Re: MPC-3502 sc554-00(holy sh..!)

Take the fuser cover off and it is on the side as the thermofuses. If the fuser is the original then there will not be an existing fuse. If it has already been replaced then there will be something in the connector. We have been hanging the connector outside the cover for easy fuse swapping. We have 7 machines that are 1 hour 15 minute flight from here with poor power.

Thanks for the info

thanks for that, looks like a printer unit fuse

That is the same fuse that I have. Where do I plug this in. I am assuming on fuser somewhere. I have no idea if the fuser is an older or newer one. I have to drive 1 hour to get to customer.

I can confirm the push switch mod works fine.

1. Fit the fuser, closed the side door and power on.
2. Enter SP mode and goto SP5810-002.
3. Before you tap execute push and hold the switch in.
4. Tap execute, now instead of a instant failed message there will an slight pause, this is when you let the push switch out to simulate the fuse blow.

The PM counter for the fusing unit automatically resets when an new fusing unit is detected.


Additional notes

The machine does not appear to check the new fuser circuit until you tap on execute (SP 5810-002).

The 2 pin connector is present but empty on the original fuser that comes with the machine.

I'm still not sure at this time if the machine is actually waiting / checking for the break in the circuit before successfully executing.
Even if it does not require the break in the circuit to work I'm not sure if damage would not occur with a permanently connected loop.

Blaze something. would the fuses attached to previous model printer kit units do the job

If you are fitting the ricoh part fuse to a refurbished or repaired fuser, the machine will think the fuser is a brand new one. Insert fuser, 5810, done.

I would emulate the fuse with the push switch thus: close switch, insert fuser. 5810, open switch, done. From the reading I have done, you will not be able to execute 5810 until the machine thinks a new fuser is there (closed switch).

Blase a trail zames!

I've got my push switch ready to go, just waiting for the chance to use it. Is there a set time to release the switch or is it just a case of executing the SP and then release the switch?

From what I have read on the TSC forum from someone is that the original fuser does not have the fuse installed. When you order a new fuser it does. To reset the error, take an old thermistor (aw10 0052) I believe and cut the sensor end off. Plug it into the connector in the fuser cavity and hang out of the machine. Install the fuser and short the wires together. Go into sp 5810-2 and hit execute and open the wires and voila... This was posted on the 5502 but should be the same. I have not had to test it yet but have some remote customers and have been looking into the issue. You can also install a pico fuse if you wish. I am thinking a nice push switch and keeping in tool kit.

I've not tested this yet.

I only come across this issue for the first time today (SC564).

So the assumption is Ricoh are only using a low amp quick blow fuse on a new fuser unit so you can only do the SP5810-002 reset once per new unit.

The push switch idea where you can make and break the circuit as many times as you like sounds neat.

But....

Does anyone know for certain if you actually have to ' break ' the new unit detection circuit before SP 5810-002 will successfully execute?
A constant circuit via a small loop would be a far easier work around if it didn't.

Apparently the fuse, described as 'New Unit Detect Sensor' has been issued as a service part, M026-4371. This is used in conjunction with SP5-810-2 to reset these types of fuser issues. Would be a wise idea to also carry spare belt units for these series, D042-4081 and D044-4081.

I have found the part. they want $44.00 plus shipping. Once I get the fuse, what is the procedure for installing and clearing counter. I do have a service manual but I am sure that was written before this fuse became available.

Re: MPC-3502 sc554-00(holy sh..!)

you have to buy a brand new fuser from Ricoh and use SP5810 to reset the code. I don't know if anyone know the backdoor of resetting this sc without a brand new fuser... then share your idea.

If you look back in the thread, you can reset with a thermistor wire mod, use your own pico fuse or order the fuses from Ricoh. $5 each and available...

Re: MPC-3502 sc554-00(holy sh..!)

ok, i had this the other day and as the fusers are on back order it was fixed by other means oh and safely so no bodge fix either. I cant publish on the forum but untill there is a proper soloution from ricoh its a viable soloution which were doing once the warranty period is over.

How can I find out what other means of fixing this code is?

Re: MPC-3502 sc554-00(holy sh..!)

Not on b/o for me ,replaced 3502 fuser yesterday,updated all the firmware first,checked all the connectors as per the rtb,replaced fuser & reset sc code,job done
