Multimedia Printer series

Thank you for purchasing the Multimedia Printer series drive MP7125A (hereafter referred to as the
drive). The drive enables you to play 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 MP7125A is the industry's drive that features Just Link. With this technology, the
MP7125A ensures stable writing operation even under circumstances where buffer underrun errors
tend to occur with conventional drives.

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.
