Sharp Fuser
H2-0 Fusing unit temperature error
H4-0 The fusing unit doesn't heat up.
***ALWAYS DISCONNECT POWER WHEN WORKING ON MACHINE***
You have to reset fuser errors with simulation 14. Push P * C * then 14 then Start (the button you use to make copies) and it should reset the code. If not then replace the fuser.
SM 5-1 should turn the lamp on. If lamp blinks on and off it is the thermistor, if it does not it is the lamp, but check the contacts on the lamp/fuser -- they have been known to erode.
Also check thermal fuse, if defective replace.

on this code you may have to clean out the developing unit and start with fresh developer. Make sure the developer unit is not leaking from one of the bearings. You may need a tech for this one...
