Important notes
Preface
The DLT drive (MC80) is described in a separate manual (order number:
U25425-J-Z716-1-7400).
Further information
How to install the drives in the system unit is explained in the technical
description in your system unit product manual.
If the drive is already fitted in your system unit when shipped, the software is
automatically installed and configured when the system is first started up. In this
case you do not need to read the corresponding “Installation” and “Settings”
sections.
1.2
Important notes
V This description must only be used in conjunction with the manuals
“RM300 E / RM400 E - General Information“ and the product manual of
your system unit (“RM300 E - System Unit“ or „RM400 E - System Unit“),
as only these manuals contain the appropriate security information and
the procedure for installing the drives.
I It is important that you read the notes on RF suppression, electromag-
netic compatibility, and the suggested procedures for disposal and
recycling. This information can also be found in the manual “RM300 E /
RM400 E - General Information“.
These devices comply with the requirements of the EC directive
89/336/EEC regarding “Electromagnetic compatibility“. Therefore the
system is marked with the CE symbol (CE=Communauté Européenne)

Transport
Transport
V When you move the drives you must make sure that they do not contain
any volumes. With CD drives, the CD tray must be retracted to avoid
damage to the drive.
You are advised to keep the original packaging of the drives in case you
need to transport them.
Transport the drives only in their original packaging or other suitable
packaging which provides protection against impact and static
discharge.
The drives must only be opened by authorized specialist staff. Improper
opening can be dangerous to the eyes.

Operating the quarter-inch MTC drive
You should only open the drive flap when you wish to insert or remove a
magnetic tape cartridge. At all other times, the MTC drive (drive flap) should
remain closed in order to prevent dirt (e.g. dust) from entering the drive.

The access indicator always lights up when the MTC drive is active (e.g. when
the system checks whether a cartridge has been inserted, when a tape is being
rewound or wound forward, when data is being read from the tape or when data
is being written to tape).
V The drive flap must not be unlocked while the access indicator is illuminated.

Ê Check that the access indicator is not illuminated.
Ê Open the drive flap by pressing the release button.
Ê Insert the cartridge with the metal plate facing down and the tape aperture
to the left. Push the cartridge home into the drive opening.
Figure 5: Inserting a quarter-inch magnetic tape cartridge
The cartridge should protrude slightly from the drive opening after insertion.
V If you attempt to insert a cartridge incorrectly, you will encounter resis-
tance. Never attempt to apply force when inserting the cartridge into the
drive!
Ê Now close the drive flap.
The cartridge is now drawn in entirely. The drive flap must close fully.
Once the cartridge has been inserted, the tape is tensioned. This is done by
winding the tape backward and forward. Finally, the read/write head is located
in the MTC drive and the tape is again wound backward and forward a number
of times.
The MTC drive is ready for reading or writing once the access indicator is no
longer illuminated.

Handling quarter-inch magnetic tape
cartridges
Magnetic tape cartridges with a capacity up to 4 GB (QIC-4GB cartridge) are
available for the quarter-inch tape drive.
In order to achieve the best possible recording quality, it is recommended that
the magnetic tape cartridges supplied by your local Fujitsu Siemens Computers
office are used. These cartridges are precisely matched to the characteristics
of the drive.
Magnetic tape cartridges can be ordered directly by calling your local Fujitsu
Siemens Computers office (see the chapter “Accessories” on page 87).

2.4.1
Life of a magnetic tape cartridge
The life of a cartridge depends on the frequency with which the tape passes the
read/write head. The number of “head passes” is proportional to the quantity of
data transferred.
The following applies to quarter-inch cartridges with a capacity of 155 and 525
Mbyte.
A maximum of 5000 head passes can be performed.
The tape has 18 tracks. The entire length of the tape passes the read/write head
for each track. If 155 or 525 Mbytes of data have been written to this tape, the
entire tape will have passed the read/write head a total of 18 times. This means
that the cartridge can be written with 155 or 525 Mbytes of data approximately
260 times. If the data is read once for each time it is written, the life of the
cartridge is reduced to 130 complete read/write operations for 155 or 525
Mbytes of data.
Ambient conditions also have a considerable effect on the life of a magnetic
tape cartridge. You should therefore take special note of the following section
on the care of magnetic tape cartridges.

