Toner is not compatible
When installed the printer says the toner is not compatible, but all the other remanufactured toners work fine.
For the issue ,could you try the following instructions to see if it could help work ?
Remove the toner cartridge from the printer. Turn it off for a minute and turn it back on then reinstall all the cartridge back into your printer. Make sure all the sealing tape are removed and the cartridge is sitting properly inside the printer.
