Use Cleaning Tape LED

If an excessive number of read-after-write errors are detected during normal operation of the 4000/7000DLT Series, the Use Cleaning Tape LED will be turned on by the drive.

Usually, the Use Cleaning Tape LED is turned on by the drive because of a dirty head, so the head should be cleaned and the operation tried again.

If the Use Cleaning Tape LED is again turned on and this seems to be a cartridge rather than a drive problem, make sure that all the data on that cartridge is backed up to a new cartridge by doing a complete backup from the source drive, if necessary. Then discard the old cartridge. If you are unsure of the problem source, call customer service.

The Use Cleaning Tape LED is normally turned off by executing a cleaning cycle or by cycling power to the 4000/7000DLT Series.
