Thanks for letting us know what Canon product you've got. The PIXMA MX300 is an older model which we have retired. While that means that Canon USA no longer offers direct support for it, your friends here in the Canon Community are welcome to offer suggestions!
You can also speak with a Canon Upgrade Program specialist to help you score a modern replacement that would meet your current needs at a discount. You can reach them weekdays and Saturdays at 1-866-443-8002.
Hope this helps!
