1. Open the upper inner cover, and then cover the PCDUs with a sheet of paper, to prevent foreign objects from falling into the PCDUs. (PCDU)
  2. Remove the snaps and flat cable from the LED head [A] (×2,×1).
  3. Lift the toner end sensor unit [A] upward, and then slide it in the direction of the arrow.
  4. Remove the connector from the toner end sensor [A] (×1).
  5. Release the harness from the guide hooks on the cover (hook x5 for BK, x3 for CMY).
  6. Raise the hook [A], and then slide the discharge lamp cover [B] in the direction of the arrow to remove it (hook x1).

  7.  Only when removing the LED head (BK), remove the cables (purple×2, orange×4) one by one in advance from the harness guide [A] at the rear right corner.

    This is necessary to make allowance for the harness when removing the connector in the next step. Unlike other cable guides, this part has mylar [B] attached to prevent the cables from coming off, so it is more difficult to remove the cables here. Be careful not to break the cables.


     

  8. Disconnect the connector for the discharge lamp and remove the LED head [A] (×1).


 

  • The flat cables of the LED heads have different colors. They have a fixed order.
  • If you remove the flat cables of the LED heads, during re-assembly connect them so that they overlap in the order of Y / M / C / K.

[A]: Flat cable: EGB: LED head Y

[B]: Flat cable: EGB: LED head M

[C]: Flat cable: EGB: LED head C

[D]: Flat cable: EGB: LED head K
