• Use cartridges that are compatible with the drive type.

cleaning cartridge for cleaning.
• Make sure that you’re using a Universal cleaning cartridge.
The Cleaning LED is lit after a
cleaning cartridge was used.

the Attention LED and
possibly the Cleaning LED.
Retry the operation with a different cartridge.
If the Attention LED is cleared, and then immediately redisplays each time that
a particular cartridge is reloaded, that cartridge must be suspected as
defective.
• Export the cartridge and load a known good cartridge. In some cases, a
cartridge can be worn out, the memory is defective, or was formatted as a
Firmware Upgrade cartridge.
• Any cartridge that is suspected of being defective or contaminated must NOT
be reused in any drive.
• If the bad cartridge is a cleaning cartridge, it might be expired.
