Descriptions
2.2.9 PCU DETECTION
The PCU set switch [A] is installed on the main unit (under the bottom center of the
PCU). It detects the presence of a PCU. The used toner tank case presses the
PCU set switch. Therefore, when the used toner tank is absent, the PCU detects
that it is missing.
2.2.10 CHARGE CORONA UNIT DETECTION
The main unit has a switch [A] to detect the presence of a charge corona unit. If the
charge corona unit [B] is installed in the PCU, the charge corona unit activates this
switch. The switch actually detects the sliding cleaner for the grid and charge
corona wire. If the user has not put the sliding cleaner back in its home position,
the LCD will display an error message.
