Extra emphasis on backing pages w/ black paper

I can only repeat and emphasize ellias's advice. Please, please, please back the page being scanned with black paper. I find it excruciatingly painful to find a good scan marred by bleed-through from the other side of the page. Too bad this message won't reach the vast majority of scanners. (Who live in vain, ya know.)

I don't know about modern copiers (they're smarter than I am, but so's my dog), but older copiers would make a black sheet of paper when the lid was left up.

Today's tip for scanners concerns scanner artefacts. Consistent patterns of artefacts can be quite useful: they may indicate it's time we cleaned the glass on our scanner bed.;)

Is this the same problem as the moire pattern talked about previously? It really doesn't look like it to me. The first scan came out fine. The second, made a few minutes later looks terrible. And the third image is just a close-up of the second.

My cheap/crap printer+scanner's software can sometimes "lose"/forget settings such as descreen filter, etc., so is it possible similar may have happened to you? /shrug/ Not saying that's the fault just offering something to check/eliminate. /headscratch/

The first pic is a drawing, the second is a photo of skin. That makes a lot of difference for a scan.

First, make sure you use the descreen function. If that function doesn't help or is absent, change the resolution.
Last resort: scan at a high resolution, then shrink the image.

It looks like an electrical problem to me, which I've read happens to scanners. But I was hoping it was a moire problem because I can't fix a problem in the scanner. However...

I changed the resolution a few times, changed it to very high, shrank the image, and got a similar result. I don't have a descreen function. This problem did pop up after I moved, so maybe it's the current in the new building or the scanner got knocked somehow. Before I give up, I will try to take it to someone else's house. That should eliminate a few possibilities. Thanks all.

Help please! My new scanner is not giving me the qulaity I used to upload to VEF
 
I had to replace my old scanner which generally worked pretty well without me ever making adjustments.

I bought an HP OfficeJet Pro 6978. I thought the "69" would make it perfect for scanning porn of course.

Now my scans look like this:
That one was scanned at 200 or 300 dpi, and saved with 90% quality. I've tried 80%, 95%, 99%...all pretty crappy. I cannot seem to find any settings related to de-screening in the HP software I downloaded.

Any thoughts or advice? My contributions to VEF look like crap!!!

Thanks
