Method for selecting and adjusting scanner illuminant

An apparatus, comprising:

• means for determining what type of power supply a scanner is connected to;
• means for selecting a high-power illuminant device when the scanner is connected to a high-power power supply;
• means for selecting a low-power illuminant device when the scanner is not connected to the high-power power supply, but is connected to a low-power power supply;
• and means for performing a scan using the selected illuminant device.

A scanner, comprising:

• a high-power illuminant device;
• and
• a low-power illuminant device, wherein each illuminant device is configured to scan a same side of a document, and wherein the scanner is configured to:
• select one illuminant device from the group consisting of the high-power illuminant device and the low-power illuminant device based, at least in part, on a level of power supplied to the scanner by a power source;
• adjust a scan speed based on the selected one illuminant device;
• and
• use only the selected one illuminant device in a single scan of the document.

An apparatus comprising:

• means for determining what type of power supply a scanner is connected to;
• means for selecting a high-power illuminant device when the scanner is connected to a high-power power supply;
• means for selecting a low-power illuminant device when the scanner is connected to a low-power power supply;
• means for adjusting a scan speed of the scanner based, at least in part, on the type of power supply the scanner is connected to;
• and
• means for performing a scan using the selected illuminant device and the adjusted scan speed.

An apparatus comprising:

• means for determining what type of power supply a scanner is connected to;
• means for selecting an illuminant drive setting in the scanner, wherein a high voltage setting is selected when the power supply comprises a high-power source, and wherein a low voltage setting is selected when the power supply comprises a low-power source;
• means for adjusting a scan speed of the scanner, based on the selected illuminant drive setting;
• and
• means for delivering power to an illuminant device using the selected illuminant drive setting to perform a scan at the adjusted scan speed.

A method of operating a scanner, comprising:

• determining what type of power supply the scanner is connected to;
• selecting a high-power illuminant device when the scanner is connected to a high-power power supply;
• selecting a low-power illuminant device when the scanner is connected to a low-power power supply;
• adjusting a scan speed, based at least in part on the selected illuminant device;
• and
• scanning a document using the selected illuminant device and the adjusted scan speed.

A method of operating a scanner, comprising:

• determining what type of power source the scanner is connected to;
• selecting an illuminant drive setting in the scanner, wherein a high voltage setting is selected when the power source comprises a high-power source, and wherein a low voltage setting is selected when the power source comprises a low-power source;
• adjusting a scan speed of the scanner, based at least in part on the type of power source the scanner is connected to;
• and
• delivering power to an illuminant device using the selected illuminant drive setting to scan an image at the adjusted scan speed.
