CHAPTER 4 MAINTENANCE AND INSPECTION
4-1
1 Periodically Replaced Parts
The DADF does not have parts that need to be replaced on a periodical basis.
2 Durables
Some parts of the DADF may require replacement once or more over the period of prod-
uct warranty because of wear or damage. Replace them as needed by referring to the follow-
ing guide, in which the life of each part is expressed in terms of the number of originals
(may be checked in the copier’s service mode).
As of February 2001
*It is recommended that replacement be on a separation unit basis (FG6-7723). However, they (FG6-
7725, FE6-7724) may be replaced on their own.
