OPERATING PRINCIPLES Control 112
Control of Toner Cartridge
1. Detection of Empty status
The judgement of the Empty status of Toner Cartridges is made based on toner
patch density values (read by ADC sen sor). When toner patch density is extr emely
low, the printer executes forced supply of toner (Admix operation), and it judges
that the cartridge is empty if the density of toner patches created after the forced
supply is still low.
2. Reset of the Empty status
The printer judges that the empty Toner Cartridge is replaced with a new one when
the power is turned off and back on, and the cover is opened and then closed
during the Empty status. Then the printer executes forced supply of toner from the
newly attached cartridge.
