Replacement reference: For replacement, refer to each paper feed counter value.

: 200K or 1 year

: 100K or 1 year
SPF section
: 100K or 1 year
Torque limiter
: 800K (However, 400K for manual  paper feed section)
(NOTE) Paper feed section roller life
Since each roller life is 100K or 200K, if a certain paper feed unit is inten-
sively used, its life may be expired before the regular maintenance timing.
In actual, however, different sizes of paper are used with different paper feed
trays. Therefore, it is quite rare to have to replace one of the rollers before the
maintenance timing.
When a certain size of paper is used intensively, it is advisable to set two or
more paper feed trays for that paper size as far as possible. This note should
be explained to the user.
When servicing, be sure to check the use frequency of each paper feed tray,
and replace a roller if necessary.
When cleaning rollers, it is advisable to use wet waste cloth to wipe and
clean.
Since the paper feed trays 3 and 4 are used for larger sizes of paper than the
paper feed trays 1 and 2, the life times of their rollers are shorter than those
of the paper feed rollers 1 and 2.
The degree of wear of the paper pickup roller is greater than that of the paper
feed roller, which greater than that of the separation roller.
(Paper pickup roller > paper feed roller > separation roller)
