Important Information about Replacing the Fusing Thermistor 
 
! The AW100149 fusing thermistor is marked with a pink dot. When you replace the 
thermistor, make sure that this pink dot faces the bracket, as shown in the photos 
below. (The dot is visible through the bracket after you attach it). 
 
!  Currently, this thermistor cannot be supplied. If you need to replace the fusing 
thermistor, use the AW100147 thermistor instead. It is the same thermistor. 
IMPORTANT: The AW100147 thermistor is not marked with a pink dot, so make sure 
that the side of thermistor that covers the harnesses (shown in the 
right side of the photo) faces the bracket.
