scanner is scanning off center though the image is perfectly straight, Epson 3170
I was scanning a baseball card. I put a clear piece of plastic on the surface of the scanner to keep from getting it scratched. I centered the card right in the middle of the top of the scanner which is 9 inches.
The resulting scan was tilted.
If the middle and top of the card was "12 on a clock" the scanned photo looks like the middle of the top of the card is now at 11 on the clock, as if it got moved before it was scanned. But, after scanning I opened the lid and the card was dead center like I left it.
What is causing the scanner to see this card at the wrong angle?
I have not made any adjustments to the scanner. I have used it "as is" since getting it:
for documents, coins and baseball cards and it has been working fine.

I don't want to steer you into the wrong direction, since some scanners use an "auto skew" adjustment. And this may not even be your problem, but as a copier/scanner technician I would start with the mirrors and making sure they are perfectly parallel after of coarse using a test pattern that would verify the skew is not software related. Your printer may have a "transportation" lock on the back of the unit, which usually does not get used when you are actually moving the device.
Did you recently move the device where it may have got handled a little rough, or could it be a software "auto-skew" issue. What does it do on a normal page that is scanned?
If you think the mirrors are out of wack, there are usually alignment marks on the rails for the mirrors. I tried to find any documentation on the internet but could find nothing.

the scanner has not been moved since first put into use. It is on my desk and stable.
Some items I scan are 3 dimensional and not flat like a document.
However, I scanned a plastic storage case of coins and it was about 1/4 inch thick. The back end of the scanner lid raises up to allow for thick items.
This scan of the coin holder was perfect.
Later I scanned a baseball card in a protector plastic holder that was at most 1/16 of an inch thick. This image was cocked to the left, pointing northwest.
I just scanned a document with text, and it is straight as an arrow.

my error, looking for help with my last comment, not my last two.
Your original post states that the scan was not centered; but, still straight, and that will be a function of the page margins set in the software you are scanning the image into (i.e. a "centered image" will be shifted as the program added a .75" margin)
Your newer post seems to indicate the image is skewed (i.e. rotated xxdegrees)
Which is it?

I moved, and no longer have the scanned image that was off so many degrees.
It was cocked to the left maybe to the 11pm hour (as if it were a clock), when I was expecting it to be straight up at 12 on the clock.
I'll try to scan another baseball card, another coin, and a baseball card that has a white 8.5 x 11 piece of paper as a background.

>>white 8.5 x 11
Maybe white will work, but it might work better if there is typical text that the auto-skew can examine.

ok, I'll try that.

here is a baseball card scanned and the card is in a plastic storage case about 1/4 inch thick.

here is a baseball card scanned with a white background.

you can see the difference.
Is this mirrors?
or?

you notice that they are BOTH tilted.

the single card that was not in a plastic storage case, may have been off center when placed in the scanner, or moved slightly by opening and closing the scanner lid.
the card in a heavy plastic case is far more off center, and it could not have been moved by opening and closing the lid.
So, it seems the card on the white background, scanned properly, and the other one did not.

not trying to close the question, trying to award points.
system error?

no clear solution or the cause, not sure about adjusting mirrors, using a background for baseball cards is a help.
ASKER
meant to award 500 points but the system did not alert me that only 425 had be awarded.
