Questions and Answers
Question: When the scanner is powered on,
it makes noises and won’t stand
ready.
Answer:
There are two possibilities:
1) You might fail to push the scanner
shipping lock to its “unlocked” position.
If this is the case, pull the scanner
status switch to its “unlocked” position
first.
2) The scanner is not placed on an
even, flat desktop surface. This may
cause the scanner to malfunction.
