• The fusing sleeve belt unit is designed with a highly soft material. Do not touch the fusing sleeve belt unit with your hands to prevent dents during replacement. If you have touched it and a dent has been made, the dent will gradually become larger during operation and it can cause a fusing malfunction or sleeve belt breakage.

  • To cancel SC544-02/SC554-02, it is necessary to replace the fusing unit or install an intact new unit detection fuse included with the fusing sleeve belt unit.

  • If you are replacing the fusing sleeve belt unit for PM or any reason other than canceling SC544-02/SC554-02, you can discard the fuse that is packed with the new fusing sleeve belt unit.
