol.

Fusing front sheet B
Care should be exercised so that fusing front sheet B, the fusing front guide
sheet, and fusing front sheet A do not ride up on the ribs of the fusing cover.

The attachment size of each
sheet with regards to the
attachment standards marked
in the figures shown to the
right should be a maximum of
0 mm in the "+" direction and
0.5 mm in the "-" direction.
Fusing front sheet A/B:
The fusing front sheets should be attached as shown in figure 1 with the end
of the ribs of the fusing cover being in alignment with the cut-away section R
of each sheet.
Fusing front guide sheet:
The fusing front guide sheet should be attached as shown in figure 2 with the
end of the fusing front guide sheet in alignment with the curved portion of the
fusing cover.
<4> The upper guide sheet should be attached to the fusing upper guide.
Please refer to the figure shown below for details concerning the attachment
standards.

Attachment differential:

Caution:
If there is any damage to the upper guide sheet in the section where the copy
paper passes through the copy paper can become snagged. After attachment
operations have been completed the surface of the section should be carefully
checked to make sure that there are no places where the copy paper can
become snagged.
<5> The fusing upper guide (Qty: 2) to which the upper guide sheets have been
attached should next be attached to the fusing upper frame. It is important to
note that the attachment holes in the fusing upper guide are long holes, and the
method of attachment for the AB series machines is different than that for the
inch series machines.
AB Series:
The fusing upper guide to be attached to the F side should be moved toward the
F side and then attached, and the fusing upper guide to be attached to the R
side should be moved toward the R side and then attached.
3/7
Inch Series:
The fusing upper guide to be attached to the F side should be moved toward the
R side and then attached, and the fusing upper guide to be attached to the R side
should be moved toward the F side and then attached.

Caution:
Care should be exercised to insure that the fusing front sheet A and the fusing
front sheet B do not become sandwiched in the gap between the fusing frame
and the fusing cover.

<7> Attach the fusing unit to the machine by carrying out steps <1> and <2> in
reverse order.
<8> Remove the drum frame unit from the machine.
<9> Attach the new parts to the bottom surface of the DR frame lower
(LFRM-0843FCZZ).
Caution:
Please refer to the figure shown below for details concerning the attachment
standards. (The diagram shown below depicts the drum frame unit from the
bottom direction.) When attaching the new parts to the DR frame lower the
attachment surfaces of the fusing cover should be carefully wiped with alcohol.
<10> Attach the drum frame unit to the machine.
3.Action: Field action only.