Care of quarter-inch magnetic tape cartridges
The correct way to care for magnetic tape cartridges is as follows:
●
Always store magnetic tape cartridges in their original packaging.
●
Before use, store magnetic tape cartridges in their operating environment for
at least 24 hours. If magnetic tape cartridges have been exposed to high
humidity or high temperatures, they must be stored in the operating
environment for at least three or four days. Cartridges which have not been
acclimatized are difficult to read and can attack the read/write head.
You should never treat a magnetic tape cartridge as follows:
●
Do not expose cartridges to direct sunlight or heat. The specified storage
temperature is between +5 °C and +45 °C. The ideal storage temperature,
however is 20 °C ± 5 °C with a relative humidity between 30 % and 60 %.
●
Do not allow magnetic tape cartridges to come into contact with magnetic
objects.
●
Do not use cleaning agents, solvents or thinners on magnetic tape
cartridges.
I As a general rule:
The following criteria cause a rapid reduction in the usability and
reliability of magnetic tape cartridges and MTC drives:
–
–
–
–
–
–
unacceptable temperatures
sudden changes in temperature
high dust levels (printer in the direct vicinity)
inappropriate handling or storage of cartridges
insufficient cleaning of MTC drives

4 mm MTC drives (DAT)
The 4 mm MTC drive allows you to read and write to 4 mm magnetic tape
cartridges. The format of these cartridges derives originally from the field of
entertainment electronics, which also gave them the name DAT (Digital Audio
Tape). However, since the requirements with regard to reliability are higher
when a tape is used for recording data than when it is used for recording music,
it is necessary to use special magnetic tape cartridges (see also the section
“Handling 4 mm magnetic tape cartridges”).
Up to 12 Gbytes of data can be stored on a 4 mm magnetic tape cartridge with
a length of 120 m if no compression is used. This MTC drive also allows data
compression, so that, depending on the type of data, between 8 and 24 Gbytes
of data can be recorded.

The indicators have the following meanings:
●
The standby indicator flashes when the MTC drive’s self-test is running
after the system has been powered up.
The standby indicator also flashes when the MTC drive is accessed during
normal operation.
The indicator is illuminated when a cartridge has been inserted and no data
is being sent to the MTC drive or when the tape is not in motion.
It is extinguished when no cartridge has been inserted.
4 mm cartridges require relatively long preparation and positioning times.
The standby indicator thus flashes for a corresponding length of time.

Operating the 4 mm MTC drive
The error indicator can display two different colors: amber or green. It only
displays green immediately after the system has been powered up. The
indicator is extinguished once the self-test has been passed.
If the error indicator flashes amber, the MTC drive should be cleaned without
delay, since it is no longer possible to guarantee correct operation.
If the error indicator is illuminated in amber, the MTC drive has a fault.
V You must not press the release button of the MTC drive if the data
transfer or standby indicator is illuminated or flashing. This can cause
loss of data.

Tips for avoiding problems during data
backup
If you observe a few important rules when using the 4 mm MTC drive and the
appropriate cartridges, you will avoid problems with the drive and will have a
reliable data backup device with an extraordinarily large capacity.
●
Eliminate any sources of dust or other impurities in the vicinity of systems
using 4 mm MTC drives. Paper and toner dust from printers and photocopiers is particularly aggressive.
●
Clean the MTC drive regularly and observe the sequence described in for
this drive in the chapter on “Care and maintenance”. Failure to clean the
drive or insufficient cleaning increases the read/write error rate, speeds up
wear on the tape and the head drums and can even lead to contaminants
being burned into the head drum. In this last case, even the use of a cleaning
cartridge will not rectify the problem; the drive must be sent into the service
center for cleaning and inspection.
●
Only use the MTC drive in streaming mode. This means that data is written
and read without stopping the tape.
Wear on the magnetic tape drum and the tapes themselves is increased
considerably if you do not observe this rule and instead use the MTC drive
in start/stop mode.
The MTC drive will operate in streaming mode if you
– perform backups at times when the load on the system is low;
– specify a block size ≥ 16 Kbyte in the backup command.
In addition, you should observe the notes in the section “Handling 4 mm
magnetic tape cartridges” regarding care of magnetic tape cartridges.

