B. Pressure position changing mechanism
• To extend the service life of the PC drum/Y, M, C, the pressure position of the 1st image
transfer roller is changed between the monochrome mode and the color mode.
• The 1st image transfer roller/Y, M, C presses the transfer belt only in the color mode.
• The 1st image transfer roller/K presses the transfer belt in both the monochrome and
color mode.
Color mode:
• In the color mode, the 1st image transfer roller/Y, M, C is pressed against the transfer belt
and PC drum and the PC drum/Y, M, C is rotated.
Monochrome mode:
• In the monochrome mode, the 1st image transfer roller/Y, M, C is retracted, so that the
PC drum/Y, M, C remains stationary.
