Maintenance Timings
Use the following table as a timing guide for checking
and replacing components of the unit.
These intervals are not guaranteed lifetimes; the timing
for replacing components depends on the particular
conditions of use. In particular, depending on the
degree of dirt contamination and abrasion, pinch
rollers and cleaners may require replacement earlier
than suggested by this table.
Note that an arrow in the table means that the
component to be replaced is part of the assembly the
arrow points to, which must be replaced as a whole.
For information on severe conditions (frequent threading/
unthreading) or how to replace components, refer to the
Maintenance Manual Volume 1.
Note
Contact a Sony service or marketing representative
regarding the replacement and checking of
components.
