Ricoh MPC5503 need firmware file help

[mcbob500]

I have a mpc5503 after it's in energy save mode, it codes sc562-02. Rebuilt fuser all new thermistors and thermal fuses. Looking for possible firmware causing issue. I have firmware print out levels. now at System 1.38 engine 1.39.08

As of 2/15/2019, the most recent System is 1.40. The engine you have is the most current.

SC562-02 A Pressurized Central Thermistor Does Not Reload
Does not reach (T21) degree C after heater 1 ON for (3) seconds.


§ Thermistor dirty
§ Thermistor deformation, float
§ Outside input voltage guarantee
§ After excess temperature rise prevention unit operation

1. Replace the thermistor
2. Make sure that the input voltage is within acceptable limits
3. Replace the fusing unit

All been done, power in is the only thing not done, great now a analyzer. Thanks for the post

I've had a few machines do quirky things, and those all traced back to bad power coming in. Had one throwing random fuser codes every other week, and when I checked the line voltage coming in it was hovering around 113 VAC.

Power company installed a new transformer for the building, 125 VAC line voltage.... no more codes.

Every machine that we installed that was sold by Ricoh direct to a national account came with a line conditioner of appropriate rating.

If by "Line Conditioner", you mean a Surge Protector, those are excellent for voltage SPIKES... but they don't do squat for a voltage "Sag", or low AC Line Voltage. That's one of the reasons I carry a line tester now. Anytime I come across a machine doing random weird things, after checking the obvious on the machine itself I start looking at the AC going to the machine.
