Solving scanning problems

Use the following table to solve problems with quality of scans. See

also “Solving image quality problems” and “Solving paper feed

problems” in this chapter.

Problem

Cause

Solution

The message on

the computer

screen says there

is a problem

opening scanner.

Unable to activate

TWAIN source.

You may have the wrong type of parallel

port, or it may not be properly connected

to the computer.

Another device is conflicting with the

parallel port.

Be sure that you have connected the

parallel cable that came in your package

to the correct parallel port on the back of

your computer. If you have another

parallel port, try attaching the parallel

cable to the other port. Make sure you

have an SPP- (bi-directional) or ECP-

compliant parallel port on your computer.

An SPP parallel port is the minimum; an

ECP parallel port is strongly

recommended. For more information on

your parallel port, please see appendix C

and your computer’s documentation.

The HP LaserJet 3100 product cannot

share a parallel port. If you have a sound

card, external hard drive, or network

switchbox connected to the same parallel

port as the HP LaserJet 3100 product, the

other device may be interfering. You must

unhook the other device to connect and

use the HP LaserJet 3100 product, or you

must use two parallel ports on the

computer. You may need to add another

parallel interface card. An ECP parallel

interface card is strongly recommended.

Please see appendix C or your

computer’s documentation for information

on installing an additional parallel

interface card or resolving conflicts.

No parallel port is

available or the

parallel port is

being shared by

another device.

The HP LaserJet 3100 product must be

directly connected to the computer’s

parallel port. It cannot share the parallel

port with another device.

If you have a device such as an external

disk drive or switch box connected to the

parallel port and want to continue using it,

you must get two parallel ports on your

computer.
