When large numbers of copies are made within a short
time, the detection of the amount of used toner cannot
be made. As a countermeasure, the spring has been
changed.

For example:
* All day continuous copying
* 13K/1 day of copying continues for three weeks and

longer.

Notes

* In such cases, this change should be made.
* The current part has been supplied as a service part.
* DP-4580 has had this been applied from the first lot

at the factory.
