The Xerox TWAIN/WIA driver of the WorkCentre 6515 does support black and white scans with “Text/Photo” mode only. The scans use dithering, which is ok for photos, but is *not* ok for text documents. Dithering scans of Text documents produce text with interspersed white speckles in text letters.

WIA = Windows Image Acquisition. That is a Canon protocol for scanners - very strange for a camera. From personal experience (with Olympus), the camera simply plugs into a USB port and looks like a disk drive full of JPG files (or raw data).

Text in general appears rather grayish/white instead of black and white. Patch fr statistica 8 download full. The local user interface (LUI) does support scans in plain vanilla “Text mode” and will provide improved quality when scanning text documents compared to using 'text/photo' setting.

Currently, the 'Text mode' option is *not* available with the TWAIN/WIA driver. The Adobe Acrobat Support pages -> () emphasize: • “Scanning tips: Avoid dithering or halftone scanner settings. These settings can improve the appearance of photographs, but they make it difficult to recognize text. “ Whereas the WorkCentre 6515 does support plain vanilla black and white scanning via LUI setting 'Text mode', the current WorkCentre TWAIN/WIA driver supports black and white scanning with dithering only, i.e. Corresponding to a LUI 'Text/Photo' setting. Thus, the current design of the WorkCentre 6515 TWAIN/WIA driver does not conform to the Adobe recommendations, making it difficult to have the Xerox WorkCentre 6515 work properly together with an industry standard legacy product, viz. Adobe Acrobat or other OCR applications.

The Xerox WorkCentre 6515 may safely be characterized as currently actively hampering professional office applications. I’d appreciate a comment with respect to plans to amend the 6515 TWAIN/WIA driver, such that it supports a black and white “Text mode” as well. My apologies, but this forum is peer-to-peer and not monitored by Xerox support officially. I happen to be a 2nd level rep, and answer a lot of stuff here un-officially, but if you got through 2nd level to Engineering and they declined to fix it, there is no other avenue to use. Your only option at that point is to do a FER (Feature Enhancement Request), which is still through calling Xerox, but instead of reporting the matter as broken, you are requesting a feature be added, and again, there would be no guarantee it would get implemented unless you actually paid them to develop the feature. Probably cheaper and easier and certainly faster to switch to scanner from the device to an FTP server or SMB share which certainly will allow you to make the required change. >>Probably cheaper and easier and certainly faster to switch to scanner from the device to an FTP server or SMB share which certainly will allow you to make the required change.

Thanks for your reply. I'll look into this image retriever approach. It appears to hamper any office workflow substantially -> walking to the scanner - fiddle with the LUI - walk back to your computer and have Paperport fetch some scan from some preconfigured folder. That's my current impression at least. Pi kappa alpha risk awareness handbook of chemistry definition.

It's better, though, than jettison the WorkCentre alltogether for the time being. However, it should be clear to the community that at this time the WorkCentre 6515 is *not* recommendable for standard office applications, viz. Scanning black and white documents. I'll let you know what a call to support with respect to a FER will bring about.
