BASIC USER MAINTENANCE
In this section you will learn how to maintain the
following types of public affairs office gear:

Your typewriter may have a rugged exterior, but
it is actually a delicate instrument. Treat it as such and
give it daily care. A typewriter in first-class condition
is easier to operate and turns out clean, crisp-looking
Keep your typewriter covered when you are not
using it. Clean it by wiping the outside with a soft, dry
Occasionally you should give your typewriter a
thorough cleaning. The frequency of these cleanings
depends on how often you use the typewriter and the
amount of dust in your office atmosphere. In general,
we recommend that you perform the following
procedures once a month:
Remove the platen or cylinder and wipe it with a
cloth moistened with a small amount of
denatured alcohol or cleaning fluid Do not wipe
off the alcohol; allow it to evaporate.
Remove the daisy wheel and inspect it for
damage and dirt accumulation. If necessary,
clean it with a short bristled brush. Using the
points of the bristles, tap the daisywheel lightly
to loosen the dirt; then brush it off lightly.
Remove the casing and clean the interior of the
typewriter with a long-handled brush or a soft
cloth. Brush toward the front of the machine.
Although microcomputer systems are small and
generally unobtrusive in the workplace, they require a
good deal of operator maintenance. Dirt accumulates on
diskettes, disk drives, printers, display screens and
keyboards. Static electricity also can be a major
problem, especially in areas where humidity is low.
Keep your microcomputer as clean as possible. One
way for you to do this is by using dust covers. This, of
course, only protects the system when it is not in use.
You will still need to clean the following components
on a regular basis:
l Floppy disk drive heads
l Display screen
FLOPPY DISK DRIVE HEADS. C1ean the
floppy disk drive heads with a head cleaning diskette.
The instructions that come with the head cleaning kit
may direct you to put fluid on the cleaning diskette; then
insert the cleaning diskette in the drive and activate
(lower) the heads for a few seconds. This helps reduce
service calls, and you are less likely to lose data. How
often you will need to do this depends on how often you
use the microcomputer and whether the area is very
Some floppy disk drive manufacturers recommend
cleaning the heads no more than twice a year. However,
we recommend that you clean the heads after 40 to 50
hours of actual use.
KEYBOARD. To clean keyboards, you can use
specially angled swabs with cleaning solution or a
portable vacuum cleaner (fig. 16-9) that has special
attachments to reach between keys. Vacuums of this
type usually have dual-filter systems to keep from
blowing dust and dirt back into the room. Ultra soft thin
bristle brushes also are available for cleaning keyboards.
