7-6 Maintenance
Cleaning Optical Disk
A dusty optical disk or dust-accumulated tray causes the device to fail to read data correctly.
Follow the procedure below to clean the tray and optical disk regularly:
1.
Make sure that the workstation is powered (the POWER/SLEEP lamp is lit).
2.
Press the Eject button on the front of the optical disk drive.
The tray opens. Lightly hold the tray and pull it toward you until it stops.
3.
Hold the optical disk lightly and take it out from the tray.
NOTE:
Do not touch the signal side of the optical disk with your hand.
4.
Wipe the tray with a dry soft cloth.
IMPORTANT:
Do not wipe the lens of the optical disk drive. Doing
so may damage the lens and may cause a malfunction of the drive.
5.
Push on the tray front to close the tray.
6.
Wipe the signal side of the optical disk with a dry soft cloth.
IMPORTANT:
Wipe optical disks from the center to the outside. Use
only optical disk cleaner if necessary. Cleaning a optical disk with
record spray/cleaner, benzene, or thinner causes damage to the optical
disk contents. At worst, inserting the optical disk into the workstation
may cause failure.
