Here are my understanding:
BD: Number substitutions happen on what machines? Do they happen on the default setting for the machine, or do you have to lower the quality and file size to get number substitutions?
A number of Xerox WorkCentre models exhibit this. At first it was reported that only the “normal” setting which is not the factory default setting caused this problem. But there are reports it happens at all settings.
Here is the latest from the German researcher:
BD: Did Xerox set up warnings for the user to know that substitutions could occur with those particular settings?
Yes, here is the reported warning,
“The normal quality option produces small file sizes by using advanced compression techniques. Image quality is generally acceptable, however, text quality degredation and character substitution errors may occur with some originals.”
BD: “What settings are required to create an automatic clipping mask that takes off the outer edges of the scanned document?”
That is actually two issues. The Xerox machines have a feature called EdgeErase which removes the edge of the document. It is designed to remove staple marks or three-hole punch marks. IIRC, the default is .1” This creates a white border around the edge of the document.
There is a clipping mask that is created by Preview when it is opened on a Mac. This is a separate border from the one created by the Xerox.
BD: “What settings create multiple layers, and are the layers created reproducible each time, or are they seemingly random? For instance, you lay the paper on the bed of the scanner.”
IDK the settings. The Xerox has a sheet feeder which would be the normal way it was fed into the machine. The blogger NBC did scan the same document three times and got three different results but I suspect that was using the sheet feeder.
BD: “If you save a scan on the 7655 without previewing it, is the saved file different than if you preview it on the 7655 before saving it?”
I don’t believe it has a screen for previewing the document before scanning like a computer hooked up to a scanner.
BD: “If you send the scan directly in an email is it in PDF format?”
From the Xerox manuals I seen, there are several file formats available including PDF, TIFF and JPEG. You can choose the format you want.
BD: “If they open it on a PC will they be able to move around pieces of content? If they open it on a Mac will they?”
As I understand it only if you open it in Illustrator.
BD: “If you import a digital file to the copier does the copier make layers out of a digital file as well, before printing it?”
IDK, can you even import a digital file?
Thank you. They need to do a controlled experiment by leaving the paper on the glass and scanning it different times to see if the algorithms do the same thing every time. If not, the algorithm is suspect. Why would an algorithm do different things in exactly the same circumstance? Do they create those things with volition? lol
