Cleaning
To keep the driver in the best condition, regular cleaning is required.
Cleaning the read/write head
When the STATUS lamp is blinking (repeating a long ON and a short ON), clean the read/write
head within the driver.
Set the provided cleaning cartridge in the driver, following the procedure described in “Handling”
in “Setting the AIT Data Cartridge”.
When set in the Built-In AIT, the cleaning cartridge automatically starts cleaning the head.
After cleaning, the cleaning cartridge is automatically ejected (which requires about 35 seconds
after starting cleaning). Remove the cleaning cartridge.
Important
• Use our “AIT Cleaning Cartridge” to clean
the Built-In AIT. If you use a cleaner of other
manufacturer, a machine failure may be
caused.
• Do not touch the cleaning cartridge tape
surface or rewind the tape.
• You can use the cleaning cartridge for about
70 times. When the STATUS lamp blinks (at a
given interval) during cleaning, the cleaning
cartridge tape comes to the end. (Eject the
cleaning cartridge tape and check that all the
tapes are wound around the right reel.)
Purchase a new cleaning cartridge tape.
Hint
✎
Before using the AIT data cartridges, you should clean the read/write head using the cleaning
cartridge once a week. (The cleaning frequency varies depending on the operating environment
(generation of dust and dirt) and the operation frequency. When using the Built-In AIT every day in
a typical office, a weekly cleaning is recommended.)

Cleaning the Built-In AIT
If the Built-In AIT looks dirty, gently wipe its surface with soft cloth moistened with water or
detergent.
Important
Do not clean the Built-In AIT using chemicals such as benzine or thinner (volatile chemicals),
which may cause the unit to be deformed or discolored. For the same reason, do not spray
insecticide. If a chemical adheres to the driver surface, immediately wipe it with soft cloth
moistened with water.

Operation, Storage and Transportation Requirements
■ Operation requirement
Temperature : 5 to 45 °C
Humidity : 20 to 80 % (The maximum temperature of wet bulb is 26 °C.)
Shelf time : If an AIT data cartridge is exposed to an environment other than
the operating or storage environment, expose it to the operating
environment for a longer time than the period when it is exposed to
other environment (for 8 hours at maximum) before use. The
temperature gradient is 10 °C/hour.
■ Storage requirement
Temperature : 5 to 32 °C
Humidity : 20 to 60 % (The maximum temperature of wet bulb is 26 °C.)
Storage condition : Store an AIT data cartridge in a protective case with cover. You
can place the case horizontally or vertically.
■ Transportation requirement
Temperature : -40 to 45 °C
Humidity : 5 to 80 % (The maximum temperature of wet bulb is 26 °C.)
Temperature gradient : 10 °C/hour
Transportation condition : Store an AIT data cartridge in a protective case. During transporta-
tion, pack the case so that force will not apply to the AIT data
cartridge.
Label
It is recommended that you should affix a label to each AIT cartridge to associate the AIT data
cartridge with the backup data for easier identification.
Label paste position
20 AIT Data Cartridge
Precautions on entry to label
• To represent the data contained in the AIT data cartridge, use a label which can be easily
replaced and no adhesion trace is left.
• To change the label indication, do not erase it with an eraser but peel the old label and paste a
new one. (The INDEX labels are provided with the AIT data cartridge.)
• Pasting the label in the position specified in the previous section. To replace the label, peel the
old label and paste a new one.
• When using a label other than the specified INDEX label, its size should be the same as the
specified label.
• Enter the date when starting to use the cartridge in the provided INDEX label. It will help you
check the AIT data cartridge service life.
Write-protect
By setting the write-protect plug as
shown at right, the tape data can be
protected.
When you do not want to erase the
written data, set the plug to the “SAFE”
position (write disable). To enable write
to the tape, set the plug to the “REC”
position (write enable).

Precautions on Handling
Operational precautions
Before use
• If the AIT data cartridge is damaged, deformed or bent, do not use it.
• If the AIT data cartridge is exposed to an environment other than the operating or storage
environment, expose it to the operating environment for a longer time than the period when it is
exposed to other environment (for 8 hours at maximum) before use. If temperature is greatly
different between the storage site and the operating site, do not rush the cartridge into the
operating environment. Leave the AIT data cartridge in temperature of the operating site with
temperature gradient set to 10 °C/hour.
Mounting to the Built-In AIT
Set the cartridges as explained in “Setting the AIT data cartridge”. Close the empty protective case
firmly and store it in a place free of dust and dirt.
After use
Be sure to put the AIT data cartridge that you used in the protective case and store it in a place free
of dust and dirt. You can place it horizontally or vertically.
General precautions
• Do not touch a tape by hands. Do not
open or close the tape cover.
• Do not bring a substance which generate
magnetic close to the cartridge.
• Do not place the cartridge in a place
subject to direct sunlight or a place near a
heater.
• Do not apply strong shock.
• Avoid handling the cartridge while eating
or drinking. Take due consideration not
to adhere thinner or alcohol to the
cartridge.
Tape surface
Tape cover
• Insert the cartridge to the Built-In AIT gently and carefully.
22 AIT Data Cartridge
Usage Inhibition Standard
If an AIT data cartridge that you are using is in the case below, you must replace it.
• When the AIT data cartridge is given a strong shock, for example, when falling, and damaged.
• When the recording surface is contaminated with liquid, such as soft drink, coffee and tea,
detergent, metal chips or cigarette ash.
Important
If you insert an AIT data cartridge in such a condition into the Built-In AIT, the read/write head or
the driver itself may be damaged or contaminated, causing a machine failure.
Also, if you insert a new AIT data cartridge into the Built-In AIT whose head is contaminated or
scratched and you do not know about it, the AIT data cartridge may be contaminated or damaged.
In this way, damage is expanding.
Service Life
The service life of the AIT data cartridge varies greatly depending on temperature and humidity in
the operating/storage environment, dust and dirt, and head abrasion condition.
You can judge its service life in the following sequence.
• Assign a management number to a new AIT data cartridge. Enter the number in the AIT data
cartridge label.
• Create the AIT data cartridge management book. Record the date when each AIT data cartridge
is used and estimate how many years and how often each cartridge is used.
• Examine the AIT data cartridge management book and index label regularly. Discard the
cartridges having low reliability, for example, those which generate write/read errors.
The tape magnetic layer is composed of chemicals and it becomes deteriorated as the time elapses.
Although the tape service life, which is determined by this deterioration, varies greatly depending
on the tape storage environment (humidity, temperature), the tape is generally serviceable for about
3 years since you purchase it.
AIT Data Cartridge 23
Storing Important Data
When storing important data or programs, it is strongly recommended that you should prepare and
store the master tape and copy (backup) tape just in case.
Further, we recommend that you verify backup software when saving, and check saved data. For
details on verification, refer to the instruction manual for the backup software you are using.
By doing this, if one of the tapes causes a read error due to dust or dirt, you can recover the data
from the other tape. Thus, you can prevent loss of important data and programs.
Managing 3-generation Data
To store the data on the disk, you should manage the data in the three generations.
To manage the 3-generation data, use three tapes (A, B, C). On the first day, store the data on the
disk in tape A. On the second day, store the data in tape B. On the third day, store the data in tape
C.
This method allows you to protect your important data. For example, if tape C generates a read
error, you can use tape B to recover the data. If tape B generates a read error, you can use tape A
to recover the data.
