● Toner Ejection Sequence for Low Image Ratio
If printing is performed successively with a low image ratio, the developing performance may be degraded. To prevent this error,
an adequate amount of toner based on the average image ratio for each color (width = A4, length = a solid color band according
to the deteriorated toner amount) is transferred to the ITB.
Conditions for execution
When the average image ratio per sheet reaches 1% or less
Control timing
During last rotation after the job is completed, or 60 seconds after the copy job starts

● Drum Fusion Band Sequence
In order to prevent the toner, etc. from fusing onto the drum, a toner band of 10 mm is formed on the ITB depending on the
environment data (temperature/humidity) and usage conditions.
● Toner Band Control Sequence When Drum Stopped
If a new ITB is stopped for a long period of time while it is in contact with the Photosensitive Drum, it adversely affects the drum
surface and can cause white lines on the image.
In order to prevent this symptom and protect the surface of the drum, a toner band is formed when the ITB is stopped during a
period from the ITB's first use until 300,000 sheets are printed.
■ Warm-up Rotation Adjustment
Warm-up rotation is an operation to check the status of sensors, motors, and others, when the power is turned on, at recovery
from sleep mode, or at jam removal.
According to the conditions, warm-up rotation is performed.
Note that warm-up rotation adjustment is not performed when the state is "no Waste Toner Container", "waste toner full", or "no
toner".
