Scanner Problem
I have had an HP Scanjet 4470C scanner for quite a few years, which has given pretty good scanning results. I haven't used for a while, but, on scanning a photo yesterday, a faint moire appeared over the whole scanned photo, giving it a somewhat washed out appearance , as well as a series of closely spaced lines resembling the scanning passes over the document.
I've tried it with as high a resolution as 600dpi, (giving a huge file), but with no better results. I also tried it with different scanning software, with not much difference.
Between last use and this, unsatisfactory result, there has been absolutely no change to the scanner that I can think of.
Any suggestions?
