After the cleaning cartridge has been inserted, the remainder of the cleaning
process is automatic. The 7206 Tape Drive:
1.
Loads the cleaning cartridge into the tape drive
2. Cleans the drive by moving the cleaning tape forward for approximately 30
seconds
3. Unloads the cleaning cartridge when the cleaning operation is complete
4. Indicates a successful cleaning operation by turning off the Fault status light (if
the Fault light was on prior to the cleaning process; otherwise, the Fault light
remains solid to indicate that the cleaning cartridge is no longer usable)
If a system error occurs, clean the drive and retry the operation. If the operation
fails, replace the data cartridge, clean the drive again, then retry the operation.
To determine how many times a cleaning cartridge may be used, check the
information printed on the cartridge. If you attempt to use a depleted cleaning
cartridge, the 7206 Tape Drive automatically detects the error and ejects the
cartridge. If the Fault status light was on prior to the cleaning process, it stays on;
if the Fault light was off, the depleted cartridge causes the light to come on.
