Howdy all, I have a HP scanjet 4570c flatbed scanner. I bought it used years ago and most of the time, it works just fine. On occasion tho, I get something weird. When I scan something, it adds some pinkish colored streaks. I took a scrap sheet of paper and scanned the back of it. I used a magic marker on some text that was there, also drew a smiley face on it as well. Anyway, the side with print is on the opposite side. Basically, it is also seeing the back side of the paper. I'm not sure if that could cause this weird streaking but wanted to mention it.
At first, I thought it was something on the glass so I disassembled the thing and cleaned it as best as I could. When I put it back together, I concentrated on the back side of the glass, since I have to disassemble it to clean it. I also clean the side the document goes on regularly. If it changed, I can't tell it. Another odd thing, the streaks change depending on the document. Sometimes you can barely see it, other times it is awful. I've not been able to reason out what makes the difference tho. I've got about the same results using Scanlite, Scanpage and XSane software. XSane may be a tiny bit better but it does vary at times. There's not a lot of settings available. I tend to use either 100dpi or 300 dpi for resolution thingy. I fiddled around a bit but it doesn't seem to help. This is a link to the page I described above. It's a little sizey so I didn't want to attach, for those who have email clients that puke a lot. lol https://freeimage.host/i/HTQLpWb You may notice that it is a little heavier at the top and gets lighter as it goes down. I've checked the glass, I can't find anything that would cause this. Is my scanner just going bad? Am I doing something wrong with a setting or something? Any ideas? Thoughts? Thanks. Dale :-) :-) P. S. After a couple weeks, my backup finished for that large directory on the NAS. I even did a update. It took a while but it's done. It would have been sooner but we had a power failure, or two. It got really cold here.
