Operation
4.2.1
Toner Level Detection (magicolor 5430 DL/5440 DL)
• The toner level is determined by the accumulated time of rotation of the toner supply
motor and the PC Drum.
• The toner levels of the magicolor 5430 DL/5440 DL can be checked through the “MENU/
SPECIAL PAGES/PRINT CONFIG PAGE” or “MENU/CONSUMABLE USAGE” configu-
ration menu.
NOTE
• When the toner remaining in the cartridge is between 88% and 100%, the display
shows “100%,” regardless of the actual amount. The amount of toner supplied to
the toner cartridge may vary slightly. Also, some toner is consumed when check-
ing the screen during manufacture.
• When the amount of toner is 87% or less, the display shows the exact amount of
toner.

• The toner level is determined by the accumulated time of rotation of the toner supply
motor and the PC Drum.
• The toner levels of the magicolor 5450 can be checked through the “PRINT MENU/STA-
TISTICS PAGE” configuration menu.

4.2.3
Toner near-empty condition detection
• The cumulative period of time through which the Toner Supply Motor is energized is
detected as the basis for determining whether there is a toner near-empty condition.
• When a new Toner Cartridge is detected, the cumulative energization time counter is
reset to let it start counting the time anew.
•
1.
The machine determines whether there is a toner near-empty condition when the
cumulative energization time counter of the Toner Supply Motor exceeds a predeter-
mined value.
•
1.
A toner near-empty condition is reset when a new Toner Cartridge is detected.
• About 500 to 1500 printed pages can be produced during the period of time that begins
when a near-empty condition is detected and ends when an empty condition is detected
(for a standard original of a 5% coverage rate and using a standard Toner Cartridge).
• A warning message is displayed when a near-empty condition is detected.
