Frequently Asked Questions (FAQ)
Frequently Asked Questions are a collection of problem solving questions and solutions. If you are
having problems, looking in the FAQ might help you solve it. The FAQ is created using both those
questions we think you might ask and questions others have asked (with this or other scanners) and
the best solutions from Technical Support.
The FAQ is presented in a Question and Answer format to answer questions you might be having
about your scanner, its installation, and possible problems.
Setup & Installation
Do I have to have a special kind of port (or plug) to connect my scanner to my
computer?
Situation & Solution: The ImageReader PowerScan uses a parallel port connection. On most
computers, there is at least one parallel port (if you have a printer, this is the port that it also uses).
The ImageReader Ultra works with most port modes (the way a port passes a signal or communica-
tion from the computer to any device attached to it): Standard (SPP), Bi-directional (BPP), Enhanced
(EPP), and Enhanced Centronics (ECP). EPP is recommended as the port mode you that use with
the ImageReader PowerScan since it is the fastest.
My scanner cable is too short; can I attach a different or longer cable to my
scanner than the one that came with it?
Situation & Solution: You should use the cable that came with the scanner. Use of any other
cable is not supported by Info. If any damage occurs with the use of a different cable or if the scan-
ner will not operate with a different cable, it is not covered under warranty.
The ImageReader Ultra 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. Also, if you have a printer connected to the pass-through port on the scanner, a longer
cable for the scanner could decrease the operating ability of your printer.
Why does my scanner have two plugs (or ports) on the back?
Situation & Solution: Since the ImageReader PowerScan is a parallel port device, a pass-
