Got to admit I've been wondering about this myself. I've a 3584 library with
10 LTO drives that has been in service since September of last year. I've
got three cleaning tapes in the library, I move 130 GB of data per day --
and I haven't seen a cleaning tape used yet. I know the drives and tapeand I 
haven't seen a cleaning tape used yet. I know the drives and tapes are
supposed to be self-cleaning, but this is almost to good to be true.
 
OTOH, I haven't run into any errors that indicate dirty drives. . .

The trick is that you have to insert the cleaner cartridge into the library
through the I/O station on the door of the library by using the MOVE MEDIA
command that you run from the front panel of the library. (Not to be
confused with TSM's MOVE MEDIA command.)
