Re: MP 501

Something dirty in the optics, DF glass probably, does it do it when scan off glass.

ADF registration. Change the registration or magnification (like bump magnification to like 102%) and see if it changes. Pretty classic problem for the A4 size devices.

It's catching the edge of the paper on the way out, when in color mode it picks up the shadow as blue. Change the registration a little each way till the line goes away. Registration will be off a little bit (1-2 mm) but the line will go away. Or just change magnification slightly larger to run the line off the page so to speak. I've never seen it personally on a 501 but have seen it more times than I can count on the SP5210, MPC 400 style scanner.

Re: MP 501

Not familiar with this box, but on other machines if the scanner glass is installed upside down or backwards, adf reg/feed issues will ensue.

That is usually due to the "scratch proof" coating on one side of the slit glass.

Re: MP 501

sorry
anyone who had this machine in field can do a test?
just put some originals in adf and do a scanner in color mode, and see if the cyan line appears.

i had the test in 3 diferentes machines and all did the same(cyan line in some,not all)

Re: MP 501

Have you tried what skinnyb suggested and have you checked the slit glass. It seems like you might be over complicating this problem. If you found other machines doing it, then it sounds like it's a built in problem with that product and often you have to find your own fix. Just because an adjustment is "spot on" doesn't mean you won't need to tweak it a bit to find a solution for a strange problem.

Leading edge Registration might be fine but if you make a copy of something OTHER THAN A BLANK PAGE, and compare it with the original, you'll see that the image is reduced. As suggested by skinnyb, adjust the ADF magnification in "peripherals"
