For sale is one Source Tech ST9712 mono laser printer.
It is also marked on the back Lexmark 4514-230
The unit is new with 24 test prints done.  The toner is a starter
micr cartridge with 1.5K yield.


I have been told that these are lexmark printers that have been modified
by source technologies and that they are specific printers.  



I bought these from a government auction.  
The tags are marked 2013 so I hope these are still desirable.

That is all I know about them
