Is it ok to use the 50PPM fuser in a bizhub 421 ?

[EarthKmTech]

For reasons out of my control, this is all i have on hand to go into the machine.

Will it be ok ?

I have in the past had error codes when accidently putting the 42ppm fuser in a 50ppm machine, but havent ever tried the other way round...

I didn't tried this in BH421, but I had the similar situation in BH420 - someone installed fuser from BH500 by mistake (or just didn't realized that they differs).
If you really need, for a short time (I had 2 weeks) - you can use this fuser, machine will neither burn nor blow away, just from time to time, _after_ longer jobs it will show a code C-3501, short jobs are ok - but it would be nice to instruct a user how to reset fuser error codes in case of problem.
