Toner cartridge (TC) life control
A. Toner cartridge detection and new cartridge detection timing
• The machine attempts to perform a detection sequence when the front door is closed.
B. Toner Cartridge detection
• The machine accesses the TC detection board (CSIC) to check for data stored in it.
Using that data, the machine determines whether or not a toner cartridge is loaded.
C. New toner cartridge detection
• After a toner cartridge has been detected, the machine determines whether it is new or
not based on the data acquired.
D. Toner cartridge near empty and empty condition detection
• The amount of toner consumed is calculated from the number of dots produced for one
printed page by the controller. A toner near empty condition and a toner empty condition
are thereby detected.
<Toner near empty decision>
• The machine determines that there is a toner near empty condition when the image
counter and dot counter reach the life value.
<Toner empty decision>
• The machine determines that there is a toner empty condition when a predetermined
number of printed pages are produced after the toner near empty condition has been
detected.
