Make sure that the paper in the paper tray is straight. If the paper is curled, straighten it.
Reduce the amount of paper in the paper tray.
Check if the LCD or LED shows some error. If necessary, refer to “FAQs & Troubleshooting” for information on the error message or the LED light.
Check the Paper Source setting of the printer driver. If “Manual” is selected for “First Page”, change it to “Auto Select” or “Tray1”.
