OK, reviving the old thread.. after a year...
I sorted buzzing (bad caps in PS module, repaired).
I have new toner cartridges, new Laser module, new flat cable, new processor board.. and still the same problem (most of the time).
The only thing left to replace or repair is high voltage unit, or some ground contact or similar..
I suppose there are no experiences with this or similar problem solution and Samsung printer in the meantime?
