Until you identified and correct the exact cause of the problem, 5801 will not help. It may clear the code but the machine will immediately code again. When you cycle power, open the front door before you turn power back on. This will prevent the engine from starting which prevent coding again. If the code is still there, it was not cleared. Enter SP mode with the door still open and check the temperature of both thermistors. They should both be in the mid to upper 20s. If one is 0, negative or extremely high, there is a problem involving that thermistor.
Thanks slimslob, i have opened the doors and cleared the error. screen was error free for a few seconds apparently waiting for fuser to warm up. then after about 30.40 seconds bam!! sc 552.
so i checked the thermistor temperature and they both alternate between 17 -19.
i think the main issue stems from the fact that the fuser unit does not kick in or move at all. rollers do not turn and the new lamps i replace do not light up.. any advice would be appreciated thanks everyone. am still here after so many hours.
Recently had the same issue with MP6500, replacement of the (IOB) Ass'y NO B2475128 was the fix and it took me a day to figure it out.
you can swap one if you have one on hand.
Note: Be careful with Dip switch setting when replaced.

Considering this is an old box I would swap out a backup fuser unit i know works.
IF no backup,check lamps are good and in the right location...Thermisters are cheap so is UFR which can cause fuser codes..
TRY spacers on the rear connector for fuser to make better contact with rear of copier..
I think most of us went thru a learning phase wth these series and phantom fuser codes..............
If the heater lamps are not connected to the same color on the terminal strip on the rear of the fuser you will get a code. Green to green blue to blue.
