5.6.1 Detecting the Installation of Transfer Roller
Whether the Transfer Roller is installed is detected when the power is turned on, or the front cover is
opened and closed. The sensor for detecting the installation is not provided, but judgment is made from
the output of the AUTOMATIC DENSITY CONTROL SENSOR.
The light is emitted from the LED of AUTOMATIC DENSITY CONTROL SENSOR with the specified
light quantity, and if the output of the AUTOMATIC DENSITY CONTROL SENSOR is larger than the
specified value, the controller judges as installation. If the operation stops by a jam, the toner image
could be put on the BTR and in such a case, the sensor output is reduced, causing the controller to
judge as uninstallation. To prevent this wrong detection, the BTR is rotated by a half turn if the output is
less than the specified value. Then, when the output of the AUTOMATIC DENSITY CONTROL
SENSOR is larger than the specified value, the controller judges as installation, or if less than the
specified value, the controller judges as uninstallation.
5.6.2 Detecting the Life of Transfer Roller
The Transfer Roller consists of a BTR and a waste toner recovery system. The life of the Transfer
Roller is detected when the toner recovery space has become full.
The full toner recovery space is detected by the SENSOR TONER FULL.
1) Check timing of full waste toner recovery space
- When the power is turned on, or the front cover is opened and closed
- When paper is outputted
2) Output of "BTR Life Warning"
The "BTR Life Warning" is outputted when the SENSOR TONER FULL detects the full toner
recovery space.
3) Output of "BTR Life Error"
After the output of "BTR Life Warning", the print count and the toner dispense time are counted up,
and if total counts exceed the specified value, the "BTR Life Error" is outputted.
4) Reset of "BTR Life Warning"/"BTR Life Error"
The "BTR Life Warning" and "BTR Life Error" are reset, if the SENSOR TONER FULL does not
detect the full toner recovery space when the power is turned on, or the front cover is opened and
closed.
