The marks caused by friction/Wrinkles on the second side of the
paper of duplex printing due to using thin paper
[Symptom]
In case of duplex printing using thin paper, the marks caused by friction of image [a] / [b] on the front /rear side edge of the second
side of paper or Wrinkles [c] on the center of paper may appear.
The arrow [d] indicates the direction of feeding.
[Cause]
Depending on the type of paper, Curl may be bigger even the temperature of fixing is the same.
If the paper has big Curl after fixing of the first side of the paper, the curl [b] touches the Tray Duct (Lower) [a] before the second
side of paper is entering fixing Nip, and then it makes transferred toner image scrambled. Consequently the marks caused by
friction appear.
If the paper having curled edge enters the fixing Nip, it causes Wrinkles on the page.
