Caution
When the drum drive assembly is
mounted, the gear of the drive assem-
bly and the flags of the developing
rotary assembly can interfere with
each other, breaking the flags. To
avoid this problem, be sure to move
the flags of the developing rotary
assembly so that they are out of view
inside the copier before mounting the
drum drive assembly.
