3.4.4 Switch between Color Print Mode and Monochrome Print Mode
By switching the mode between color print and monochrome print to avoid unnecessary load
on the toner cartridges and keep the specified product life, the rotation and press/release
operations of the develop roller are controlled, and the print operation is executed.
<Rotation of the develop roller>
The gear is driven by the develop drive motor through the clockwise or counterclockwise
rotation, and all four develop rollers for four colors (K, Y, M, C) rotate in the color print mode,
and the one develop roller for the black color (K) only rotates in the monochrome print mode.
<Press/release operations of the develop roller>
By rotation of the develop release motor, all four develop rollers for four colors (K, Y, M, C)
press corresponding exposure drums respectively in the color print mode, and the one
develop roller for the black color (K) only presses the corresponding exposure drum and the
remaining three develop rollers for three colors (Y, M, C) are kept separated from the
exposure drums in the monochrome print mode.
