Problem Possible Solution
Image quality is poor or
has decreased
Make sure that:
• the scanner is clean. Refer to the Maintenance section.
The lamps shut off too soon The lamps in the i100 Series Scanners will turn off after 5 minutes of no scanner
activity. If the lamps are off, but the scanner has not yet gone into sleep mode
(default 15 minutes), there will be a delay of about 5 seconds for the lamps to
warm up again.
The default setting is 15 minutes, and if not changed to another value between
16 and 60 minutes, the lamps will turn off after 5 minutes of no scanner activity.
If you set the timeout to a new value greater than 15 minutes, you must scan at
least one document for that setting to be enabled. After this setting has been
enabled, it will be enforced until a new setting is selected or the scanner is
powered off and back on.

during scanning
Make sure that:
• the document side guides are adjusted to fit the documents being fed.
