6. Troubleshooting
If you have any operational problem, please check the
following troubleshooting hints.
6.1 Questions and Answers
Question: Why the scanned image always comes out to be
too dark?
Answer: 1) Modify the Gamma setting to 1.8 for your
monitor and, when printing, set Gamma to
2.2 for your printer.
2) Use the Brightness setting of the TWAIN
user interface to get a brighter image.
Question: The scanning speed of my scanner is much
slower than that of those installed at other
computers. Can I speed it up?
Answer: Set you PC printer port to the EPP mode from
BIOS setting.
Question: Why does my scanner scan at a very low speed?
Answer: If you have installed Works for Windows, it will
install Window Printing System (WPS) in your
WIN.INI file. This will take up the printer port
time remarkably. You can remove the WPS
from your WIN.INI file, as follows:

Question: The printer does not print the documents. Why?
Answer: Pass-through printing may pose a problem for
some printers. It is suggested to add a second
printer card for printing purpose, or you may call
your authorized local dealer for further support.
Question: Does it take long for the scanner to initialize?
Answer: If your printer port supports SPP mode only, it
takes about two minutes for the scanner to
initialize. If your printer port supports EPP
mode, the initialization speed is much faster,
about 20 seconds.
Question: Why sometimes pass-through printing does not
work at all?
Answer: It may be that you fail to power on the scanner.
When doing pass-through printing, please be
sure to power on the scanner. Else, without
power, the scanner can not transfer the printing
data/signals to the printer.
6-3
Question: Why my GDI printer does not work with the
AV260C Plus?
Answer: Disable the Auto Scan function in the
application, then your printer will function in
normal working condition.
Question: Why some parallel port devices and software’s
keypro do not work with the AV260C Plus?
Answer: The AV260C Plus can do pass-through printing
all right , but the pass-through printing may not
work if you connect the parallel port with
devices other than printer. Therefore, if you
would like to connect some parallel port devices
other than printer, please do not connect them to
the same parallel port that AV260C Plus
currently uses. It is suggested to use other
parallel ports to connect these devices or
keypro. For instance, you can connect the
AV260C Plus to LPT1, and connect other
parallel port devices to LPT2. Or you can add a
data switch to avoid the problem.
