Tape Drive Needs to Be Cleaned

My former employer, now client, has a Model 250 with an internal tape drive
(6382 Model 001). Typically it needs to be cleaned every one to two months.
Lately the system started issuing the message (CPF6792) every week. This
week it has issued the message every day, despite the fact that, according
to the bookkeeper, the cleaning cartridge has been inserted and run every
morning.



The nightly backup seems to be running successfully, and I run the PRTERRLOG
(Volume Statistics) every weekend, which has not indicated that any tape
needs to be replaced.



So, any idea, clue, or suggestion why the system (V5R1, if important) tells
us that the drive needs to be cleaned?



Another thing, which I have always wondered: How does the system know that
the drive needs to be cleaned? The answer may offer a clue to the original
problem.



Thanks.
