CRU (ALSO KNOWN AS AIO) 6.3.1 NEW CRU (AIO) DETECTION A new supply CRU cartridge has a fuse [A]. The machine knows that a new cartridge has been installed when the fuse is detected. The starter CRU does not have fuse. When the new cartridge is installed, the machine will automatically detect the fuse. The fuse will blow. This opens the circuit when you install the CRU. The machine will then reset the total dot counter (TOTAL TONER COUNT), CRU print counter (Cru Prints), and increments the counter for counting the number of CRU replaced (Replaced Toner Counts). [A] B173D999.tif 6.3.2 TONER END DETECTION The machine does not have a toner end sensor. The machine determines the amount of toner with software. The machine counts and adds the number of black dots used as the toner consumption. For example, when the machine prints 5% of black rate chart, approx. 1,165,000 dots will be used (added to the total count). When the total number of dots reaches a pre-programmed count (toner near-end), the machine will display "TONER LOW". After another period of dots being counted, the machine will display "TONER EMPTY" (toner end), and the machine will stop printing. You can check the total dot count from the current AIO in the System Data List in TECH mode. B173 6-6 SM

6.3.1 NEW CRU (AIO) DETECTION
A new supply CRU cartridge has a fuse [A]. The machine knows that a new
cartridge has been installed when the fuse is detected. The starter CRU does not
have fuse. When the new cartridge is installed, the machine will automatically
detect the fuse. The fuse will blow. This opens the circuit when you install the CRU.
The machine will then reset the total dot counter (TOTAL TONER COUNT), CRU
print counter (Cru Prints), and increments the counter for counting the number of
CRU replaced (Replaced Toner Counts).
6.3.2 TONER END DETECTION
The machine does not have a toner end sensor. The machine determines the
amount of toner with software. The machine counts and adds the number of black
dots used as the toner consumption. For example, when the machine prints 5% of
black rate chart, approx. 1,165,000 dots will be used (added to the total count).
When the total number of dots reaches a pre-programmed count (toner near-end),
the machine will display ±TONER LOW². After another period of dots being
counted, the machine will display ±TONER EMPTY² (toner end), and the machine
will stop printing.
You can check the total dot count from the current AIO in the System Data List in
TECH mode.
