7-4. Detection of Toner Cartridge
(1) Installation detection
• The IC chip (CSIC) built into the Toner Cartridge detects that the Imaging Cartridge is
installed in position when the power switch is turned OFF and ON, and the Front Door is
opened and closed. The detection is made electrically.
(2) Detection of a new Toner Cartridge
• The IC chip (CSIC) built into the Toner Cartridge detects a new Toner Cartridge only
when it is first installed.
(3) Toner near empty and empty detection
• The built-in CSIC Board counts the amount of toner still available for use in the Toner
Cartridge.
• The counter counts one when the amount of toner equivalent to A4, B/W 5 % is con-
sumed and the corresponding data is stored in the CSIC Board.
• A toner near empty condition and a toner empty condition are detected when the counter
reads the corresponding predetermined count.
