4-1 Outline of maintenance
4-1-1 Routine maintenance
The routine maintenance is required for the MTU to keep its operational
performance at the specified level or more, and prevent an error generation
as much as possible.
There are various routine maintenance items from cleaning of the magnetic
head to be made at short intervals by the user, to replacement of the head
to be made at long intervals by maintenance experts.
The magnetic head cleaning is intended to remove the dirt and dust generated
by the movement of tape or under the severe environmental conditions as much
as possible, and thereby prevent data dropout or damage to the tape, thus
enhancing the reliability.
Therefore, the magnetic head should be cleaned periodically at the intervals
shown in Table 401 in order to secure the reliability of data.
For how to clean the magnetic head, refer to Item 2-1-6 of the instruction
manual.
The parts with service lives used for the MTU are recommended to be replaced
in assembly units every time they reach the recommended periods shown in
Table 403.
The parts should be replaced according to the individual relevant items
given in Para. 4-4 on referring to the precautions shown in Para. 4-2.
