Here are some steps to troubleshoot your printer:

1. Check that the settings on your computer or device match the print settings of the printer.
2. Check that the cables connected to the printer are secure, and not loose or disconnected.
3. Check the toner level by printing a test page. If the toner is low, reload the print cartridge.
4. Ensure that you are using the right paper. Different types of paper print better with specific settings.
5. Clean the print heads if the colors are not lining up correctly.
