Hi. My name is Brahm. I own a Lexmark C530dn printer. I bought it in the summer of 2007 from the Campus Computer Store at the University of Saskatchewan. It's an excellent color laser printer, and I really like it, but I have one problem - it prints a near-invisible matrix of yellow dots on everything I print.
I read about the dots, and read something crazy: that the dots could be used to encode information into every page you print, like the time and date you printed the document, and the serial number of your printer.
Not a big deal, right? This issue has huge implications on customer privacy. Imagine if every document you ever printed could be traced back to you - every resume, every letter, every assignment, every government document printed online. It would be equivalent to if every dollar you ever spent could be traced back to you, or if any act you ever committed anonymously could be traced back to you. It's an invasion of privacy, and a violation of free speech by losing the ability to communicate with anonimity.
I feel that, in terms of my printing habits, I have nothing to hide, and will be updating with blog with "sensitive" information about my printer without hesitation. This includes my printer's serial number, which happens to be 9416FX1.
These webpages were my two starting links:

I'm starting this blog to document my experiences in contacting Lexmark customer support, or any additional information I stumble across. Please feel free to email me at email@example.com or leave a comment on this blog!
