Hi!
Welcome to The Canon Forums, and thank you for your inquiry!
We appreciate your participation, though we need to let you know that your product seems to be a model that is not supported by our team here at Canon USA. The imageCLASS MF4820D is a printer that is made for Canon India.
The Canon Forum is hosted and moderated within the United States by Canon USA. We are only able to provide support for Canon products manufactured for and used within the US market.
Feel free to discuss Canon products sold outside of the United States, but please be aware that you will not receive support directly from Canon USA.
Thanks for choosing Canon!
