- Adjust the paper guide to match the recording paper size.
- Try reversing the recording paper in the paper tray, or rotating direction of the paper
for 180 degrees.
- Check thickness of recording paper is within tolerance of each type.
- Check that the number of recording paper loaded in the paper tray is within specified
volume.
- Clean the paper pull-in roller.
Step Cause Solution
