There is no mirror in the scanner. It is supposed to be clear glass. The light comes on to scan the item in the scanner.
Don't understand your problem. If the light does not come on the printer isn't plugged in or turned on when scanning.

As you probably know, your DLP (Digital Light Processing) TV works by projecting Red, Blue and Green light from three LEDs or a color wheel depending on your model, onto the DLP chip which contains rows of thousands of tiny mirrors. These mirrors reflect the colored light through some lenses and other fixed mirrors and onto the back side of the big frosted plastic screen on the front of your TV cabinet. In the neutral position, these little mirrors don't reflect any light onto the back of the screen. If they flex into a certain position they will reflect any light from the three LEDS shining on them. What color depends on which LEDS are on at that moment. Each one of the mirrors is roughly equivalent to a pixel.
Any mechanical thing will eventually fail and if any of these mirrors fails in the OFF position, then no light will be projected to that mirror's target on the big screen. You are not likely to notice one "pixel" on your screen being dark though. However, if any of the mirrors fail stuck in the in the ON position they will continuously reflect all three LEDs light to that mirror's target on the big screen. This little white dot is noticeable and your attention will constantly be drawn to that stuck mirror's white spot. Once one mirror fails it is only a short time before more and more mirrors stick in the ON position and you see dozens then hundreds of white specs. It's VERY annoying.
Fortunately, if you are fairly DYI handy, it's not a big job to install a new DLP chip (or LEDs for that matter) into your DLP rear projection TV. Do a BING search on the internet for the make/model of your TV and something like "how to change the DLP chip" in that make and model. There are plenty of YouTube videos on line that make the procedure very clear. If after watching the video you don't understand the procedure, that's an indication that you shouldn't attempt it. I've replaced two LEDs and the DLP chip on my Samsung 65" TV. That might seem like a bad thing but if you consider that the TV was 7 years old at the time and these seem to be the only parts that fail, it was worth it to more or less make the TV like new again. When you search for the parts, watch out for sellers with low part price but ridiculously high shipping cost. I found that Sears.com had the best price and shipping times for these parts.
