determined based on the counter value (See Section 2.16).

the count of 2000 is reached after belt waste toner near full is
detected.

2.14 Version Read of Units Replaced Periodically
The version of each of the I/D, fuser unit and belt unit which are replaced periodically is determined
whether it is new or previous according to whether the fuse in it is conducting or out of conduction.
When the fuse is conducting, the unit is decided that it is new. The “new” or “previous” judgment
is performed at power-on and at cover-close. The life counter of every new unit is re-set and the
“new” or “previous” judging purpose fuse in the unit is cut.
2.15 Life Count for Units Replaced Periodically
The life of each of the I/D, fuser unit and belt unit which are replaced periodically is counted as
shown in the following table:
2.16 Toner Consumption Detection
The used toner amount is detected by counting the number of dots printed. After toner low is
detected, when the equivalent of 800 pages on A4 and 5% duty is reached, toner-empty occurs.
After turning the power on again, or opening and closing the cover, 20 pages can be printed.
