While the fuser’s life is not dependant on media
size or type (one page of any size or type is
considered one page of life), media size, type,
and printing mode can affect the life
expectancy of the ITB.
For the ITB, letter-sized media or smaller is
considered to be the same size. Media sizes
larger than letter, such as legal-sized media,
decrease the life of the ITB due to the additional
rotations required.
