6.1.1
Using the Cleaning Cartridge
Note: To prevent contamination of the unit and damage to the heads, do not use the cleaning
cartridge for more than the manufacturer's specified number of cleaning cycles; and do
not attempt to rewind the material in the cleaning cartridge and reuse it.
1. Insert the cleaning cartridge into the drive. The drive automatically takes the cartridge, loads it,
and cleans the heads. After about 30 seconds, the drive ejects the cartridge.
Note: If the cartridge ejects after 15 seconds, the cartridge has reached the end of its useful
life, and no cleaning has occurred. The Cleaning Needed LED might still be lit so
discard the cartridge and repeat the cleaning operation with a new cleaning cartridge.
2. Take the cartridge out of the drive. Write the date on the label of the cleaning cartridge to
provide a record of how many times it has been used. Do not use the cleaning cartridge more
times than specified by the manufacturer.
