B296, D011, D012;13 mag roller coating

[Guest]

Have you guys seen this issue of the mag roller being coated and releasing toner onto the developer lip? It eventually forms grey copies, and has a fix out for it in the way of TSB's B296-014

and D011-34

These machines both take the B296 toner and developer. They both have the same problems, but we have been told by our rep to wash the coating off the mag roller with alcohol, and then put on a coating of Brillianize making sure to buff it off.

They aren't accepting warranties from us on these parts yet, and I hear that they are changing the toner chemistry to fix this, as well as the new mag shells that are available. In the meantime we are left with ticking timebombs out in the field all ready to fail and requiring extensive man-hours to repair.

What I'm asking is how you all have been coping with this issue, and any ideas from your reps on how they could have screwed up so much. Our current theory is the toner is so fine that at "regular" temperatures, it bakes onto the mag shell. This is ridiculous that it could fail so easily and not have a solution that could be implemented to repair this.

Toner chemistry...fixed. We released a new toner...EDP number different...Serial number has an "A" at the end...
Please check previous threads about this 5000SP problem....debated on a large scale by many of us.

b296 mag roller coating

there's other bulletins on this as well. I don't have them at the moment, but one suggests bumping up the charge roller, DV and ID bias by 100 points each. The unofficial suggestion is a drum ground strap part # A0962341.
This screws into the HV board bracket behind the board and over to the center of the drum flywheel (for the mp3500). Not sure of the positioning on the MP4000's as I haven't had to do one of those yet, they look quite different in the back. I figure the real solution will only come when Ricoh figures out how to make the toner and DV properly.

Sorry if all this is old hat to you but I'm trying to spread my own knowledge around wherever it might be useful.

I've seen some of the threads, and I'm glad that there is something being done. Thanks for your quickreply, btw.

What I'm wondering is how is the transition going and how much do we have to do to prepare the machines for the new toner. If developer replacement is required, is it going to be covered under warranty, plus are the mag rollers going to need to be changed even with the new toner. The information on the new toner wasn't released to us by our rep, and we are having multiples of multiple failures. If we don't have to change the developer, what is the procedure for integrating the new into the old? I haven't found TSB's regarding this, any help would be appreciated.

Thanks again, Rooster.

Latest official solution is to replace the toner with the new type (it's for 3500/4500 as well as for 4000/5000).
If your mag roller is not coated already (I doubt it) no further action is req except voltages modification.
SP 2201-01 560 V
SP 2201-02 400 V for customers with volumes over 30K/month set to 460V
SP 2001-01 increase with 1500V
SP 2001-02 250

This set up is for the new type of toner.
I suggest to order the new dev unit PN D009-2301 for 4000/5000
For 3500/4500 new dev unit PN is B213-3011 or just order the new mag roller B082-3101

For the old toner
SP 2201-01 increase to 660V
SP 2201-02 increase to 500V
SP 2001-02 increase the existent setting with 100V
Use the new dev unit
Good luck
