1. Measure to prevent damage to the fusing gear.
1.Model Name: SF-2118/ 21 16/1018/1016/2020/2120/1020/1 120
2.General: There have been problems reported of damage occurring to the key portion of the
fusing gear of the SF-2020 series during LTR, A4R, B5R, etc. copy paper lateral
feeding operations. The damage was caused by the temperature of the end of the heat
roller rising above the temperature whereby the material that the fusing gear is made of
becomes soft. As a measure to alleviate this problem the material of the gear has been
changed.

a measure to prevent paper delivery malfunctions.
1.Model Name: SF-2118/ 21 16/1018/1016/2020/1020
2.General: There were some problems of the projecting portion of the rubber roller section of the
paper delivery roller N2 in the base plate unit was ground away by friction, which
sometimes caused paper delivery malfunctions to occur. As a measure to alleviate this
problem, a change in the material of the roller has been carried out.

Swallow V2.8→V 2.9 List of change contents
No. Problem Movement after change was carried out.
A change has been carried out in the control of the
magnification display and lens movement control when
the zoom key is set to the ON position. (Patent recovery)
When the zoom key is depressed, the magnification
display is sequencially changed while the zoon key
remains in the depressed position. The lens movement
commences when the zoom key is set to the OFF
1
position, or when the 50% magnification position or the
200% magnification position is reached. Therefore, when
the zoom up key is depressed the magnification can be
changed until the key is released, or until 200%
magnification is reached., and when the zoom down key
is depressed the magnification can be changed until the
key is released, or until 50% magnifiction is reached.
A change has been carried out in the movement which
occurs when the interrupt key is depressed during copy
operations carried out in the ADF mode. (Patent recovery)
When the interrupt key is depressed during ADF mode
2
copy operations, the copy operations of the original
document which had already been fed are continued until
they are completed, after which the machine switces
over to OC mode even if there are still original document
pages left in the ADF to be copied.
When the machine changes over to the interrupt
reservation mode during ADF mode copy operations and
3
an empty paper tray is detected on the last copy page of
the final fed original document page, the main motor will
continue to run.
When the copy paper tray detection is set to LT and LTR
copy paper is detected, a jam does not occur and instead
the copy paper is fed into the machine at a speed of 18
4
pages per minute, which causes the temperature of both
ends of the fusing roller to rise, which can cause the
fusing gear to crack.
When the zoom key is depressed, the magnification will
automatically increase or decrease, but while the
magnification is changing (increasing or decreasing)
when the initial fixed magnification value (100% or 4R +
4E) is reached the magnification will stop changing
(increasing or decreasing). When the fixed magnification
value has been reached and the zoom key is released
and then depressed once again, the magnification will
increase (or decrease) until the next fixed magnification
value, where it will once again stop.
When the interrupt key is depressed and the machine is
changed over to the interrupt mode during ADF mode
copy operations, and there are still original document
pages left on the ADF tray, the ADF mode is maintained.
However, if there are not original document pages left on
the ADF tray the machine will be changed over to the OC
mode.
Furthermore, after the machine has been changed over
to the interrupt mode, if no original document is set on
the ADF and the OC cover is opened and closed, the
machine will automatically change over to the OC mode.
When the machine changes from the interrupt
reservation mode to the interrupt mode and an empty
paper tray is detected, the main motor no longer
continues to run in the interrupt reservation mode.
When the tray detection is smaller than the LT size and
the paper size being fed into the machine is larger than
B5, when the copy paper is finished being delivered a
jam shall be registered.
However, each counter will register one count for each
sheet of copy paper being delivered.
