Assumption 6
You would prefer to focus your time on your business rather than managing and ordering toner cartridges, negotiating with copier reps, budgeting for new equipment, dealing with copier service techs, returning leased copiers and paying the 15% residual plus shipping, handling help desk calls, and dealing with break - fix issues.
There really is a more productive use of company time. Having one vendor you can count on every time really simplifies things.
