Bought printer in June and tried my extra toner cartridge but same results. Then the extra toner marks  seems to go away but not 100%. Still minor dots on back. Then it flares up again with tons of toner on back of print. Help

Toner on the back of prints will typically come from either the fuser or the transfer roller. If you examine the drum on the cartridge (the blue/green cylinder) does there appear to be left over toner on it. It should be clean with no traces of toner. If you remove the cartridge and look at the cavity of the printer, do you see any black power there? If yes, you likely have a faulty cartridge that has dumped toner in the printer and if it is a lot, the symptoms can go on for hundreds of pages until all the spilled toner moves out of the printer.
