Cleaning the Tape Heads

When to Clean the Tape Heads

•
If the Drive LED is flashing rapidly, a hardware fault has occurred. If this fault
occurs immediately after powering on the drive, then the Power-On Self-Test
switch is enabled and a Power-On Self-Test has failed. If the front panel LEDs
flash together, contact the Seagate Technical Support department for
information. If the Drive LED is flashing rapidly during drive operation, attempt to
remove the tape by pressing the eject button. If the tape does not eject within 2
minutes, press and hold the eject button continuously for more than 5 seconds.
The tape should eject within 40 seconds. Contact Seagate Technical Support for
more information.

If excessive dust or debris from the tape media collects at one or more of the tape
heads, your drive might not be able to read from or write to the tape. To avoid this
situation, you must clean the tape heads on your DDS in the following
circumstances:
•
after every 50 hours of operation
•
if the Clean LED lights up or flashes
•
If the Media LED flashes during drive operation.
Meaning
Cleaning is required because the drive has been
operating for at least 50 hours.
The internal error rate threshold has been
exceeded and cleaning is required.
The cleaning cartridge in the drive has exceeded its
useful life. Replace the old cleaning cartridge with a
new one.
A cartridge is inserted and is not generating
excessive errors.
The drive could not write to the tape correctly (a
write error has occurred). Use a DDS cleaning
cartridge to clean the drive.
The drive is reading from or writing to the tape
normally.
A hardware fault occurred.
