3M X75 LCD Projector

We have owned the X75 for awhile. It worked well at first but then the ink cartridges started failing. We cleaned and bought new but have not been able to get them working since. In addition, there are no generic (cheaper) replacements available for the ink cartridges. What happened is that Lexmark placed encryption in their cartridges so the printer only allows their cartridges (monopoly). From what I understand a company broke the code and started selling generics and Lexmark sued them and the court upheld it. That is why the price went down significantly until they were doing a 2 for 1 at $50 cost for awhile for this model. Most people know this now so this is for those that don't. I will not even by Lexmark any more after that.
