I have a CS 2551ci with grey background on the front of internal prints that kind of looks like a dirty charge roller. The back side of a single sided print has grey streaking that resembles cleaning blade failure that stops abruptly after about three inches from the lead edge. I first suspected after market toner, but this is not the case.Re-flashed the machine with latest firmware. Tried a new developing unit, new toner cartridge and swapped drums between two other colors. All supplies have around 50,000 prints and were done in December. (except the Dev., which is now new) Appears all the grounding spring are clean and intact, with relatively no misting in black. (a bit in magenta) Fuser looks great, and even the secondary transfer roller was relatively clean. The problem diminishes on longer runs but never really totally clears up. Any ideas on this one? Anyone out there seen this bat-shit crazy behavior before? I've attached a sample.
