    Look in the Index portion of the parts guide - look for NFAN..., it will show all sections and item #s of the fans.
    Section 37 has your two fans in the delivery unit, not sure of the two below black toner.

        Hard to tell from the parts guide but it looks like section 48 part # 101 LSU Radiate fan is the part that you are looking for. Don't know why they are calling it that since it is shown on the frame under the toners.

        Good luck.

          Sorry, the updated parts guide doesn't have an Index section.

              We encountered that error code in MX-3500 the 2 fan is located at the top of the black drum/dv unit. Just remove the transfer unit, it is very easy to find, you need only thumb screw to remove both of them.

              Good luck...

                  Replaced one last week for same code, but MIGHT be the toner fan above primary tx belt unit.

                    I carry those 2 fans (above the delivery unit) they burn out quite often from the heat of the fuser. They were the main reason many of our techs have been replacing the unit for, what a waste of money that is!!
