Transfer Belt is a rotating belt that carries the image which is a mixture of different colors of toner particles to the paper surface before the paper reach into the fuser unit.
The belt unit (BU300CL) in your Brother machine has a life expectancy of approximately 50,000 pages when printing on letter size media. Its actual life expectancy will vary with the type of media used in the machine, number of pages in a print job, etc.
Please note that the belt unit must be replaced when the machine displays 'Change Parts Belt Unit'.

Failure to replace the belt unit may result in print quality issues or paper jams.

After the belt unit is replaced, the belt counter must be reset to zero otherwise the machine will NOT automatically reset the belt life counter.
