This photoconductor exhibits greatest light fatigue after being exposed to
light over an extended period of time. It must therefore be protected from
light by a clean, soft cloth whenever the PC Unit has been removed from the
copier. Further, use utmost care when handling the PC Drum to prevent it
from being contaminated.
