Chapter 2: Installing the Scanner 16
Cleaning Your Scanner
# In order to maintain the quality of your scanned images, regularl y clean the glass plate.
# Before cleaning, switch off the scanner by unplugging the power cord.
# Use a damp cloth and a mild detergent or alcohol to clean the surface of the glass plate.
# When you use sprays directly onto the glass plate, avoid the seams around the glass, as this
may cause the liquid to penetrate and contaminate the mirrors and lenses inside the scanner.
Do not use detergent on the plastic parts of your scanner.
# Especially the cleaning of the calibration slits in the holders is important. Keep this area dust-
and dirt-free.
SCSI Devices
Arcus 1200 is a Small Computer System Interface (SCSI) device. It c ommunicates with your
computer by using the SCSI-2 standard. The SCSI communication stand ard allows you to have
several peripheral devices connected to your computer.
Before connecting the SCSI devices you should always make sure that your computer and all SCSI
devices are switched off. If either the computer or any of the devices rem ains on, you could
damage the computer or the device.
A unique SCSI ID number is assigned to each device in the SCSI chain e nabling your computer to
identify the device it wants to communicate with and the priority of each device.
Caution: If two SCSI devices have the same ID number, your system will not work properly and
you may damage your SCSI devices. To avoid crashes, never use ex tension cables for SCSI
cables.