Handling 4 mm magnetic tape cartridges
Handling 4 mm magnetic tape cartridges
V Only use 4 mm magnetic tape cartridges which bear the symbols DDS
(Digital Data Storage) and MRS III (Media Recognition System). The use
of other cartridges can lead to incorrect operation. Refer to the chapter
“Accessories” on page 87 for a list of suitable 4 mm magnetic tape
cartridges. It is not possible to read or write to DAT audio tapes.
In order to achieve the best possible recording quality, it is recommended
that the magnetic tape cartridges supplied by your local Fujitsu Siemens
Computers office are used (see the chapter “Accessories” on page 87).
These cartridges are precisely matched to the characteristics of the
drive.

Figure 11: The symbols found on admissible magnetic tape cartridges
V 4 mm magnetic tape cartridges should only remain in the MTC drive for
as long as necessary. Store the cartridges in their original packaging,
which provides ideal protection against dust.
Magnetic tape cartridges can be ordered directly by calling your local Fujitsu
Siemens Computers office (see the chapter “Accessories” on page 87).
3.5.1
Life of a magnetic tape cartridge
The life of a cartridge depends on the frequency with which the tape passes the
read/write head. The number of “head passes” is proportional to the quantity of
data transferred.
The following applies to 4 mm cartridges.
A maximum of 1500 head passes can be performed.
One backup requires three passes of the tape, since the tape is deleted, written
and then rewound. This means that approx. 500 backup operations are
possible.
If, however, each of these backups is read once, the life of a 4 mm cartridge is
reduced to approx. 250 backup runs.
U26140-J-Z146-3-76
21
Handling 4 mm magnetic tape cartridges
4 mm MTC drives
If the MTC drive is working in start/stop mode, i.e. if the tape is regularly stopped
and the read/write head continues to revolve, the life of the cartridges is reduced
dramatically.
Ambient conditions also have a considerable effect on the life of a magnetic
tape cartridge. You should therefore take special note of the following section
on the care of magnetic tape cartridges.
3.5.2
Care of 4 mm magnetic tape cartridges
The correct way to care for magnetic tape cartridges is as follows:
●
Always store magnetic tape cartridges in their transport case.
●
Before use, store magnetic tape cartridges in their operating environment for
at least 24 hours. If magnetic tape cartridges have been exposed to high
humidity or high temperatures, they must be stored in the operating
environment for at least three or four days. Cartridges which have not been
acclimatized are difficult to read and can attack the read/write head.
You should never treat a magnetic tape cartridge as follows:
●
Do not expose cartridges to direct sunlight or heat. The specified storage
temperature for 4 mm magnetic tape cartridges is between +5 °C and
+32 °C. The ideal storage temperature, however is 20 °C ± 5 °C with a
relative humidity between 30 % and 60 %.
●
Do not allow magnetic tape cartridges to come into contact with magnetic
objects.
●
Do not use cleaning agents, solvents or thinners on magnetic tape
cartridges.
●
You should only leave a 4 mm cartridge in the MTC drive for as long as is
necessary. Since the tape in the MTC drive remains wound around the
read/write head, even small quantities of dust can cause damage to the MTC
drive.

8 mm MTC drive (7 Gbyte)
The 8 mm MTC drive is a system for writing to and reading special removable 8
mm magnetic tape cartridges. The format of these cartridges derives originally
from the field of entertainment electronics. However, since the requirements
with regard to reliability are a lot higher when a tape is used for recording data
than when it is used for recording video images, it is necessary to use special
magnetic tape cartridges.
8 mm MTC drives are particularly suitable for archiving large quantities of data.
The 8mm magnetic tape cartridges are written to magnetically and can be
deleted again as required. Errors during operation are corrected automatically
(ECC = Error Correction Code).
Up to 7 Gbytes of data can be stored on an 8 mm magnetic tape cartridge with
this MTC drive if no compression is used. This MTC drive also allows data
compression, which enables the recording capacity to be increased in relation
to the compression factor. The compression factor depends on the type of data
and is usually 2. In other words, 14 Gbytes can be recorded with this drive.
If the MTC drive is already fitted in your system unit when shipped, the software
is automatically installed and configured when the system is first started up. In
this case you need not read the chapter entitled “Installation“.

