To minimize the feeding noise from the LCT, a noise absorber seal has been stuck on the reverse
side of each side fence (three feed trays, front and rear: total 6 pcs).

When the LCT was connected to the 105 cpm machine in a laboratory test, noise was
generated from the thrust gap between the relay clutch and idle gear because of the
higher paper feed speed. To correct this, a felt wick spacer has been added and one
retaining ring has been removed. The idler gear (AB013000) is now supported by the
stopper plate instead of the removed retaining ring.

When the LCT was connected to the 105 cpm machine in a laboratory test, the timing belts
tended to slip off the idler pulley. To correct this, a flange and a flat washer have been
added to each tension bracket (B3031571, page 27, index 14 and page 29, index 15).

If Tray 6 (2550-sheet tray) with a large amount of paper is forcibly pushed into the LCT
main body, the rear LCT side plate may be temporarily bent. This may cause the side plate
bracket to touch the paper height sensors, which can sometimes result in a short circuit or
damage to the sensors. To correct this, a stopper extension has been added to the side
plate bracket. Therefore, even if the above situation occurs, the side plate bracket is
stopped by the stopper extension. This will ensure that the bracket does not touch the
sensors.

When changing the paper size, operators have to change the position of the end fence
(Knob Screw with Rubber Tube). When the operator installs the end fence in the hole in
the paper guide fence incorrectly, the top of the end fence is higher than normal. The end
fence may tend to be broken by the tray front cover when the tray is pulled out. To improve
the durability of the end fence, the production machines have been modified as follows:
1. The knob screw has been made shorter.
2. The rubber tube has been made 1 mm longer.
Changed from 8.5 mm to 5.0 mm
Changed from 4.5 mm to 3.5 mm

3. The diameter of the holes for inserting the end fence (Knob Screw with Rubber Tube)
in the Paper Guide Fence has been changed from 4 mm to 5.5 mm.
Note: When replacing any of the old parts in the field, install all three new parts as a
set.
