DDS4 tape drive

The DDS4 tape drive uses a dry cleaning cartridge. Each cartridge is good for about 50
cleaning cycles. Regular cleaning is recommended to maximize tape drive performance.
The cleaning schedule depends on the number of DDS tape cartridges used each day for
backups. Use the following table to determine a cleaning schedule.
In addition, if the Clean LED flashes, either the tape drive heads need cleaning, or the
backup tape needs replacing.
To clean the tape drive:
1. Load the cleaning cartridge into the tape drive.
The cleaning cycle begins automatically, and the Tape LED flashes. When the cleaning
cycle is complete, the cleaning cartridge is ejected automatically.
2. The first time you use the cleaning cartridge, recor d the date on the cleaning car tridge.
Each time you clean the tape drive, mark an X in the box. After all boxes are filled,
replace the cleaning cartridge.
3. Return the cleaning cartridge to the plastic pro tection box.
If the Clean LED continues to flash, repeat the cleaning procedure using a different
cleaning cartridge. If the Clean LED is still flashing, repeat the backup operation with a
