Re: sc 544-002 mpc4503

Thermopile heat detection error.

Take the fuser out and they are two sensors on a bracket above the fuser connector.
Check they are clean and aligned with the fuser.

Could be a problem with the new fuser if it's not heating up at all after the SC has been cleared. (check the sleeve lamps, thermostats with a multi-meter).

thank you sir for your respond

i checked and cleaned thermopile >>>>can you please tell me the best and easy way to measure the thermostat

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

thank you Imprestik

i did all this producer and all steps hat you said

i replaced the new fusing with new belt assemble and so 5810-002 but the device don't response and don't give complete but still waiting

Actually Ricoh recommend to replace the whole fuser for any SC 544 but you can just replace the damaged parts and reset with a fuse and SP 5810-02

SC544-02AFusing central NC sensor high temperature detection (hardware)In the event of an errorTriac defective (short-circuit)Engine controller defectiveHeating central thermopile defectiveFusing control software: out of control.

Attach the new fusing unit, then run SP-5-810-002 If the triac is defective, replace the AC power supply board If necessary, replace the BCU or the Fusing central NC sensor

Probably not stated correctly in my reply, but actually if you have tried all that you state and still have SC544/554 code there is a FIRMWARE update (D1495503) that address's this!

Re: sc 544-002 mpc4503

There should have been a fuse assembly taped to the inside of the box that a new fusing sleeve unit came in. That fuse has to be connected to the connector on the fusing in order for SP 5810 to work.

Re: sc 544-002 mpc4503

Had the same issue, fitted the fuse, updated firmware then I could reset the code in 5810-2

Re: sc 544-002 mpc4503

hi all

i made this steps:

1- upload nvram data from another device and down lode in the device who hade the sc

sc are gone but now the machine give me sc 995 -2

i put the sam serial number by sp 5801 in nvram and bcu
but it give sc 995-3???

Re: sc 544-002 mpc4503

Sorry I don't understand why you have felt the need to upload the NVRAM from another Metis to try and fix this problem.

You certainly didn't get that suggestion from anyone that's posted here.

You may of made this problem even worse for yourself.

Re: sc 544-002 mpc4503

The SC 995-3 tells me that either you loaded the NVRAM information a different model of METIS, either 3003, 3503, 5503 or 6003. The other possibility is that you entered the serial number incorrectly and the controller thinks the machine is not an MP C4503.

I hope that you made and saved a backup of the original NVRAM before trying to load the NVRAM from another machine. That way you can revert back to the original NVRAM. You the need to follow the instructions given previously in this thread. Otherwise, you are going to have to replace at least the NVRAM and possibly the controller board. If you do not have the birth certificate or a printout of the Non-Default settings, you might also have to replace the ID sensor assembly in order to have proper setup data for them.

what problems are you having that makes you think you need firmware.
