paper wrinkles in konica minolta c452

[jemmanuil]

When i print through the bypass no paper wrinkle occurs, but when i print from the three paper trays (either a4 size or a3 size) a little bit of wrinkle appears on the sheets of paper. I tried interchanging the paper in the trays but the problem persists. Can you help?

Hi, how many copies has the machine done?

Possible wear on the exit drive gears?

these crusty old machines used to do that when page volumes got high and transport rollers diameters shrunk but it was always on A3. C451 series was worse for it. You can play with tray loop settings which helped me if i remember correctly. This is assuming no obvious damage such as snapped off fusing loop actuator.
