Cleaning the CTS

This chapter describes how to clean the CTS’s heads and tape path.
The CTS’s heads and tape path should be cleaned on a regular basis.
If you are experiencing write or read errors with your CTS, clean the
CTS using the procedures described in this chapter before you
perform any other maintenance procedures to see if cleaning corrects
the problem.

The only cleaning material authorized for use with the CTS is an
EXABYTE or EXABYTE-approved 8mm cleaning cartridge.

Important

Using cloth swabs, cotton swabs, cleaning agents, or cleaning
cartridges not approved by EXABYTE Corporation will void
the warranty on the CTS.

October 1992
