Re: scanner image whacked

Which way was main-scan & sub-scan on that image?

It looks like the optics are unfocused, possibly at the CCD. If the blurry area is at the trail edge of the scan (original image LTR-R orientation on the glass), the adjustment is in the sub-scan direction (adjusting the CCD height up/down at the left/right). If the blurry area is at the front or rear edge of the scanner (original image LTR on the glass), the adjustment is in the main-scan direction (adjusting the CCD height up/down at the front/rear of the machine.

Those are those red painted screws, but don't panic. Just keep track of the # of turns you make at each adjuster, in case you need to reverse what you did. It's a trial & error adjustment. Whenever I do it, I inevitably make it worse before I make it better.

Start with 1/4 turn of the adjuster at a time, until you see if you've improved the focus or made it worse. When it gets close, reduce the adjustment to 1/8th turns, then 1/16th turns ... until it's perfect. =^..^=

Tried lifting up on the front left corner of the scanner?

+1

the image is trapezoidal, so the scanner is out of alignment, someone has leant on it

Re: scanner image whacked

Agree with Deb. In olden days, you could pull off left scanner covers and push scanner to far left of machine and check for alignment. Not sure if still the case. The other thing to check is the leaf springs holding the mirrors in. Those could have been knocked out of place during cleaning. Back in olden days Ricoh used a glue that started to give away on ccd that would give a result like this.

I have also seen lazy customer employees lean on the front of the machine while they are using it.

Re: scanner image whacked

its not just the doc feed scanner,its on the glass as well, but i have pushed the scanner to re align it before but it was for registration issues not this... and where are the lred scews ? i can find any red adjustment screws in or around the lens, or the whole unit, in the back, or at the lens? please advise

When someone leans on the left front corner of the MFP it distorts the entire scanner frame,

Yep, that's why they put hard cardboards on new machines in this corner to support possible extra weight when machine is shipped or stacked.
I also really hate when someone pushes machine with hands on ADF...but people do it always.

Re: scanner image whacked

okay thats the ticket, it was way bent down, and i bent it back, good quality, but, the scanner is definitely loose in the corner, i can just lean on it and it moves down,, any fix for this? i guess if the client doesnt do a butt shot it should be okay

Re: scanner image whacked

also when i do an auto color calibration it fails,, no matter what, i had to re boot the machine to get the quality back

Definitely sounds like a ID sensor problem.
