Re: Bizhub C452 Scanning issue

Do you get nicked edges or folded corners? Could it be a mylar?

I have had the same problem with the slit glass not getting into position but it will code out.

Did you first do adf guide adjustment?
Is your print and scan area correct?

Re: Bizhub C452 Scanning issue

Entire ADF on c452 is available as a spare part, I've changed many.

Might be an option if they want to pay for it ... but they aint cheap.

The glass cleaning section also comes as a complete unit too and pretty easy to change.

Hi Allan,

Thanks for suggestion. There is no folded or nicked corners on original before or during scanning.

No C-Code or any code for that matter related to the Slit glass movement. So I think, resp the machine thinks it reached HP. Sensor works btw.

Print area is fine, as I mentioned above the copy from the glass is fine. I have fed 99% of my test from bypass to avoid any skew during print transport.

Now regarding Guide Adjustments, Can you be more specific as to where or what do you mean by that. I digged out installation manual and followed procedures from there and stopped at the Auto Stop position adjustments in Main Scanning Direction as it messaged Unable.
If you mean physical adjustments a.e. Rear L&R Height Adjustments Yes I tried, Also the RH Side Hinge all the way to the Left and All the way to the right.
Also Played with the height adjustments of the Prohibited/LockTight screws on the actual reading section, which you probably thinking of as Guide adjustments .. Yes this did improve the skew but, the Auto Stop position doesn't work in Main Scanning direction.

Have a little Catch 22 here.. unless I swap parts.

I'll go first with the glass cleaning section from C650...if it fits great, if it doesn't I'll get new one.

We tried to upgrade customer, but nothing as yet.. so have to fix it.

The minimum and maximum width adjustment. Is under ADF somewhere. I get new setups that fails with the auto adjustment i you don't do that first.

Thanks Allan, I'll give that a try as well. Missed this in the Service manual. Cheers.
