Improving scan speed

If the Stylus Scan is connected by parallel interface (available on
Windows machines only). The best way to improve the speed of
your scans is to make sure ECP mode is enabled on your system.
This is a system-level setting, so if you want to change it, contact
the manufacturer of your computer.
Always use the lowest Resolution (dpi setting) possible that will
still give good image quality. A higher dpi setting may not
increase the quality of a scan, but it will significantly slow down
your computer and it will require more disk space to save the
image.

Troubleshooting the Parallel Port (Windows 98/95)

Printing or scanning speed is slow

Make sure the ECP mode is turned on in your computer's BIOS.
For details, see your computer's documentation.
If the ECP mode is enabled in BIOS and printing and scanning are
still slow, the ECP hardware (a component inside your computer
which processes the ECP protocol) is malfunctioning. When the
Stylus Scan's ECP port driver senses a problem in the ECP
hardware, the driver switches to software processing of the ECP
protocol to protect your data. Software processing is secure, but
much slower than hardware processing.

A communication error occurs during printing or

scanning

Make sure the ECP mode is turned on in your computer's BIOS.
