You'll being seeing spots!
Reviewed in the United States on July 13, 2018
Don't buy, unless you like spots. Manufacturing defects on the green OPC drum in the Xerox toner cartridge (see photo) cause a line of black spots to be printed on each copy made. Three of the last four Xerox extra high capacity black toner cartridges (11,000 pages) 106R02313 have had this same defect. Poor quality control for such an expensive product (over $200 retail).
Since there is no way to fix a defective drum, these Xerox toner cartridges are essentially useless. If you're lucky, you may be able to return them to Amazon or wherever purchased. My calls to Xerox customer support have gone unanswered, so I'll probably have to abandon my Xerox copier/printer and switch to Hewlett Packard or another brand with more reliable quality for copying and printing.
