Mpc 4502_5502 new fuser detect fuse.pdf Oh, and here's a copy of the RTB for the 4502 series for those who don't have it.

Yes. There are also a couple of other threads with suggestions for what to do when yo do not happen to have a fuse.

Thanks for responding...............I see that some guys are wiring a push switch to rest the error.......pretty slick, but since the OEM fuse is available real cheaply from Prec Roller part # M026-4371 for the MP C4502/5502 series. Since you are sure that the same fuse works for the 5503 also............I'll order it and give it a try. The fuser is rated to last 400K and only has 100K on it and looks to be in good condition. No sense in charging the customer for a rebuild. I'll also have to verify it has the latest firmware. Ricoh tech bulletin said it needs to be at least Ver 1.22.08 or better.

When the c5502 was new I used to run into the Sc544 a lot, but I haven't seen it in years now.

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.

Ok , so we all know the following(for the MP C4502 series machines):

When the machines suffer a fuser overheat error, it is not possible to reset the error in SP5810 as it was with previous models: The reset fails when you try it because Ricoh added a fuse to the fixing unit - with this fuse the code can be reset on the C4502 series. The fuse is included with the fixing sleeve.

My question is this............we have a MP C5503 copier with the SC-554 code. Does it use the same reset fuse as the 4502/5502? Signed on to Ricoh TSRC and found nothing to clarify if that same reset fuse part works on the 5503. Comments appreciated. Thanks in advance.

Ok, So based on the advice given here we went out with a new unit detect reset fuse for the MP C5502/4502 series and it does not work in the 5503's. So disregard all the advice that was given in the above responses. I'll figure it out and post what the real fix is.

Re: Ricoh MP C5503 SC544-02 code

Maybe the fuse did work but your fuser sleeve is indeed faulty at only 100k?

The 5503/4503 fuser is different and there is no place to plug in the MP C4502 reset fuse. The connector for that reset fuse is available on the 4502 and 4503 series fuser only. If there is a pico fuse on this model......it must be in a different location. Couldn't find it though.

Updating the machines firmware as per Ricoh tech bulletin and ordering an entire fuser.

Re: Ricoh MP C5503 SC544-02 code

this is a color machine and many if not most customers that have a color machine aren't sticking to normal 5-6% coverage per color. your 100k could be 600k worth of copies/wear and tear if you check your logging data. with going with higher coverages different types and thickness of paper constantly being ran thru color machines makes making money on color MA's a nightmare

Pico reset fuses Ricoh.JPGOK, To clear up the confusion I promised I would get back with the correct info for this issue................The pico fuses(see pic) are different for the MPC5503 series. Different size connector and the connector is not in the same location as the 5502/4502 series. The 4502 reset fuse is the smaller connector----has a part number as seen in the pic and can be ordered separately. The 5503 reset fuse is taped inside the box when you purchase the fixing sleeve assembly Part#D150-4041 and is not yet sold by separately.

On the MPC4502/5502 series the reset fuse connector is on the back of the fuser to the right of the big blue plug connector. On the MPC4503/5503 series you have to take off the lower cover to see the reset plug.

Hope this info is helpful to someone in the future..................

P.S. .......really sucks that we need a reset fuse to accomplish what we could always do before just by going into service mode.

Re: 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.

Re: Ricoh MP C5503 SC544-02 code

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.

Re: Ricoh MP C5503 SC544-02 code

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!
