No. : DTE-099
1. Prevention of copy image disalignment during printing.
1.General: Copy image disalignment sometimes occurs during the paper gripping process of the
heat rollers. To prevent this the pressure of the heat rollers has been reduced.
2.Cause: The above problem is caused by the impact during the paper gripping process of the
heat rollers.
3.Description: To reduce the pressure of the heat rollers and thus make the paper gripping process
run more smoothly, a collar has been added. (The collar has been added to both front
and rear sides of the fixer unit.)
Added collar
(PCLR-0391FCZZ).
4.Effective time: (Factory action)
From mid-July, 1993.

2. Prevention of LCD corner fading by changing the liquid crystal attachment plate.
1.General: A plastic washer with a thickness of 0.5 mm had been inserted between the LCD and
the liquid crystal attachment plate. To prevent fading of the liquid crystal display
corners, the shape of the liquid crystal attachment plate has been changed, and the use
of the washer has been discontinued.
2.Cause: The above change has been implemented as a permanent measure to prevent fading
of the LCD corners.
3.Description: Instead of using the plastic washer, the liquid crystal attachment plate has been tapered
0.5 mm. The parts codes affected by this have been changed accordingly.
A plastic washer with a thickness of 0.5
mm had been inserted between the LCD
and the liquid crystal attachment plate, but
the liquid crystal attachment plate has
been tapered 0.5 mm, and the use of the
plastic washer has been discontinued.

3. Prevention of wrinkling during back side copying.
1.General: Wrinkles sometimes occur during double side copying, caused by the formation of
moisture on the paper guides in the paper discharge unit. To remedy this problem,
ventilation holes have been added to the upper 2 paper guides and the lower paper
guides of the paper discharge unit, and the fixed supplementary paper guides have
been altered.
2.Cause: Moisture which forms on the paper guides is absorbed by the copy paper when being
discharged. When this damp paper is double side copied, it has a tendency to wrinkle.
In particular, when copying on damp paper, the moisture is vaporized and then forms on
the paper guides, causing wrinkles.

3.Description: Ventilation holes have been added to the upper 2 paper guides and the lower paper
guides of the paper discharge unit to prevent the formation of moisture.
Moreover, the shape of the fixed supplementary paper guides has been altered. These
measures are designed to prevent the wrinkling of the copy paper when both sides are
copied.
Changed lower paper guides of the paper discharge unit.

With this change the attachment position of the paper guide FA fixer unit has changed.
1) The F/R paper guide positioning plate is aligned with the top indicators of the Fu
frame F/R, and secured with screws. (originally center)
2) The paper guide FA is attached to the lower portion of the paper guide positioning
plate without clearance.
