unplugged from the wall outlet.
Caution1: Be careful not to touch the drum or
the cleaning blade with bare hands,
or damage them.
Caution2: When leaving the drum, be sure to
put the drum cover over the drum
and store it in a dark place.
Caution3: When reinstalling the drum, cleaning
blade, and toner guide roller, apply
setting powder to the entire surface
of the drum and also to the cleaning

parts are new or old.
Caution4: After applying setting powder to the
drum, perform the following before
installing the drum unit in the main
body.
1) With the charging corona unit and

vent image defects).
2) When installing a new drum, be
sure to enter mode 25 and select
"Copy Count by Parts to be
Replaced" to reset drum counter.
(See "ADJUSTMENT.")
