The machine is equipped with a fixing inlet sensor to prevent paper from remaining inside the fixing assembly. The output of the sensor is used to move a lift mechanism,
thereby making sure paper movement will not be disrupted.
ERROR CODE:
E840 (fixing inlet sensor movement error)
Indicates that a fault occurred while the wrap sensor is being moved up/down, thus causing HP detection to fail.

0000 = The home position is not detected when he sensor is moved up/down (i.e., the
sensor has not gone on).
0001 = The home position is not detected when the sensor is moved up/down (i.e., the
sensor has not gone off).



*Disconnect and then connect J508, J552, and J553 of the DC controller PCB.
*Disconnect and then connect J4001 and J4002 of the fixing inlet sensor ascent/descent motor driver
PCB; as necessary, replace the fixing inlet sensor ascent/ descent motor.
*Replace the fixing inlet sensor ascent/descent motor driver PCB.



If HP detection fails when the fixing inlet sensor is moved,
the machine will indicate error code E840.
