Are you tweaking the connectors on the front or the rear side of the fuser ? I will have to try the panel off timer off thing I didn't think you could turn it off totally.

So who do you work for in Albert Lee ? Ikon ? I am with Ricoh in Minneapolis.

We had allot of problems with this at one time. I found that the rear thermistor, mount would get out of position. Especially if was not used frequently. Heating and cooling causing bracket to move away from roller. My solution was to bend bracket until one piece of paper would firmly slide from under thermistor. Hope it helps

Just thought I might throw another idea in the mix.

Do any of the machines giving this code have ESA transformer or Enhanced Locked print installed on them. I have heard of an older version of ESA transformer client causing fuser codes. A newer version fixed the issue. A long shot but something to consider.

I've got about 12 of these at a govt installation. I was getting one or two calls a month for SC555's. I finally decided to try some t/s on one that was throwing the code every two or three days. I changed the AOF to off and the problem stopped. Went back a couple weeks later to turn it back on with the expectation that I would start getting the codes again. Hasn't come back since.

Go ahead and laugh. I just figured there was no way in hell that every one of those machines had bad thermistors. They all made the cutoff for the newer version thermistor.

I think there is a power/firmware issue going on here.

Nobody will laugh...AOF is a key for many problems related to fuser codes and not only. I had one weird jamming problem on a 4000 SP caused by damp paper (problem debated on this forum) and the fix was as simple as turning AOF off. Is still off since than I believe me or not I never received a call from the customer in months.

I tweaked the connectors on the front and rear side of the lamps. From the factory they are a bit loose. When I was testing them, I cheated the door and then wiggled the connectors and I would get codes. It seemed to help out my issue.

I work for Metro Sales Inc out of Owatonna. I currently live in Albert Lea, however. How is business up in the cities?

New brackets are available. You will found them in one of the bulletins for D062 but are good for all series starting with B140.
Right now they are back ordered in Canada and USA.

I will have to check the connectors too I have just been turning off auto power off and that seems to fix it but I suppose I will end up with flat pressure rollers.

My area has always been slower because I don't have many 35 ppm machines I can always find things to do though. I think there has been less emergency calls in general. Are you guys busy ?

It is definitely picking up here in the past few weeks.

I had a MP6000 which burned me many times with this code. My solution worked and I haven't been back to that machine since (knock on wood).

Step 1:

Check the lamp connectors (females specifically). From the factory they split and are not making good connection. I took my tweaker and pinched them so they were tighter. Depending on which lamp connectors are loose, you will get either 555 (fror the one lamp) or 546 codes ( for the other lamps). When I cheated the front door and would play with the lamp connectors I could get the machine to pop those codes, that is how i knew those connectors were an issue.

Step 2:

Per Ricoh, disable the 'panel off timer':

1) User tools
2) System Settings
3) Timer settings
4) Panel off timer, turn to off.

Let me know if this works for you, because I worked diligently and it seemed to work for me.

We had a MP7000 that was throwing SC555's. A tech was at this account at least 3 times a month. We did all the updates, replaced thermistors,disabled AOF, etc. No luck. Replaced fusing assembly, wiring harness (pain in the @$$), and the power supply. Problem came back. I had my tech disable the 'panel off timer' and haven't heard from the customer in over a month.

Our RTM told me today that there would be new firmware released in a week or so to address the fuser codes. Hopefully this finally resolves this issue.

New brackets released are good for nothing....In all the accounts installed the number of calls increased SC 542 and SC 545 looks to be in the top 3. It looks like the new brackets are like a magnet for paper dust/toner mix.
In this thermistors/thermostats issue are to many variables and in my opinion it's not just only one solution for our problems. Sometimes you can fix it just replacing the thermistors...sometimes just forcing the fuser to idle way longer than usual....(this one is actually the best) cause it's cleaning the thermistor from debris.
When you are out of solutions after replacing the thermistors, thermostats...checking the lamps connectors, fuser harness, try to increase the idling time SP 1103-01, 02, to 60 sec and 3 to 120 sec. If still no results try to turn off AOF and also turn the Panel timer off...
