Exhausted Cleaning Media If a cleaning tape is inserted into a DLT/SDLT drive and the light remains on after the tape ejects, this indicates that the cleaning tape may be exhausted. Refer to Table 5 to ensure that you are using the proper cleaning tape for your drive type. If so, try a new cleaning tape. Depending on the model drive, if the light does not extinguish when a new cleaning tape is inserted then there may be a hardware fault in the drive. Table 5 Symptoms of Using Expired Cleaning Media X - With DLT1/VS80 and VS160 there is no method to determine that the cleaning tape is expired except to manually note usage on the check box label. It is the customer's responsibility to record usage of the Cleaning Tape and discard after 20 uses. The cartridge has little or no effect on head cleaning after the recommended 20 uses.
