[ 2 ] Functions of the toner cartridge PC board (CTRG)
An IC chip is embedded in this board. Data such as identification information for the recommended
TOSHIBA toner cartridge, thresholds to determine if the cartridge is nearly empty, and controlling data
for the image quality to be optimal according to the toner characteristics are written in this chip.
To measure the amount of toner remaining in the cartridge, when the value of counter for period of
toner cartridge rotation time (08-6246) is updated, this equipment writes the updated value into the
toner cartridge PC board (CTRG).
These data written in the toner cartridge PC board (CTRG) enable the functions below, and accordingly
this equipment operates as shown below. Data reading is performed every time the power of this
equipment is turned ON and the toner supply cover is closed.
