I have problems with scanners where I work. They do heavy duty scanning as in number of documents to be scanned and not a resolution thing. After sometime, of about 6months the scanner becomes really slow. I have explored all avenues and have come to the realisation that it is a hardware problem. I believe there is a component in the scanner that acts as a timer and it gradually gets bad. No matter what I do, installing a brand new system and attaching same scanner to it, it scans slowly at almost the same speed, including when the DRAM is doubled. Can someone help me out with the hardware component?

While I do not believe there is a "timer" in the scanner, there are components subject to wear, and dirt.

Start by making sure that the scanners you are buying are rated for continuous use.
If you are running the scanners more than 1 hour per day, you are wasting money buying sub $100 scanners.

Next, contact the manufacture, and get instructions for removing the glass and cleaning the inside of the scanner.
You want to clean both sides of the glass, the shafts or guides that the image sensor rides on, and perhaps the mirror and image sensor itself.

1 other component that could give you problems in a heavy usage situation, is the power supply for the scanner.
It might be worth it to work with an electronics tech and replace thepower supply with a higher power unit.
