Cleaning the read/write heads
Use the following table as a guide for cleaning the tape’s read/write heads. You should also clean the tape
heads if the Clean/Attention LED is lit.
Caution Only use an HP Cleaning Cartridge (HP 92283K) to clean the tape heads. Do not
use swabs or other means of cleaning the heads.
The cleaning requirements for the DDS-3 tape drives are significantly different
from those for HP’s previous DDS products.
Once your backup routine has been established, you should have an idea how many tapes are used each day.
Remember that HP recommends cleaning the drive’s tape heads using the intervals shown in the following
table, or if the Clean/Attention LED is lit. Using this table, you can estimate how often the heads will need
cleaning and build the cleaning operation into the backup routine.:
To clean the tape heads:
1. Slide the cleaning cartridge into the drive. To tape drive automatically loads the cartridge and
cleans the heads. At the end of the cleaning cycle, the drive ejects the cleaning cartridge.
2. Note the date on the label on the cleaning cartridge so you know how many times it has been used.
Discard the cleaning cartridge after it has been used 50 times.
Note The cleaning cycle takes about 30 seconds. If the cleaning cartridge ejects in less
than 20 seconds (and the Clean/Attention LED is still lit) it probably has expired
and no cleaning occurred. Replace the cleaning cartridge and repeat the process.
3. After the tape heads have been cleaned, take the cleaning cartridge out of the drive and write the
date on the cartridge label. This record tells you how many times the cleaning cartridge has been
used. Cleaning cartridges have a typical lifespan of 50 cleaning cycles.
