Bizhub 250/350 eating drums

[Hansoon]

Just discovered that the # given in the Italian instruction is that of the collar for the Di-183 series. This collar is NOT the same as in the Bizhub or Di-250/351 series. The collar for the Di-183 has a diameter of 18.35mm against 18.60 for the Di-250/351 series machines. I cannot imagine that this will work though the drum has the same diameter in both machines, the mag roller is slightly thicker. Perhaps that's why the collars must be slightly larger. Furthermore, when the mylar seals at each end are damaged they need replacement too at the same time.

Just yesterday KonicaMinolta Italy sent a new technical notice that in short tells that the problem is caused by the two collars of the developing roller. They suggest to change the DS COLLARs (p/N 4163529801) every 40.000 copies.

P.S.: I'm sorry but the attached file with the procedure is nly in italian

I've seen right now that there's the same technical notice about BH 222-282-362 models. NEW MODELS OLD PROBLEMS.......!!

P.P.S.: i apologyze but i did a mistake : the right p/N of the collars is 4163529801 and not 416352981. Sorry!

4163529801 (4163-5298-01) is the # for the Di-152, 182 collar. NOT Di-250, 351.