Notes on 8 mm MTC drives
This section provides information on how to avoid problems during data backup,
which magnetic tape cartridges are recommended, and how to handle the 8 mm
magnetic tape cartridges correctly.
6.1
Tips for avoiding problems during data
backup
If you observe a few important rules when using the 8 mm MTC drive and the
appropriate cartridges, you will avoid problems with the drive and will have a
reliable data backup device with an extraordinarily large capacity.
●
Eliminate any sources of dust or other impurities in the vicinity of systems
using 8 mm MTC drives. Paper and toner dust from printers and photocopiers is particularly aggressive.
●
Clean the MTC drive regularly and observe the sequence described in for
this drive in the chapter on “Care and maintenance”. Failure to clean the
drive or insufficient cleaning increases the read/write error rate, speeds up
wear on the tape and the head drums and can even lead to contaminants
being burned into the head drum. In this last case, even the use of a cleaning
cartridge will not rectify the problem; the drive must be sent into the service
center for cleaning and inspection.
●
Only use the MTC drive in streaming mode. This means that data is written
and read without stopping the tape.
Wear on the magnetic tape drum and the tapes themselves is increased
considerably if you do not observe this rule and instead use the MTC drive
in start/stop mode.
The MTC drive will operate in streaming mode if you perform backups at
times when the load on the system is low and you specify the following block
size in the backup command:
8 mm MTC drive (7 Gbyte)
block size ≥ 32Kbyte
8 mm MTC drive (20 Gbyte)
block size ≥ 64 Kbyte
In addition, you should observe the notes in the next section regarding care of
magnetic tape cartridges.

8 mm MTC drives
Handling 8 mm magnetic tape cartridges
In order to achieve the best possible recording quality, it is recommended that
the magnetic tape cartridges supplied by your local office are used (see the
chapter “Accessories” on page 87). These cartridges are precisely matched to
the characteristics of the drive.
V Use exclusively magnetic tape cartridges approved by Fujitsu Siemens
Computers and the manufacturer Exabyte® in the 8 mm MTC drive.
Other magnetic tape cartridges can damage the MTC drive. Never use
Video 8 cartridges.
The following magnetic tape cartridges are recommended:
8 mm MTC drive (7 Gbyte)
EXATAPE™, SONY QG112MA, SONY
QG160MA
8 mm MTC drive (20 Gbyte)
EXATAPE™ AME 170m
Magnetic tape cartridges can be ordered directly by calling your local office (see
the chapter “Accessories” on page 87).
6.2.1
Life of a magnetic tape cartridge
The life of a cartridge depends on the frequency with which the tape passes the
read/write head. The number of “head passes” is proportional to the quantity of
data transferred.
The following applies to 8 mm cartridges.
A maximum of 1500 head passes can be performed.
One backup requires three passes of the tape, since the tape is deleted, written
and then rewound. This means that approx. 500 backup operations are
possible.
If, however, each of these backups is read once, the life of an 8 mm cartridge is
reduced to approx. 250 backup runs.
If the MTC drive is working in start/stop mode, i.e. if the tape is regularly stopped
and the read/write head continues to revolve, the life of the cartridges is reduced
dramatically.

8 mm MTC drives
6.2.2
Handling 8 mm magnetic tape cartridges
Care of 8 mm magnetic tape cartridges
The correct way to care for magnetic tape cartridges is as follows:
●
Always store magnetic tape cartridges in their original packaging.
●
Before use, store magnetic tape cartridges in their operating environment for
at least 24 hours. If magnetic tape cartridges have been exposed to high
humidity or high temperatures, they must be stored in the operating
environment for at least three or four days. Cartridges which have not been
acclimatized are difficult to read and can attack the read/write head.
V You should never treat a magnetic tape cartridge as follows:
●
Do not expose cartridges to direct sunlight or heat. The specified
storage temperature is between +5 °C and +32 °C. The ideal storage
temperature, however is 20 °C ± 5 °C with a relative humidity between
30 % and 60 %.
●
Do not allow magnetic tape cartridges to come into contact with
magnetic objects.
●
Do not use cleaning agents, solvents or thinners on magnetic tape
cartridges.
●
You should only leave an 8 mm cartridge in the MTC drive for as long
as is necessary. Since the tape in the MTC drive remains wound
around the read/write head, even small quantities of dust can cause
damage to the MTC drive.
I As a general rule
The following criteria cause a rapid reduction in the usability and
reliability of magnetic tape cartridges and MTC drives:
–
–
–
–
–
–
unacceptable temperatures
sudden changes in temperature
high dust levels (printer in the direct vicinity)
inappropriate handling or storage of cartridges
insufficient cleaning of MTC drives
occasional use of inappropriate or spent tapes and cleaning
materials.

