(3) Operation
(a) Photoconductor drive mechanism
• Two independent photoconductor motors (for color and black) are used for the drive mechanism to suppress incorrect color registration
and uneven pitch.
Photoconductor/K drive mechanism
• The main motor drives the photoconductor/K.
• The main motor is the common source that provides drive to manual bypass feed, tray feed, registration roller, transfer belt, and
others.
• Drive is transmitted to the photoconductor when the triangular-prism-shaped shaft is engaged with the mating coupling part.
