Youre mentioning end of life, and the fuser. So im assuming that the end of life message you are getting specifically mentions the fuser?
And have you replaced any parts already?
Lets remove the fuser then.
and while its removed, unplug the machine, wait five minutes, plug it back in.
And then, reset the counters. Only then, insert the fuser. Any change?
That would be worth a shot.. Once you have returned the original unit.. reset the counters ..
Verify how it behaves.. And then remove the unit, reset counters, insert unit, reset counters.
If that doesnt work, youre going to have to replace the chip on the imaging unit, you can get the needed reset chips here http://amzn.to/20wOEB0
the drums also have counters ( and chips inside them that keep track of the units usage )
It would help if I knew the exact word for word error you are getting on screen. And any codes along with it.
That tells us its the black imaging unit you need to replace.
Is black the one you replaced?
Then you need new chips on those imaging units.. Or you need to replace the imaging units. Its much cheaper to get the new chips.
And this video is very close to your model, and shows how to replace those chips.
