CARTRIDGE PROCEDURES
Cartridges are precision devices.
They require careful
handling, proper storage, and periodic
cI
eaning in order to
prolong their usefulness and to ensure the integrity of the
recorded data.
The procedures given below are designed
to eliminate or to minimize damage to cartridges.
GENERAL HANDUNG PROCEDURES FOR CARTRIDGES
The following procedures generally apply to the handling
of disk cartridges:
1.
Keep the cartridge locked in its bottom cover when-
ever the cartridge is not in the disk drive. This prac-
tice ensures a positive dust seal and immobilizes the
disk inside.
2.
Do not place cartridges in direct sunlight.
3.
Replace covers that are crocked or otherwise damaged.
4.
Cleon the covers periodically with a clean lint-free
cloth (or Kimwipes®) to remove dust.
5.
Keep hands, pencils, clothing, and other objects off
the disk surfaces.
6.
Keep ashes, tobacco, and coffee away from cartridges
since ashes, tobacco, and sugar are prime sources of
disk contamination.
7.
To carry several cartridges at once, stack them on top
of each other. Do not carry more than five cartridges
at one time, however.
8.
If a cartridge is dropped, have it inspected by the cus'"
tomer service engineer before loading it in a disk
drive.
9.
Do not expose the cartridge to intense magnetic fields.
A field intensity of more than 50 gauss may cause in-.
formation to be lost.
Consult the customer service
engineer if high-intensity fields are suspected.
10.
Before using a cartridge, condition it to the tempera-
ture of the computer room for at least 2 hours.
The
conditioning time is required to ensure accurate track
registration, data recording. and data retrieval. This
is necessary only
if
the cartridge storage temperature
is less than 600 F or greater than 900 F.

LABELING CARTRIDGES
Cartridges may be labeled for identification.
It is recom-
mended that the top surface of the cartr idge be used for
labeling, although the outside of the bottom cover may
contain the some identification, if desired. Use the fol-
lowing procedures when label ing a cartridge:
1.
2.
Use a felt-tip pen, ball point pen, or an adhesive
label. Do not use grease pencils, cr.1ayons, or pencil:,s
to write on labels.
I
If adhesive labels are
to
be used, obtain only those
designed for use as disk labels.
Other labels could
loosen and damage the cartridge.
3.
Mark the label before placing it on the cartridge.
4.
Remove old labels. Do not apply a new label over
an old one.
5.
Remove any gummy residue left from an old label with
91 percent isopropyl alcohol and a lint-free cloth (or
Kimwipes) before applying a new label.
6.
Do not use an eraser to change the label. Rubber or
pencil particles could damage the disk surfaces.
7.
If the cartridge has been labeled with a felt-tip pen,
use 91 percent isopropyl alcohol and a lint-free cloth
(or Kimwipes) to change or to remove old markings.
8.
Do not put notes, markers, or identification cards in- ,
side the bottom cover.
INSPECnNG CARTRIDGES
Note: Use only Model 7254 Disk Cartridges or cartridges
that meet Xerox specifications.
When a new cartridge is received, and
wh~never
a car-
tridge is to be loaded in a disk drive, inspect that car-
tridge for possible defects. A damaged cartridge can couse
head-to-disk contact, and a single defective cartridge can
extend a malfunction to other drives and cartridges.
Use
the following procedure to inspect a cartridge before
loading it in a drive:
1.
Remove the bottom cover from the cartridge (see
Figure 19).
2.
Turn the cartridge upside down and hold it level.
3.
Locate the opening for entry of the read/write heads
and look for a black rubber plug that may be loose
or missing.
Caution:
Never allow the read/write heads to load
on a defective cartridge - the heads will
be damaged.
