ALL-IN-ONE CARTRIDGE (AIO CARTRIDGE)17 May, 1999
The following table shows how the two SP modes can be used to customize the
toner near-end and end intervals.

Notes on how to customize the settings
? A higher 'Total' means that the user can use the cartridge for longer. However,
copy quality may deteriorate before the toner end warning occurs.
? With a smaller number of copies between starting the counter and near-end, the
user has an earlier warning that the toner is running out.
When the toner near-end sensor has detected a high toner condition for five
continuous seconds, the machine does not check for toner end/near-end condition
just after the main switch is turned on, or after the right door is opened and closed.
The near-end copy count continues.
If the sensor detects a high toner condition for more than 30 seconds, the machine
stops the near-end copy count. The counter is then reset and the near-end or end
condition is changed.
Toner Supply
The AIO cartridge agitators and mixing blade mix the toner in the AIO cartridge.
The toner near-end sensor is not used to control toner supply. When the machine
is turned on or the right door is closed, the agitators and the mixing blade rotate to
mix the toner for a brief period.
Development Bias
The high voltage supply unit gives the development roller a charge of -400 V DC
and an AC component of 1.6 kVp-p 1 kHz. To prevent toner from transferring to
non-image areas on the drum, the development bias is different for image and non-
image areas.
