feel sorry for you guys - we just put brand new fusers in. By the time you have dismantled them and rebuilt, then sorted out the various issues ....

Nice when you or your boss can afford it, but being an Indy having to compete with the fat cats thru prices I prefer to rebuild them. We use those "German UFR's", recoat the thermistors with teflon tape and let the fuser unit have another life. Some machines we do this 3 times. Our 230VAC lamps rarely fail btw.

It takes 20 min. You make more than a doctor for that time!

I'm not surprised at all Hans. Allan is one of the best techs here as you already know.
Moreover he is creative and humble good man in his will and I'm just glad he is on my friends list

Hey thanks for the compliment, don't feel deservant at times.
Great tech not so sure about that, hard headed and persistent i am pretty sure of.
Only as good as my support and that includes guys like you.

Yea and its true rebuilding units are that profitable.

Going to work in this ever diminishing Rand value.

New fuser would be about R3750.
Rebuilt kit R750.
So about a R3000 savings on part cost!

That would be around $157 for 20min.
So $470 less overhead and stuff per hour if you do noting but rebuild 363 fusers for dealerships.

Can you do it in under 20min. Now starting to doubt.
Know i can replace drum, dev, collars, blade, transfer roller and fuser parts in under 45min.

We replace transfer rollers about every 3rd Image Unit rebuild. The white finger on rear side of transfer roller frame that contacts drum gets worn down & scrapes drums. Love to find a source for those white fingers without buying OEM entire T. Roller ass'y. I/m stealing low meter ones off of old dead soldiers but they're almost all gone. Looks like there's a subtle difference in length of roller & plate on a BH200 series but finger may still work in BH223 series. Anyone try that?
Have a nice pic. but for some reason I can't attach it.

Don, I got them long time ago from an After Market supplier. The did not fit well and I had to use a cutter knife to make them work. Will try to find that supplier again for you if you want. Have still a bunch in stock.

I wrap two layers of Teflon tape around them. Looks horrible but seem to work even on those badly used.

Here is another machine with the Teflon Tape on the stands after about 80k. The stand was already "mooned out" before I put the tape. (btw note the collar I made for the transfer roller. It is similar to the Image Unit collar having an integrated bearing too.)

Still, even with modified machines having the Teflon tape and the transfer roller collar, the drum will have scratches but it takes a lot more longer than without. I use after market toner for all my machines (yes, I'm an Indy....) but have the unconfirmed impression that machines from customers buying on their own original OEM toner are less suffering from this problem. Could it be that there is in the OEM toner a substance causing less friction such as a kind of wax?

Now i need to get some Teflon tape.

What helps a lot for me it to cut the spring that pushes the guide up by a turn or two and that reduces the friction by a lot.

I modeled and 3d printed the parts, but did not test them yet. The model should be accurate but using PLA or ABS plastic would not be ideal.
Never wanted to scratch a drum up just to test them...

The B250 roller assy does fit and work with no issues if you had some of those.
