1. Ensure that the paper you are using is
• the correct type for the printer,
• correctly loaded in the printer, and
• loaded in the correct tray.
Perform Paper Tips Page procedure (Printer Menu > Troubleshooting > Paper Jams >
Paper Tips Page). The printer prints 3 Paper Tips pages. Follow the instructions on the
Paper Tips Page to perform the procedure.
2. Ensure that the paper loaded in the tray matches the paper type selected on the printer’s
