Tape Drive Head Cleaning Procedure
The following procedures should be used to clean the PBX T ape Drive(s). A T ape
Drive should be cleaned once every three months to reduce the risk of losing
information and to prevent unexp ected service c alls. An entry should be mad e in
the Lucent Preventive Maintenance Log when this is done (see Chapter 6).
A DC2000 Series Data Cartridge Tape Drive Cleaning Kit from 3M is used to
clean the tape head and the tape capstan. This kit c onsists of a Cleaning
Positioning Cartridge and 20 cleaning wands (Comc ode 406622464 or 3M
Reorder number DC051111-12947). A refill kit of 20 cl eaning wands is also
available (Comcode 406622 472 or 3M Reorder Number DC051111-12948).
NOTE:
