F-8 Compaq StorageWorks TL881/TL891 Family MiniLibrary System Reference Guide I Condition newly received cartridges in their operating environment for at least 24 hours before use. I Minimize potential damage from stray magnetic fields by ensuring a nominal spacing of not less than 3.2 in (80 mm) between the cartridge and the outer surface of its shipping container. Cleaning Guidelines See the following guidelines and Table F-5 for instructions on using the cleaning cartridge to clean the tape drive heads. I Under normal conditions, the cleaning cartridge is effective for 20 cleanings. If the cleaning cartridge has been overused, the Use Cleaning Tape LED may remain lit and no cleaning action takes place. When this happens, use another cleaning tape. I DLT tapes do no usually need regular cleaning, as their design allows for minimal head contamination. The action of loading and using any tape tends to clean the heads of the tape drive. I Use the cleaning tape no more than once every 2 weeks (or after 50 hours of continuous tape use). I When the Use Cleaning Tape LED lights, take note the tape in use at the time. This tape might be causing head contamination. Try another tape before using the cleaning tape, to see whether the Use Cleaning Tape LED stays on. I Use the cleaning tape more than once if a tape has severely contaminated the drive heads. If the problem persists after two cleanings, contact Compaq for service.
