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.

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.

Caution. Do not use solvents or spray products on any part of an enclosure.
