6.3.3 Checking the toner cartridge count
Information about the 'toner cartridge count' can be checked by printing the Configuration Sheet.
6.3.3.1 Remaining Toner : xx%
- Contents : Shows the remaining amount of toner.
- Description : It starts with 100%, and it reduces every 5% unit until it becomes 0%. (A message "Low
Toner" is displayed in a LCD when it reaches 10%.)
* In a low toner status, additional 800 sheets can be printed (5% coverage pattern standard-8K car-
tridge)
6.3.3.2 OPC Count : XXXXXX
- Contents : It starts with 0 and increases to display count.
- Description : It is an imaginary page count that accumulates a rotating time of a Main Motor. When the
count reaches 20,000(pages), a message "Replace cart" is displayed in LCD. It means
the life span of the toner cartridge (except a toner part) has ended. Even though it is a
case that a toner is refilled, the rest of major parts should end, so entire toner cartridge
should be replaced. In the worst case, when an OPC rotates over 20,000 pages, it is pos-
sible that a toner may overflow. When the count reaches to 20,000 pages, the printed
image becomes misty, and an On-Line key that is flashing on a set must be pressed for a
single print. If an OPC count is under 8,000 when displaying a message "Remaining Toner
:0%", it means that a high-coverage has been used. If an OPC count is over 8,000 and if
it has not been reached to 0% yet, a low-coverage should was used.
6.3.3.3 Manufacture Date : 2003.01
- Contents : Shows the product year and the month of the developer.
6.3.3.4 Supplier
- Contents : shows the brand name of the developer.
- Description : If a supplier is other OEM, the other OEM's name is displayed. If a supplier is different
between a set and developer, a message "invalid toner" will be displayed in a LCD of a
set, and a machine turns to an impossible status to print.
