Sharp AR163 CODE ERROR F2 04 solution - Sharp Office Equipment & Supplies

SOURCE: SHARP AR163 Displaying H2 error

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.
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.
