“Started having compatibility problems after several years with the usual replacement toner cartridges I had been purchasing for use in my color Xerox laser. Xerox nor Xerox authorized repair facilities would look at my printer unless the unreasonably priced original Xerox cartridges were installed and being used. Tried Professor Color cartridges after reading their technology claims and have had no further problems or need for repairs. Solved my issue at a price I can afford. Thank you !!”
