Cleaning the Heads

Cleaning the Heads

The DLT7000 tape drive does not require periodic or scheduled cleaning based on time or usage.
When the heads in a tape drive need to be cleaned, the tape library displays a message on the operator panel and also informs the host computer over the SCSI channel.
Use a digital linear tape cleaning cartridge to clean the tape heads.
Figure 31 lists conditions for when to use the cleaning cartridge.
