Xerox patch pretested

A few minutes ago, Francis Tse mailed a preliminary version of the Xerox device software update to me. In a conference call with Rick Dastin, Francis Tse and others, and I installed the update on a WorkCentre 7545 and tested my test pages again.

The results seem nice so far: I was not able to see any mangled numbers on the scans of my test pages (of course, this is no guarantee at all, as I am not an image processing specialist – however, it is a lot better than before, where I was able to spot mangled numbers within seconds on every test page).

Xerox scanning issue fully confirmed, indeed software bug

Some happy news tonight (at least it's night for me): Rick Dastin and Francis Tse rang up a few minutes ago. Long story short:

  • It was a bug indeed,
  • the issue indeed affects all compression modes across a whole lot of devices, all are able to mangle numbers,
  • most important, they found the bug,
  • a patch is being developed,
  • and they want me to test it using my originals (this is an honor, I appreciate this).

Here is their press statement. I am glad not to go down in history as the guy too dumb to read the manual. 8-)

All three compression modes mangling numbers on Xerox WorkCentre 7545, reader reports also on 7655

As all of you probably know by now, the Xerox devices have three compression settings: Normal, higher and highest. Xerox claimed in their questions and answers sheet that the normal would be “the JBIG 2 setting” mangling numbers, and the rest would be safe at 200dpi resolution and above.

A few days ago, I found that on a Xerox WorkCentre 7545 in my hometown Bonn, besides the normal mode, also the “higher” compression mode was mangling numbers, even on a generous 300 dpi resolution. I reported my findings to Xerox, and after they tested it on one of their 7545s in the US, consequently seeing mangled numbers as well, I wrote a detailed blog post.

This already was in stark contrast to their on-screen notifications, their manuals (at least the ones I know) and even their current press statements, as all of these only issue character substitution warnings with respect to “normal” compression or even tell explicitly the user will be safe with the other compression modes.
