[Error Code] MPC 2500 with 553

[Guest]

I have an MPC 2500 that is popping a 553 in the morning not every day, but a lot. It runs the rest of the day, but I also noticed that the code doesn't always show up on the SMC when it does pop. There is also an associated 991 code. Ricoh said to put the fusing idle time up to 30 sec. We'll see if that works...

I had that problem once and i solve it only by replacing the Fusing Unit.
I tried change the thermistors, Power supply, BICU, upload firmware, nothing works.
But i think i didnt tried to do the procedure that you are saying. If it work say samething ok?

Might be worth checking this as well before fitting a new fuser


[Problem]
SC 553 Heating roller overheat (software error)
Answer [Cause]

• Heating roller temperature stays at or above 230 degrees C for more then 1 second.

[Action]

• Check temperatures with SP 1-106-1 for Center and -2 for end.
• Confirm that the IH Coil fan blades are spinning. We have had reports of the motor running (so no SC532 is detected) but the fan blades are slipping on the shaft, this then causes the heat roller overheat condition.

You're talking about an MP C3500, instead of an MP C2500.

ooeerr, back to noob class

LOL!!

I've had the same with an MP2000. Every few weeks SC553. Replacing the whole Fusing Unit resolved the problem.

Increasing the idle time took care of the problem. Client hasn't called since I posted so we'll call it a win. Thanks to all the people that responded!

Hello!!!
Could you please tell me what SP did you change?

Seems there's quite a few pieces of advice right here in this thread, yet you haven't mentioned trying any of them. Why not tell us what you've done (other than reset the code) that hasn't solved the problem, and we can go from there?

Hi John, It seems to be due to the Sponge Hot Roller deteriorating in some way. Either by a reduction in diameter due to wear and tear (high mileage), or the sponge material changes its properties in some way. Either way.... change the sponge Hot Roller AE01 0054 and you will probably find the problem goes away. The new diameter is 35.0 mm. I found if it gets below approx 34.4 mm diameter (particularly in the middle section), you must change it to avoid the SC553 error. Happy days.
Incidentally, while you are in there, make sure the Pressure Roller has not deteriorated and become smaller at one end. That leads to Belt migration.

Welcome to CTN.... but John's problem is over 3 years old, AND he hijacked an even older thread to post it.

Re: MPC 2500 with 553

Yep, I know its an old issue. Its taken me almost that long to find the apparent answer. and "being old" is not a good reason to stop updating readers on this frustrating issue. (N.B. ALL other avenues have been explored and the Hot Roller deterioration is the last and best suggestion.

The thermostats in front of the fusing belt are unstable/old - we changed them and fixed the problem.