CD-ROM drive
A CD-ROM drive allows optical data media (CD-ROMs) to be read. A CD-ROM
is read using a laser beam, with no contact with the disk itself. Unlike other data
media, it is not possible to write to a CD-ROM (ROM = Read Only Memory).
In the world of Reliant UNIX® systems, CD-ROMs are used primarily for distributing software. Nowadays, however, a wide range of other information, such as
directories of ZIP codes, spare parts catalogs and so on, is available on CDROM.
If the CD-ROM drive is already fitted in your system unit when shipped, the
software is automatically installed and configured when the system is first
started up. In this case you need not read the chapter entitled “Installation“.

CD-ROM drive
Handling CD-ROMs
Since no physical contact with the CD is involved in reading CD-ROMs, they
have a virtually unlimited lifetime. You must nevertheless observe a few points
with regard to care.
Care of CD-ROMs
When you remove a CD-ROM from its package, you should observe the
following rules:
●
If the CD-ROM is dirty, you can clean the surface carefully with a soft, dry,
clean cloth. Never use a damp cloth and never use cleaning agents or
solvents. Vapor near the CD-ROM (such as ammonia) can cause damage.
Most HiFi suppliers sell special cleaning cloths for CDs.
●
CD-ROMs can be damaged by direct sunlight or excessive heat (> 55 °C).
You should therefore never try to remove dirt using a hairdryer or similar. The
maximum rate of temperature increase per hour is 15 °C.
●
As with floppy disks, you must not bend or scratch the surface of a CD-ROM.
Avoid shocks.
Always keep CD-ROMS in their original packaging if not used.

Autoloader modes of operation
Autoloader modes of operation
The autoloader allows you to select magnetic tape cartridges in either of two
ways:
Cartridge selection from the front panel (stacker mode)
A magnetic tape cartridge can be selected by pressing buttons on the
autoloader’s front panel and loaded from the magazine into the MTC (magnetic
tape cartridge) drive.
I In this mode, the changer mechanism is not controlled by the software
but treated as a stand-alone MTC drive.
When the operation is complete, the magnetic tape cartridge is automatically
(controlled by software) unloaded from the MTC drive and returned to the
magazine. Then the changer mechanism automatically selects the next tape
cartridge from the magazine and loads it into the MTC drive.
Cartridge selection from the host (random mode)
In this mode, the host which the autoloader is connected to views the autoloader
as two devices:
1. A tape drive to which sequential access commands can be sent and
2. A tape changer mechanism to which medium changer commands can be
sent.
The controlling host computer has full random access to any cartridge in the
autoloader.

V Use only “DDS Media Recognition System” cartridges in the drive.
Between one and six magnetic tape cartridges can be placed in any of the
magazine slots. It is recommended, however, to place the first cartridge in slot
1 because during a sequential backup the drive will attempt to load the first
cartridge from slot 1, by default.
Ê Place the required number of cartridges into the magazine with the arrows
on the cartridges pointing towards the center of the magazine.
I Magnetic tape cartridges and replacement magazines can be ordered
directly by calling your local office (see the chapter “Accessories” on

I Any cartridge which is not DDS Media Recognition System will be
treated as write-protected.
Unloading the magazine and cartridges
When you press the Eject button on the front panel of the autoloader, the
cartridge is unloaded, i.e. moved from the MTC drive mechanism and replaced
in the magazine:
– The tape is rewound to the beginning of media (BOM) and unthreaded.
– The changer mechanism returns the cartridge to the magazine.
– The magazine is ejected.
The cartridge can also be unloaded by a command from the host. The same
procedure is followed but the magazine is not ejected at the end.
I The Eject button can be disabled by the software to prevent unauthorized
users from operating the autoloader.
Forcing ejection
Before you force ejection of a cartridge from the autoloader, read the following
caveats:
V You can lose data if you force an eject. Also, forced ejection may interrupt
drive activities, leaving the tape invalidly formatted.
Never use forced ejection as a quick way of obtaining a cartridge. Only
force an eject as a last resort to recover a cartridge when all attempts to
eject the magazine and cartridges in the normal way have failed.
However, if you need to unload a cartridge, even at the risk of losing data,
proceed as follows:
Ê Hold the Eject button down for at least 5 seconds.
The LCD will display Force Eject.

U26140-J-Z146-3-76
4 mm Autoloader
Loading/unloading the magazine and cartridges
The autoloader waits 35 seconds to give the normal eject procedure a chance
to occur. Once this time has elapsed, the tape is unthreaded and the cartridge
ejected from the MTC drive, regardless of what operation the drive was
performing. The cartridge is then returned to its slot in the magazine, and the
MTC drive is reset as though the power had been cycled. If no cartridge is
loaded in the MTC drive, the magazine will be ejected following the 35 seconds.

