·Code: E078-0001
Description: Primary transfer disengagement mechanism failure
Causes: Primary transfer disengagement mechanism failure At the time of searching the home position: Considering that the coupling of primary transfer engagement/ disengagement drive may not be connected, the solenoid was pulled for maximum 6 times in the condition where the flag was detected once. But the hp sensor did not detect the color print engagement position. * If a flag is not detected even once, it is considered that the ITB unit is absent. At the time of changing the position The position after turning ON/OFF of the solenoid did not match the hp sensor value.
Remedy: Check whether the ITB unit is installed or not. Reconnect the connector J181 on the DC controller PCB. Check the primary transfer roller disengagement switch in the sensor monitor mode. If a failure is found, replace the primary transfer roller disengagement switch assembly. Execute the primary transfer roller engagement/disengagement drive test in the actuator drive mode. If the primary transfer roller does not perform engagement/disengagement, replace the fixing drive unit.
