Storage? I am Storage!
My mom recently purchased a Microtek 4850 scanner from WorstBuy(special sale $99.99). Her reason for choosing that particular model was that it came with a slide and negative adaptor, and also that it is capable of 2400 dpi native resolution. Unfortunately, since it's USB and her Pentium doesn't have USB ports, it had to be hooked up to my machine. Good thing as well, since scanning negatives at 2400 dpi quickly uses up even the 768 MB of RAM in my machine. The 96 MB in my mom's machine would be totally inadequate, to say nothing of the 200 MHz processor speed.
Anyway, after hooking up the scanner it was only intermittantly recognized. I managed to do a few scans and then turned it off. For some stupid reason the light stays on all the time, making it necessary to "pull the plug" whenever I'm not doing scans. My older scanner only turns on the light whenever I acquire an image. Normally, this wouldn't be much of a problem, except that upon plugging it back in getting the scanner to initialize was hit or miss. At first I thought I might have a defective scanner but since it worked properly at least once I figured that probably wasn't the cause. Today when I tried to get the scanner to recognize the light only came on momentarily. On a whim I decided to check the voltage coming from the AC adapter. Sure enough, it was zero. Some more testing revealed that the voltage was intermittant. Jigging the wire made it rise to 12, and then for no reason it would start fluctuating. Evidently this is the cause of the problem, and my mom will try to exchange the adaptor tomorrow at WorstBuy.
What bothers me about this whole situation is why the f*ck does everybody nowadays insist on using these stupid outlet hogging adaptors instead of just running a power cord to the device and doing the voltage conversion internally(like my HP 940c Deskjet does)? And second, why does Microtek put what has to be one of the shitiest adaptors I've ever seen with what otherwise seems to be a fairly decent scanner(at least judging by the quality of the scans I've gotten)? And why does the light stay on all the time? If this isn't the single dumbest thing I've ever seen I don't know what is. Life of a cold cathode fluorescent tube is maybe 10,000 hours. My computer is usually on. This means a bulb replacement in maybe 14 months if I didn't notice it. Evidently engineers(and software designers) today lack common sense. The most important part of any electronic device is the power supply. A poor power supply can cause intermittant operation or worse. Why use an off the shelf adaptor that gives you no control over parameters rather than designing the power supply into the device? I doubt it adds much to the cost, especially considering the dissatisfaction and return rates this POS adaptor will probably cause. I can only hope the replacement adaptor will work better or else I'll be stuck building my own power supply for this thing.
