WorkCentre 7855 prompt “Supplies Plan Expiring Soon”

Thank you very much for your reply, but when I chose technical support and didn't have any contact details in my area, I felt desperate and no one could help me just because I bought a used device.

I bought a second-hand 7855. After the power failure, it prompted that "tSupplies Plan Expiring Soon". How can I fix this problem?
There is no technical support in my area. My mother tongue is not English. The above are input through translation software. I hope I can get help.
