5-2 Prentive Maintenance
Terminals and Personal Computers
Clean terminals and personal computers and replace batteries on a regular basis. If battery replacement is
necessary, procedures and information are found in the terminal or personal computer user’s manual.
Printers
It is especially important to keep printer mechanisms clean.
Tape Drives
Clean the magnetic tape path at regular intervals to remove oxide build-up, especially on the read/write
head. Use only the prescribed cleaning fluids to clean the tape path. Improper use of non-prescribed clean-
ers can leave residue that can increase tape read/write errors and damage the tape drive and magnetic tapes.
Use only high quality tape media. Use of poor quality tapes can lead to loss of data and damage to the tape
drive.
Disk Drives
Check the PM procedures listed in the owner or operator’s manuals supplied with your disk drives. On
some disk drives, such as the HP 7937, it is essential to vacuum the filter.
Plotters
Clean plotters on a regular basis. Check the owner’s guide for preventive maintenance and cleaning
instructions.
HP Predictive Support
HP Predictive Support proprietary software is provided to customers that have a service contract. This pro-
gram (currently available only for the MPE-XL operating system) provides the customer with a preventive
maintenance tool to prevent system down time. The software reads and analyzes system and peripheral
error log files and prints a status report. The software sends data to the HP Response Center for analysis
and diagnosis. If the Response Center determines that on-site action is required, a CE is sent to the site. All
this occurs before the problem causes the system to go down.
For information about running the program, refer to the HP Predictive Support XL User Guide (HP part
number 50779-90001).
