bizhub C224e and C258 with crooked scans and copies

[mga]

If you have 2-3 copiers doing the same thing it is more likely you need to adjust the document feeder skew , not the scanner. I can't imagine 2 -3 copiers with the same scanner assembly issue (unless you have a tech that has been messing with the screws on the scanner when cleaning optics).

Very common on this model to have the adf skew adjust be off. There is a screw in the back right corner near the hinge for adjusting the way the adf is sitting on the copier. So, loosen the mount plate screw on the right hinge and then go to the rear of the adf and find the adjustment screw. Adjust that until the feeder is sitting straight on the copier , then retighten the hinge mount screw to lock in the adjustment.

And...it can be a little tricky. There is a lot of play in these feeders. When you lift the feeder to lock in the skew adjustment by tightening the mount screw,you must hold it steady or the adf can move and throw off the adjustment you just made.

Agreed also you don't want to start messing about with optics if you don't need to

blazebusiness, Absolutely! No way 2,3 machines with good ADF and bad scanner.
I have yet to see ONE machine with good(straight) DF copies and bad(distorted) glass copy.
But I may be just lucky

Nothing wrong with being lucky....lol. Here’s hoping your luck continues......May the L in your luck never be replaced with an F.

if u remove the right cover then remove the glass

then remove left cover and the front cover surrounding the scanner bed and remove a transparent film covering a screw hole u can manually pull the scanner so u can poke screw driver through hole to loosen the screw that hold the plate that clamps the scanner to the drive wire.

u will need trial and error micro adjustments of like 1mm until it looks good.

it can be time consuming and no doubt u will make it worse before it improves lol

Interesting, I am fairly confident this is not in the service manual though. I attempted to do this today, but could not find the screw you are referring to. It is probably in plain sight, but I do not see it. I know it would be some extra effort, but I would greatly appreciate a picture if possible.

If U take off left and right white covers U can then remove front white cover. The hole is around where that front screw is

You might also try lifting up the front left corner of the scanner (not the ADF, but the entire scanner unit). If some elephant were to lean on the ADF on the left side, it could cause the whole scanner to sag a bit on that left front corner. Just lift up on it a bit and see if you copies off the glass come out straight.

when the front left corner of the flatbed is visibly bent down, often you will also see shadowing on the edge of full A3 copies off the glass. In a pinch sometimes this can be remidied by pulling up the front left of the flat bed (risk of back injury) but ultimately the machine is trash in my opinion once this has occured, unless you want to goto hell and back swapping in a non twisted scanner. I'm thinking cost reduction happened on the 4 series onwards with thinner steel used as never really had these issues on the older models.

Love the precision adjustment of yanking up front left corner. The amount of times this has worked always surprises me.

So you where lucky NOT to have the BH-250/350 series and BH-C-253/353 series.......

They where notorious for their delicacy in that respect.

We did have those and i even owned a c-253 for home use, over here i never really had issues with the scanners. BH-350 series i changed a number of toner bottle drives and refoamed sticking clutches on them, millions of fusers and other usual nonsense. c253 series was annoying for transfer belt pressure retraction issues and the death sentance of clogged toner pipes. Mine still works but cant even give it away for free.
