NOTE: The replacement timing indication of the periodical replacement parts can be
changed in the Next Life Set mode (Code 49). It is also changed as follows
whenever the total number of print pages is increased during normal usage.
• OPC belt cartridge: Life 60,000 images
If the coverage on a page is large, the load for the OPC belt cartridge gets high,
and its life is shorter than the actual number of images. Therefore, the
indication may be decreased depending on the coverage of each print page.
(For details, refer to the following page.)
• Fusing unit: Life 60,000 pages
For example, the lamp of the fusing unit is turned ON and OFF 10 times if one
page is printed per print job, and 10 pages are printed totally. On the other hand,
the lamp is turned ON and OFF once if 10 pages are printed per print job. The
load for the fusing unit is widely different even though the same number of
pages is printed, and the life of the fusing unit is also different. Therefore, the
indication may be decreased more than the number of print pages when few
pages are printed per print job. (For details, refer to the following page.)
• Transfer belt: Life 120,000 pages
It is not changed.
