I know this has been treated many times before on this forum, but is there an other solution than to replace the fusing unit with a new one?
I replaced the thermophile inside the machine, and al the parts of the fusing unit...
Man, how thankfull i would be if anyone give me that hint
Nice weekend!

The one thing that stands out from all the posts on this topic, is that replacing the unit is the only permanent fix.

If you compare the cost of the parts + callbacks + labour and downtime: where is the saving?

Not to mention testing the customer's patience to the point that they demand the machine be replaced citing reliability being flaky?!

Some techs believe that the fusing frame becomes skew over time that it causes all the unexplained codes - I don't know for sure.

If it was me - i'd replace the unit and know that it IS fixed.

Unfortunately not. You can replace every single part of the fuser and it will STILL code. Save the heartache, fit a new one.

If you have another machine, swap out the fusing units. If the problem moves with the fusing unit, the fusing unit is bad. If the problem stays with the original machine, check/reseat CN 257 on IOB, replace IOB, replace PSU.

Thank you guys for responding so quickely...
I give up and will replace the unit, but, do you know where to buy a cheap one, here in Europe?

i've already swapt and the problem stayed with the machine... But i have had this also with another machine and it only went away with a whole new unit...
