NonStop NS-Series Operations Guide (H06.12+)

Cleaning System Components
This subsection contains basic information about cleaning enclosures, printers, and tape drives.
Many companies have service-level agreements with HP that include regular preventive
maintenance (PM) of their hardware components. If a Field Service Organization (FSO)
representative handles cleaning and other preventive maintenance for your company, you need
not be concerned with the cleaning tasks mentioned here.
Cleaning an Enclosure
Cleaning an enclosure is an infrequent task that you perform as required by conditions at your
site. Many installations require only occasional dusting. To dust an enclosure, use a lint-free,
antistatic dust cloth.
NOTE: Do not use solvents or spray products on any part of an enclosure.
If you need to clean an enclosure, use a cotton cloth and a cleaning product formulated for
computer equipment. Or use a damp cotton cloth and a mild, nonabrasive soap.
Cleaning and Maintaining Printers
Inspect all printers and replace the ribbons on line printers as needed. Replace the toner cartridges
of laser printers that are shared by the user community when print quality lessens. To remove
paper dust that can affect printer operation, vacuum printers periodically.
Cleaning Tape Drives
Clean tape drive heads and sensors frequently. For detailed information on cleaning tape drives,
refer to the documentation shipped with your tape drive. How often you clean a tape drive or the
tape path depends on use, operating environment, and tape quality. Cleaning supplies are
available from HP. Use these materials:
• Cleaning solvent: HP supports the use of only isopropyl alcohol (91 percent or greater) as
a tape-path cleaning solvent. Isopropyl alcohol cuts oil and grease, evaporates quickly, leaves
no residue, and does not damage the tape path.
• Nonabrasive, lint-free cloths and swabs.
• A cleaning cartridge, which provides a safe, convenient way to clean some types of tape
drives.
For ordering information, see the operator’s guide shipped with the tape subsystem.
