Print on both sides of paper (Auto 2-sided/Duplex Printing for Mac OS X 10.5.x or later users).
Before printing, make sure that you set the duplex paper adjustment lever at the back of the printer to LTR/LGL or A4. When using Folio size paper, set the lever to LTR/LGL.
If you try to print when the paper adjustment lover for 2-sided (Duplex) printing is not correctly set for the paper size being used, the LCD will show DX Lever Error and the machine will stop printing. If this happens, move the lever to the correct paper size position.
Please follow the steps below to print using Auto 2-sided (Duplex) setting.
Choose Print from the File menu and open the Print dialog.
Choose Layout.
Choose Long-edge binding or Short-edge binding in the Two-Sided.
