Wow this thread escalated quickly LOL.....

I should have updated it years ago but what I eventually found out is you don't even need to use SP5810-002 when you have this code.

Before switching off the device, go to SP3701 (i think it is) and set the fusing unit, belt and pressure roller to 1 to tell the device you are replacing it with a new fuser.

Switch it off and back on and off you go, the device will do process control, reset all fusing codes and fusing PM counters and work like a charm.

In saying this the fuser was also replaced

Never had a problem since

ok wait Imprestik .. you say you replaced the fuser so that wouldve had the new fuse thus reset the SC554 code.. i suppose along with sp3700 counter reset.
Im wondering if a MPC4503 with a SC554-02 code will reset just by reseting counters in sp3700.. or is it 3902?

I have one with stripped drive gears, and sc554-02 code.. but i dont have the fuse...

Have a great day all you copier warriors!

No it will not reset without a fuse

A new fusing unit from Ricoh will have the fuse already installed. A replacement fusing sleeve from Ricoh will have a fuse taped inside to the bottom of the box. If you are buying parts from after market suppliers and they do not have a fuse, too bad, so sad, you get what you pay for.

You can not reset this spanner code without installing the new fuse that comes with the new belt assembly.

Rebuild your fuser and replace the fuse at the same time, install it and the spanner code will still appear. Reset the fusing code now using SP5-810-002 and it will say completed, reboot device and it will come back to life

Welcome back.I have a similar problem with the MP C3003 model.The furnace is at 27% consumption, code SC 544-02 occurred.replaced new furnace with a new fuse SP 5-810-01 resets with the result "complete", while SP 5-810-02 pops up the message "error".previous furnace in another machine works fine.I uploaded a new firmware package, replaced both power supply boards and it's still the same.Does anyone else have an idea what could be broken?
