Fusing unit parts are very hot and may cause burn injury. Please wait after powering off the machine until it is cool to the touch before advancing.

  1. Remove the interface cover. (Interface Cover)
  2. Remove the fusing wire cover [A].
  3. Disconnect two connectors.
    *: Disconnect each connector of the paper exit PCB (PCB8) (a) and the fusing heater (b).
    Do not disconnect two connectors (c) of the fusing unit.
  4. Remove two screws (a)(M3x8: silver).
    (Screws that are secured at the position with the triangle engraving.)
  5. Detach the fusing unit (b).
  6. Attach the new fusing unit.
  7. Reattach the parts in the original position.

Take care not to touch the connector of the press-release sensor (S2) (b) when fitting the fusing unit (a).
A service call error may appear if the sensor is disconnected.

When attaching the fusing unit, first secure the screws and connect the connectors. (For prevention of damage from static-electricity)
Before reattaching the fusing wire cover, put the wire (a) in between the ribs (b) so that it is not caught by the fusing wire cover.
