Hope this is kosher here, the Canoscan is just a flatbed scanner, no printer. But presumably shares tech with MFPs.
I have a Canoscan Lide 700f, probably over 10 years old, the manual is dated 2009.
I use it a few times a year to scan photos usually, for DTP. So I need good scans.
Last year I noticed banding, like pinstripes, in the scans. After a search I found this article:
How to calibrate your Canoscan Scanner in six frustrating steps - Fully Psyched
which documents the problem and gave a solution; which is to do a "platen calibration".
That did work, but I used the scanner again recently and the problem had returned. Again, the calibration cleared it.
So I am wondering what the cause is, and what "calibration" actually means and if it is going to eventually get unfixable.
I guess calibration means focusing the scanner so it exactly focuses on the paper surface on the platen.
Don't know though if this is a software or hardware correction.
Could it be that the scanner gets out of place when I store the scanner? I have been putting it in the box between uses, then stood it on its side.
So now I will store it horizontally, and also I will engage the lock which I have not routinely done.
If I do that, would it remain calibrated, or is this a precursor to it going out of whack regardless?
Of course I have started to look out for a replacement, but cash is tight.
