I have a Samsung express c460fw printer .. I have installed a new belt and my printer says prepare new belt and replace fuser soon.

I saw on another thread there was a tech mode sequence .. is this correct for this unit ??

I called Samsung they said its not reading to because its not a factory part .. So i called the manufacturer and they said IT IS an OEM / Genuine part.

I went thru the reset sequence but was unable to find or access tech mode ??

Please advise

Thank you
