For the smaller office type of copier you can't beat the IR 5000.
Runs and runs .
Of course for high volume nobody can beat or match the docutech series of printers . Also, Xerox has the best color boxes on the planet , nobody has matched the quality of the IGEN and the Docucolor type of printer.
-that being said -
the document centre machines are the crappiest running machines I have ever attempted to work on. Always overtoned or undertoned, software always crashing ,Xerox always trying to keep the diagnostic software from third party vendors..
Canon has no software fees , doesn't take a pws to use diagnostics and the parts are easy to locate and purchase - that's why xerox is loosing the mid- volume copier market..
