Ricoh MP C5503 SC544-02 code

I've not had to use a Reset fuse since they first came out 5-810 works fine for me but I do make sure the Firmware is updated on the machines I work on.

Thanks......appreciate the input. If firmware eliminates the need for that fuse to do a reset..............that would be great as sometimes customers don't need parts as it may have been a problem with the input power supplied or multiple machines on one circuit starving the machine for power and throwing a fuser code. Or just a dirty sensor/thermistor. I did update the firmware after the code was addressed.......

Closing out this thread-----The real skinny on this fix:
Firmware update will not be sufficient to reset error codes....Even after updating the firmware you must Use the reset fuse for the SC544 or 554 codes. You will absolutely need the fuse to reset those codes. Other fuser error codes may be reset using 5810-01 in service mode but once you have these codes you will need to replace the fixing belt assembly and install the reset fuse and reset it with 5810-02. (Or simply jury rig a reset connector with a push switch as described by other Ricoh techs in numerous posts)Hope that the effort to make this issue understandable helps others out in the future.

Well that's weird then I've had numerous SC codes related to the fusers usually caused by the users not clearing a jam and the sc resets work fine for me.

I have the correct fuse to reset the SC 544-02 but I am not sure where to connect it. Can any one explain where to connect the fuse to the machine? Thanks!

If you take the top and bottom covers off the fuser, look at the right hand side of where the lamps plug into. There's a little vertical slot the fuse fits in. It plugs into a two pin connector on the bottom of the black plastic frame.

Here's a pub I think I got here on CTN that always worked for me. I still carry an old Tmistor in my bag, even though I don't know when I last used it.
