Hi dianabusk:
You have a bad K (Black) toner cartridge or the sensor is dirty,the sensors are located on the toner cartridge and in the machine where the toner cartridge seats. Try cleaning the sensors and/or replace the K (black) toner cartridge. The sensors are a silver color.

Hope this helps

Hi people,

we had the same problem and tried the above method, it didn't do the trick for us, but we went a bit further.

The place described with the little white plastic (under the blue lever) we took the little plastic plate of and cleaned the whole inside (the sensor is in there a, little hole). Put the plastic plate back and that was it. Hope if the above doesn't work, this will.

Try reseating the toner cartridge, it might not be in good. Reseat the whole drum unit (the part the toner fits into).

SOURCE: Check toner cartridge

Yes to non OEM's and those of you who are using them they cause heap em troubles.

It can be the drum they sit on, or toner dust on contacts of drums, machine base, and toner cart sides , also machine has eyes that get dusty, on machine frame at every toner/drum.
Pull out a tonerlook at side of handle there is a rectangle cut out silver/or black inside this lines up with "eyes" in side of printer frame, clean em.

I have also found a lot of import oki toners going around causing grief too, but fix is always sucessfull by A new gen non import toner and drum and ensuring contacts are free from toner dust.

Another thing I find customers doing is not replacing toners when machine requests them ie at REPLACE TONER, instead they find that just openning and closing lid keeps them going, but these machines hold a complete toner in the drum unit too, so all they are doing is depleting that and when they do finally provide a toner it goes straight into filling up the drum and therefore shortly will display repalce toner again.

Signgirl - your using OEM's so I suspect drum/contacts/eyes what % are t drums at and are they oem too?

Wendy - dont recommend aftermarket/refills all the money you save will be paid to someone like me to come and fix the problems they end up causing.

OKiproblem - ever use aftermarket carts/drum, and what are % of consumables?

I received a message "543:


this means that the toner chip on the black cartridge is defective and theres really nothing you can do other then get another black toner to replace it with. some companies do sell the chips but probably easier to return where you bought it and get a new one to replace it. The company ,if reputable shouldnt charge you for another one but just exchange it with a working toner... Please mark as FixYa! if this helped...Get Paid To

Suggest you order a black drum, which may include a black cartridge. Replacing BOTH the cartridge and the drum should solve the sensor problem, then you can swap parts to isolate where the problem is.
