Check the fusing unit connector in the machine.

Update the firmware

Update the firmware

+1 its a well known firmware issue that's been fixed on various machines for sc 553 after coming out of energy save.

X2, yep, a firmware problem

Re: MP 5500 with SC 553

the failure is th right conecting of heaterlamp the start up in wrong way change it and its finished your problem ( i have 8 of this) No0 firmware helps no new thermistor no PSU. they have a series of default wrong conected heating tubes

Are the color marking wrong?

Re: MP 5500 with SC 553

I'm not sure I understood the post of Flo,seems to me he talks about that SC is generated if G,B,W heater lamp connectors aren't fit in same collor connecting sockets,but that mistake generates SC 542.
I made that mistake only once back in the days...nowdays it's first thing I inspect on faulty fuser,that fuser is working good in diferent machine.

I mean that 2 of the heater lamps are not correct conected and by wake up they bring the codes, in progress work they never show up any codes Sc542 only bring upper end Thermistor when small Tube is conected at high tube position or Thermistor is dirty. I look long about this problem and what luck i get second Machine for Changing Parts to test after Fuserchange new machine also have same probs and i look all there and finished with heaterlamps they dont stay correct to warm up Hotroller enogh at startup

Re: MP 5500 with SC 553

he means some little jap dude put the fuser lamps in the wrong way round when he built the machine.

Still that doesn't cause the SC just update the FW

Re: MP 5500 with SC 553

Uh firmware will be tough one for me,no one in our workshop dealt with it so far,I did some language changes once but entire firmware will be tricky.
We don't have access to tessa...we fix refurbished machines,but I beleve I can obtain firmware,and I suppose service manual will lead me true it...I just hope I won't make a bigger mess out of it

just insert sd card in lower slot, turn machine on and select the firmware, press update, wait until update done show in display, no fuzz at all.

I can provide the firmware if needed.

Da Goose say:

Fusing thermistor error - Enter sp mode 1106 & check for inconsistancies between end & center temps. Possibility of a defective fusing lamp.

Fusing thermistor error, BICU defective

Fusing thermistor error, IOB defective

Fusing thermistor error, PSU defective

Fusing thermistor error, Thermistor defective

Re: MP 5500 with SC 553

Last fuser i had do this was the day after another tech used the fuser to test a different machine. What i did was replaced the thermisters, then you know the metal plate with 3 screws in it on the rear side of the fuser you take that off to expose the lamp wiring and such check the wire that comes up and bends over to the top white connector, its supposed to be routed through the hole if it gets routed to the outside it can get pinched by the metal plate, the one i checked was just enough that the coated was cut into i taped over the pinch with electrical tape and routed it correctly, then because these are known for sc's i usually take a needle nose, look into the big black connector with the flat metal pins i usually give them a slight twist, not a lot just enough so i know they are contacting the machine harness, i think i have also put washers between the harness and fuser frame where the two screws mount it there are several TSBs on these fusers for thermister SC. anyway i believe the pinched wire was the culprit that was months ago and no ones been called back to it since.

input all the setting,use the setting kept in between the front door and that will help,i did the same thing reset the engine.and that solved the problems.i mean to say go to service mode and use that settings to input.
