This CS-500ci is in our office. For the last two weeks I've had various people tell me that the machine makes noises, and I've heard the noises for the first time today.
It makes a brief groaning noise (4) times at the beginning of initialization, and occasionally the same (4) repetitions when awakening from sleep mode. After the (4) little groans it doesn't repeat again for long periods of time.
After quite a lot of head scratching, I could reproduce the sound by running the Laser Scan Cleaning function in System Menu > Adjustment/Maintenance (except it's (6) little groans when run from the system menu).
When the (4) laser slit glasses are cleaned by the rubber blades, the mechanism is driven by couple of cams. To get a look at the mechanism just remove the drum and developing units. The cams are at the LSU unit top left, visible through the black drum opening. A little dab of white grease will quiet it down quite nicely.
Maybe this will save someone a few recalls. =^..^=
