Method of counting the number of toner replacements

This machine keeps the number of times that the toner cartridges are replaced and the page
counters to learn the usage of the machine. These counters will not be deleted even if the
power is turned OFF. The following tables explain the method of counting the counter values
when the toner cartridges are replaced.
<When a brand-new toner cartridge (unused) is inserted after "Replace Toner" is
displayed>

Developing bias voltage
*1
Excluding a toner cartridge in use in which there is a little toner remained.
*2
The developing bias voltage is reset to the initial setting once when a toner cartridge which
is not brand-new is inserted. After resetting, the developing bias voltage correction is
performed so that the developing bias voltage is corrected according to the amount of
toner.
Note:
While the parameters explained above are separately controlled for 4 color toners, the
same counting method is applied.
