Installation problem: calibration process returns "bad calibration value"
Please try again to calibrate:
Make sure that you are using a clean white printer paper and check that its bottom edge is straight so it can be fed easily
into the scanner (no folded corners).
make sure that before you press the OK button to start the calibration, you place the white calibration paper properly so it
touch the scanner roller.
After you click OK the calibration should draw the paper in around 1 to 2 inches, straight, in 3-4 short steps and then eject
it backward. If the paper didn't go in the scanner calibrated the Black rollers of the scanner instead of the White calibration
paper.
You can repeat the calibration as many times as you wish, the scanner software will save only the last calibration attempt.
If proper calibration process does not resolve the problem, the most common reason is that the KeyScan software was installed
without having the proper Administrator privileges.
To resolve this issue:
Follow the instructions in "How to install software update for the KS810-P product".
o
Please note that if you download the latest KeyScan software from KeyScan website you must first download it to
the local hard-drive and run it as administrator from your hard-drive. If you attempt to run the installation direct
from the KeyScan website you will get the above error when you do calibration since the installation was not done
properly, when running installation from the web Microsoft degrade your user privileges from administrator to
regular user automatically and without any notification, this will cause bad installation.
Please make sure that you login using administrator user account and right click and select "Run As Administrator" when
activating the downloaded installation software.

Installation problem: Start scanning or calibration and the scanner stops in the
middle of document scanning and does not respond to any inputs.
The most common reason for such problem is that the KS810-P is connected to your PC USB port that does not comply with the
full USB2.0 standard performance, on some computers not all USB ports have the same performance either because of poor
internal cable leading to the front USB ports or because of BIOS settings.
Reasons and solutions for such problem:
The KS810-P is connected to the PC's front panel USB port. To resolve the problem try to connect the KS810-P to a USB2
port on the back panel of the PC.
o
Disconnect both the USB and the power cables from the KS810-P
o
Connect first the USB cable to the PC back panel port and after few seconds connect the power cable, the
connection order is important!
The KS810-P USB cable is connected to the computer through an external USB hub box or USB extension cable. To resolve
the problem:
o
Disconnect the USB cable and the power cable from the KS810-P.
o
Reconnect the KS810-P USB cable directly to the computer USB port on the back panel.
o
Connect the KS810-P power.
The PC has USB2.0 ports set on the BIOS to function as USB1.1 (or legacy mode).
To resolve the problem:
o
get support for your PC setting to modify the BIOS settings of the USB ports mode to full USB2.0 mode (not
USB1.1 and not Legacy).
