1st transfer roller pressure/retraction control

• To extend the service life of the photo conductor/Y, M, C, the pressure position of the 1st
transfer roller is changed between the monochrome mode and the color mode.
The 1st transfer roller/K is not provided with a retraction mechanism; the transfer belt is
pressed against the photo conductor/K at all times.
• The Transport motor provides the drive for pressure/retraction operation of the 1st trans-
fer roller/Y, M, C.
A. 1st transfer roller pressure operation
