Setting scanner lamp controls
You can set the scanner lamp to use either Energy Save mode or
Faster Scan mode. These scanner lamp controls are available in the
HP ScanJet Controls control panel.
Energy Save mode
While in Energy Save mode, the scanner lamp stays on as long as the
software is running and might stay on for a while after the software is
closed. However, after about ten minutes, the scanner lamp
automatically turns itself off.
Because the scanner lamp automatically turning itself off, the scanner
conserves energy when Energy Save mode is enabled. (Energy Save
mode is the default setting for the scanner.)
To enable Energy Save mode
1 Choose Control Panels from the Apple menu, and then choose
HP ScanJet Controls from the submenu.
2 In the HP ScanJet Controls dialog box, click the Lamp tab.
3 Click Energy Save to select Energy Save mode.
4 When finished, close the HP ScanJet Controls dialog box.
Faster Scan mode
After the scanner lamp has turned off, it must warm up again before
the scanner can begin scanning. (This warm-up process takes about
30 seconds.) As a result, the time it takes to scan an item immediately
after the scanner lamp turns on is longer than the time it takes to scan
subsequent items.
To help prevent scanning delays caused while the scanner lamp is
warming up, you can enable Faster Scan mode. This mode allows you
to set a time (such as the beginning of your business day) when the
scanner lamp automatically turns itself on. The scanner lamp stays on
for ten hours and then turns itself off.
Because the scanner lamp stays on, even if you are not using the
scanner or the software, the scanner uses more energy when Faster
Scan mode is enabled.
To enable Faster Scan mode
1 Choose Control Panels from the Apple menu, and then choose
HP ScanJet Controls from the submenu.
2 In the HP ScanJet Controls dialog box, click the Lamp tab.
3 Click Faster Scan to select Faster Scan mode.
4 In the Select Time text box, type the time when you want the
scanner lamp to turn on. The scanner lamp turns on at this time
daily while Faster Scan mode is enabled.
5 When finished, close the HP ScanJet Controls dialog box.
