Troubleshooting guidelines When a problem arises with the CTS, test the CTS before performing any maintenance procedures to determine the problem and possible solutions.

  • Page 17: Troubleshooting Table

    1 Before You Begin Try the test cartridges in two or three different CTSs to ensure that any failures reported by EXPERT are CTS-related rather than tape-related. If a media error occurs, repeat the test with a known good cartridge to verify that the failure is CTS-related. After running EXPERT tests, refer to Table 1-1 in the next section to determine the maintenance procedures to perform.

  • Page 31: Determining When The Cts Needs Cleaning

    Determining When the CTS Needs Cleaning You should clean the CTS’s heads and tape path after every 30 tape motion hours. This cleaning frequency does not depend on the format in which you write and read data. However, if you are using the CTS in a particularly dirty environment, or if you operate it infrequently, you may want to clean the CTS more often than every 30 tape motion hours.

  • Page 32: Using The 8Mm Cleaning Cartridge

    Using the 8mm Cleaning Cartridge CAUTION To prevent contamination of the CTS and damage to the heads, do not use the cleaning cartridge for more than the number of cleaning cycles specified on the cartridge label. Discard the cleaning cartridge after you have used it for the specified number of cleaning cycles.
  • Page 33 Figure 2-1). Store the cleaning cartridge for future use if it still has cycles remaining. Or, discard it if no more cleaning cycles remain. Note: If the cleaning cycle was not successful, try another cleaning cartridge. Make sure you are using an EXABYTE or EXABYTE-approved 8mm cleaning cartridge. 510702...
