If the scanner or software is not working, perform these steps first:
● Check that the power cable is securely connected between the scanner and a
live electrical outlet or a surge protector that is turned on.
● Make sure you have properly and securely connected the scanner to the
computer using either the universal serial bus (USB) or the parallel input/output
(I/O) interface. See "Using interface connections" on page 12.
● If the scanner is making a loud grinding noise, make sure the scanner is
unlocked. Move the lock to the unlocked position.
● Disconnect the power cable from the scanner and turn off the computer. After
30 seconds, reconnect the power cable and then turn on the computer, in that
order.
● If you receive installation file errors, or the scanning software will not run, make
sure all programs are closed and complete the following steps:
a If you have any previous versions of HP scanning software, uninstall that
software. (To uninstall the software, follow the instructions that came with
the software.)
b Double-click the Add/Remove Programs icon.
c Select the HP Precisionscan Pro software and click Add/Remove [for
Windows 95, Windows 98, Windows Millennium Edition (Me), and
Windows NT] or Change (for Windows 2000).
d After the welcome screen, double-click the Repair option on the second
screen. (Choosing Repair will reinstall the software with the same options
you chose the first time.)
e Follow the instructions on the screen.
f If you still receive installation file errors or the scanning software will not
run, uninstall and reinstall the HP scanning software. See "Uninstalling the
software" on page 22.
