Subject: Paper Creasing in Duplex Mode Prepared by: N. Kaiya
From: QAC 1st Field Information Dept. Checked by: T. Inoue
Classification:
This RTB explains the countermeasure for paper creasing in duplex mode. The problem
was found during our product test and so far it has not been reported from the field.

PROBLEM
Paper creasing on the back side of duplex copies. The problem is likely to occur under
the following conditions.
• High humidity
• A3, DLT or A4 lengthwise, LT lengthwise
• When the face side has a large solid area with blank margins around it.
CAUSE
When copying the back side in duplex mode, the paper feeding speed over the pressure
roller differs for solid image areas and blank areas. The difference of friction with the
pressure roller may cause this symptom. (Friction : Image area > Blank area).
Therefore, if the face side copy has a large solid image with blank margins at both sides,
the sides of the paper will feed slower than the middle part, causing the paper to crease in
the middle of the trailing half.
COUNTERMEASURE
1. We have tested various combinations of nip band width and configurations of the hot
roller and the pressure roller (concave). As a result, the following condition was found
to be the optimum to counteract this problem.
Old New
Nip Band Width
Hot Roller No Change
6.5 ±0.5 mm 5.0 mm ∼ 5.5 mm
(front to rear deviation within 0.5 mm)
Pressure Roller Concave
+0.01 ±0.01 mm +0.05 ±0.01 mm
RICOH Technical Bulletin PAGE: 2/6
Model: Azalea Date: 15-Mar-97
2. Due to the change in nip band width, the following two changes are made.
• The fusing lamp has been changed. The new lamp heats the front half more
strongly, since fusing ability became inferior in this part.
• The fusing and paper exit unit (P/N A1664350) has been changed because the
change in nip band width slightly raised the paper path, and an OHP transparency
might hit the tip of the paper exit guide. The part number of the fusing and paper exit
unit is not changed since only a few old parts have been shipped.
3. In addition, countermeasures are added for the following two side effects which were
found during our test.
Blurred image
This problem may appear when non-recommended paper copy is used for duplex full
color copying. The blurred image is likely to occur when the difference of nip band
width between the center and the sides becomes large. Because this difference of nip
band width affects the slackness of the paper as it enters the nip band, if the paper is
too slack, the paper touches the hot roller before entering the nip band. Therefore, the
image will be rubbed, causing the blurred image.
The paper entrance guide has been modified to lower the paper path, preventing the
paper from touching the hot roller surface before entering the nip band.
No: 3
Scratched Image
If the paper becomes too slack before entering the fusing unit, the paper will come into
contact with the upper fusing entrance guide, causing a scratched image.
Four spurs are added on the oil sump to prevent the paper from touching the upper
fusing entrance guide.
