Hello - I have a Samsung Xpress C480w from 2017. According to Samsung, this printer takes a K404S toner cartridge for printing in black, but when I install the K404S, I get the message “Toner not compatible” —- can someone please help with this issue? Thanks in advance"!
http://www.samsungdrivers.net/samsung-c4… As always with printers, try firmware update. Assuming you are using the original samsung cartrige, this should fix it.