Equipment care
Your local office offers a comprehensive range of cleaning and maintenance
products for your system. The chapter “Accessories” on page 87ff lists the
various products together with their order numbers.
V Before you start cleaning work, switch off all equipment and make sure it
will not be restarted.
Make sure that no water gets inside the equipment.
Never use sprays, abrasive powder or cleaning agents which dissolve
synthetic materials.
10.1
Cleaning the CD-ROM drive
The CD-ROM is maintenance-free and does not require any special cleaning.
10.2
Cleaning cartridge tape drives
The intervals at which you need to clean the cartridge tape drives are based on
the length of time they are in use, the quality of the tapes and the environmental
conditions.
Inadequate cleaning or none at all increases the read/write error rate and
causes accelerated wear to the tape materials and the head drums, even to the
extent of particles of dirt being burnt into the head drum. If particle burn-in
occurs, the problem cannot simply be solved by using a cleaning cartridge. You
then need to send the drive to the your corresponding Service Center for
cleaning and inspection.
I Always clean the read/write head after using a new tape, because tape
abrasion may lead to read/write errors.

Equipment care
10.2.1 Cleaning the quarter-inch cartridge tape drive
Clean the read/write head of the quarter-inch cartridge tape drive with the
appropriate cleaning kit at the following intervals:
in use eight hours per day:
clean every day
used briefly every day:
clean once a week
used once a week:
clean every month
10.2.2 Cleaning the 4 mm cartridge tape drive
Clean the read/write head of the 4 mm cartridge tape drive, using only the
appropriate cleaning cartridge, at the following intervals:
in use five to six hours per day:
clean twice a week
in use three to four hours per day:
clean once a week
in use no more than two hours per day:
clean every two weeks
V If the error indicator flashes, you must clean the drive immediately to
prevent damage from dust particles.
The error indicator also flashes if, following a successful cleaning
operation, you use a tape on which the error rate is already too high.
Please clean the drive again if this is the case and do not use the
offending tape again.
The cleaning process takes approximately 30 seconds. If the cleaning cartridge
is ejected sooner, it is empty. In this case repeat the process with a new cleaning
cartridge.
Each cleaning cartridge can be used a total of 40 times. Note down on the
cleaning cartridge each time you use it so that you know when it is due to run
out.
Follow the instructions given on the packaging of the cleaning cartridge.

10.2.3 Cleaning the 8 mm cartridge tape drive
If the error indicator flashes (on MTC drive 8 mm 7 Gbyte) or glows (on MTC
drive 8 mm 20 Gbyte), you should clean the drive as soon as possible, since
even small amounts of dust can impair the functioning of the drive.
You should clean the drive at least once a month or after a maximum of 30
hours’ use.
V Only use cleaning cartridges that have been approved by Fujitsu
Siemens Computers and EXABYTE. Otherwise, the magnetic heads of
the drive may be damage
The following cleaning cartridges should be used:
– for MTC drive MC15: Premium cleaning cartridge 18c
– for MTC drive MC75: Mammoth cleaning cartridge 18c
Depending on its type, a cleaning cartridge must only be used 12 or 18 times
(Premium), or 18 times (Mammoth).
!
Do not exceed the maximum number of permissible cleaning procedures.
Otherwise, the drive or the read/write heads may be damaged.
Clean the 8 mm MTC drive as follows:
Ê Insert the cleaning cartridge.
Depending on the operating system, either cleaning starts automatically or you
must enter the following command at shell level:
Ê clean8mm devicename
This starts the cleaning operation. The operation takes approx. 1-2 minutes.
Once the cleaning operation is complete, the cleaning cartridge is ejected
automatically.
Ê Remove the cleaning cartridge.
Ê Note the date on the label provided.
This completes the cleaning operation.
You will find further information on cleaning on the cover of the cleaning
cartridge.

Troubleshooting
The following pages describe problems that may occur when you are using the
drives and suggest ways of solving them.
If the recommended actions are unsuccessful, try rebooting (switch the system
unit off and after about 10 seconds switch it back on again).
If rebooting does not help, inform your corresponding Service. Record all the
activities which may have caused the problem and any actions you have taken
so far in attempting to eliminate it.
