Please check the following points:
1: Choose Thin Paper mode in the printer driver and re-send the print job.
- Open the back cover.

Position B is only for 2-sided(duplex) printing with recycled paper when the temperature and humidity are low.
- Close the back cover.
- Choose Plain Paper mode in the printer driver and re-send the print job.

When you have finished printing, open the back cover and reset the two grey levers back to the original position.
