"CFLs" Compact Fluorescent Bulbs (with built in ballast) must be labeled as dimmable to be used on a dimmer circuit.
Traditional fluorescent fixtures must have a dimmable ballast installed inside and can be used with standard fluorescent lamps.
Fluorescent lamps must be sized to match the ballast. CFL's are matched at the factory, but others are not. Older fluorescent lamp fixtures have a ballast inside. A type rating is to operate (2) 48 inch / 40 watt lamps. Newer fluorescent lamps are rated for 32 watts, and these will not work - or will have a greatly reduced life.
If you installed CFL's, the first thing I would do is install regular incandescent lamps and see if it works as expected. If not, something else is wrong - otherwise - make sure you've got the right lamps in the fixture.
<span>• Always unplug your scanner before cleaning it. </span><br />
<span>• Place your scanner away from heating vents or windows, or other locations where moisture might affect its functioning. </span><br />
<span>• Always keep the scanner on a level surface so that it has a good grip, otherwise the mechanism carrying the CCD and fluorescent lamp may get damaged over time. </span>
In case Xerox 8830 scanner fluorescent does not shine the simpliest way try replace one or put this lamp on another working device and check if it work
Ok - a couple of things, first - when a dimmer is set to minimum; zero to a barely perceptible level of light output is expected. Second, fluorescent lamps have a much shorter range of dimming that the standard incandescent lamps have. It is not unusual for a fluorescent lamp to remain off until the dimmer is at or above the half way point in the dimmer's range. Third, you can not dim a fluorescent lamp or fixture unless the lamp or fixture is specifically labeled as being "dimmable". Use of a dimmer to control brightness of fluorescent lamps and fixtures that do not clearly indicate they are designed for dimming or to control the speed of motors like those in "paddle fan & light fixtures" creates a dangerous fire hazard condition. Most CFL (compact fluorescent lamps) that readily replace the screw-in incandescent type lamps and are clearly labeled as dimmable, can be used with a standard dimmer. The traditional (non-CFL) fluorescent fixtures that have a internally mounted and hard wired internal ballast need a special dimmable ballast to operate.
In my experience, when the lamp goes out, it's time for a new scanner. if you are willing to try and fix it though, maybe try Ebay or the manufacturer's website. You'll likely spend less time just replacing it though.
Just replace the lamp! It's just a fluorescent light you can get anywhere. You don't need a new scanner, if I had to replace the scanner every time the lamp died I be in the poor house!
The following White balance settings are available for the A2:
AUTO, Preset (Daylight, Tungsten, Fluorescent, Shade, Cloudy, Flash and Custom1 to 3)
The following slight adjustment is possible:
* At setting Daylight, Tungsten, Shade, Cloudy and Flash: +3 to -3 (one unit is approximately equal to a 10 mired shift.)
*At fluorescent lamp setting: equivalent to 7 fluorescent lamp(3 -wavelength colored fluorescent bulb, 3-wavelength white fluorescent lamp, 3-wavelength neutral white fluorescent lamp, 3-wavelength daylight fluorescent lamp, white fluorescent, neutral white fluorescent, daylight fluorescent lamp)
The following White balance settings are available for the A1:
