To clean a drive, use only an approved cleaning cartridge (see Figure B-4).
You can use a DLT cleaning cartridge approximately 20 times before you
must replace it. The cleaning cartridge and data cartridges are always
different colors.
Figure B-4 DLT Cleaning Cartridge
Loading a Cleaning Cartridge
To clean a DLT drive:
1. Load the cleaning cartridge into the drive and close the handle. The
drive automatically detects that the cartridge is a cleaning cartridge; it
buzzes, then loads and runs the cartridge. After about 1.5 minutes, the
cleaning is complete and the “tape in use” LED glows steadily.
2. When the cleaning cycle is finished, press the “unload” button and wait
for the green “operate handle” LED to light before opening the handle.
3. Remove the cartridge from the DLT unit.
4. Make a note in a log book, or on the cartridge itself, that you used the
cleaning cartridge.
