The only maintenance the DAT drive requires is cleaning of
the read/write heads.
The performance and reliability of the DAT drive depend
upon its operating environment. Make sure the DAT drive
operates within the environmental restrictions listed in this
chapter (refer to "Environmental Requirements").
During normal use of the DAT drive, the read/write heads
pick up residue from the DAT cassette. The heads should
be cleaned at the following times:
After every 10 hours of use or more frequently if
required.
If
the media warning is displayed by the busy lights (see
Table 5-3).
You should clean the heads with the cleaning cassette that
is provided with your DAT drive. To clean the heads, follow
the instructions on the cleaning cassette case.
If
the DAT drive requires service, perform the following
steps:
1. Contact your local Hewlett-Packard Sales and Support
Office.
2. Explain the problem you are having with the DAT drive.
3. State the serial number of the DAT drive.
If you have any questions about the warranty on your
drive, please contact your local Hewlett-Packard Sales and
Support Office.
