Question about OKI C3400N Single Pass Color Printer
I have an OKI Data 3400n my friend filled the cartridge and it is still reading Black Toner Empty. What more can I do?
I have looked at all the solutions, some are partially right, none have worked yet. I have found a solution that works with aftermarket toners. The RFID chip is the problem, I had an aftermarket yellow toner that registered as empty, and could not get the printer to print, I took the RFID Chip off a black toner that had not been installed yet and placed it on the yellow toner
the printer recognized the yellow toner at 100%, further i swapped back the original chip and still the toner was at 100%
it worked, i had to search the net for instructions on changing the RFID chip very easy
hope this helps

Most all new color laser printers employ an RFID reader adjacent to each of the 4 tomer cartridges. There is a unique RFID chip inside (under a small blue slide cover) each toner cartridge. Whan a new toner cartridge is installed, the printer "knows" such and begins a "countdown" of the number of prints that are made which utilize the toner in each of the 4 cartridges. Once a toner cartridge has "processed" the predetermined number of copies you will get a warning that the cartridge is almost empty and must be replaced. After an additional predetermined number of copies are processed, the integral computer within the printer will shut down the printer until the cartridge is "replaced". If you simply "refill" the same or original cartridge and re-install it into the printer, the same RFID chip is in the cartridge and the computer will not reset the print "counter", allowing you to start printing. You have to obtain another couple of new or "re-filled" cartridges (of the same color or black) from an outside source. The printers' internal computer does not keep a complete running list of all of the RFID chips that have been installed and used in the printer (maybe 2 or 3) and then then it is "1st in / 1st out" of the limited RFID memory of the printer. I have been unable to obtain a "Service Manual" for the OKI C3400n printer to determine how to do a "hard reset" of the internal computer. I know there is a way which would allow the "refilling" of the toner cartridges without having to buy an additional 2 of each color.
