[Error Code] MP6002/7502 too many Fusing SC

[Guest]

Too many fusing SC are coming up and the machines stop. I have to visit the sites and cancel the SC each time the SC showing up. Is there any way to decrease the number of SC?

What SC's are you getting?

I've reduced my fuser SC calls with careful positioning of the thermisters (and generally new thermisters while I'm at it) so that the actual chip is right over the heat roller. I find on many occasions the position is off which allows too much delay in reading temperature, or a small build-up makes marginal positioning fail. I'm the only guy in our branch taking the time to do this and I get the fewest of these issues, so I believe it is fairly effective.

Setting 1103-003 to 240 is a massive help too.

Clean the thermistors every time you go near the copier and replace them at every PM, 300k to 350k.

I have three large law firms in town with 25 Martini copiers between them. Every month I go around them all checking to see which is due for a PM or any other remedial work. Part of my routine is to clean the the thermistors and have dropped the fuser SC's from 8+ a month to one or less.

Another trick is to fit a new hot roller drive gear every time you change the hot roller. A bit of analysis of call backs showed that around 20% of gears failed within 50k of the roller being changed.

Does this effect the run time any? I remember one of the earlier US Sc555 bulletins adjusting various Fuser SP's that would make the copier go thru a "Please Wait" idle cycle for about a minute or 2 after running the 1st job before you could run the next job. That's why I quit using it & went with the TESSA fix I found here instead.

You would be better served keeping track of all of the other suggestions here.
Still, unexpected fuser errors can be caused by unreliable power from the outlet the machines you are dealing with are plugged into. You might think about that being the case if you can reset the errors rather than replace thermistors and such. It is that time of year here in the northern hemisphere after all.
There really isn't a whole lot to be done about that either. Under ideal conditions, a UPS would take care of that, but machines that use thermal fusing typically draw too much current for UPS use, and I have also been led to believe that those types of machines require a direct connection to safety ground to work properly as well and a UPS isolates all leads in from the outlet. A good line conditioner would probably reduce the occurrence of the errors, but it won't eliminate them altogether.
Well, good luck, and sorry if this was a waste of time.

What SC's are you getting?

Mostly SC542, sometime SC555

Besides the very good suggestions from other techs to your post, you may want to check out the following 2 Technical Bulletins that specifically relate to the SC555 and SC542 errors.
