Multimedia Printer series

Thank you for purchasing the Multimedia Printer series drive MP9200A (hereafter referred to as the
drive). The drive enables you to play DVD-ROM or CD-ROM discs, write once and play CD-R discs, or
write, play, and rewrite CD-RW discs.

The following marks indicate media that can be used with the drive.

A new technology called Just Link incorporated
that overcomes buffer underrun problems

Buffer underrun errors that would occur when data transfer falls behind writing operation has been
inevitable for CD-R/RW drives. Just Link, which we at Ricoh developed on our own, is a new
technology that predicts possible occurrences of buffer underrun errors in advance and automatically
avoids them. The MP9200A is the industry's first-ever drive that features Just Link. With this
technology, the MP9200A ensures stable writing operation even under circumstances where buffer
underrun errors tend to occur with conventional drives.

New technology: (Optimum Write
Speed Control) function

When any write speed greater than 12X is specified, this function checks the media's capability to see
if it can be written at above-12X speeds. If the media is not capable of such speeds, the write speed is
reduced to 16X or 12X.

Caution

The JustSpeed (Optimum Write Speed Control) function is set to ON by default.
Depending on the ON/OFF setting of this function, the write speed is controlled as specified
below.

When the speed control is ON
Writing is performed at the speed of 16X in the lead-in area, at 16X from the 0-minute
position up to around the 5-minute position, and then accelerating up to 20X
approximately from the 5-minute position to the 15-minute position.

●

When the speed control is OFF
Writing is performed at the speed of 12X in the lead-in area, at 16X from the 0-minute
position up to around the 10-minute position, and 20X from around the 10-minute
position and after.

●

Obey the following cautions when handling the drive or discs.

Cautions During Installation

Install the drive in accordance with the specifications. Be careful to avoid locations
likely to cause vibration or shock.

●

Avoid locations where there is high humidity, excessive dust, or poor ventilation.●
Avoid locations in direct sunlight, with severe changes in humidity, or places where

there are extremely high or low temperature variations.

●

Don't use the drive near radio or television receivers. It may interfere with their
reception.

●

Do not disassemble the drive. Dismantling the drive to attempt repairs or for other
reasons is dangerous because the laser may radiate outside the unit.

●

Cautions During Use

Don't suddenly move the drive from a cold place to a warm place, or suddenly raise the
room temperature. Condensation may occur, causing abnormal operation.

●

Make sure to remove the disc before moving the drive. The disc may be damaged,
causing data loss.

●

Be careful to prevent foreign objects such as liquids or metal from entering the drive.
Should by chance a foreign object enter the drive, please consult the dealer where the
drive was purchased.

●

Don't use benzene or thinner to clean dirt from the drive. Don't allow chemicals such
as insecticides to contact the drive. Use a soft cloth to wipe the drive, or moisten a
cloth with neutral detergent diluted with water and use it to clean particularly dirty
areas.

●

Don't cutoff the electric power while the drive is operating.●
When connecting two E-IDE devices to the Primary or Secondary connectors, make

sure that the two devices are not both configured as Master, or both as Slave. If they
are both set the same, Windows may fail to run or recognize the drives.

●

The total length of the E-IDE cable should be less than 18 inches (about 45 cm).●
Make sure the power to the host computer is turned OFF before connecting.●
Never insert a damaged disc into the drive.●
In wintertime, don't use a disc soon after bringing in from outdoors. Use it only after it●

has reached room temperature.

Cautions Concerning Disc Cleaning

Remove the disc by pressing the eject button.●
Use compressed air to clear dust from the disc. (Spray the compressed air for about 5

seconds).

●

Check to see if there is dirt on the surface of the disc. Be careful not to touch the disc
with the fingers when doing this. (See Fig. 1)

●

After cleaning the disc with compressed air, place it on the disc tray and mount it.(See

Fig. 2)

●

We suggest using dry air cleaner as compressed air for cleaning.●

Other Cautions

When moving the equipment, make sure that the disc has been removed from the
drive.

●

When connecting connectors, make sure that the power is OFF. If the power is ON,
there is a possibility of short circuit.

●

When not using the drive for a long period, dust may adhere to the disc tray. Before
using the drive again, use dry air cleaner to remove the dust from the tray.

●

Do not use any commercially available cleaning kit, because such a kit may damage
the drive.

Before installing the drive, please note the following points.

You will need the following:

A Phillips head screw driver of a suitable size to fit the securing screws for the drive unit.❍
The manual for the computer, to know the location of the IDE connector.❍

●

Turn off all peripheral devices of the computer, and the computer itself, and disconnect their
power cords from the wall sockets.

●

Discharge any static electricity by touching the computer covers etc.●
Before installing the drive, be sure to read the following cautions and information on preparation.

Keep a serial number label at the location specified by "READ ME FIRST".

3.

The drive can be connected as the Master or Slave on an E-IDE (ATAPI) interface.●
When several (up to four) E-IDE devices are connected, each must be set in a unique

way.

●

A hard disk is normally installed as the Primary Master on the E-IDE (ATAPI)
interface. Other E-IDE peripheral devices such as hard drives and CD-ROMs are then
set accordingly.

●

Caution

If two peripheral devices with the same settings are both connected to the Primary or
to the Secondary E-IDE bus, the host computer may fail to run, or may malfunction,
so careful attention is necessary.

●

Make sure that the host computer is turned OFF when connecting or removing a
jumper.

●

Must be connect the jumper in the vertical direction. If connected horizontally, the
drive may malfunction or be damaged.

●

Only one jumper should be installed on the jumper connector. If more than one
jumper is installed, the drive may malfunction or be damaged.
