Troubleshooting
Indicator lights There are two indicator lights — one red, one green — on the scanner that
provides information about what the scanner is doing.
Green on — scanner is ready to scan
Green flashing — scanner is busy
Red on — an error condition exists (refer to “Problem solving” in this section
for help with some common error conditions)
Red and green on — scanner is powering up
After you power up the scanner, the red and green indicator lights will
illuminate. After approximately one minute, both lights go out. When the
green indicator light comes back on, the scanner is ready to begin scanning.
However, the host computer may require several seconds to detect
the scanner.
Service indicator lights After you power up the scanner both LEDs are on.
Red — CPU not running code. The red indicator will go out after about 30
seconds. This indicator will always be off, unless you are downloading
firmware or calibrating the scanner.
Green — the green indicator is on at all times.
