7 Ways:

1. Clean the machine periodically as needed. Remove paper dust from the cassettes and the paper path as much as possible. This is also a good time to clean the platen glass and the scanning glass with window cleaner to remove possible debris.
2. Check that the paper guides in all the cassettes are set right and are clicked into correct position.
3. Reload any paper and make sure to fan it in order to get air in between the sheets. This will minimize the sheets sticking to each other.
4. Make sure to get good paper optimized for Copier/Printers. Inferior paper tends to have sticking and heat related problems.
5. Review how to clear jams in the Copier's Menu. There is a lot of information now available in the smart phone like interface. You can also take a look at the manual if it's an older machine.
6. Make sure that the Copier/Printer is plugged into a Surge Protector/Line Conditioner. These are usually provided by the dealer that installed it. These can prevent odd behavior and sporadic malfunctions.
7. Make sure that the machine is in a cool dry place and not near sources of heat or humidity. Heat and humidity are not good for proper function.
