Unlocking the Scanner
The scanner is locked at the factory. This is done to prevent the
scan head from moving a possibly damaging the scanner. Before
you connect the scanner to power, you will need to unlock the
scanner. There is a small plastic switch under the front of the
scanner. You will need to slide it into the unlock position. On
most scanners there will be small lock and unlock symbols.
If you do not unlock the scanner before plugging it in, it can cause
damage to the internal mechanism and render the scanner inoper-
able.
Connecting the Scanner to the Computer
Caution: Always turn off your computer when you are connecting any item to its ports such
as the scanner cable. This will prevent the possibility of any electical discharge damaging
either the computer or the item being attached (such as your scanner).
Connect the D25P Parallel Cable (the scanner cable) to the port on the scanner labeled PC and to the
parallel port computer. If there is another device (such as a printer) already connected to the
computer’s parallel port, disconnect it and refer to the section below. The cable can only be con-
nected one way, do not force the connection. The female end of the cable (with small holes) con-
nects to the scanner. The male end (with small pins) connects to the computer. Screw down the
connectors to ensure a good, tight connection.
To connect the scanner to your computer, you should use the cable that came in the scanner
package. The ImageReader PowerScan uses a specific type of cable characterized by a
“choke” around the cable close to the point where it plugs into the scanner. The cable filters
the signal going to the scanner in a way that is not supported by a normal cable. In addition,
parallel port signal is generally relatively weak and degenerates the further it travels. With a
longer cable, there may not be enough signal getting to the scanner to enable it to scan suc-
cessfully.
