Cleaning the Magazine
The High Performance Cartridge Tape and Extended High Performance
Cartridge Tape subsystems are highly refined mechanical devices. To maintain
the maximum performance, the operator should take time to inspect and clean
the magazine and the cartridges. Damaged or dirty magazines or cartridges
can reduce subsystem reliability and cause the loss of recorded data.
Monitor the conditions of all magazines and cartridges for contaminants.
v Before inserting a magazine into the ACF, inspect the magazine for
contaminants. Wipe the exterior of the magazine with a lint-free cloth (PN
2108930) lightly moistened with Tape Unit Cleaner (PN 05H3929).
v Before inserting cartridges into a magazine, inspect the magazine cartridge
storage cells for contaminates. Wipe the interior surfaces of the cartridge
slots with a lint-free cloth (PN 2108930) lightly moistened with Tape Unit
Cleaner (PN 05H3929).
v Inspect all cartridges when either inserting or removing them from the
magazine. Clean any cartridge that has contaminates on the external
surfaces. See “Cleaning the Tape Cartridge” on page 70 for procedures to
clean the tape cartridges.
Note: Inspect cartridges and magazines when they are removed from a clean
environment. Clean them of any contaminates that may be present
before they may be inserted into a tape subsystem.
