• Code: CD4
• Description: Full toner bag
• Remedy: (1) Check the toner bag. • Is the toner bag full? (2) Check the toner full detection sensor. • Is the tone full detection sensor working properly? • Is the connector not disconnected? (3) Check the used toner transport motor. • Is the used toner transport motor driving? • Does the pulley beside the motor become heavy when it is turned toward the direction of arrow (counterclockwise)? (4) Replace the LGC board. (5) Release the status counter. • Turn the power ON while pressing both the [0] and [8] keys. • Press the [START] key after inputting [399] with digital keys. • Change the status counter "1", "2" or "3" to "0" and press the [SET] or [INTERRUPT] key ([CD4] released). • Check if the copier becomes to a standby state normally when power is turned ON again. • In case that the used toner transport motor does not drive or [CD4] is not released when power is turned ON again, do the above procedure after manually turning the pulley beside the motor toward the direction of arrow (counterclockwise) several times.

• Code: CD5
