Cleaning

To clean the tape drive:
1. Insert the cleaning cartridge into the tape drive as you would
a data tape cartridge.
2. Observe the green LED blinking slowly to indicate that the
tape drive is automatically performing a cleaning cycle.
NOTE: If the cleaning cartridge has been used for more than
approximately 30 cleaning cycles, the amber LED will blink
rapidly. Press the unload button to eject the cleaning
cartridge and discard it.
3. Remove the cleaning cartridge after it is automatically
ejected following the cleaning cycle.
You can use the cartridge tape drive immediately after cleaning.
