Can't reset fuser after SC544 in service mode on Aficio 4502

[Doug James]

Very Strange... I pu a new fuser in this machine and when I go to service mode 5801 shows memory clear. I checked all the modes 801 and none say clear fuser error. Any help will be very appreciated THANKS !!!

Try SP 5810. You're not the first one to transpose the last two digits.

Tim's right, and it's 5810-002, and you'll also need to install a PICO fuse on that fuser first in order to reset it - unless it's a brand new fuser (which I doubt).

Thanks so much !!!! And I appreciate the lifeline.... Believe or not I have been doing this for 30 years and reset hundreds.... Ugh I feel pretty stupid...

:Like I said, you were not the first one and most likely won't be the last.

Had a C4502 that would not reset and had to replace thermostats and all fuses - everything in the fuser and it started working. Not sure what the trouble was but it went away.

I ripped a door switch out of a MP 201 extra tray and ripped a long length of thin wire from something else, took a old fuse, cut the fuse off the connector, soldered everything up.

You can plug said fuse connector / wire switch contraption into the fuser your trying to rescue, carefully close the door after doing 5810 / reboot. With a MP 201 switch, if i recall the switch was closed the button was not pressed so you waited 2 seconds after closing the door and then held the button down. The machine would return to life and if that fuser was actually ok the machine works afterwards.

I was on a training course for MP C3004 and told the instructor i made one of those up. He plugged his ears and closed his eyes and went na na na na

There was a discussion on that here on CTN a few years ago.
