Scanner Problems
HINT: If you need
technical assistance for
your scanner, call the
scanner’s manufacturer
(see the documentation
that came with the
scanner for the correct
phone number). Dell does
not cover the scanner’s
warranty.
Modem Problems
HINT: Connect the
modem to an analog
telephone jack only. The
modem does not operate
while it is connected to a
digital telephone network.
CHECK FOR INTERRUPT REQUEST CONFLICTS — See page 47.
CHECK THE POWER CABLE CONNECTION — Ensure that the scanner
power cable is firmly connected to a working electrical power source and that the
scanner is turned on.
CHECK THE SCANNER CABLE CONNECTION — Ensure that the scanner
cable is firmly connected to the computer and to the scanner.
UNLOCK THE SCANNER — Ensure that your scanner is unlocked if it has a
locking tab or button.
REINSTALL THE SCANNER DRIVER — Reinstall the scanner driver. See the
scanner documentation for instructions.
CHECK FOR INTERRUPT REQUEST CONFLICTS — See page 47.
CHECK THE CONNECTION — Verify that the telephone line is connected to
the green connector on the modem. (The green line-in connector has either a
LINE IN label or a connector-shaped icon next to it.) Make sure you hear a click
when you insert the telephone line connector.
CHECK THE TELEPHONE JACK — Disconnect the telephone line from the
modem and connect it to a telephone. Listen for a dial tone.
CONNECT THE MODEM DIRECTLY TO THE TELEPHONE WALL JACK —
If you have other telephone devices sharing the line, such as an answering
machine, fax machine, surge protector, or line splitter, then bypass them and
connect the modem directly to the telephone wall jack with the telephone line.
