10-5-2 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 conditions of use. In
particular, depending on the degree of 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.
For replacement and checking of components, contact a
Sony service or marketing representative.
