This error is toner not recognized
Follow the instructions for possible fix.

(1) Open the poly bag, and take out the Toner-cartridge.
(2) Remove the tape to the position like the figure.
(3) Hold the Toner-cartridge horizontally, so that the Lever-sensor may go up and down
(4) When it does not see the Lever-sensor like the figure, turn the gear in the direction of the
arrow, and it tries to see the Lever-sensor.
(5) Return the tape to former position.
(6) Put the Toner-cartridge vertically.
(7) Move Lever-sensor like the figure.
(8) Confirms the Lever-sensor is returned smoothly.
(9) Repeat (7) and (8), 3 times. The Toner-cartridge is wrong when the Lever-sensor does
not work from the position of (7) or when it does not return smoothly

We have put a new toner cartridge in our oki b710. it still reads 0% how do we reset?

There are some toners out there that do not have the "Chip" that makes contact with the printer itself. If you have the old cartridge then you can prize out the chip and fit it into your new cartridge. that will get it working again.

How to reset oki b411dn cartridge after refilling

Producers of printers protecting oneself against the mass copying of original toners implemented the number of solutions being aimed at hampering the copying of their solutions. Towards a number of recipes for individual sub-assemblies of the cartridge intended for a laser printer applying special scaling circuits installed in the casing of the toner which are suming the number of printed sides up was the most spectacular solution and are freezing the laser contribution after the achievement of set limit of printouts.

Hi, my Oki c5650 printer keeps coming up with C toner missing and also fatal error. Is there anything I can do? We are using refill toners for this printer, do you think this is the reason it keeps saying...

There is a sensor that detects the presence of the cartridge and also a chip reader attached to the LED scanners. First trick is to check the chip. Older machines often become less able to read after market chips. Locate the slot in the side of the cartridge at the end away from the locking mechanism. Carefully prise the cover off and slide out the RF chip inside the recess. Tape this on to the top of the cartridge directly above the recess. Put it back in the printer. and try it. This puts the chip closer to the chip reader and often fixes the recognition problem. A faulty sensor is more difficult to fix and would need a service technician who is more likely to recommend replacing the machine.

A message keeps flashing up 231 fatal error. Can you let me know what I need to do. 0116 240 3430 Dorothy

231 fatal error is telling you that the data from the chip on the toner cartridge is invalid or cannot be read.

This may happen for one of the following reasons:

1)The printer is unable to read the data on toner chip because of toner dust or dirt inside the printer.
Solution: Clean the printer inside, clean toner slot and drum.. See:Clean your laser printer.

2)Either the toner is not an original cartridge, it is refurbished or refilled, or the chip on the toner cartridge is defective.
Solution: replace the toner, or replace the Chip on toner cartridge.

3)The toner sensor in your OKI is defective.
Solution: Call the support number listed on the printer manual to arrange repair.

OKI B4400 toner - is the chip reusable? I get toner not installed

The chip is not reusable and needs to be replaced every time. You should be able to find a chip on the internet somewhere. I own a Cartridge World printer cartridge refilling store and I do not recommend refilling your own toner cartridges or buying super cheap ones off the internet. The toner is generally such a low grade that it degrades your drum cartridge causing you to replace a $219 drum unit before you should have to.

Error Message/Black toner empty

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.
